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.
1 According to estimates from the EPA (that are about 10 years old), the septic tank installation cost, including the tank and drain field, can cost anywhere between $1,900 and $9,000 with an average of $4,000 for a standard system in an area with good soil.
