How to Plug a Shower Drain

Are you tired of having a slow draining shower? Do you dread standing in ankle-deep water every time you take a shower? If so, it’s time to learn how to plug a shower drain.

Plugging a shower drain is a straightforward task that can be necessary in various situations, such as when you need to block water flow during repairs, cleaning, or filling the tub for other purposes. Whether you’re trying to stop debris from entering the pipes or temporarily seal the drain, knowing how to do this properly is a useful skill.

This guide on plugging a shower drain will walk you through the steps and tools required to effectively and securely plug a shower drain. Let’s get started!

What Are the Causes of a Slow Draining Shower?

Before we dive into how to plug a shower drain, it’s essential to understand why your shower may be draining slowly.

1. Hair Build-Up: One of the most common causes of a slow draining shower is hair build-up in the drain. As you wash your hair, strands can easily get caught in the drain and accumulate over time, leading to clogs.
2. Soap Scum and Residue: Soap scum and residue from shampoo and body wash can also contribute to slow draining showers. These substances can stick to the sides of pipes and accumulate debris, causing blockages.
3. Mineral Deposits: Depending on where you live, mineral deposits can also contribute to slow draining showers. Hard water, which contains high levels of calcium and magnesium, can leave behind mineral deposits in pipes, leading to blockages.
4. Pipe Issues: In some cases, the issue may not be with the shower drain but the pipes connected to it. Old or damaged pipes can cause drainage problems and require professional repairs.

What Will You Need?

To plug a shower drain effectively, you’ll need a few tools that are readily available at hardware stores or online:

• Rubber Drain Stopper: This is a common and affordable tool used to plug drains temporarily. It’s made of rubber and has a flat circular shape with ridges on one side to create a seal.
• Plumber’s Putty: Plumber’s putty is a soft, moldable substance that creates watertight seals around drains and faucets. It’s ideal for plugging shower drains as it can be easily removed and reused.
• Silicone Caulk: If you’re looking for a more permanent solution, silicone caulk can be used to create a firm seal around the edges of the drain cover.
• Plunger: A plunger is an essential tool in any household and can come in handy if the cause of your slow draining shower is clogs. It uses suction to dislodge debris and clear blockages in pipes.

Once you have these tools, you’re ready to plug your shower drain.

8 Easy Steps on How to Plug a Shower Drain

Step 1. Clean the Drain Area:

Before attempting to plug your shower drain, ensure the area around the drain is clean and free from debris. Use a mild cleaning solution or soap and water to clean the edges and surface of the drain thoroughly. This step is crucial as it removes soap scum, hair, and any other residues that might prevent a proper seal. For stubborn buildup, gently scrub the area with a small brush or an old toothbrush.

Once clean, dry the drain with a cloth or paper towel to ensure the sealing materials will adhere effectively. Proper preparation will help maintain a secure and watertight seal.

Step 2. Choose the Right Plug or Cover: 

Select a suitable plug, stopper, or shower drain cover that fits the size and type of your drain. Shower drains come in various designs, so ensuring the plug fits snugly is essential to prevent leaks. If you’re unsure, measure the diameter of your drain or refer to the manufacturer’s specifications for compatibility. Standard options include rubber stoppers, drain covers with suction cups, or twist-and-seal plugs. The correct plug or cover is key to achieving an effective seal and avoiding potential issues.

Step 3. Apply the Seal or Insert the Plug: 

Carefully insert the chosen plug or stopper into the shower drain, ensuring it fits securely. If you are using a twist-and-seal plug, align it properly and twist until you feel it tighten into place. Press firmly for rubber stoppers or suction-based covers to create a strong seal. Take a moment to check for any gaps or misalignments, as these can lead to leaks. Proper application is crucial for an effective seal that prevents water from draining unintentionally during use.

Step 4. Test the Seal: 

Once the plug or stopper is securely in place, test the seal by running a small amount of water into the shower. Monitor closely to ensure no water seeps through around the edges of the plug or cover. If you notice any leaks, recheck the placement and adjust as necessary. A properly fitted seal will hold water effectively, allowing you to confidently proceed. Testing the seal before fully relying on it can save time and prevent potential messes.

Step 5. Fill the Shower with Water: 

With the seal successfully tested, begin filling the shower with water to your desired level. Ensure the water temperature is appropriate and suits your intended purpose, whether for soaking, cleaning, or any other activity. Keep an eye on the water level as you fill to avoid overflows. Once the water reaches the desired depth, turn off the faucet and double-check the seal to confirm it remains secure. Proper water management at this stage ensures a hassle-free experience.

Step 6. Add Plumber’s Putty or Silicone Caulk: 

To enhance the seal and ensure maximum waterproofing, apply plumber’s putty or silicone caulk around the edges where the shower drain or plug meets the surface. Plumber’s putty is a malleable material that adheres well to seals, creating a watertight barrier, while silicone caulk provides a durable, long-lasting solution against leaks.

Begin by cleaning the area thoroughly to remove debris, dirt, or moisture, as a clean surface will allow the material to adhere properly. If using plumber’s putty, roll a small amount into a thin rope-like shape, and press it evenly around the edges of the seal. Alternatively, if you opt for silicone caulk, use a caulking gun to carefully run a steady bead of the caulk along the same area, ensuring complete coverage.

Smooth the applied putty or caulk with your finger or a tool to create an even finish, and wipe away any excess material before it hardens. Allow sufficient time for the material to set or cure as specified by the manufacturer’s instructions.

Step 7. Remove the Plug or Drain Cover:

Carefully unscrew or lift the plug or drain cover, depending on its design. Be sure to use the proper tool for the job, such as a screwdriver or a specialized drain key, to avoid damaging the fixture. If the cover seems stuck due to accumulated grime or mineral deposits, gently use a penetrating lubricant or a mix of vinegar and warm water to loosen it. Patience is essential during this step, as forcing the plug or cover could result in scratches or cracks.

Once removed, inspect the area underneath for any debris or residue that may block the drain, and clean it thoroughly before proceeding to the next step. This ensures optimal functionality and a clean base for reassembly or further maintenance.

Step 8. Clean and Inspect the Drain Components:

After removing the plug or drain cover and clearing debris, thoroughly clean all components, including the plug, cover, and surrounding area. Use a brush and a mild cleaning solution to scrub away grime, mineral buildup, or soap scum. Inspect each part for signs of wear or damage, such as cracks, rust, or corrosion. If any components are worn or broken, consider replacing them before reassembly to ensure long-lasting performance. Proper cleaning and inspection not only improve the drain’s efficiency but also help prevent future issues.

By following these steps, you can achieve a secure and watertight seal on your shower drain, allowing you to enjoy your showers without any unwanted leaks or spills.

5 Things You Should Avoid

1. Using Improper Materials: Avoid using tissue paper, cloth, or plastic not designed for plumbing purposes. These can lead to blockages or deteriorate over time, causing further issues.

2. Ignoring Proper Seals: Skipping a rubber plug or a well-fitted stopper can result in leaks and inefficiency. Always ensure the seal is airtight to prevent water from escaping.

3. Applying Excessive Force: Forcing objects into the drain to form a plug can damage the pipes or the drain itself. Always use tools or plugs that are the appropriate size and fit.

4. Neglecting to Clean the Drain: Plugging a drain without clearing debris or hair can lead to slow drainage or backflow. Always clean the drain thoroughly before sealing it.

5. Leaving Temporary Fixes Permanent: Relying on makeshift solutions like tape or improvised stoppers for long periods can cause long-term plumbing issues. Use durable, properly designed plugs or stoppers for a lasting solution.
