Using the Brizo 36-inch Linear Shower Drain Rough is straightforward. First, choose the right location for the drain in your shower. Use the height-adjusting risers and tiling aid to install it properly according to your floor substrate, whether it's concrete, wood, or LEWIS sheet. After installation, make sure to order the drain trim separately and attach it. When using the shower, the drain will efficiently handle water with its 11 GPM (42 L/min) capacity. The patented Water Protection System will keep your shower watertight. For maintenance, regularly clean the hair catcher to prevent clogs. Avoid using harsh chemicals that could damage the stainless - steel channel. If you notice any leaks or issues, check the installation and the Water Protection System.
