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 Hot Spring model costs about $23 a month to keep hot and the middle Bullfrog about $27 a month. In watts: 175.5 W (24 filings) and 207 W (23). Your bill also depends on your climate, how hot you keep it and how often the cover is off.
| Seats | Hot Spring | Bullfrog |
|---|---|---|
| 3 | 146 W | 157.5 W |
| 4 | 159 W | 158 W |
| 5 | 178 W | 166 W |
| 6 | 196 W | 179.5 W |
| 7 | 211 W | 208.5 W |

What to ask in the showroom2
- Clamped plumbing: neither brand publishes it. Ask: “Are the hoses on this model clamped at the barbs, or just glued?”
- Manifold-fed jets: Hot Spring doesn't publish it. Ask: “Does each jet here get its own hose from a manifold, or are they chained?”
