Spas & Hot Tubs in Arizona

Spas and hot tubs are often kept warmer than the pool they are attached to, so heater choice and controls matter. These businesses hold an Arizona ROC B-10 Pre-Manufactured Spas and Hot Tubs license or mention spas or hot tubs in their business name.

Why choose this

  • Familiar with spa equipment, controls and heaters.
  • Can often handle both a pool and an attached spa.
  • Arizona ROC licenses B-10 Pre-Manufactured Spas and Hot Tubs contractors separately from pool builders.

Things to consider

  • Some spa businesses mainly sell portable hot tubs; ask whether they do built-in installs.
  • An attached spa may need more heat than the pool alone; make sure the heater suits both.
  • Electrical work for portable spas may need a licensed electrician.

Questions to ask

  • The contractor's Arizona ROC license number and class, so you can confirm it on the ROC contractor search.
  • Who pulls the permit (and any separate electrical, plumbing or gas permit) and whether permit fees are included.
  • The heater make, model and output, and how they sized it for your pool. Ask them to show the calculation.
  • Warranty terms: manufacturer warranty on the equipment and the contractor's own warranty on labor.
  • Whether the heater will serve the pool, the spa or both, and how quickly it heats the spa.
  • Controls and automation for switching between pool and spa.

Frequently asked questions

Can solar heat my spa?

The U.S. Department of Energy notes that spa owners may use a solar system to heat both the pool and the spa, but usually use a backup heater to get the spa to a higher temperature.

Who can install a heater for a built-in spa?

An Arizona ROC-licensed contractor whose class fits the job, such as a swimming pool contractor for a built-in spa. Confirm the license and class on the ROC contractor search before signing, and ask whether they install the heater type you want.
