This is the complete RevX cold plunge system: the acrylic X Tub paired with the LUX high-performance chiller and filtration unit. At over 34 inches tall it is the deepest acrylic tub on the market, which means full above-the-shoulder submersion while you stay seated upright rather than curled up.

Why the depth matters
Most acrylic plunge tubs force you to either lie back or tuck your knees to get your shoulders under. The X Tub's 34-inch depth lets you sit upright with your shoulders submerged, which is a more sustainable position if you are working up to longer holds. The three-inch foam walls hold the cold, so the chiller cycles less and the water stays where you set it.
The jets
Still water forms a slightly warmer layer against your skin. The adjustable jets keep the water moving, so the cold stays consistent across the session rather than easing off as you sit. You can dial them back if you want a gentler entry.
Cold and hot in one unit
The LUX chiller runs from 34°F up to 104°F, so the same system can be used for warm soaking. If you are pairing this with a sauna, that flexibility is what makes contrast sessions practical without a second piece of equipment. See our contrast therapy guide.
What to expect
Cold water immersion produces a strong, short-lived arousal response, and people commonly describe feeling alert and clear-headed afterward. What that reflects at the level of brain chemistry is not settled, and claims naming specific neurotransmitters are stated with more confidence than the evidence supports. Start with short holds and warmer temperatures and build from there. Our cold plunge starter guide covers a sensible first month.
A cold plunge is not a treatment for any medical condition and is not a substitute for medical care.
Before you buy
Check your space for the tub footprint plus clearance around the chiller cabinet for airflow, and confirm you have an appropriate outlet nearby. Our cold plunge setup guide walks through placement, drainage, and power.

FAQ
How cold does it actually get? The LUX chiller cools to 34°F, which is just above freezing. Most people settle somewhere well above that once they find their range.
Can I use it as a warm tub? Yes. The same unit heats to 104°F.
Do I need plumbing? No. It is a self-contained system with integrated filtration. You fill it, and the chiller and filter handle the rest.
How deep is it really? Over 34 inches, which is enough to submerge to the shoulders while seated upright rather than reclining.
Who should avoid cold plunging? Anyone who is pregnant, has a cardiovascular or circulatory condition, has low or unstable blood pressure, or takes medication affecting heart rate or hydration should speak with a clinician first. See our cold plunge safety guidelines.
Cold water immersion is intended for general wellness and recovery. It is not a treatment for any medical condition. If you are pregnant, have a heart or circulatory condition, or another health concern, talk with your doctor before use.
