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.
An important consideration for fuel tank installation prices is whether the tank is aboveground or underground. To remove and replace an aboveground tank, plan on paying approximately $1,500 to $2,500. For an underground tank, the total cost might be twice as expensive, or $3,000 to $5,000 and up. Soil testing for contamination will run you an additional $300 to $600.
