For a premium cold plunge pod with chiller, my best overall pick is the 1/3 HP 148-gallon AS ColdPlunge kit, which pairs generous capacity with a chiller suited to a full-size home tub. The 1 HP, 216-gallon kit stands out for buyers who need more room and cooling capacity, while the Diveblast kit is a distinct option for shoppers focused on a stated 39°F cooling target. The main tradeoffs are tub capacity, chiller strength, included circulation and filtration, and how much space the setup needs. A larger tub may fit more users but calls for more water and room; a smaller kit can be easier to place but may feel restrictive. Read on for the full breakdown and guidance on matching a kit to your space and use.

Key Takeaways
- The 148-gallon kits form the roundup’s strongest middle ground: they offer more room than the 87- and 100-gallon options without stepping up to the 216-gallon XXL tub.
- The 1 HP, 216-gallon kit is the capacity pick, not an automatic best choice: its larger tub and stronger chiller suit buyers who need that scale, but require more space and water.
- Chiller horsepower alone does not settle the comparison: the tub’s water volume, insulation, circulation, and the surrounding conditions all affect the cooling workload.
- The Diveblast listing stands apart by stating a 39°F cooling target: buyers should compare that claim with the other kits’ published specifications rather than assume every chiller reaches the same temperature.
- Included pump, hoses, and filter details matter: bundled circulation components can simplify setup, but buyers still need to check the exact kit contents and maintenance needs before ordering.

More Details on Our Top Picks
AS ColdPlunge Ice Bath Chiller & Cold Plunge Tub Kit, 1/3 HP, 148-Gallon Capacity
The 148-gallon tub is the main reason I’d rank this kit ahead of the smaller 100-gallon options for buyers who want room to settle into a full-body plunge. Its 1/3 HP chiller automatically maintains water down to 42°F, while the included pump and reusable filter reduce the need for manual ice and frequent water handling. Reinforced PVC, Oxford fabric, and EPE insulation give the flexible tub more structure and cold retention than a bare inflatable design. Compared with the similarly sized 1stplunge kit, this one lists an insulated lid and repair kit, but provides fewer published setup details. The tradeoffs are its substantial water requirement, assembly and plumbing connections, and a one-year warranty. The tub and chiller may also arrive separately.
Pros:- 148-gallon oval tub offers more room than the 100-gallon kits in this roundup
- Automatic chilling reaches temperatures down to 42°F
- Built-in pump, reusable filter, insulated lid, and repair kit are included
- Reinforced PVC, Oxford fabric, and EPE insulation support durability and cold retention
Cons:- Large capacity takes more water and space than smaller alternatives
- Requires setup and connection to an existing water source
- Tub and chiller may ship in separate packages, and the warranty is one year
Best for: Home recovery users who want a roomy, single-person plunge and have space and water access for a 148-gallon setup
Not ideal for: Apartment dwellers or casual users who want a compact, low-setup tub or do not want to manage a large volume of water
- Capacity:148 gallons
- Chiller power:1/3 HP
- Temperature:Down to 42°F
- Tub materials:Reinforced PVC, Oxford fabric, and EPE insulation
- Included components:Chiller, tub, insulated lid, pump, filter, hoses, fittings, repair kit, and storage bag
- Warranty:1 year
Our verdict“Choose this AS kit if you value extra tub room over a smaller footprint and can accommodate its setup and water needs.”
Ice Bath Chiller & 148-Gallon Cold Plunge Tub Kit for Cold Recovery Therapy
This 1stplunge bundle suits buyers who want a 148-gallon insulated tub with the core circulation hardware in one package: chiller, external filter, pump, and accessories. It cools to 42°F without relying on ice, making repeat sessions less dependent on buying and loading ice. The listing also specifies 110-volt power, a useful detail for checking a home outlet before choosing a system. Compared with the AS 148-gallon kit, it names an external filter and quick-connection setup, while the AS kit lists reinforced materials and an insulated lid. Neither is a compact option, and the 1stplunge tub is still a sizable one-person system intended for indoor or backyard placement. Its chiller and tub can arrive separately, and buyers need to plan for power, assembly, and the one-year limited warranty.
