Supreme is a unique linear shower drain that solves one of the biggest problems facing installers and plumbers in construction and remodeling, eliminating the need to relocate existing plumbing when the water outlet is located a few inches off-center.
This award winning product offers an independent base that houses an internal rail system which enables the grate to be in a different position than the base and the outlet. Supreme was designed with functionality and aesthetics being the primary principles in mind, creating a minimal, yet refined shower drain with a straightforward installation.
- Flexibility: Supreme’s superior design provides a flexible 8” range from the center of the shower, allowing you to center your drain without moving the existing pipe.
- Base: houses an internal rail system which enables the grate to be in a different position than the base and the outlet allowing you to center your drain without moving the existing pipe.
- Outlet: Drain base has an offset 2” outlet. This feature allows you to rotate the base to accommodate a left or right position and the sliders adjust to connect the grate in a different position than the outlet.
- Sizes: 30”, 40”, 50” & 60”. The grate can be cut to your specific length and multiple drains can be aligned to accommodate multiple outlets.
- Material: 100% Stainless Steel Marine 316.
- Easy cleaning: Read cleaning instruction for more details.
- Easy installation: Supreme is intended for use with standard waterproofing methods. Waterproofing is installed before the drain base is connected. Threaded adaptor with rubber O-ring aids adjusting the height of linear drain and securing the linear drain to the flange. See installation Instructions.
- Application: Indoor and outdoor showers.
- Kit includes: Grate, Base, Threaded Nipple/Adaptor, Wedges, Level, Key, and Stainless Steel Cutting Blade for grinder (only for Satin)
