Removing the Old Drain
Before you begin removing the old shower drain, ensure you have the necessary tools and safety gear. You’ll need a reciprocating saw or rotary hammer with a masonry blade, a cold chisel, a hammer, safety goggles, gloves, and a dust mask. Start by turning off the water supply to the shower and removing any remaining water from the drain using a wet-dry vacuum or sponge. Cover the surrounding area with a drop cloth or plastic sheeting to catch debris and minimize cleanup. Once prepared, carefully inspect the drain assembly to identify any screws or fasteners holding the drain cover in place. Remove these using a screwdriver or appropriate tool, then lift the drain cover out of the way.
With the drain cover removed, focus on the drain body embedded in the concrete. Use the reciprocating saw or rotary hammer with a masonry blade to cut through the caulk or sealant around the drain’s edge. Work slowly and carefully to avoid damaging the surrounding concrete. Once the sealant is cut, attempt to loosen the drain body by prying it gently with a flat bar or screwdriver. If the drain is stubborn, you may need to chip away the concrete directly around the drain using a cold chisel and hammer. Strike the chisel at a slight angle to undercut the concrete and free the drain body. Be patient, as this step can be time-consuming.
If the drain body is still difficult to remove, consider using a reciprocating saw with a metal-cutting blade to carefully cut through the drain’s flange or body. This will allow you to separate the drain from the pipe below. Ensure you do not damage the drain pipe during this process, as it will need to remain intact for the new drain installation. Once the drain body is free, lift it out of the hole, taking care not to disturb the plumbing connections below.
After removing the drain body, inspect the hole in the concrete floor. Use the cold chisel and hammer to clean up any rough edges or remaining debris. If the hole is larger than the new drain assembly, you may need to patch the concrete with a quick-setting mortar or concrete patch mix. Ensure the area is clean and free of loose material before proceeding to the next steps of installing the new drain.
Finally, check the condition of the drain pipe and plumbing connections. If the pipe is damaged or corroded, it may need to be repaired or replaced before installing the new drain. Use a flashlight to inspect the pipe thoroughly, and address any issues to ensure a proper fit for the new drain assembly. With the old drain completely removed and the area prepared, you’re ready to move on to installing the new shower drain.

Cutting Concrete for New Drain
Replacing a shower drain in a concrete floor requires careful planning and execution, especially when it comes to cutting the concrete to install the new drain. The first step is to mark the area where the new drain will be located. Use the existing drain as a reference point, but ensure the new drain aligns with the shower’s slope for proper water drainage. Measure and mark the dimensions of the new drain opening, typically a square or circle, depending on the drain kit. Double-check the measurements to avoid errors, as cutting concrete is irreversible.
Once the area is marked, prepare the workspace for cutting. Clear the shower area of any debris or obstacles, and lay down a drop cloth or plastic sheeting to catch concrete dust. Wear appropriate safety gear, including safety goggles, a dust mask, and ear protection, as concrete cutting generates significant dust and noise. If the shower is in an enclosed space, ensure proper ventilation to disperse dust. It’s also a good idea to inform household members to avoid the area during this process.
Next, choose the right tool for cutting the concrete. A concrete saw with a diamond blade is the most effective tool for this task. For smaller or tighter spaces, a rotary hammer with a masonry bit or an angle grinder with a diamond blade can be used, though these tools may require more time and effort. Ensure the blade or bit is designed for cutting concrete to achieve clean, precise cuts. Secure the concrete saw’s guide along the marked lines to maintain accuracy during cutting.
Begin cutting the concrete along the marked lines, following the outline of the new drain opening. If using a concrete saw, move the blade steadily along the guide, applying consistent pressure without forcing the tool. For circular cuts, start by drilling holes at the corners of the marked area to allow the blade to enter the concrete, then connect the holes with straight cuts. Keep the blade cool by spraying water on it intermittently, but be cautious not to create a slippery surface. Take breaks as needed to prevent overheating the blade or the concrete.
After completing the cuts, remove the cut-out concrete section using a pry bar or chisel. Be careful not to damage the surrounding concrete or underlying plumbing. Clean the area thoroughly, removing all debris and dust, as any leftover particles can interfere with the drain installation. Once the area is clean, inspect the opening to ensure it matches the dimensions of the new drain. If adjustments are needed, use a chisel or grinder to refine the edges before proceeding with the drain installation.

