Frequently asked questions

Does a hot tub need a permit?

The spa itself is often exempt, but the dedicated circuit, disconnect and bonding are electrical work that most jurisdictions permit and inspect. Barrier or fencing rules may also apply.

What electrical service does a hot tub need?

Most full-size spas need a dedicated 240-volt, 50-amp GFCI-protected circuit. Plug-in 120-volt models avoid that work but heat far more slowly.

How long does hot tub installation take?

1-3 days of work, 2-5 weeks including permitting and delivery. Permit review and inspection scheduling are usually the largest source of variation.

What changes the price the most?

The largest cost drivers are spa size, shell quality and jet count; concrete pad, deck reinforcement or gravel base; distance from the panel and the amperage of the new circuit.
