RedGard® Shower Base Kit
The RedGard® Shower Base is a cement mortar bed and curb substitute that is pre-sloped at a 2% grade to the drain. It is a 3-lb. High Density R EPS material that is encapsulated in a fiber mesh and epoxy finish. This allows for superior strength using an EPS product. The Shower Base is a nonporous finished product that has a unique drain connection that is able to use any tile shower drain. The base comes with curbs and flanges pre-attached, and is coated in RedGard brand liquid waterproofing membrane. The Shower Base is installed “just like a tile”, using a modified thin-set mortar. Installation time is minimal, with same day completion. Available in 17 size/curb configurations.
RedGard® Shower Base Kit also includes:
Fast, easy and durable drop-in, ready-to-tile shower base kit
The RedGard Shower Base is for use in commercial buildings, residential housing, and any other area where a sloped surface that is ready to be tiled is required. You can use any size tile, river rock, or other suitable surface (Corian, Acrylic) on the base.
The RedGard® Shower Base is a one piece pre-sloped component of a shower system that should be used with a cement backerboard such as WonderBoard® Lite backerboard. The base comes with curbs and flanges pre-attached, fitting 17 common floor sizes/orientations. All parts are pre-waterproofed with RedGard® brand liquid waterproofing membrane, so additional treatments are not necessary. The Shower Base replaces traditional pan liners that can easily tear, puncture or get damaged during installation. It is made of tough 3lb EPS, fiber mesh, and epoxy, resulting in a strong lightweight foundation. The Shower Base has a leak proof guarantee available for commercial and residential jobs.

SEALANT Tube ShowerSeal Polyurethane Sealant (Gray)
Any suitable substrate that you would normally build a tile shower bed on that is level; concrete, approved plywood surface, secured backer board, etc.
The RedGard Shower Base is not intended for use without a suitable substrate that can support the finished shower install.
On a suitable level substrate (using a 1/2" or larger trowel), use a modified thin-set mortar to prep surface as if laying a tile. Apply a continuous, heavy bead of polyurethane sealant on the top of the drain flange body, lay the RedGard Shower Base in place and stand on it to ensure proper bond beneath. Tighten down the locking collar of the drain and tighten the 4 bolts.
Cement backerboard installation is next; bring backer board down to the base. Install the cement backerboard so that it overlaps the flanged edges of the base and rests on top of the curb.
If waterproofing with plastic sheeting behind cement backerboard, staple plastic sheeting to walls, then secure to Shower Base by applying a thick bead of sealant along the bottom. If waterproofing walls with a liquid or fabric-applied RedGard brand waterproofing membrane or similar, apply a bead of polyurethane sealant between the board and base. Follow TCNA recommendations for CBU installation and movement joints. Apply fabric with RedGard® liquid waterproofing membrane on the perimeter to ensure the integrity of the correct mill thickness of membrane application. Paint entire shower area with RedGard® for a leak proof installation or cover with RedGard® fabric membrane for warranty requirements.
Square or rectangular with attached curb on front only. Center, left or right drain options.
