Handi-Kirb Installation Instructions

Handi-Kirb – Installation Instructions

This step-by-step guide explains how to install a Handi-Kirb shower curb using the Quick Pitch and Pre Pitch system. This method ensures proper slope, effective drainage, and a durable, waterproof shower base suitable for both contractors and DIY installations.

The Handi-Kirb system is designed as a ready-to-tile shower curb, simplifying installation while maintaining a clean, professional finish. It is also ideal for accessible and low-profile shower applications.

Standard Mud Bed Installation Using Liquid Membrane

1. Cut the curb to fit the shower opening.

2. Install the Pre Pitch system (refer to Pre Pitch installation instructions).

3. Apply mortar before placing the curb. Position the curb and press firmly into place.

4. Secure the Handi-Kirb: Concrete floors: use 1-1/2” Tapcon screws
Wood subfloors: use 1” wood screws

5. Fill and screed the curb smooth. Allow the mortar to dry overnight.

Liquid Waterproofing Installation

Always follow the membrane manufacturer’s specifications.

1. Apply fiberglass mesh tape on all seams using liquid waterproofing and a brush.

2. Apply waterproofing to all walls from the shower head down.

3. Before coating the floor, install a drain flashing such as Blanke Aqua Shield around the drain.

4. Apply two heavy coats of waterproofing on the shower floor. Allow to dry completely before proceeding.
Proper membrane thickness is critical for waterproof performance.
