The verdict

The Cold Plunge Pro is a 150-gallon stainless tub with a chiller that Sun Home says sets as low as 28°F. It plugs into a standard outlet on its own 15 A GFCI circuit and fills with a hose. The catch is a one-year warranty on a $14,599 tub.

The trade-off

At $14,599, you get one year of coverage, and labor and shipping are covered only for the first 90 days.

A GOOD FIT FOR

You want very cold plunges in a stainless hard-shell tub without plumbing, and you can give it a dedicated 15 A GFCI circuit.

You want very cold water, with a set point as low as 28°F
You want a stainless basin and a hard insulated shell instead of an inflatable tub
A spot with a dedicated 15 A GFCI circuit and about 9.5 × 5 ft of space
You'd rather skip plumbing and fill it with a hose

THINK TWICE IF

Warm soaks, since Sun Home lists no heating and the set range tops out at 70°F
Outdoor use through a freezing winter
A floor or deck that can't carry 400 lb of tub plus about 1,250 lb of water
You might change your mind, since an opened tub can't be returned and an unopened one costs 25% plus shipping
You want more than one year of warranty coverage

Before you buy

InstallationThere's no plumbing: you fill it with a hose

There's no plumbing: you fill it with a hose. It's rated 120 V and 12 A. The 8 ft cord can't be removed and plugs into a standard NEMA 5-15 outlet. That outlet must sit on a dedicated 15 A GFCI circuit, and Sun Home says no hardwiring is needed. The spec sheet asks for 3 ft of clearance at the vent end and 1 ft on each side. The head end can sit against a wall, and the whole setup needs about 9.5 × 5 ft. It's rated for indoor and outdoor use on a surface that can carry the filled tub. Sun Home says not to run it outdoors below freezing or leave it out through freezing weather. The first cool-down takes several hours, and the lid shortens it.

WarrantySun Home gives the Cold Plunge Pro a 1-year residential limited warranty…

Sun Home gives the Cold Plunge Pro a 1-year residential limited warranty against manufacturing defects. It covers the original buyer only. It starts at purchase or delivery, whichever is later, as long as delivery is within six months of purchase. Labor and shipping are covered for the first 90 days from delivery. After that, you pay both, and Sun Home chooses whether to repair or replace. Wear and tear, abuse, improper installation, electrical problems and use outside the published guidelines aren't covered. The product page shows a "1+ Year Warranty" badge and a site-wide "Limited Lifetime Warranty On Most Models" banner. That lifetime coverage is for cabinetry and heaters on some saunas, and the warranty page lists the Pro at one year. Extended warranties are sold separately, but no price is given. Commercial buyers get separate terms at the point of sale.

ReturnsYou can return it within 30 days of delivery only if it's unused…

You can return it within 30 days of delivery only if it's unused and still in its original, unopened packaging. Sun Home won't take back an uncrated, assembled or used cold plunge. It keeps a 25% restocking fee and charges shipping both ways, even on a free-shipping order. Returns need approval through Sun Home's returns portal first. Refunds are issued within 21 days of receiving the return, after inspection. Every cancellation costs 3% per product, even within 24 hours of ordering. After 24 hours, a 25% restocking fee is added, and you may pay roundtrip shipping. On a $14,599 tub, the restocking fee alone is $3,649.75.

Replacement parts & cost assumptions

Recorded recurring parts and refills:

Cold Plunge Filter 3-pack (10 × 2.5 in, 20-micron, SKU FILTER25): $49 every 1.4 months. One $49 pack holds three filters, about $16.33 each. Sun Home's store and filter page say to change the filter every 2 to 4 weeks, depending on use and water conditions. At every 2 weeks, a pack lasts about 6 weeks. The product page says at least monthly, or every 2 weeks with daily use. The filter page lists the Pro as compatible but not the Pro Apex.

Purchase is the $14,599 regular price for the base Cold Plunge Pro, SKU PLUNGEPROS, on Oct 13, 2026. There was no sale, and shipping was listed as free.
Installation is unknown. The tub needs a dedicated 15 A GFCI circuit, and Sun Home doesn't price adding one. It also doesn't say whether delivery includes placement.
Filters are $49 for a 3-pack, or about $16.33 each. Sun Home says to change them every 2 to 4 weeks. The estimate uses every 2 weeks: 26 filters, or $49 × 26 ÷ 3 = $424.67 a year. At every 4 weeks, it's 13 filters and about $212.33.
Energy isn't estimated. Sun Home gives no average draw or daily run time. The 12 A, 120 V rating caps draw at roughly 1,440 W.
Other yearly costs are left unknown. The app is listed without a fee, but Sun Home doesn't say it's free.

Evidence & sources.

Do cold plunges work? Our evidence review grades the research as Mixed. That grade is about the claim, not about this product.

Manufacturer claimPrice, set range, cool-down time, chiller, electrical needs, dimensions, weight, water care, included items, filter price, and warranty and return terms all come from Sun Home. The sources are its product page, store listing, September 2026 spec sheet, filter page, warranty FAQ and warranty page.^1–6 None of it is independent testing of cooling speed, temperature holding, water quality or durability.
Manufacturer claimThe store description quotes Business Insider and Forbes praising the tub.² Sun Home picked these quotes. The original articles weren't reviewed, so they don't count as independent evidence here.
Manufacturer claimSun Home names no electrical safety listing (ETL, UL or CSA), regulatory clearance or independent test for the tub or chiller on the product page or spec sheet.^{1, 3} A chilled tub is consumer equipment, not a regulated medical device. A listing missing from these pages doesn't prove none exists. The owner's manual, certifier databases and studies of cold-water immersion weren't reviewed.
