Put every hot tub quote on equal terms.
Compare purchase price, seats, electrical supply, warranty and estimated electricity costs without hiding the assumptions behind a single score.
Use the same assumptions
Compare up to three quotes
Replace every example with figures from written quotes and published test information.
Ask what sits behind the energy number
A daily kWh figure is only comparable when the testing conditions are clear. Ask about ambient temperature, water temperature, filtration, cover use, bathing and whether the figure comes from the exact model. Your measured use can differ materially.
Price is more than the shell
BISHTA highlights base preparation, electrical supply, transport, water treatment and maintenance as costs buyers should consider. Check whether steps, cover lifter, commissioning, delivery and water-care training are included in each written quote. Read BISHTA’s official cost guidance .
