What You'll Learn

Remove Hair Clogs
To effectively remove hair clogs from your shower drain, start by gathering the necessary tools: a pair of rubber gloves, a screwdriver (if your drain cover has screws), a wire hanger or a drain snake, and a bucket. Hair clogs are a common issue in shower drains, and addressing them promptly can prevent water from pooling and slow drainage. Begin by removing the drain cover. If it’s screwed in, use the screwdriver to carefully lift it off. If it’s a pop-up or snap-on type, gently pry it up using a flat tool or your fingers. Place the cover aside to avoid losing any screws or parts.
Once the drain cover is removed, visually inspect the drain for hair buildup. Often, you’ll see a clump of hair just below the surface. If the clog is shallow, you can use your gloved hand or a pair of tweezers to pull out the hair. Be thorough, as leaving even a small amount of hair can cause the drain to clog again quickly. Dispose of the hair in a trash bin to avoid further plumbing issues.
For deeper clogs, straighten a wire hanger and create a small hook at one end. Insert the hooked end into the drain and gently push it past the initial curve of the pipe. Rotate the hanger to catch the hair and slowly pull it out. Repeat this process until no more hair is retrieved. Alternatively, use a drain snake, which is a flexible tool designed specifically for this purpose. Insert the snake into the drain, twist it to grab the hair, and pull it back out. This method is particularly effective for stubborn clogs that are further down the pipe.
After removing the hair, run hot water down the drain to flush out any remaining debris. If the water still drains slowly, pour a mixture of baking soda and vinegar into the drain. Let it sit for 15–30 minutes, then flush it with hot water again. This natural cleaner helps break down any residual buildup and leaves the drain smelling fresh. Finally, replace the drain cover securely, ensuring all screws are tightened or the cover snaps back into place properly.
Regular maintenance can prevent hair clogs from recurring. Consider installing a hair catcher over the drain to trap hair before it enters the pipes. Clean the hair catcher regularly to maintain optimal drainage. Additionally, flush your drain with hot water weekly to help dissolve soap scum and prevent hair from sticking to the pipe walls. By following these steps, you can keep your shower drain clear and functioning efficiently.

Use Baking Soda & Vinegar
Using baking soda and vinegar is a natural, effective, and eco-friendly method to lower shower drain clogs and improve drainage. This method works by creating a chemical reaction that helps break down debris, soap scum, and hair buildup in the drain. Start by removing any visible debris or hair from the drain using your fingers, a hook, or a pair of tweezers. This initial step ensures that the baking soda and vinegar can penetrate deeper into the clog. Once the drain is clear of surface-level obstructions, you’re ready to proceed with the solution.
Next, pour 1/2 cup of baking soda directly into the shower drain, ensuring it goes as far down as possible. Baking soda is a mild alkali that acts as a natural cleaner and deodorizer. Allow it to sit in the drain for a few minutes to begin breaking down the clog. After the baking soda has been applied, slowly pour 1/2 cup of white vinegar into the drain. Vinegar is an acid, and when combined with baking soda, it creates a fizzing reaction that helps dislodge buildup and clear the drain. The chemical reaction between the two ingredients is both safe for your pipes and powerful enough to tackle many common clogs.
Once you’ve added the vinegar, cover the drain with a plug or a wet cloth to keep the reaction contained within the pipe. Let the mixture sit for 15 to 30 minutes to maximize its effectiveness. During this time, the fizzing action will work to dissolve soap scum, grease, and other debris. If you notice excess fizzing or bubbling, don’t worry—this is a sign that the reaction is working as intended. After the waiting period, remove the cover and flush the drain with hot water. The hot water helps wash away the loosened debris and ensures the drain is thoroughly cleared.
For stubborn clogs, you may need to repeat the process. Start again by pouring baking soda into the drain, followed by vinegar, and allow it to sit for another 15 to 30 minutes. Afterward, flush the drain with hot water once more. This method is gentle enough to use regularly as a preventive measure to keep your shower drain flowing smoothly. It’s also a cost-effective alternative to chemical drain cleaners, which can be harsh on pipes and harmful to the environment.
To maintain optimal drainage, consider using this baking soda and vinegar method once a month as part of your regular cleaning routine. Additionally, avoid letting hair and soap scum accumulate in the drain by using a drain cover or hair catcher. By combining this natural cleaning method with preventive measures, you can effectively lower the risk of shower drain clogs and keep your plumbing in good condition.

Apply Drain Snake Tool
To apply a drain snake tool effectively for lowering a shower drain, begin by gathering the necessary materials. You’ll need a drain snake (either manual or electric), gloves to protect your hands, and a bucket to catch any water or debris that may come out during the process. Ensure the shower area is clear of any obstructions and lay down a towel or mat to keep the area clean. If your drain snake has interchangeable tips, select the one best suited for shower drains, typically a small, flexible coil.
Next, insert the drain snake into the shower drain opening. Slowly feed the snake into the drain pipe, applying gentle pressure to navigate through the bends and curves of the plumbing. Avoid forcing the tool, as this could damage the pipes. For manual drain snakes, turn the handle clockwise to extend the snake further into the drain. If using an electric snake, follow the manufacturer’s instructions to operate it safely. The goal is to reach the clog or obstruction causing the drain to sit too high.
Once the snake encounters resistance, this indicates you’ve reached the clog. Rotate the snake handle (or use the electric function) to break up or capture the blockage. For manual snakes, continue turning the handle to coil the debris onto the snake’s corkscrew end. For electric snakes, use the machine’s mechanism to dislodge or retrieve the clog. Be patient, as it may take several attempts to fully clear the obstruction, especially if it’s stubborn or deep within the pipe.
After successfully breaking up or removing the clog, slowly retract the drain snake from the drain. Dispose of any debris caught on the snake in a trash bag, and clean the tool according to the manufacturer’s guidelines. Run hot water through the shower drain to flush out any remaining particles and ensure the drain is functioning properly. If the water flows freely and the drain sits lower, you’ve successfully completed the task.
Finally, inspect the drain for any signs of damage or lingering issues. If the drain still appears too high or water drains slowly, there may be additional clogs or underlying problems requiring professional assistance. Regular maintenance, such as using a drain cover to catch hair and debris, can prevent future clogs and keep the shower drain at the proper level. Always store your drain snake in a dry place for future use.

