The Schluter Kerdi Board Waterproof Shower Kit bundles the panels and sealing parts needed to make tub and acrylic-shower walls waterproof and tile-ready. It includes eight Kerdi-Board panels covering about 101 sq ft, a roll of Kerdi-Band, pipe and mixing-valve seals, screws and washers, and two tubes of Kerdi-Fix. It suits a remodeler or confident DIYer waterproofing a standard tub surround or shower wall up to the showerhead. Against cement board and liquid membranes, the foam panels are lighter and cut with a utility knife, but they cost more and need solid blocking for grab bars.

Tilers and DIYers rate the kit highly for turning a messy waterproofing job into a quick, clean panel install. Complaints center on the quantity of panels and sealant for anything beyond a basic surround.
This kit has the components to waterproof the walls of a bathtub or acrylic shower base and get them ready for tile. It uses KERDI-BOARD waterproof building panels.
The panels cover up to 101 ft² (9.4 m²) of wall area. With standard 8 ft. ceilings, that is 12 linear feet (3.6 m) of wall. Waterproofing should reach at least the height of the showerhead. Applying panels to the ceiling is optional for bathtub surrounds and showers.
Longer or taller walls, or installations that include a ceiling, may need additional KERDI-BOARD or KERDI-BAND. Grab bars and other heavy objects must be anchored in the structure or in solid blocking behind the panels. Instructions for other uses, such as fully embedded or spot-bonded over solid backing, are in the Schluter-KERDI-BOARD technical data sheet.
