UltraFit™ Integrated Heater
Built-in UltraFit™ integrated heater
The Lay-Z-Spa UltraFit™ integrated multifunction heater offers better efficiency, more space around the hot tub and an all-round more sleek design to the look of your hot tub.
The built-in heater system is fully integrated into the construction of the Lay-Z-Spa hot tub, whether that's foam wall or inflatable. The only part you see is the flip-up control panel that gives you easy access to all the functions and can be folded out of sight.
