Shut Off Water: Locate and turn off water supply to avoid leaks during the process
Before you begin the process of moving a shower drain, it's crucial to shut off the water supply to prevent any accidental leaks or flooding. Start by identifying the main water shut-off valve for your home, typically located near the water meter or where the main water line enters your house. This valve controls the entire water supply to your home. Turn it clockwise to shut off the water completely. If you’re unsure about its location, consult your home’s plumbing diagram or contact a professional for guidance. Shutting off the main valve ensures that no water flows into the plumbing system during the drain relocation process.
In addition to the main shut-off valve, locate the individual water supply valves for your shower. These are usually found under the sink or in a nearby utility closet, depending on your plumbing layout. Turn these valves clockwise to shut off the water specifically to the shower area. This step is essential because it isolates the water supply to the shower, minimizing the risk of leaks while you work on the drain. If your shower does not have individual shut-off valves, rely on the main shut-off valve, but double-check that the water is completely off before proceeding.
After turning off the water supply, open the shower faucet to release any residual water in the pipes. This step ensures that no water remains under pressure in the lines, reducing the risk of accidental spills or leaks during the drain relocation. Let the water run until it stops completely, confirming that the supply has been successfully shut off. If water continues to flow, recheck the shut-off valves to ensure they are fully closed.
To further safeguard against leaks, place a bucket or towel under the shower area where you’ll be working. Even with the water supply off, there may be small amounts of water left in the pipes or fixtures. Having a bucket or towel ready will catch any drips and keep your workspace dry. This precautionary measure also helps protect your bathroom floor from water damage.
Finally, verify that the water is indeed off by attempting to run the shower again. If no water comes out, you’ve successfully shut off the supply and can proceed with moving the shower drain. If water still flows, revisit the shut-off valves and ensure they are fully closed. Taking the time to properly shut off the water supply is a critical step that ensures a safe and leak-free process when relocating your shower drain.

Remove Old Drain: Unscrew the old drain cover and use a wrench to detach the pipe
Before you begin the process of moving a shower drain, it's essential to start by removing the old drain assembly. The first step in this process is to unscrew the old drain cover. Most drain covers are held in place by screws or a threaded mechanism. Use a screwdriver to carefully remove any visible screws securing the cover. If the cover is threaded, grip it firmly with a pair of pliers or a specialized drain cover removal tool and turn it counterclockwise to unscrew it. Be cautious not to damage the surrounding shower surface during this step.
Once the drain cover is removed, you’ll expose the drain body and the pipe connected to it. The next step is to detach the pipe from the drain body. This pipe is typically secured with a nut or coupling located just below the drain. Position a wrench around the nut and turn it counterclockwise to loosen it. If the nut is corroded or difficult to turn, apply penetrating oil and allow it to sit for a few minutes before attempting again. Ensure you have a firm grip on the wrench to avoid slipping, which could damage the pipe or surrounding area.
After loosening the nut, carefully pull the pipe away from the drain body. Depending on the setup, you may need to wiggle the pipe slightly to free it from any seals or gaskets. Take note of how the pipe is positioned and connected, as this information will be useful when installing the new drain. If the pipe is stuck, avoid forcing it, as this could cause damage. Instead, inspect the connection for any additional fasteners or obstructions that may need to be addressed.
With the pipe detached, inspect the drain body for any remaining debris or old sealant. Use a utility knife or scraper to remove any old caulk or residue around the drain opening. This ensures a clean surface for the installation of the new drain. If the drain body itself is damaged or outdated, consider replacing it entirely to ensure a secure and leak-free installation.
Finally, double-check that all components of the old drain assembly have been removed and that the area is ready for the new drain installation. Properly disposing of the old drain cover, pipe, and any other removed parts is also important. By following these steps to unscrew the old drain cover and use a wrench to detach the pipe, you’ll have successfully completed the first critical phase of moving a shower drain.

Check for water pooling around the drain or seeping through the floor or walls, as this could indicate a hidden leak. Additionally, inspect the ceiling or floor below the shower for any signs of moisture or dripping, which may suggest a leak in the drainpipe or its connections. If any issues are detected, turn off the water supply and investigate further to identify and fix the source of the leak.
Next, ensure proper drainage by filling the shower pan or floor with a few inches of water and observing how quickly it drains. A properly installed drain should empty smoothly without leaving standing water. If the water drains slowly or not at all, there may be a clog or improper slope in the drainpipe. Use a flashlight to inspect the drain for debris or obstructions, and clear them if necessary. If the issue persists, check the slope of the drainpipe to ensure it is angled correctly to allow water to flow toward the main drain line.
Once you’ve confirmed there are no leaks and the drainage is functioning correctly, test the system under pressure by taking a full shower. Pay attention to the drain’s performance and the surrounding area for any signs of moisture or leakage. After the shower, inspect the drain, walls, and floor again to ensure no water has escaped. If everything remains dry and the drain works efficiently, you can proceed with finishing the shower installation, such as tiling or sealing the area.
Finally, double-check all connections one last time before completing the project. Tighten any fittings if necessary, but avoid over-tightening, as this can damage the pipes or threads. Once you’re confident in the integrity of the plumbing, you can finish the shower area according to your design plans. Testing for leaks and ensuring proper drainage is a crucial step that prevents future water damage and ensures the longevity of your shower system.
