“This model is the perfect spa when downsizing. This is our 5th spa, second Caldera, and is so far the easiest to maintain. The salt water system is so efficient we hardly use any additional chemicals. The size is easy for getting in and out of as we age.”

Hot Tub Essentials.


Each hot tub comes equipped with a custom-built cover, made to the exact measurements of your spa. This ensures a tight seal for optimum energy efficiency. The durable, marine-grade vinyl cover includes child safety locks and is UL listed in compliance with ASTM standards.

Cover Lifters

A hot tub cover lifter is an essential spa accessory that protects your spa, the cover, and your investment. Designed to allow one person to effortlessly remove and replace the cover, a lifter makes it easy for you to be in your spa in seconds.


We offer color-matched hot tub steps to help you enter and exit your spa with ease.
