Built this ice bath 2 years ago. Has been great I just don’t use it anymore. Never finished painting it, functionality is great can get down to 30 degrees pretty easily. Everything plugs into a regular outlet. Has in line filter. 100 gallon, has a drain that you can hook up to a hose to drain, spray foam for insulation. Put close to 1000 if not more into it. Let me know if you have questions. Or best offer.
