How Much Does a Hot Tub Cost to Own?
The purchase price is just the beginning. A $6,000 hot tub can easily cost $2,000-4,000 per year to run, meaning the 5-year ownership cost approaches $16,000-26,000 total.
Breaking Down the Costs
Electricity is the biggest ongoing cost, typically $600-1,200/year. Chemicals run $200-600/year for sanitizers, pH balancers, and shock treatment. Filters need replacing every 1-2 years ($50-150). Water changes every 3-4 months cost $20-50 in water and chemicals each.
Estimates are approximate. Consult local dealers for region-specific pricing.
