A chest freezer can look like a budget shortcut for a cold plunge, but the models below are food-storage appliances—not purpose-built, water-tight plunge tubs. The product details do not confirm that any of them can safely hold bathwater. For a DIY setup, use a separate, properly supported waterproof tub or liner and keep water away from the freezer’s electrical parts; a dedicated cold-plunge tub and chiller is the safer, more straightforward option. If you’re comparing freezers for a carefully planned conversion, these picks offer different storage capacities and temperature controls, but check the manufacturer’s guidance before using one near water.

Our Picks: Best Chest Freezer For Cold Plunge reviews
Hamilton Beach HBFRF2129: Best for Maximum Storage Space
The Hamilton Beach HBFRF2129 is a large, 21-cubic-foot chest freezer with a double-door layout. Its two separate lids give you more flexible access to stored food, while two removable vinyl-coated baskets help keep smaller items near the top. For someone comparing appliances as part of a DIY plunge project, the main appeal is its generous storage capacity—not any verified suitability for holding water.
The freezer has a seven-setting adjustable thermostat, an exterior defrost drain, a power indicator light, and a lockable external handle. Its aluminum interior liner is described as durable for freezer use. The supplied information does not provide internal dimensions, water-holding capacity, or approval for use as a plunge, so measure carefully and confirm the intended setup with the manufacturer before buying for that purpose.
Compared with the smaller options here, this model takes up more space and may be excessive if you only need a compact food freezer. Its double-door design could make access more flexible, but it does not address the core safety question: the appliance is not described as a water-tight bathing vessel.
Pros:
- Large 21 cu. ft. capacity for food storage
- Two lids allow more flexible access
- Two removable baskets for organizing smaller items
- Includes a defrost drain, power indicator, and lockable handle
Cons:
- Large footprint may be difficult to place in a small space
- Product details do not confirm water-tightness or plunge use
Verdict: Choose this Hamilton Beach model for high-volume freezer storage, but only consider it for a plunge conversion if a safe, separate water-holding solution is approved for your setup.
VEVOR 6.7 Cu. Ft.: Best for Electronic Temperature Controls
This VEVOR chest freezer has a 6.7-cubic-foot capacity and an electronic control panel with a temperature display. Its listed settings cover freezer operation from -15°F to 7°F and refrigerator operation from 32°F to 50°F. That control range is useful for adjusting the appliance for food storage, but the description does not establish that it can sense or regulate plunge water temperature.
Two removable baskets provide storage organization, and the balanced hinge-style lid is described as staying open for hands-free access. The freezer also has a condensate drain, leveling feet, and a stated operating range for ambient temperatures. Those are practical appliance features, but they are not evidence that the unit is sealed against bathwater or suitable for a person to sit in.
At 6.7 cu. ft., this is one of the smaller options in the comparison. That can make it easier to fit into a limited area than the 21-cubic-foot Hamilton Beach, though the product information does not give dimensions for confirming a particular location or plunge setup. Treat the display as an appliance temperature control, not a substitute for a separate water-temperature monitor.
Pros:
- Electronic controls with a temperature display
- Freezer and refrigerator adjustment ranges are listed
- Two removable baskets and a balanced hinge-style lid
- Compact capacity compared with the largest option here
Cons:
- Not described as a water-tight plunge tub
- Appliance temperature settings do not confirm water-temperature control
Verdict: The VEVOR is worth considering if you want a compact food freezer with electronic controls, but it is not a confirmed all-in-one cold-plunge solution.
muhub 10.0 Cu. Ft.: A Mid-Size Option with Simple Controls
The muhub chest freezer provides 10 cubic feet of storage in a mid-size format. A front-mounted seven-level dial controls cooling strength, and the removable basket helps separate smaller food packages from larger items. It also uses manual defrost, so routine upkeep is part of owning this model.
The product description lists a hinged door that opens between 45 and 90 degrees, leveling legs, and an R600a compressor. It also states a noise level of no more than 40 dB. These details may be relevant when choosing a household freezer, but they do not make the unit suitable for direct contact with plunge water. The supplied information does not list a water seal, immersion-safe electrical design, or water-temperature controls.