Pros:- 148-gallon insulated tub provides a spacious single-person plunge
- 1/3 HP chiller is designed to cool water to 42°F without ice
- External filter, circulation pump, and setup accessories are included
- 110-volt specification helps buyers check electrical compatibility
Cons:- Large footprint limits placement in smaller homes
- Chiller and tub may arrive at different times and require setup
- One-year limited warranty is relatively short for a permanent home system
Best for: Buyers who want a large, ice-free plunge kit and can verify access to a suitable 110-volt outlet and placement area
Not ideal for: People seeking a small indoor tub, a multi-person plunge, or a system that arrives as one easy-to-store unit
- Capacity:148 gallons
- Seating capacity:1
- Chiller power:1/3 HP
- Lowest stated temperature:42°F
- Voltage:110 volts
- Included system components:Chiller, tub, external filter, circulation pump, and accessories
- Warranty:1-year limited warranty
Our verdict“Pick this 1stplunge kit if you want a large ice-free setup and value its stated 110-volt power and external filtration details.”
Ice Bath Chiller & 100-Gallon Cold Plunge Tub for Home Outdoor Cold Therapy
With a stated operating noise of 40 dB, this 100-gallon kit is the lineup’s clearest fit for buyers who want a quieter recovery space. Its 1/3 HP pump, reusable filter, lid, and insulation are paired with a metal tub, offering a more defined structure than the flexible PVC-and-fabric tubs in the AS 148-gallon kit. The smaller capacity also means less water to fill than either 148-gallon option, though it gives up some room for movement. Cooling reaches 42°F, matching the temperature target of the other standard-power kits rather than the lower 39°F stated for the Diveblast model. The listed 33.5-inch footprint still needs a dedicated spot, and the product is described as outdoor-use only. Buyers should also expect some assembly and separate shipments for the tub and chiller.
Pros:- 40 dB operating-noise claim makes it a quieter stated option
- 100-gallon capacity uses less water than the 148-gallon kits
- Metal tub, insulated design, lid, pump, and reusable filter are included
- 110-volt operation is specified
Cons:- Product is described as limited to outdoor use
- Cooling is specified to 42°F, not the 39°F listed for the Diveblast option
- Separate shipments and assembly may add setup time
Best for: Outdoor recovery users who prioritize quieter operation, a metal tub, and a smaller water capacity than the 148-gallon kits
Not ideal for: Buyers who need an indoor-rated option, more tub volume, or a chiller specified to reach below 42°F
- Capacity:100 gallons
- Tub dimensions:33.5 × 33.5 × 29.5 inches
- Water temperature:42°F
- Pump power:1/3 HP
- Voltage:110 volts
- Material:Metal
- Listed operating noise:40 dB
- Features:Built-in pump and filter, insulation, portability, and lid
Our verdict“Choose this model for a quieter outdoor plunge with a metal tub, but skip it if indoor placement or extra-low temperatures are priorities.”
Ice Bath Chiller & Cold Plunge Tub with Pump, Hoses, and 87-Gallon Ice Pod – Home Recovery Kit
At 87 gallons, this kit uses less water and calls for less floor space than the 100- and 148-gallon tubs elsewhere in the roundup. That makes it the more practical capacity choice for a home with a defined plunge area, though its listed tub dimensions and weight describe the chiller rather than the assembled tub. The system is rated at 0.3 HP and is stated to cool to 42°F; the included hoses and pump support a complete setup, and the listing claims tool-free assembly in about ten minutes. The bigger hurdle is electrical: its 220-volt requirement is less convenient than the 110-volt 100-gallon model from B0FT8LQ5YD and calls for a compatible supply. It also requires periodic water replacement, so it may be less convenient for buyers who prefer filtered, low-touch water care.
Pros:- 87-gallon capacity is smaller than the other tubs in this group
- Cooling is specified down to 42°F
- Hoses and accessories are included, with tool-free setup claimed
- Listing states that filter replacements are not needed
Cons:- Requires a 220-volt power supply, unlike the stated 110-volt alternatives
- Water needs periodic replacement for hygiene
- Listed dimensions and weight are for the compact chiller, not the assembled tub
Best for: Home users with a compatible 220-volt supply who want a lower-capacity plunge than the 100- and 148-gallon kits
Not ideal for: Buyers without 220-volt power or those who want a larger tub and less frequent water replacement
- Capacity:87 gallons
- Power:0.3 HP
- Voltage:220 volts
- Lowest stated temperature:42°F
- Material:Metal
- Listed dimensions:11.4 × 11.4 × 12.6 inches
- Listed weight:43 pounds
Our verdict“Choose this 87-gallon kit if you have 220-volt power and want a smaller plunge; pass if electrical compatibility is uncertain.”
