Guide to Moving a Shower Drain for Bathroom Renovation

When remodeling a bathroom or installing a new shower, you may find it necessary to relocate the shower drain. Moving the drain can be a daunting task, but with the right tools and knowledge, it can be done successfully. This guide will walk you through the steps to relocate a shower drain, ensuring that your new shower is properly installed and functioning.

Step 1: Prepare for the Relocation

Before you begin the relocation process, it is important to gather all the necessary tools and materials. This may include a reciprocating saw, a wrench, a hammer, PVC pipes, cement, and a drain assembly. Additionally, it is crucial to familiarize yourself with the local building codes and regulations, as they may dictate specific requirements for the shower drain relocation.

Step 2: Remove the Old Shower Drain

The next step in the relocation process is to remove the old shower drain. This can usually be done by using a wrench to loosen and unscrew the drain assembly from the drainpipe. Once the drain assembly is removed, you may need to cut away any surrounding tiles or flooring to access the drainpipe.

Step 3: Determine the New Drain Location

Once the old drain is removed, you can determine the new drain location. It is important to choose a location that is not only convenient for the shower installation but also meets the building code requirements. Ensure that the new location has proper slope for drainage and is accessible for future maintenance.

Preparation for Relocating a Shower Drain

Before you begin the process of relocating a shower drain, it is important to gather all the necessary tools and materials. This will ensure that you have everything you need to successfully complete the project. Here are some steps to help you prepare:

1. Measure and plan: Start by measuring the new location for the shower drain. Be sure to take into account any required slope for proper drainage. Use a pencil and measuring tape to mark the new position on the floor.

2. Turn off the water: Locate the main water supply for the shower and turn it off. This will prevent any water from flowing while you work on relocating the drain.

3. Gather your tools: You will need a variety of tools for this project, including a reciprocating saw, pipe cutters, pliers, wrenches, and a drain wrench. Make sure you have all the necessary tools on hand before you begin.

4. Acquire materials: You may need to purchase additional materials such as PVC pipe, fittings, and glue. Take note of the size and type of pipe needed for your specific shower drain system.

5. Protect the surrounding area: To prevent any damage to the surrounding floor or walls, use drop cloths or plastic sheets to cover the area around the shower. This will catch any debris or water that may be produced during the relocation process.

6. Research local building codes: Before you start the project, check with your local building codes to ensure that you adhere to any regulations or permits required for plumbing work. This will help prevent any potential issues down the line.

By following these preparation steps, you will be well-equipped and ready to continue with the process of relocating your shower drain. Remember to take your time and proceed with caution to ensure a successful project.

Turn Off the Water Supply

Before you begin relocating a shower drain, it is important to turn off the water supply to prevent any accidents or leaks. Locate the main water shut-off valve for your house, which is typically found in the basement or utility room. The valve may be a lever, knob, or wheel. Turn the valve clockwise to shut off the water supply.

Remove the Old Shower Drain

When relocating a shower drain, the first step is to remove the old drain. This can be done by following these steps:

1. Start by removing the shower grate or cover. This can usually be done by unscrewing or lifting it off, depending on the type of drain you have.

2. Once the grate or cover is removed, you will see the drain pipe. Use a wrench or pliers to loosen the locking nut that holds the drain in place.

3. After loosening the locking nut, carefully lift the old drain out of the shower floor. Be cautious not to damage the surrounding tiles or flooring.

4. Inspect the old drain for any signs of damage or wear. If the drain is in poor condition, it may be necessary to replace it entirely. Otherwise, you can reuse the drain for the new location.

5. Clean the area around the old drain, removing any debris or residue. This will ensure a clean surface for installing the new drain.

By following these steps, you can successfully remove the old shower drain and prepare the area for installing the new drain in its relocated position.

Determine the New Location for the Shower Drain

1. Measure and Mark

Before you begin relocating the shower drain, you need to determine the new location. Start by measuring the distance between the existing drain and the desired location for the new drain. Use a tape measure and mark the new location with a pencil or marker.

