Spend less time caring for water and more time creating memories


Enjoy peace of mind knowing the optional ACE Salt Water System is creating the sanitizers you need to keep spa water sparkling — even if you haven’t given water care a thought. Only Hot Spring offers this automated, low-maintenance saltwater system that enhances the quality of your spa water.

Enjoy clean, pure, luxurious water

Hot Spring® Spas has revolutionized the way that hot tub owners care for their water. The ACE Salt System is the first and only integrated salt water sanitizing system using diamond technology to let you enjoy the absolute best lifetime ownership experience with a Hot Spring Spa!

A Clean & Comfortable Spa

The ACE system uses a patented diamond electrode that creates active oxygen. Because cleaners are automatically generated from salt and water, spas with the ACE system lack the odor of chlorine and require fewer harsh chemicals that can irritate skin and eye. Enjoy soft skin after soaking-not the dry, itchy feeling you get from other chemicals.
