Why Most Cross-Fitters Are Sabotaging Their Own Recovery Without Even Knowing It
The root cause holding athletes back isn’t just the intensity of their workouts — it’s inefficient recovery. Traditional ice baths take forever to prepare, are a hassle to maintain, and most tubs only do cold or hot therapy — forcing athletes to compromise or skip key recovery sessions. This leads to prolonged soreness, higher injury risk, and stalled progress.

How DiveTubs’ Fast-Chill + Rapid-Heat System Crushes Recovery Like No Other Tub
DiveTubs’ patented fast-chill and rapid-heat technology is the only system on the market that delivers both cold plunges down to 37°F and hot soaks up to 107°F—within minutes—without any plumbing or complicated setup.

Frequently Asked Questions
What’s the difference between an ice bath and a cold plunge?
A cold plunge uses a built-in chiller and filtration so you don’t need bags of ice; an ice bath requires manually adding ice. Plunge units maintain temp and clean the water automatically. Ours offers both automatic cooling and automatic hot therapy as well.
What temperature should I use?
Most athletes use ~37°F–59°F for cold plunges; beginners start warmer and work down. For hot soaks, the tub goes up to 107°F. (DiveTubs supports 37°F–107°F)
How long should I stay in a cold plunge?
Short sessions are best — 30 seconds to ~5–10 minutes depending on experience and temperature. Start short and build up.
Is it safe? Any medical warnings?
Cold plunges are generally safe for healthy adults, but consult your doctor if you have heart disease, high blood pressure, pregnancy, or other serious conditions. Stop immediately if you feel dizzy or numb.
How long does it take to cool or heat?
Times vary by ambient temp and unit power; high-end plunge systems are engineered to chill/heat in minutes (fast-chill/rapid-heat tech cuts that time significantly). Expect faster results than manual ice baths.
Do I need plumbing or special electrical work?
DiveTubs is plug-and-play and require standard household power — no plumbing.
How do I keep the water clean?
Use the tub’s filtration + ozone (or recommended sanitizer) - already built-in.
How much space do I need?
Measure your intended spot and allow clearance to access the tub and for delivery. DiveTubs fits users up to 6′9″ comfortably — pick a spot that allows safe entry/exit.
Can I use it indoors and outdoors?
Many athletes use daily or several times per week, depending on training load and goals. Use shorter sessions more frequently when training heavily.
How often should I use it?
Yes of course!
What about returns/warranty?
We offer a 30-day money-back guarantee and a 5-year warranty - that's how confident we are!
I used to limp for two days after heavy deadlifts. Since using DiveTub consistently, I recover so much faster. I can actually walk normally the next morning.
I always thought ice baths were a fad. After using this, I get why serious athletes swear by it. My soreness is cut in half.
I hit brutal metcons almost daily. Hopping in the DiveTub right after resets me. Feels like hitting a restart button for my body.
CrossFit wrecked my shoulders for years. The hot/cold cycles in this tub have been a lifesaver. Less inflammation and more mobility.
Didn’t expect this, but since I started using the tub, my sleep has improved big time. Muscle recovery + better rest = PRs are coming faster.