ColdPlunge 1/3 HP Ice Bath Chiller & 100 Gallon Cold Plunge Tub Kit
This AS kit is a straightforward middle ground for buyers who want an ice-free, 100-gallon plunge without committing to the larger 148-gallon tubs. Its 1/3 HP chiller maintains water down to 42°F, while the insulated lid and reusable filtration setup are intended to help keep sessions consistent between uses. The included hand pump, repair kit, and storage bag give it a more complete portable-kit feel than the B0FT8LQ5YD model, which lists a metal tub and 40 dB operation but not the same accessory set. On the other hand, this listing does not provide tub dimensions or a voltage specification, so buyers have less information for planning the installation than they do with that alternative. Assembly, water connections, limited portability, and possibly split delivery are the practical costs.
Pros:- 100-gallon capacity is a middle ground between the 87- and 148-gallon options
- 1/3 HP chiller automatically maintains temperatures down to 42°F
- Insulated lid and reusable filter support routine use and water care
- Hand pump, repair kit, and storage bag are included
Cons:- Requires assembly and connection to a water source
- Size limits portability once set up
- No voltage or tub dimensions are provided in the supplied specifications, and delivery may be split
Best for: Home users seeking a 100-gallon chiller-and-tub bundle with an insulated lid and basic setup and storage accessories
Not ideal for: Buyers who need verified dimensions or voltage before purchase, or want a lightweight tub that is easy to move regularly
- Model:AS-AY300-XL100
- Capacity:100 gallons
- Chiller power:1/3 HP
- Temperature range:Down to 42°F
- Included components:Chiller, ice bath tub, insulated lid, hand pump, repair kit, and storage bag
- Warranty:1 year
Our verdict“Pick this AS bundle if you want a mid-sized, accessorized home kit, but choose a model with published dimensions and voltage if installation planning comes first.”
AS ColdPlunge 1/3 HP Ice Bath Chiller & 100 Gallon Cold Plunge Tub Bundle
The AS ColdPlunge 100-gallon bundle is the straightforward pick for buyers who want the tub and circulation equipment together rather than assembling a system from separate parts. Its 1/3 HP chiller reaches 42°F, while the insulated tub and lid help limit heat gain between sessions. Compared with the 148-gallon Ice Bath Chiller & Cold Plunge Tub Bundle, this model takes up less room but gives up capacity; the larger tub is a better fit for users who want more space for full-body immersion. The LED touchscreen offers a simple way to monitor and adjust the water temperature, though the supplied details do not specify cooling time. Plan for assembly, and note that the tub and chiller may ship separately. Its one-year warranty is also shorter than the Diveblast’s two-year coverage.
Pros:- Includes the chiller, insulated tub and lid, external pump, filter, hoses, and fittings
- Cools water down to 42°F for repeatable cold sessions
- Insulated tub and lid help retain cold between uses
- LED touchscreen provides direct temperature monitoring and control
Cons:- Requires assembly and setup, which may be involved for a first-time owner
- Tub and chiller may arrive separately
- One-year warranty is shorter than the Diveblast model’s two-year warranty
Best for: First-time home plunge buyers who want a bundled chiller, tub, pump, and filter in a more compact 100-gallon setup.
Not ideal for: Tall users or households wanting extra room to stretch out; its 100-gallon capacity may feel limiting compared with the 148- and 216-gallon options.
- Model number:DY300-XL100
- Tub capacity:100 gallons
- Chiller power:1/3 HP
- Temperature:Down to 42°F
- Included components:Chiller, XL ice bath tub, insulated lid, external pump, filter, hoses, and fittings
- Temperature control:LED touchscreen
- Warranty:1 year
Our verdict“Choose this bundle for a complete, smaller-footprint home setup, but pick a larger-capacity model if you want more room in the tub.”
