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.
A leaking tank may require environmental remediation of the surrounding soil and any nearby water sources if the tank held fuel. If the tank was damaged due to age, soil conditions or severe weather, it may cost more to remove. Remediation may cost $10,000 or more depending on the scope of the pollution.