Its capacity sits between the compact VEVOR and Upstreman models and the larger TABU and Hamilton Beach choices. That makes it a reasonable size to compare for general food storage, though you should check its actual dimensions against your available space. For a cold-plunge plan, the bigger question is whether you have a separate, supported, water-tight vessel and a safe electrical arrangement.
Pros:
- 10 cu. ft. capacity offers a middle ground among these options
- Seven-level front dial provides straightforward adjustment
- Removable basket and adjustable leveling legs
- Manual defrost is specified in the product description
Cons:
- Manual defrost requires periodic maintenance
- No supplied details confirm water-tightness or plunge suitability
Verdict: Consider the muhub for mid-size freezer storage; do not rely on its dial as a way to set or maintain plunge-water temperature.
Upstreman 7.0 Cu. Ft.: Best for a Lockable Compact Freezer
The Upstreman is a 7-cubic-foot chest freezer with a lockable lid and a seven-level mechanical thermostat. Its listed temperature range is -18°F to 10°F. A lift-out wire basket helps organize small items, while the product description gives the unit’s exterior dimensions as 32.6 inches wide, 22.2 inches deep, and 33.5 inches high.
The size and lock may suit a household that needs a more compact freezer and wants to restrict access to its contents. The description also notes a pre-coated steel shell and an aluminum interior. Those construction details are presented for normal freezer use; they should not be read as confirmation that the appliance can safely hold bathwater.
Of the smaller choices, this model stands out for its stated dimensions and lock. However, the mechanical thermostat is intended to control the freezer, and the product details do not say that it controls water temperature. If you are exploring a DIY plunge, check both the manufacturer’s instructions and the requirements for a separate water vessel before making a purchase.
Pros:
- Lockable lid
- Listed exterior dimensions help with space planning
- Seven-level mechanical thermostat
- Removable basket for smaller stored items
Cons:
- Does not include confirmed plunge-water temperature control
- Not described as a water-tight or immersion-safe tub
Verdict: The Upstreman is a practical size-focused food freezer with a lock, but it should not be treated as a plunge-ready appliance.
TABU 12.0 Cu. Ft.: Best for More Storage in a Mid-Size Format
The TABU chest freezer offers 12 cubic feet of storage, more than the compact models but less than the 21-cubic-foot Hamilton Beach. The product lists its dimensions as 22 by 32 by 34 inches and describes a hinged lid that opens between 45 and 90 degrees. A removable basket and leveling legs round out its basic storage features.
A seven-level control is listed with a range of -7.6°F to 6.8°F. The product description also names an R600a compressor and says the unit operates at no more than 40 dB. These specifications relate to freezer operation. They do not establish that the unit can regulate bathing water or safely contain it.
The TABU may appeal to shoppers who want more food-storage space than a 6.7- or 7-cubic-foot model while avoiding the largest listed capacity. Its stated dimensions are useful for initial space planning, but they are not internal measurements. For a plunge conversion, you would still need to confirm that any separate water container fits and is properly supported, and that the manufacturer permits the intended arrangement.
Pros:
- 12 cu. ft. capacity offers substantial food-storage space
- Listed dimensions can help with placement planning
- Removable basket and leveling legs
- Seven-level temperature adjustment
Cons:
- Internal dimensions are not provided in the supplied details
- Not identified as a water-tight cold-plunge tub
Verdict: Pick the TABU if you need a larger general-purpose freezer, but choose a purpose-built plunge system if you want a product designed to hold and chill bathwater.
How to Choose a Chest Freezer for a Cold Plunge
Start with a Purpose-Built, Water-Tight Vessel
A chest freezer is designed to store frozen goods, not to act as a bathtub. The supplied descriptions do not confirm that these models are water-tight or built to handle the weight and pressure of bathwater. Water getting into appliance components can create a serious electrical hazard and may damage the freezer. Before considering any conversion, ask the manufacturer whether the intended use is allowed. A purpose-built plunge tub avoids this uncertainty.
