What a filled PureSpa Plus Bubble Massage (85in) weighs
Once running, this spa bears down with about 3,604 lb. The arithmetic: 2,419 lb of water plus 1,110 lb of occupants at capacity. Over 39.4 square feet, call it 91 psf. Work out any tub on the filled weight calculator.
Powering this spa: the estimate
Idle but hot, 290 gallons loses heat worth about 7.0 kWh every day at a 102 F set point in 50 F air. The monthly damage: near $36 at $0.17/kWh, anywhere from $26 to $54 depending where you live. Model your own rate and climate on the running cost calculator.
