Available as an accessory, a glass heater door not only adds to the atmosphere of your hot tub by allowing you to enjoy the cozy glow of the fire, but also makes it easier to monitor wood consumption. The aesthetically pleasing glass heater door is made out of heat-resistant ceramic glass. The glass door is compatible with most Kirami hot tub heaters: MICU, MACU, CULT and new CUBE heaters (those manufactured after 2017) with door dimensions of width 32.5 cm and height 39.5 cm.