Installing the New Drain
Before installing the new shower drain, ensure the old drain has been completely removed and the area is clean and free of debris. Begin by preparing the new drain assembly according to the manufacturer’s instructions. Typically, this involves attaching the drain body to the strainer or cover plate. Apply a bead of silicone caulk or plumber’s putty around the underside of the drain flange to create a watertight seal when it is inserted into the drain hole. Carefully position the new drain assembly into the hole, ensuring it sits flush with the concrete floor. Use a level to confirm that the drain is perfectly horizontal, as improper alignment can lead to water pooling or drainage issues.
Next, secure the drain in place using the provided screws or bolts. Tighten them evenly to avoid warping the drain flange. If the drain assembly includes a compression gasket or sealing ring, ensure it is properly seated against the concrete to prevent leaks. For added stability, some drains may require anchoring with a concrete anchor or epoxy, especially in high-traffic areas like showers. Follow the manufacturer’s guidelines for any additional securing methods. Once the drain is securely fastened, allow any adhesives or sealants to cure as recommended before proceeding.
With the drain in place, connect the drain pipe to the plumbing system. Measure and cut the PVC or ABS pipe to the appropriate length, ensuring a proper fit. Use a coupling or adapter if necessary to join the new pipe to the existing plumbing. Apply primer and solvent cement to the pipe ends and fittings, then quickly assemble the joint, twisting it slightly to ensure an even spread of cement. Wipe away any excess cement with a rag. Double-check that all connections are tight and aligned to prevent leaks.
After the plumbing connections are complete, test the drain for proper functionality. Pour water into the shower area and observe how it flows into the drain. Ensure there are no clogs or obstructions and that the water drains efficiently. If the drain includes a removable strainer or cover, install it according to the manufacturer’s instructions. This component not only enhances the appearance but also prevents hair and debris from entering the drain.
Finally, integrate the new drain into the shower floor finish. If the shower floor is tiled, carefully cut and fit tiles around the drain, ensuring they are level with the drain’s top surface. Use a waterproof tile adhesive and grout to secure the tiles and seal the joints. For non-tiled floors, apply a waterproof coating or membrane around the drain to protect the concrete from moisture damage. Allow all materials to cure fully before using the shower to ensure a durable and leak-free installation.

Sealing and Testing the Drain
Once the new shower drain is installed in the concrete floor, the next critical step is sealing and testing it to ensure a watertight and durable installation. Begin by applying a high-quality waterproof sealant around the edges of the drain assembly where it meets the concrete. Use a sealant specifically designed for wet environments, such as silicone or polyurethane-based products, to create a robust barrier against moisture infiltration. Apply the sealant generously, ensuring it adheres well to both the drain flange and the surrounding concrete surface. Smooth the sealant with a caulking tool or your finger (wearing a glove) to eliminate gaps and create a uniform seal. Allow the sealant to cure fully according to the manufacturer’s instructions before proceeding.
After sealing, it’s essential to test the drain for leaks to prevent future water damage. Start by plugging the drain with a rubber stopper or tape to prevent water from escaping. Fill the shower area with water to a depth of at least 2 inches, ensuring the water covers the entire drain assembly and surrounding sealant. Let the water sit for a minimum of 24 hours, periodically checking for any signs of leakage in the area below the shower, such as the ceiling or floor of the room directly beneath. If no leaks are detected, carefully remove the water and proceed with tiling or finishing the shower floor.
If a leak is identified during the test, drain the water and inspect the sealant and drain assembly for gaps or imperfections. Reapply sealant to any areas where water may be seeping through, ensuring complete coverage. Repeat the water test after the new sealant has cured to confirm the issue has been resolved. It’s crucial to address any leaks immediately to avoid long-term damage to the concrete slab or surrounding structures.
For added protection, consider applying a waterproof membrane over the entire shower floor and up the walls before tiling. This membrane acts as a secondary barrier against water penetration, further safeguarding the concrete floor. Ensure the membrane is compatible with the sealant and follows the manufacturer’s application guidelines. Properly sealing and testing the drain not only ensures the longevity of the shower but also prevents costly repairs due to water damage in the future.
Finally, once the drain is confirmed to be leak-free, proceed with the final steps of your shower installation, such as tiling and grouting. Regularly inspect the drain and sealant over time, especially after heavy use or if you notice any signs of wear. Maintaining a watertight seal around the shower drain is key to preserving the integrity of the concrete floor and the overall functionality of your shower.
