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 helps eliminate measuring guesswork while improving mortar bed slope consistency and reducing installation time on large shower floor layouts.

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

SereneDrains Square Shower Drain Features

• 2 inch central vertical outlet
• Fully welded and leak tested construction

• Durable corrosion-resistant finish

Square shower drains simplify tile installation because tiles can be cut using straight cuts instead of curved radius cuts required for traditional round drains.

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