Application: Wall Hung Toilet Back Wall System
A wall hung toilet requires a stable and durable support structure around the concealed cistern.
Traditional solutions often use:
Cement board → heavy and difficult to handle
Wooden frame → risk of moisture damage
Brick construction → time-consuming and labor intensive
LUX XPS Tile Backer Board creates a faster and cleaner installation process while providing excellent waterproof protection for wet areas.
