With a 1" thick perimeter, the pre-sloped shower tray allows easier construction of barrier-free showers, without unwanted or unnecessary buildup of the surrounding subfloor. All it takes is just a few simple adaptations to wood-framed construction.

PIPE SEAL

USG Durock pipe seals are designed to seal pipe penetrations in waterproof wall assemblies, like showerheads, tub spouts and body sprays. They are easy to install, while providing the perfect fit within the USG Durock Shower System.

When embedding into the mortar, make sure to remove air pockets and to ensure proper adhesion.

DRAIN ASSEMBLY AND GRATE ASSEMBLY

The drain assembly and grate assembly provide both a long-lasting performance, as well as the flexibility to accommodate a range of design and installation options.

DRAIN GRATES: With multiple designs, two sizes (4" and 5") and a number of finishes, the Durock Shower System offers more than 50 grate options, including both a Designer and Pro Series.

DESIGNER SERIES

From contemporary to classic, the Designer Series offers a range of stylish choices to fit your unique shower design. Plus, each grate is cut from a solid block of stainless steel or pure copper. This gives you a grate, and a great finish, that will look as good as new for years to come.

PRO SERIES GRATES

The Pro Series grates utilize an extremely durable, high impact-resistant, engineering-grade polycarbonate base structure wrapped in stainless steel, and equipped with a PVD finish that is bonded at the molecular level and provides trusted durability and extraordinary scratch and wear resistance.

GRATE ASSEMBLY: With an innovative square design, the USG Durock Shower System grate assembly allows greater flexibility to make adjustments when compared to competitive offerings. The grate assembly can be adjusted vertically to match tile thicknesses ranging from 1/8" to 1" thick, and it delivers up to 25% more horizontal adjustment, ensuring the grate and tile layout fit correctly.

DRAIN ASSEMBLY: The universal design of the USG Durock Shower System drain assembly simplifies installation and stands out for a number of reasons. It accepts both 4" and 5" Durock Shower System exclusive Designer and Pro Series grates. It accommodates 2" or 3" ABS or PVC waste lines, allowing for solvent-weld and no-hub connections. And it features a nonwoven fleece on both the top and the bottom of the integrated bonding flange. The fleece is co-molded with the ABS drain body to ensure the highest possible permanent bond.

Remove the construction plug from the grate tray by pushing up from the inside, then apply a light coating of paraffin or paste wax to the plug's edges to keep grout from bonding to the plug's perimeter (this is especially important when using urethane or epoxy grout which bonds more aggressively).

During the grouting process, expose the top surface of the construction plug up to its outer edges while keeping the grout joints immediately surrounding the plug as full as possible.

After grouting the shower floor, wait 24 hours before removing the construction plug. (The construction plug ensures that the grate tray remains absolutely square and in perfect form for subsequent installation of the grate. Removing the construction plug prematurely can cause the grout to crack, creating an improper fit to the grate.)

With a 1" thick perimeter, the pre-sloped shower tray allows easier construction of barrier-free showers, without unwanted or unnecessary buildup of the surrounding subfloor. All it takes is just a few simple adaptations to wood-framed construction.

CURBS

Made from the same 3-pound density molded EPS as the shower tray, the USG Durock Shower system curb delivers outstanding strength in an aesthetically pleasing height. At only 5", the curb allows for easier shower entry and exit, while creating a sleek upgrade to taller curbs offered by competitors.

Apply unmodified thin-set mortar to the subfloor and edge of the pre-sloped shower tray, curb and adjacent walls and firmly press shower curbs into the mortar.

PRE-SLOPED SHOWER TRAY

With a 3-pound density, the molded expanded polystyrene (EPS) shower tray is exceptionally strong, offering greater support for the tile covering in shower applications. Designed with an optimal 2% slope, it's also more comfortable to stand on and easily accepts a wide variety of tile shapes and sizes. Despite its strength, this lightweight shower tray easily cuts with a knife, is dust-free and comes in three sizes - a 48" x 48" center drain, a 32" x 60" center drain and a 32"x 60" offset drain.

SHOWER TRAY DISK: The USG Durock Shower System comes with a durable ABS shower tray disk that features an integrated, removable subfloor cutout template. This disk provides solid support under the drain and features clock marks for alignment to the shower tray, the grate and your preferred tile installation layout.

When using the removable subfloor cutout template on the shower tray disk, the alignment of drain grate to tile layout must be established before cutting the hole in the subfloor.

Dry-lay the tray in the correct location, then align the shower tray disk with the clock marks on the tray to the desired position before marking and cutting the hole in the subfloor.

WATERPROOFING MEMBRANE

The waterproofing membrane included with the USG Durock Shower System is part of a truly integrated and fully waterproof system. Not only stronger than many competitors' membranes, it's also significantly thinner. This means it is extremely tear resistant, minimizes buildup at seams, is more pliable and is easier to install. It also has an extremely low permeability rating, making it ideal for wet areas, including continuous-use steam showers. Conforms to ANSI A118.10, water vapor permeance of <0.075 perms per ASTM E96 Procedure E.

Click the plus signs (+) to learn about the convenient size options available for the waterproof membrane.

For corners and joints, a 5" x 50' waterproofing membrane band is included in every USG Durock Shower System kit. This size can also be purchased separately.

A 36" x 50' waterproofing membrane roll is included in every USG Durock Shower System kit. Other size options, 36' x 25' and 36 x 100', are available to purchase separately.

Start from the center of the membrane application and work toward the edges with the trowel.

Shingle-lapping of membrane is not required, provided that a minimum 2" (5 cm) overlap is maintained at all joints. Alternatively, adjoining sections of Durock Shower System Waterproofing Membrane can be abutted and then seamed with 5" (13 cm) wide Durock Shower System Waterproofing Band.

To center waterproofing band at inside wall corners, crease waterproofing band by folding in half lengthwise. Embed waterproofing band in thin-set mortar using a drywall taping knife or margin trowel.
