| Exact variant | Cold Plunge Pro (base model, SKU PLUNGEPROS): 150-gallon hard-shell tub with a 316 stainless basin, not the Pro Apex or Pro Titan | Horizontal (2-Person), SKU POLAR623: inflatable lie-down tub with a 1 HP chiller that cools and heats |
| Dimensions | The assembled tub measures 78.7 × 33.5 × 34.2 in (length, width, height). Inside, the spec sheet gives 47.4 × 28.7 in, with 27.5 in of depth. It holds 150 gallons and weighs 400 lb dry. Sun Home doesn't give a filled weight, but 150 gallons of water alone weighs about 1,250 lb. It ships in an 84 × 37 × 42 in crate that weighs 636 lb. The spec card rates it for one person. | The assembled tub measures 77.2 in long, 27.6 in wide and 24.4 in high. The manual and store description give the outer size as 6.4 × 2.3 × 2.1 ft. The store description puts the inside at 69 × 19.5 in, and the spec sheet at 69.3 × 19.7 in. The chiller is a separate box, 21.2 × 15.7 × 21.7 in. Empty, the tub weighs 15.5 lb and the chiller 88 lb. The spec card, spec sheet and manual list 128 gallons (485 L in the manual). The store description says 80 to 90 gallons instead. Sun Home doesn't explain the gap. The manual's fill line is 8 in below the top. Sun Home doesn't give a filled weight. |
| Installation | 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. | No plumbing is needed, Sun Home says. The tub inflates to 10 to 12 PSI with the included air pump, and the chiller connects with the included inlet and outlet hoses. The chiller plugs into a standard NEMA 5-15 outlet. That outlet must sit on a dedicated 15 A GFCI circuit. The manual says a licensed electrician should do all electrical work, and the wiring must follow local code. It also asks for a flat surface that can support 3,000 lb. Keep the chiller fan 3 ft from the tub and from walls. Keep the plunge at least 5 ft from other appliances. Leave 36 in clear in front of and behind the tub. Let the chiller stand upright and unplugged for 4 hours before first use. Sun Home rates the tub for indoor and outdoor use, but the chiller needs ambient air above 40°F to run. |
| Materials | The basin is 316-grade stainless steel inside a hard shell with injected insulation. Sun Home calls it marine-grade construction. An insulated lid, a headrest and stair mats are included. It also has a touchscreen panel and interior lights with a color remote. Sun Home doesn't name the shell material or the insulation type on the pages reviewed. | Sun Home describes a puncture-resistant inflatable tub with an insulated cover and lid. It doesn't name the tub's fabric or construction, or the cover's material. The box also includes an air pump, inlet and outlet hoses with gaskets, a metal inlet screen, a spare 20-micron paper filter, a filter wrench, a repair kit and a carrying case. |
| 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. | Sun Home gives the Cold Plunge a 1-year residential limited warranty against manufacturing defects.