Plan for Electrical Safety
Cold-plunge setups combine water, a powered appliance, and often a wet floor. Do not assume that a freezer’s ordinary household plug or a garage-ready label makes it safe around bathing water. Follow the manufacturer’s instructions, keep electrical connections protected from moisture, and consult a qualified electrician about appropriate protection and placement. Do not use a unit with damaged cords or electrical parts exposed to water.
Check the Actual Space and Dimensions
Capacity in cubic feet describes storage volume; it does not tell you whether a tub, liner, or person will fit. Check exterior dimensions for your room or garage, then ask for internal measurements if a separate container is part of your plan. Leave room for the lid to open, airflow around the appliance, and access for cleaning and maintenance.
Understand What the Temperature Control Measures
The listed controls on these products are for freezer or refrigerator operation. The descriptions do not say they sense water temperature or maintain a chosen plunge temperature. A freezer setting is not the same as a water-temperature setting. If your goal is controlled, repeatable water cooling, look for a purpose-built system with controls designed for water.
Choose Capacity for Your Real Use
For ordinary food storage, match capacity to the space you have and what you plan to store. The VEVOR and Upstreman models are the smallest listed; the muhub offers 10 cu. ft.; the TABU offers 12 cu. ft.; and the Hamilton Beach offers 21 cu. ft. These figures do not show usable plunge volume, so do not use them alone to estimate how much water a conversion could hold.
Account for Cleaning and Defrosting
Several models list manual defrost, while the Hamilton Beach description highlights an exterior defrost drain. A DIY plunge system also needs a safe way to drain and clean the water-holding vessel. Confirm the appliance’s maintenance instructions and do not assume a food-storage drain or basket is designed for plunge use.
Compare a Freezer Conversion with a Dedicated Plunge
A freezer may cost less upfront than a complete cold-plunge system, but the product data here does not include a water-tight tub, water-temperature controls, or confirmation of safe conversion. A dedicated plunge tub and chiller are made for that job and can reduce guesswork. Compare the full setup—not just the appliance—including the vessel, temperature control, electrical work, water care, and ongoing maintenance.
Frequently Asked Questions
Can I fill one of these chest freezers directly with water?
The supplied product information does not say that any of these freezers are water-tight or designed to hold bathwater. Do not fill one directly unless the manufacturer confirms that use and provides safe instructions. A separate, purpose-built water vessel is a safer direction to investigate.
Will a freezer thermostat control the temperature of plunge water?
These products list controls for freezer or refrigerator operation, not water-temperature control. The descriptions do not confirm that the thermostat measures water temperature. Use a system designed to control plunge water if you need a specific water temperature.
Which model has the most storage capacity?
The Hamilton Beach HBFRF2129 is the largest listed option at 21 cu. ft. That figure refers to freezer storage capacity and does not confirm how much water a plunge setup could hold.
Which option is smallest by listed capacity?
The VEVOR has the smallest listed capacity at 6.7 cu. ft., followed by the Upstreman at 7 cu. ft. Capacity alone does not confirm that either model will fit a particular room or DIY container, so check dimensions before ordering.
Is a garage-ready freezer automatically safe for a cold plunge?
No. Garage-ready describes operation in certain environmental conditions, not safe use as a bathing vessel. The VEVOR description lists an ambient operating range, but that does not confirm water-tightness or electrical safety around bathwater.
What should I buy for a reliable cold plunge?
Look for a purpose-built cold-plunge tub and a compatible water-cooling system with clear installation and electrical safety instructions. If you are considering a DIY conversion, get explicit manufacturer guidance and professional advice before exposing a freezer to water or placing electrical equipment near a plunge.
Final Recommendation
For freezer storage, the Hamilton Beach offers the most capacity, the VEVOR adds electronic controls in a compact format, and the TABU provides a middle ground with 12 cu. ft. But none of the supplied descriptions confirms that these appliances are safe, water-tight cold-plunge tubs. If your main goal is cold immersion, choose a purpose-built plunge system; consider these chest freezers only for their intended food-storage use unless a manufacturer-approved conversion plan says otherwise.
