Which suits whom?

Cal Spas, if you want

  • One maker for the whole backyard
  • A lounger (32 models against 15)
  • A tub that plugs into a regular outlet (5 models)

Bullfrog, if you want

  • Swappable JetPak massage seats

Fit decides more than any figure here. Sit in both in the seat you would use most (dry is fine), feel the jets on a running display tub with the back of your hand, and read both warranty cards before you sign.

What’s a good deal on either?

Pick a brand. We send you the price range, then connect you with one dealer near you for it.

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 Bullfrog about $27 a month. In watts: 218 W (39 filings) and 207 W (23). Your bill also depends on your climate, how hot you keep it and how often the cover is off.
