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.

Few, if any in larger or smaller sizes. About $10 exchange. When you buy an empty tank take to keg place (empty), give them $10 +/- (depends on place) and get a full tank in exchange.
