How Much Does It Cost to Run a Hot Tub in Canada? (2026)
A hot tub heater runs several hours a day to maintain temperature, and the circulation pump runs much longer. Inflatable hot tubs are the most expensive to run because they lose heat quickly through thin walls.
A typical hot tub (3,000 W) costs C$0.42 per hour, or about C$50.40 per month at 4 hours a day in Canada. Expensive to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 1,500 W | C$0.21 | C$0.84 | C$25.20 | C$306.60 |
| Typical 3,000 W | C$0.42 | C$1.68 | C$50.40 | C$613.20 |
| High 6,000 W | C$0.84 | C$3.36 | C$100.80 | C$1,226 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 4 h/day ≈ 4,380 kWh per year.
One hour of a hot tub (3.0 kWh) is the same electricity as
- 17km in an electric car
- 30hours of TV
- 67hours of a laptop
- 333hours of an LED bulb
In Canada, with electricity at 14.0¢ per kWh (source: Canada Energy Regulator 2026 market snapshot, 2026-06), a typical hot tub costs C$0.42 per hour and about C$613.20 per year at 4 hours a day. Each C$1.00 of electricity buys roughly 2.4 hours of use.
How to lower the cost of running a hot tub
- Keep the insulated cover on whenever the tub is not in use. Most heat escapes through the water surface.
- Lower the set temperature by a few degrees between uses.
- Place the tub out of the wind or add a windbreak.
- Inflatable tubs can use two to three times the electricity of a hard-shell model.
In standby it draws about 100 W, which adds roughly 876 kWh (C$122.64) per year if it is never unplugged.
Is an efficient hot tub worth it?
Inflatable hot tub outdoors, about 12 kWh a day: about 4,380 kWh a year. Insulated hard-shell tub with a thermal cover, about 5 kWh a day: about 1,825 kWh. The difference is worth C$357.70 a year in Canada.
- Replacing one that still works pays back in 14.0 years.
- When yours needs replacing anyway, the extra cost of the efficient model pays back in 11.2 years.
Usage assumed: kept hot all year. Typical prices: C$5,000 for the efficient model, C$4,000 more than a basic one. Work it out with your own prices
Frequently asked questions
How much does a hot tub add to the electricity bill?
Commonly 3 to 8 kWh a day in mild weather and much more in winter, so it can be one of the largest household loads.
Is it cheaper to keep a hot tub on all the time?
For regular use, yes. Reheating from cold uses more than maintaining temperature under a good cover.
How much does an inflatable hot tub cost to run?
Often 8 to 15 kWh a day because of poor insulation, especially outdoors in cool weather.
