Rough Plumbing a Shower Drain: A Comprehensive Guide
Embarking on a DIY shower renovation or new construction project? One crucial aspect you'll need to tackle is the rough plumbing of the shower drain. This process involves installing the drain and connecting it to the main waste line, ensuring proper water flow and preventing future issues. Let's dive into a step-by-step guide to help you master this essential skill.
Understanding Shower Drain Types
Before we start, it's essential to understand the two primary shower drain types:
- Standard Drain: Found in most residential showers, these drains are connected to a 2-inch drain pipe.
- Linear Drain: Popular in modern and custom showers, these drains are connected to a 2-inch or larger drain pipe and can be installed in various patterns.
This guide will focus on standard drains, as they are more common and straightforward to install.
Gather Your Tools and Materials
Before you begin, ensure you have the following tools and materials:
- Shower drain assembly (including drain body, strainer, and escutcheon)
- Pipe cutter or hacksaw
- Teflon tape
- Plumber's putty
- Adjustable wrench
- PVC cement (if using PVC pipes)
- PVC primer (if using PVC pipes)
- Measuring tape
- Level
Measure and Mark the Drain Location
First, determine the exact location of the shower drain. It should be centered beneath the showerhead and at least 2 inches away from the shower walls. Use a measuring tape and a pencil to mark the drain's center point on the shower base or subfloor.
Cut the Drain Hole
Using a hole saw or reciprocating saw, cut out the drain hole at the marked location. Ensure the hole is slightly larger than the drain body to accommodate the drain assembly and allow for easy installation.
Install the Drain Body
Insert the drain body into the hole from below the shower base or subfloor. Ensure it's level and centered. Apply plumber's putty around the drain body's base to create a watertight seal. Gently press the drain body into place, and allow the putty to set for a few minutes.
Connect the Drain to the Waste Line
Measure and cut the drain pipe (usually 2-inch PVC or ABS) to connect the shower drain to the main waste line. Apply Teflon tape to the threads of the drain body and the pipe's end. If using PVC pipes, apply PVC primer and cement to create a strong, watertight bond.
Insert one end of the pipe into the drain body, and the other end into the main waste line. Use an adjustable wrench to secure the connection, being careful not to overtighten and damage the pipe.
Install the Strainer and Escutcheon
From above the shower base, insert the drain strainer into the drain body. Secure it with the provided screws or set screws. Next, install the escutcheon, which covers the drain body and provides a finished look.
Test the Drain
Before tiling or installing the shower surround, test the drain to ensure it's functioning correctly. Pour water into the shower and check for proper drainage. If the water drains slowly or not at all, you may need to adjust the pipe or check for obstructions.
Final Thoughts
Rough plumbing a shower drain may seem daunting, but with the right tools, materials, and guidance, it's a task well within the reach of the average DIY enthusiast. By following this comprehensive guide, you'll be well on your way to a successful shower renovation or new construction project. Happy plumbing!