2. Assess Plumbing and Structure

Next, you need to assess the existing plumbing and structural components to determine if the new location is feasible. Consider the distance from the main drain line, the slope of the pipes, and any obstacles such as floor joists or concrete slabs. If there are any concerns, consult a professional plumber or contractor.

3. Plan for Proper Drainage

It’s essential to ensure that the new location will provide adequate drainage for the shower. Gravity plays a crucial role in draining water, so you need to ensure that the new drain location is lower than the shower floor. If necessary, plan for the installation of a new floor slope to direct water towards the new drain location.

4. Consider Accessibility

When determining the new location for the shower drain, consider accessibility. The drain should be easily accessible for future maintenance or repairs. Avoid placing the drain under fixtures or in hard-to-reach areas. It’s also important to comply with local building codes and regulations regarding drain placement.

5. Consult a Professional

If you are uncertain about the technical aspects of relocating a shower drain, it’s always best to consult a professional. A licensed plumber or contractor can assess your specific situation and provide expert advice on the feasibility and requirements of relocating the drain. They can also ensure that the work is done safely and up to code.

Create a New Hole for the Shower Drain

Once you have determined the new location for your shower drain, it’s time to create a new hole in the subfloor to accommodate the drain pipe. Follow these steps to relocate the shower drain:

  1. Measure and mark the new location for the drain hole on the subfloor. Use a measuring tape to ensure accurate placement.
  2. Drill a pilot hole through the subfloor at the center of the marked location. This will serve as a starting point for the larger hole.
  3. Using a reciprocating saw or jigsaw, carefully cut out the hole for the shower drain. Make sure to stay within the marked lines and create a clean, circular cut.
  4. Test fit the new drain pipe into the hole to ensure a proper fit. If necessary, use a file or sandpaper to remove any rough edges or adjust the size of the hole.
  5. Secure the drain pipe in place by attaching the appropriate connectors or fittings. Make sure the pipe is level and tightly sealed to prevent leaks.
  6. Apply a layer of waterproof sealant or plumber’s putty around the edges of the drain pipe to further ensure a watertight seal.
  7. Replace the subfloor and install the shower base or pan over the newly relocated drain hole. Follow the manufacturer’s instructions for proper installation.
  8. Connect the shower drain to the existing plumbing system, making sure to properly align and secure all connections.
  9. Test the drainage system by running water through the shower. Check for any leaks or improper drainage, and make adjustments as needed.

Relocating a shower drain may require some skill and knowledge of plumbing systems. If you are unsure about any step or encounter difficulties, it is recommended to consult a professional plumber for assistance.

Install the New Shower Drain

Once you have removed the old shower drain, you can now proceed with installing the new one. Follow these steps to install the new shower drain:

  1. Measure and mark the location of the new drain on the shower base. Use a tape measure and a pencil to carefully mark the center of the drain.
  2. Place a small bead of plumber’s putty around the bottom lip of the drain. This will create a watertight seal when the drain is attached to the shower base.
  3. Insert the drain into the hole on the shower base, making sure it is positioned correctly and centered over the mark you made earlier.
  4. Attach the drain to the shower base by tightening the locking ring. Use a drain wrench or pliers to securely tighten the ring until the drain is firmly in place.
  5. Test the drain for leaks by pouring water into the shower base and checking for any water seepage around the drain area. If there are any leaks, tighten the locking ring further until the leak stops.
  6. Once the drain is securely in place and no leaks are detected, apply a thin layer of silicone sealant around the edges of the drain to ensure a watertight seal. Smooth out the sealant using your finger or a caulking tool.
  7. Allow the sealant to dry completely before using the shower. This usually takes about 24 hours, but refer to the manufacturer’s instructions for specific drying times.

Installing a new shower drain can be a challenging task, so if you are unsure of your plumbing skills, it is recommended to hire a professional plumber to assist you. Following these steps will help ensure a proper installation and prevent any future issues with your shower drain.
