The details
Keeping it hot: standby power and cost2
Standby is what a tub draws to hold its heat with the cover on and nobody in it. California tests it for every spa sold in the state. At the US average 18.19¢ per kWh (January to July 2026), the middle Cal Spas model costs about $29 a month to keep hot and the middle Master Spas about $25 a month. In watts: 218 W (39 filings) and 191.5 W (28). Your bill also depends on your climate, how hot you keep it and how often the cover is off.
| Seats | Cal Spas | Master Spas |
|---|---|---|
| 3 | 157 W | 148 W |
| 4 | 157 W | 169.5 W |
| 5 | 242 W | 190.5 W |
