Quick Pitch® Shower Slope System

The Quick Pitch® Float Stick System helps installers create the industry-standard 1/4 inch per foot drainage slope required for efficient shower floor drainage and long-term waterproofing performance.

The system eliminates slope guesswork while improving mortar bed consistency and reducing installation time on oversized shower floor layouts.

The included Pre-Pitch® system creates the proper subfloor pre-slope beneath the waterproof liner, helping direct moisture toward the drain weep holes.

SereneDrains Square Shower Drain Features

• 304 stainless steel body and grate
• 2 inch central vertical outlet
• Fully welded and leak tested construction
• No visible screws
• Modern square drain design
• Durable corrosion-resistant finish
• Easy maintenance and cleaning

SereneDrains square shower drains are designed to work with standard tile sizes including 1/2 inch, 1 inch, 2 inch, and 4 inch tile layouts, helping reduce tile cutting time and simplify installation.

Square drains allow for straight tile cuts instead of curved radius cuts commonly required around traditional round drains.

Composeal Gold Waterproofing Membrane

Composeal Gold vinyl shower pan membrane is designed for use beneath mortar bed tile shower floors to provide long-term waterproofing protection in residential and commercial shower installations.

The membrane is commonly installed beneath tile and stone shower floors over wood or concrete substrates and complies with major plumbing code requirements.

Professional Waterproofing Installation

Proper shower pan installation includes creating the correct pre-slope beneath the liner, extending the liner above curb height, protecting weep holes, and performing a full 24-hour water test before final tile installation.

The included curb protectors, inside corners, and solvent cement help simplify waterproof shower pan installation while improving long-term leak protection.