Diveblast Cold Plunge Tub with Water Chiller, Pump, and Filter – Cools Water to 39°F
The Diveblast Cold Plunge earns its place for buyers who need a tub suited to a taller frame: the listed fit accommodates users up to 6’7″, a useful distinction from the AS ColdPlunge 100-gallon bundle, which lists capacity but no height guidance. Its chiller can bring water from 90°F to 39°F in a stated 3–9 hours, although actual timing varies with ambient conditions. The 2/3 HP pump and 1,500 GPH flow rate provide circulation details that the other bundle listings do not give. In exchange, the product data provides less information about tub capacity and insulation than the 148-gallon Ice Bath Chiller & Cold Plunge Tub Bundle, making fit and heat retention harder to compare before buying. It also needs dedicated floor space, and its cooling window is not a fixed promise.
Pros:- Designed to fit users up to 6’7″
- Chiller is listed as cooling water from 90°F to 39°F in 3–9 hours
- Includes the water chiller, pump, and filter
- 2/3 HP pump and 1,500 GPH flow rate are specified
Cons:- Cooling time can vary with ambient conditions
- Product details do not state tub capacity or insulation construction
- Freestanding installation requires dedicated space
Best for: Tall home users, including people up to 6’7″, who want a bundled chiller, pump, and filter with a stated cooling range.
Not ideal for: Buyers who need a clearly stated large tub capacity or detailed insulation specifications before choosing a setup.
- Cooling temperature:Down to 39°F
- Cooling time:3–9 hours from 90°F, depending on conditions
- Pump power:2/3 HP
- Pump flow rate:1,500 GPH
- Listed user height:Up to 6’7″
- Material:Rubber-coated metal
- Installation type:Freestanding
- Warranty:2 years
Our verdict“Pick Diveblast if height fit is your main concern; choose a capacity-documented bundle if tub size and insulation matter more.”
Ice Bath Chiller & Cold Plunge Tub Bundle, 1/3 HP Water Chiller with External Pump & Filter, 148-Gallon Insulated Ice Bath Tub for Home Cold Therapy
This 148-gallon bundle balances more immersion room with the familiar 1/3 HP chiller class. The thick insulation and lid are intended to help the tub hold temperature, and its listed operating noise of around 40 dB makes it the most clearly specified quiet-running option in this group. Compared with the AS ColdPlunge 100-gallon bundle, the extra capacity gives users more space, while both list a 1/3 HP chiller and cooling down to 42°F. The tradeoff is a larger footprint: its listed dimensions are 47.2 by 25.6 by 25.6 inches, so it needs a suitable installation area. Buyers seeking colder water or a more powerful unit may prefer the PlungeFit 216-gallon kit, which lists a 1 HP chiller and 37°F minimum. This bundle’s one-year warranty and possible split shipments are worth factoring in.
Pros:- 148-gallon capacity offers more room than the 100-gallon AS ColdPlunge bundle
- Thick insulation and an insulated lid are specified
- Listed operating noise is around 40 dB
- Includes a 1/3 HP chiller, external pump, and filter
Cons:- Larger capacity requires more installation and operating space
- Chiller and tub may arrive separately
- One-year warranty is limited compared with Diveblast’s two-year coverage
Best for: Home users who want more room than a 100-gallon tub offers and value stated insulation and quieter operation.
Not ideal for: People with limited installation space or buyers who want a sub-42°F target and a higher-powered chiller.
- Water capacity:148 gallons
- Chiller power:1/3 HP
- Cooling temperature:Down to 42°F
- Tub dimensions:47.2 x 25.6 x 25.6 inches
- Tub material:Multi-layer PVC with reinforced frame
- Insulation:Thick insulation with insulated lid
- Noise level:Around 40 dB
- Warranty:1 year
Our verdict“Choose this model for a quieter, roomier plunge that targets 42°F, but look to the PlungeFit kit for colder water and more chiller power.”
Ice Bath Chiller & Cold Plunge Tub Kit, 1HP Cold Plunge Chiller with External Pump & Filter, Insulated XXL 216 Gal Ice Pod
The PlungeFit 216-gallon kit is the high-capacity choice for buyers who want a more powerful chiller and a colder stated target than the 1/3 HP bundles in this roundup. Its 1 HP chiller is listed as cooling to 37°F, while the 216-gallon tub offers substantially more capacity than the AS ColdPlunge 100-gallon and 148-gallon bundles. That added scale suits users seeking full-body immersion, but it also brings a practical penalty: the kit weighs 100 pounds, and its two-pack listing may mean coordinating separate parcels. The product description mentions filtration and indoor or outdoor setup, though the supplied specs do not give a cooling-time figure, tub dimensions, or a warranty. Compared with Diveblast, it offers a larger listed capacity and colder target, but less detail on pump flow and tall-user fit.
