Frequently Asked Questions about Cold Plunge Tub

Not often. Just replace filters and add weekly sanitation so your water can stay crystal-clear for months:

  • Light use: Every 6 months
  • Heavy use (daily/multiple users): Every 3 months
  • Replace the 20-micron filter every 2–4 weeks
  • Clean the built-in strainer monthly
  • Clean the dust-proof net every 3 months
  • Add a non-chlorine sanitizer weekly

Even with heavy use (2 filters used per month), total water care is just $45.42/month—including filters and full sanitation. No ice runs. No spa bills. Just crystal-clear water, always ready.

We’ve fit a 250lb+ person before, you just need to be careful of the water level check out some photos here.

We’ve also had multiple >6ft 5” users comfortably fit and head dunk without their knees popping out or water spilling over the edge.

"Best part is that being 6’- 4” I STILL totally fit in the tub, all the way submerged up to my chin, without needing to do a yoga pose just to fit. I can comfortably sit, fully under the water, every time AND I can grab the top rails to pull myself up when getting out (unlike a normal tub)." - Ian Rice.
  • ~65 dB during cooling (like a quiet AC)
  • Virtually silent during idle/circulation

Nope. It runs on a standard 120V household outlet (15A grounded circuit), it’s recommended to have a dedicated circuit for it i.e. no other large appliances on the same circuit.
