XR Cryo Plunge Acrylic Tub Review

The XR Cryo Plunge Acrylic Tub is a freestanding acrylic cold plunge tub sold with a chiller that cools, heats, filters and sanitizes the water. Cryo Innovations LLC of Newport Beach, California sells it through its XR Cryo Plunge store with its 2025 Chiller/Heater included. The standard tub costs $5,500 and the extra-long one $6,500, next to crossed-out prices of $6,900 to $7,400; a water catcher basin adds $150 to the standard tub and $650 to the extra-long one. This review quotes what you would pay.

The store sizes the tub by the user's height. The standard tub, 67 inches long, 32 wide and 24 high, is for people under 5'9"; the extra-long tub, 73 by 33 by 27 inches, is for people from 5'9" to 7'. The water catcher is a 49.5 by 22 inch step, 3.25 inches high, that sits beside the tub. The store says installation takes two steps and that the tub can go indoors or outdoors. It doesn't give the water volume, so ask how much water and floor load to plan for.

The 2025 Chiller/Heater stands beside the tub on wheels and connects to it with hoses. The store describes a top-mounted filter that takes seconds to change, chilling and heating in one unit, automatic shutdown and system alerts, but it publishes no power or capacity figures for it; an earlier version of this product page listed 110 V and 3,050 W (1 HP) of cooling capacity. The XR user manual on the store's 2025 instructions page (version 6, May 2024) gives a settable water temperature of 3 to 42 °C (37 to 107 °F) and describes a self-priming circulation pump, an external cartridge filter and a built-in ozone sanitizer. The store quotes 38 °F as the lowest.

The chiller has a touch panel, and the Tuya Smart or Smart Life app controls it from an iOS or Android phone over 2.4 GHz Wi-Fi only. You can set the temperature, switch between °C and °F, set how long the ozone runs (up to 5 minutes), see the water flow, lock the screen, set an on/off timer and let it restart on its own after a power cut. The tub has an underwater LED light: its cord plugs into an outlet, and a button on the side of the tub cycles through the colors.

Cryo Innovations' residential chemical sheet uses non-chlorine Sirona products, with separate doses for its standard and XL tubs: pH up, oxidizer and sanitizer when you fill it, then oxidizer every week, a wipe of the water line and jets, hair cleared from the drain strainers and a check with test strips. Don't fill it with softened water. Earlier store pages said a starter kit of Sirona Sanitizer, Oxidizer, pH Up, pH Down and test strips comes with it, and the brand's FAQ said to change the water every 2 to 4 weeks depending on use.

The manual asks for at least 50 cm (about 20 inches) of free space around the chiller, an air temperature between 1 and 45 °C (34–113 °F) while it runs, and the filter element always in place. The chemical sheet warns that a chiller running without water flow can freeze and be damaged, and says to empty the tub, filter and chiller if the system stops filtering or is switched off. The manual lists CE certification; it doesn't mention a UL or ETL listing.

The store's shipping policy says orders usually ship in 4 to 6 weeks, depending on inventory, the quantity ordered and your location, and a sales rep gives you the date; shipping is calculated at checkout. Returns must be requested in writing within 30 days of delivery and need a Return Authorization number, and the equipment must come back undamaged. You pay both the original and the return shipping, which come out of your refund, and the store's refund policy also says sale items can't be returned, while every XR product is shown at a sale price. The current page doesn't state a warranty; earlier store pages and current dealer listings give one year, with 2- and 3-year options for sale.

Within the range, the inflatable tub costs $4,199 with a cooling-only Super Chiller and packs down when you don't need it, while the WINDOW ($8,500) is an acrylic tub with a see-through front panel, a headrest and three months of chemicals. Neither the manual nor the store's pages say who should avoid cold-water immersion or for how long, so ask your doctor first if you have a health condition.
