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 Caldera model costs about $26 a month to keep hot and the middle Sundance about $21 a month. In watts: 199.5 W (18 filings) and 157 W (19). Your bill also depends on your climate, how hot you keep it and how often the cover is off.
| Seats | Caldera | Sundance |
|---|---|---|
| 3 | 152 W | 123 W |
| 5 | 195 W | 136 W |
| 6 | 198 W | 160 W |
| 7 | 214 W | 164 W |
| 8 | 307 W | 193 W |

What to ask in the showroom1
- Manifold-fed jets: Caldera doesn't publish it. Ask: “Does each jet here get its own hose from a manifold, or are they chained?”