Install Drain Cover
Lowering a shower drain often involves adjusting the drain assembly or modifying the shower base. One effective method to achieve this is by installing a drain cover, which can help reduce the effective height of the drain without major plumbing alterations. Here’s a detailed guide on how to install a drain cover as part of the process to lower your shower drain.
Step 1: Gather the Necessary Tools and Materials
Before beginning, ensure you have all the required tools and materials. You’ll need a new drain cover specifically designed for your shower drain type (e.g., screw-on, snap-in, or drop-in), a screwdriver or wrench, plumber’s tape, and possibly silicone sealant. Check the manufacturer’s instructions for any additional requirements. If your current drain cover is damaged or incompatible with lowering the drain, purchase a replacement that sits lower or has a thinner profile.
Step 2: Remove the Existing Drain Cover
Start by removing the existing drain cover. Depending on the type, this may involve unscrewing it counterclockwise, prying it off with a flathead screwdriver, or lifting it out if it’s a drop-in style. Be gentle to avoid damaging the drain assembly. Once removed, clean the area around the drain to ensure a secure fit for the new cover. If there are any remnants of old sealant or debris, scrape them off using a putty knife or scrub with a brush.
Step 3: Prepare the New Drain Cover
Inspect the new drain cover to ensure it fits properly and sits lower than the previous one. If it has threads, wrap plumber’s tape around them to create a watertight seal. For covers that require adhesive or sealant, apply a bead of silicone sealant to the underside of the cover or the drain opening, following the manufacturer’s instructions. Ensure the cover aligns with the drain hole and sits flush with the shower base to prevent water pooling.
Step 4: Install the New Drain Cover
Carefully place the new drain cover over the shower drain. If it’s a screw-on type, tighten it clockwise using a screwdriver or wrench, but avoid over-tightening to prevent cracking. For snap-in or drop-in covers, press firmly until it locks into place or sits securely. Wipe away any excess sealant that squeezes out from the edges. Allow the sealant to cure according to the product instructions before using the shower.
Step 5: Test the Installation
Once the drain cover is installed, run water in the shower to ensure it drains properly and there are no leaks. Check that the cover sits at the desired height, effectively lowering the drain. If adjustments are needed, remove the cover, reapply sealant, and reinstall it. Regularly inspect the drain cover for signs of wear or damage and replace it as necessary to maintain proper drainage.
By installing a drain cover, you can lower the effective height of your shower drain without extensive plumbing work. This method is cost-effective and can be completed with basic tools, making it a practical solution for many homeowners.

Check & Clean P-Trap
Lowering a shower drain often involves addressing issues within the existing plumbing, and one crucial component to inspect is the P-trap. The P-trap is a curved section of pipe located beneath the drain, designed to hold water and prevent sewer gases from entering your home. Over time, it can become clogged with hair, soap scum, and debris, leading to slow drainage or blockages. Checking and cleaning the P-trap is a straightforward task that can significantly improve your shower drain’s functionality.
To begin, locate the P-trap under your shower drain. It is typically a U-shaped or curved pipe made of PVC or metal. Place a bucket or tray beneath the trap to catch any water or debris that may spill out during the process. Next, use a pipe wrench or pliers to loosen the slip nuts connecting the trap to the drainpipe and the horizontal pipe leading to the wall. Be gentle to avoid damaging the pipes or threads. Once the nuts are loosened, carefully remove the P-trap by twisting it free from the connections.
With the P-trap removed, inspect it for clogs or buildup. Common culprits include hair, soap residue, and small objects that may have gone down the drain. Use a flashlight to thoroughly examine the interior of the trap. If you notice a blockage, remove as much debris as possible by hand or with a small tool like a screwdriver or drain snake. For stubborn clogs, consider using a mixture of baking soda and vinegar or a commercial drain cleaner to break down the buildup. Allow the cleaner to sit for the recommended time before rinsing it out with hot water.
After cleaning the P-trap, reassemble it by reattaching it to the drainpipe and horizontal pipe. Tighten the slip nuts securely, but avoid over-tightening to prevent cracking the pipes. Ensure all connections are snug and properly aligned. Once the P-trap is back in place, run water through the shower drain to test for leaks and ensure proper flow. If the water drains smoothly, you’ve successfully addressed the issue.
Regular maintenance of the P-trap is essential to prevent future clogs and ensure your shower drain functions efficiently. Consider checking and cleaning the P-trap every few months, especially if you have long hair or frequently use products that can build up in the pipes. By keeping the P-trap clean, you can avoid the need for more extensive plumbing repairs and maintain optimal drainage in your shower.
