How much does it cost to run a swim spa?
Asked by Hot Tub Hunt Pros•August 12, 2026
What should I expect on my power bill?
Pro Answer
Monthly electricity for a swim spa usually lands between $50 and $150, with cold-climate winter months at the top of that range.
The factors that move the number most:
- Set temperature: Every degree costs money. Holding 86F for swimming is significantly cheaper than holding 100F.
- Insulation: Full-foam and multi-layer insulated cabinets hold heat far better than partially insulated ones. This is where premium models earn back part of their price in cold climates.
- Cover quality and fit: Most heat loss is through the surface. A sagging, waterlogged cover can double heating cost.
- Pump runtime: Circulation and filtration schedules matter; low-amp circulation pumps use much less than the swim jet pumps.
If you plan to swim year-round in a northern climate, prioritize insulation and cover specifications over jet count.