Pros:- 216-gallon capacity provides more space than the 100- and 148-gallon bundles
- 1 HP chiller is listed with a 37°F cooling target
- Includes an external pump and filter for water circulation and filtration
- Described for indoor or outdoor setup
Cons:- Listed weight of 100 pounds makes moving the kit difficult
- Requires assembly and setup
- Supplied product data does not state cooling time, dimensions, or warranty
Best for: Experienced cold-plunge buyers who want a 216-gallon tub and a 1 HP chiller with a stated 37°F target.
Not ideal for: Apartment users, frequent movers, or buyers who need confirmed cooling times, detailed dimensions, or warranty terms before purchase.
- Brand:PlungeFit
- Model number:FIT1000-XXL
- Capacity:216 gallons
- Chiller power:1 HP
- Cooling temperature:Down to 37°F
- Included components:1 HP chiller and 216-gallon ice bath tub
- Weight:100 pounds
- Material:Metal and PVC
- Number of packs:2
Our verdict“Choose PlungeFit for the roundup’s largest listed capacity and coldest target, provided you have room and can accept missing setup and warranty details.”
How We Picked
I compared the nine kits on the factors that shape daily use: tub capacity, stated chiller power or cooling target, circulation and filtration components, and practical fit. I gave more weight to combinations that appear balanced for a home setup than to a single large specification. Capacity affects room to sit and water volume; chiller power has to be judged against that volume, not in isolation. I also looked at whether the listing identifies a pump, hoses, or filter, since those parts can affect setup and upkeep.
The ranking favors kits whose listed configuration offers a clear use case and a sensible balance of scale and equipment. The 148-gallon 1/3 HP AS ColdPlunge kit leads as a broadly useful full-size option; the 1 HP, 216-gallon bundle ranks for buyers with a specific need for more capacity, rather than as a default upgrade. Smaller 87- and 100-gallon kits rank lower for shoppers seeking a roomy premium pod, though their reduced capacity may be a better fit for limited spaces. Where listings provide similar specifications or little distinction, I avoid claiming performance differences that the stated information cannot support.
Factors to Consider When Choosing Premium Cold Plunge Pod With Chiller
Product specifications only tell part of the story. Before choosing a chiller-and-tub bundle, I would check how it will fit your space, water routine, and expectations for temperature control. These broader points can prevent a capable kit from becoming an awkward or demanding home setup.
Match Chiller Capacity to Tub Volume
A chiller’s horsepower is only useful when considered alongside the amount of water it has to cool. A larger pod holds more water, so it can take longer to reach a target temperature and may place a greater ongoing load on the system. Ask the seller for cooling-time information under conditions close to your intended use, including ambient temperature and whether the tub is covered. Do not assume two 1/3 HP kits will perform identically just because the horsepower matches. A stronger chiller may be worthwhile for a large tub or frequent use, but it is not a substitute for checking the full system specifications.
Measure the Real Installation Space
Measure the tub footprint and leave room for access, plumbing, and the chiller itself—not just the space the pod occupies. Outdoor placement may call for a level surface, weather protection, and access to suitable power; indoor placement raises questions about drainage, water spills, and floor load. A full tub can be heavy, so check that the intended surface can support the filled setup before assembling it. Also plan a route for filling and draining, since a location that is hard to reach can make routine care tedious. A smaller-capacity kit can be the smarter purchase when a large tub would crowd the space.
Check What the Bundle Actually Includes
Listings may group a tub and chiller together while differing on the pump, hoses, filter, fittings, or other connection parts. Confirm the included items and their specifications before assuming the kit is ready to run. Check whether the filter type and replacement parts are available, and whether the plumbing connections match the setup you can accommodate. Missing or incompatible components can add work even when the core equipment looks similar on paper. I would compare complete system contents rather than treating the bundle label as proof that every installation need is covered.
Plan for Water Care and Routine Maintenance
Chilling the water does not remove the need to keep it clean. Ask how the system circulates and filters water, what care the manufacturer recommends, and how often components need cleaning or replacement. Frequent use, multiple users, and outdoor debris can change the maintenance workload. A filter is useful, but it should not be treated as a complete sanitation plan unless the manufacturer says so. Before buying, make sure the upkeep routine and consumables are realistic for your schedule.
