Planning a Traditional Shower Pan with Pre-Pitch, Quick Pitch and SereneDrains
A properly constructed shower pan is the foundation of every successful tile shower installation. Whether you are using a PVC liner, Chloraloy membrane, or a liquid waterproofing system, proper planning before construction begins helps ensure reliable drainage and long-term performance.
This guide explains how to estimate materials, determine slope requirements, and prepare for installation using the Pre-Pitch and Quick Pitch systems together with a SereneDrains square shower drain.
Unlike bonded waterproofing systems that place the waterproof layer directly beneath the tile, traditional shower pan construction typically incorporates a sloped mortar bed, waterproof liner, and a final mortar bed above the waterproofing layer.
Careful planning at the beginning of the project helps simplify installation and reduces material waste.
Step 1: Determine the Shower Size and Drain Location
The first step is determining the overall size and shape of the shower, including the drain type and its location.
Drain placement affects the slope of the shower floor, the amount of mortar required, and the number of Pre-Pitch and Quick Pitch components needed for the installation.
Whether using a centered drain or an offset drain design, accurate measurements are essential before ordering materials.
Step 2: Measure Distances to Walls, Curbs and Corners
With the rough curb framing in place, measure from the center of the drain to each wall, corner, and curb location.
These measurements help determine the quantity of slope components required and establish the overall layout of the shower floor.
Accurate measurements are especially important for custom shower designs and larger shower enclosures.
Selecting Standard or Extended Float Sticks
Both Pre-Pitch and Quick Pitch systems utilize float sticks that establish the proper slope toward the drain.
Standard float sticks are approximately 36 inches long. If the distance from the drain to the shower perimeter exceeds 36 inches, extension kits may be required.
Using the proper combination of standard and extended float sticks helps maintain a consistent slope throughout the entire shower floor.
Step 3: Plan Float Stick Placement
Beginning at a corner, mark the perimeter of the shower in approximately 2 to 2½ foot increments while ensuring that a float stick is positioned at each corner.
Closer spacing between float sticks generally makes screeding the mortar bed easier and helps create a smoother finished surface.
Proper placement of the float sticks provides the framework needed to establish consistent drainage toward the shower drain.
Once the shower layout has been established, the next step is calculating curb materials, selecting the proper drain components, determining waterproofing requirements, and estimating the amount of deck mud needed for the installation.
Step 4: Determine Kirb Perfect Requirements
The shower curb is an essential component of any traditional shower pan because it helps contain water within the shower enclosure while providing a solid foundation for tile installation.
Kirb Perfect curb sections simplify curb construction by creating a consistent form that can be filled with mortar and finished with tile.
To determine how many sections are required, measure the total curb length in 30-inch increments. Individual sections connect together using integrated dovetail connectors, allowing for virtually any curb length or configuration.
Step 5: Select the Proper Drain Components
Before installation begins, determine which drain assembly will be used in the shower.
Standard Quick Pitch kits include a center ring designed to work with traditional shower drains. When using a SereneDrains square shower drain or certain 3-inch drain assemblies, a Universal Center Ring may be required.
The Universal Center Ring allows the Quick Pitch float sticks to integrate properly with square shower drain installations while maintaining a consistent slope around the drain area.
Step 6: Calculate Waterproofing Material Requirements
Traditional shower pans typically utilize PVC liners, Chloraloy membranes, or approved liquid waterproofing systems.
To determine the required waterproofing material, measure the length and width of the shower floor and add sufficient material so the waterproofing extends at least 3 inches above the finished curb height on all walls.
The waterproofing material must also completely cover the shower curb and any adjacent waterproofed areas.
Proper waterproofing coverage is critical to protecting the structure from moisture intrusion.
Step 7: Calculate Deck Mud Requirements
Once the shower dimensions and waterproofing materials have been determined, estimate the amount of deck mud required for the mortar beds.
A typical deck mud mixture consists of:
- 1 part Portland cement
- 4 parts clean sand
For traditional shower pan construction utilizing both Pre-Pitch and Quick Pitch systems, a common estimating guideline is approximately 12.5 pounds of deck mud per square foot of shower floor.
For example:
- 3 ft. × 5 ft. shower = 15 square feet
- 15 × 12.5 lbs. = approximately 188 lbs. of deck mud
Having sufficient material on hand before installation begins helps prevent delays and ensures consistent mortar placement throughout the project.
Step 8: Review Installation Instructions Before Starting
Before mixing mortar or beginning construction, take time to review all installation instructions for the Pre-Pitch system, Quick Pitch system, waterproofing materials, shower drain assembly, and curb components.
Understanding the installation sequence beforehand can help avoid mistakes and improve overall project efficiency.
Proper preparation is one of the most important factors in building a successful and long-lasting shower system.
Benefits of the Pre-Pitch and Quick Pitch System
Using both Pre-Pitch and Quick Pitch components helps simplify traditional shower pan construction while improving consistency throughout the installation.
- Creates proper slope beneath the waterproof liner
- Provides a consistent finished slope toward the drain
- Simplifies custom shower layouts
- Works with traditional waterproof liners and liquid membranes
- Compatible with square shower drains
- Reduces guesswork during mortar bed installation
When combined with quality waterproofing materials and a properly installed drain assembly, these systems help create a durable shower pan designed for years of reliable performance.
