So how much does a float tank cost? Float tank prices vary widely depending on the size and the features of the float tank or pod you want to buy. Expect to spend anywhere from $12,000 to $40,000 to buy each commercial-grade float tank needed in your spa.
Doing some research for a new tank was sticker shock over $1000.00 and I really didn't want to use acids in a tank this old. Buying a used tank was dealing with maybe more problems. I came across an electrolysis method the I was willing to try before going the acid route.
