A complete cold plunge system built around a purpose-made acrylic tub and a separate high-output chiller and filtration cabinet. It arrives ready to run: fill it from a garden hose, plug it in, and set a temperature. No plumbing connection of any kind.
A tub built for plunging, not a bath being used as one
The X Tub stands over 34 inches tall, deep enough to sit upright with your shoulders under the water instead of lying back or folding up. The acrylic shell is wrapped in three-inch foam-insulated walls, which hold cold in and keep ambient heat out — so the chiller runs less and the water is ready when you are. Adjustable water-flow jets keep the water moving and break up the warm thermal layer that forms against your skin, so the plunge stays consistent instead of easing off as you sit still.
Three parts, on purpose
RevX separates the chiller from the circulation, filtration and sanitation gear rather than packing everything into one housing. The chiller does one job — temperature — while the pump, filter, UV and ozone live in their own cabinet. The result is larger components than an integrated unit can fit, independent serviceability, and fewer things inside the chiller that can fail. The design is patent-pending.
The chiller
1.5 HP, running on Panasonic compressors, cooling to 34°F or heating to 104°F — cold enough for a genuine plunge and warm enough for a soak, so the system works year-round. Wi-Fi enabled. Rated IP55, so it stands up to dust and water jets outdoors.
The filtration cabinet
A high-flow pump turns the full water volume over four times an hour, through a 20-micron, 10-inch cartridge filter — a standard size, so replacements are inexpensive and easy to find. UV and ozone sanitation treat the circulating water, so the system runs without added chlorine or bromine.

Installation and siting
Setup takes about an hour including filling, and RevX provides step-by-step installation video. Two things to plan before delivery:
-
Power. Four separate 110 V outlets — one for the chiller, three for the filtration system — with a combined draw up to 14 A. RevX recommends a dedicated 15 A circuit; ask your electrician whether a dedicated 20 A circuit is the better call for continuous running. Use GFCI protection outdoors.
-
Clearance. The chiller needs at least 12 inches at the sides and rear and 24 inches at the front to move air. Operating it in a tighter space voids the warranty.
Site the tub on a flat, level surface that can carry the filled weight, and keep the chiller and filtration cabinet level and clear of standing water.
Warranty — register within 30 days
One year against defects in materials and workmanship, to the original purchaser only, non-transferable, on units bought from RevX or an authorized reseller.
Coverage is conditional on registering the product within 30 days of delivery, which requires your order number and a video of at least 30 seconds showing the system installed to RevX's specification. If you don't register in that window, the warranty is void — so register before your first plunge. Excluded: modification, misuse, improper maintenance including missed filter changes, running without proper water flow, exceeding the rated water volume, insufficient chiller clearance, submersion beyond the IP55 rating, shipping damage and normal wear. On an approved claim the customer covers freight to RevX; RevX covers the return leg within the continental US.
Who it's for
People who plunge regularly and want equipment they can service rather than replace — serious home users, and recovery rooms and studios that need something to survive daily use. The heating side means one system covers cold plunges in summer and warm soaks in winter.
Before you use it
Cold water immersion is not for everyone, and this system reaches 34°F — colder than most. Sudden immersion in cold water triggers an involuntary gasp and a sharp rise in heart rate and blood pressure, and the effect is stronger the colder the water. Talk to your doctor before using a cold plunge if you have a heart condition, high blood pressure, circulatory problems, or are pregnant. Never plunge alone, enter gradually using the steps, keep sessions short, and get out immediately if you feel dizzy, numb or short of breath. Keep the insulated cover on and secured when the tub is unattended, particularly where children have access.
