Hot tub statistics
Short answer
About 8.84 million US homes had a hot tub in 2020, the Energy Information Administration found, and the Department of Energy estimated that about 230,000 electric spas were shipped in 2019. Leslie's sizes the US market for new spas at about $1.6 billion.
How many hot tubs are sold each year?
About 230,000 electric spas in 2019, the latest public estimate we could find, made by the Department of Energy from P.K. Data market figures. We found no newer free yearly count, and the big public companies report pools and spas together.
Masco sells Hot Spring, Caldera and Endless Pools inside its plumbing products segment and gives no sales figure for spas alone (10-K, fiscal 2025). Pool Corporation, the pool supply distributor, says its industry serves more than 14.0 million pools and hot tubs in the US, without splitting the two (10-K, fiscal 2025).