Set Expectations for Temperature and Recovery Use
A stated minimum temperature is not the same as a promise that the water will reach it quickly in every setting. Cooling depends on starting water temperature, tub volume, insulation, ambient conditions, and how often the lid is opened. If reaching a particular temperature matters to you, ask for the conditions behind the claim and whether the temperature is maintained during normal use. Consider your own comfort and cold-exposure experience instead of choosing solely by the lowest advertised setting. For health concerns or a new cold-exposure routine, seek guidance from a qualified health professional.
Decide Whether More Capacity Is Worth the Added Demands
A larger pod can feel less confining and may better suit taller users or households sharing the tub, but it also increases water volume and space needs. That extra capacity can affect filling, draining, heating or cooling time, and ongoing care. A compact tub is not automatically an inferior option if one person will use it and floor space is limited. Think through who will use the pod, how often, and whether a larger interior will change the experience enough to justify the extra footprint. Choose capacity for your actual users rather than buying the largest tub by default.
Frequently Asked Questions
Is a 1/3 HP chiller enough for a 148-gallon cold plunge?
It may suit a 148-gallon setup, but horsepower alone cannot tell you how quickly the water will cool or how well it will hold temperature. Results depend on insulation, starting water temperature, ambient conditions, circulation, and use patterns. Ask the manufacturer for cooling-time estimates and the test conditions behind them. If your location is warm or you expect frequent use, those details matter more than a simple horsepower comparison. Compare the complete system specifications before deciding that a 1/3 HP unit is sufficient for your routine.
Should I choose the 216-gallon kit over a 148-gallon kit?
Choose the larger kit if you need extra room for your body size or expect multiple household members to use it. That added capacity also means more water to manage and a larger footprint, so it can demand more from your space and routine. The 216-gallon option in this roundup pairs its XXL tub with a 1 HP chiller, while the 148-gallon options generally use 1/3 HP chillers. That difference makes the larger bundle a more specialized choice, not an automatic upgrade. Measure first and confirm the chiller’s performance expectations for your intended conditions.
Does a bundle with a filter mean I do not need a water-care routine?
No. A filter can help capture debris, but filtration and sanitation are not necessarily the same thing. Follow the manufacturer’s guidance for water treatment, cleaning, and filter care, and check whether the system calls for additional supplies or procedures. Your routine may vary with the number of users, use frequency, and whether the tub is indoors or outside. Before buying, review both the included filtration parts and the recommended upkeep so there are no surprises after setup.
Can I place a cold plunge pod indoors?
Possibly, if the room has enough space, suitable power, a safe floor, and a practical way to fill, drain, and handle spills. A filled tub is heavy, so verify the floor’s capacity rather than relying on its empty footprint. Leave room around the chiller and plumbing for airflow, access, and maintenance, following the manufacturer’s instructions. Indoor placement can also bring moisture and drainage concerns that an outdoor setup may not. Check the site requirements for the specific kit before bringing it into a finished room.
How should I compare a listed 39°F target with kits that do not state a temperature?
Treat the stated target as useful information, but ask under what conditions the chiller can reach and maintain it. A temperature figure does not explain cooling time, the effect of warm surroundings, or how the system performs with a full tub. For kits without a published target, request that information rather than assuming their limits match another product’s. Compare capacity, insulation, circulation, and the manufacturer’s performance details together. If a specific temperature is a firm requirement, choose only after the seller clarifies the conditions behind its claim.
Conclusion
For most buyers seeking a best overall balance, I would start with the 1/3 HP AS ColdPlunge kit with its 148-gallon tub. The best value direction is a 100-gallon 1/3 HP bundle when a smaller footprint matters more than extra room; compare the ColdPlunge and AS ColdPlunge versions by their included components and setup details. For a best premium, high-capacity choice, the 1 HP, 216-gallon insulated XXL kit makes sense for buyers who have room and want the larger format. Beginners may find a 100-gallon bundle easier to fit into a home routine than the XXL setup, while buyers focused on a stated temperature target should investigate the Diveblast kit’s 39°F claim and its test conditions. The 87-gallon option is a fit for space-conscious users, but those who want a roomier pod should favor the 148-gallon class.
