A ShowerSlope™ is manufactured with KBRS Hard Core Technology®.

A shower’s tile assembly is only as good as the substrate in which it is installed. A KBRS ShowerSlope™ is absolutely the most rock-solid prefabricated tileable shower pan available. A ShowerSlope™ is a pre-sloped, structurally sound, textured substrate that will prevent tile assembly failure due to ponding water, deflection, and poor thin-set bonding.

A KBRS ShowerSlope™ can be Cut-to-Fit in the field.

Rarely are walls perfectly square, and shower drain locations are usually offset as to not interfere with the buildings floor joists. A ShowerSlope™ is manufactured with these challenges in mind. The shower slope is slightly oversized so that it can be cut to accommodate out-of-square walls and offset drain locations.

A KBRS ShowerSlope™ Does Not Require any Special Drains.

A ShowerSlope™ easily clamps to most popular brands of residential tile shower drains. Custom drain connections for larger commercial tile shower drains are available upon request.

What's the difference between the ShowerSlope™ & Tile-Basin®?

The ShowerSlope™ is identical to the Tile-Basin® with two exceptions. The ShowerSlope™ DOES NOT come factory prepped with an elastomeric waterproofing membrane coating, or with factory installed perimeter components (i.e. flange or curb). This allows the ShowerSlope™ to be "cut-to-fit" in the field. An elastomeric waterproofing membrane must be properly applied to surfaces of the ShowerSlope™ and to the seams where the ShowerSlope™ and the tile backer board meet.

Linear ShowerSlope™ Installation

The KBRS Linear Line is a rock-solid alternative to a field-sloped mortar bed. Once installed, the Linear ShowerSlope™ can be waterproofed using either a liquid-applied or bonded sheet-applied positive side membrane. Our linear shower pans are lightweight, yet will provide the superior strength and durability necessary for a successful tile shower installation.

KBRS Linear Line shower pans are easily installed using modified thin-set mortar. Linear shower pans are available in standard sizes and unlimited custom sizes (up to 9500 square inches).

The KBRS Linear ShowerSlope™ comes with a 1-1/4" leading edge that is designed with a linear drain slot, which is ideal when installing linear drains.
