Removing the Old Drain Assembly
Before you begin removing the old drain assembly from your MAAX shower, ensure you have the necessary tools: a screwdriver, pliers, a putty knife, and possibly a drain key or wrench. Start by turning off the water supply to the shower to prevent any accidental spills. Next, remove the shower drain cover by unscrewing it or prying it off gently with a putty knife, depending on the type of cover installed. Be cautious not to damage the surrounding shower floor during this step.
Once the drain cover is removed, inspect the drain assembly for any visible screws or fasteners holding it in place. If there are screws, use the appropriate screwdriver to remove them carefully. Some MAAX shower drains may have a threaded collar or locking mechanism beneath the cover. If so, use pliers or a drain key to loosen and unscrew the collar counterclockwise. Apply steady pressure and ensure you have a firm grip to avoid slipping.
After loosening the collar or removing the screws, attempt to lift the old drain assembly out of the shower pan. If it feels stuck, avoid forcing it, as this could damage the shower base. Instead, check for any remaining debris, sealant, or caulking that might be holding it in place. Use the putty knife to gently scrape away any obstructions around the edges of the drain assembly. Be thorough but gentle to preserve the integrity of the shower pan.
In some cases, the drain assembly may be sealed with plumber’s putty or silicone. If this is the case, use a utility knife or putty knife to carefully cut through the sealant. Work your way around the drain assembly, loosening the seal gradually. Once the sealant is removed, try lifting the assembly again. If it still resists, lightly tap around the edges with a mallet and a block of wood to dislodge it without causing damage.
Finally, with the old drain assembly removed, inspect the drain opening for any remaining debris, old sealant, or damage. Clean the area thoroughly to ensure a proper fit for the new drain assembly. If you notice any cracks or damage to the shower pan, address these issues before proceeding with the installation of the new drain. Properly removing the old assembly sets the foundation for a successful and leak-free installation.

Installing the New Drain Base
Before installing the new drain base for your MAAX shower, ensure you have the necessary tools and materials: a new drain base, plumber’s putty or silicone sealant, a screwdriver, a wrench, and a utility knife. Begin by removing the old drain base if it’s still in place. Use a screwdriver to loosen any screws holding it down and carefully lift it out. Clean the area thoroughly to remove any debris, old sealant, or residue, ensuring a smooth surface for the new base. Inspect the shower pan or floor to confirm it’s in good condition and ready for installation.
Next, prepare the new drain base by applying a bead of plumber’s putty or silicone sealant around the underside of its flange. This creates a watertight seal between the base and the shower pan. Center the drain base over the existing drain hole, pressing it firmly into place to ensure the sealant adheres properly. Double-check that the base is level and aligned correctly, as any misalignment can lead to water pooling or drainage issues. Allow the sealant to set according to the manufacturer’s instructions before proceeding.
Once the drain base is securely in place, attach the strainer or cover plate provided with the unit. Secure it using the screws included in the kit, ensuring it’s tight enough to prevent movement but not so tight that it damages the base. Test the strainer to ensure it fits snugly and functions properly, allowing water to flow freely while catching debris. If the strainer feels loose or unstable, adjust the screws or add additional sealant as needed.
After installing the strainer, connect the drain pipe to the base. Position the pipe directly beneath the drain outlet and secure it using a wrench to tighten the coupling nut. Ensure the connection is tight and leak-free by running water through the drain and checking for any signs of leakage. If leaks are detected, tighten the connection further or apply additional sealant around the joint.
Finally, test the entire assembly by running water through the shower and observing the drainage. Ensure water flows smoothly without pooling or backups. Inspect the area around the drain base for any signs of leaks, addressing any issues immediately. Once everything is functioning correctly, clean the area around the drain to remove any excess sealant or debris, leaving your new MAAX shower drain base ready for regular use.

Sealing and Waterproofing the Drain
When sealing and waterproofing the drain of a MAAX shower, the first critical step is to ensure the drain assembly is properly installed and aligned. Begin by placing the drain body into the pre-cut hole in the shower base, ensuring it sits flush with the surface. Secure the drain body from below using the provided screws or bolts, tightening them just enough to hold it firmly in place without over-torquing. Proper alignment is essential to prevent leaks and ensure effective waterproofing.
Next, apply a high-quality silicone sealant or plumber’s putty around the top edge of the drain body where it meets the shower base. Silicone sealant is often preferred for its durability and water resistance. Use a caulking gun to apply a continuous bead of sealant, ensuring it adheres evenly to both the drain and the shower surface. Smooth the sealant with a damp finger or a sealant tool to create a clean, watertight seal. Allow the sealant to cure according to the manufacturer’s instructions before proceeding.
After sealing the top of the drain, focus on the underside connections. Attach the drain pipe to the drain body using a threaded adapter or PVC piping, depending on your plumbing setup. Secure the connection with threaded fittings or solvent cement for PVC pipes. Wrap the threads with Teflon tape or apply pipe dope to ensure a tight, leak-free joint. Double-check that all connections are secure and properly aligned to prevent water from escaping into the subfloor.
To further enhance waterproofing, consider installing a waterproof membrane or shower liner beneath the shower base. This additional layer acts as a secondary barrier against water intrusion, especially in areas prone to leaks. Ensure the membrane extends up the walls and overlaps with the drain assembly for comprehensive protection. Follow the manufacturer’s guidelines for installing the membrane, paying close attention to seams and corners.
Finally, test the drain for leaks before completing the installation. Fill the shower base with water and let it sit for several hours, checking for any signs of leakage around the drain or plumbing connections. If leaks are detected, drain the water, disassemble the necessary components, and reapply sealant or tighten connections as needed. Once the drain is confirmed to be leak-free, proceed with tiling or finishing the shower area, confident that the drain is properly sealed and waterproofed.

Testing for Leaks and Final Adjustments
Once the MAAX shower drain is installed and connected to the plumbing system, it’s crucial to test for leaks and make final adjustments to ensure everything functions properly. Begin by turning on the water supply and allowing water to flow into the shower pan. Observe the drain connections, including the PVC or ABS pipes, for any signs of moisture or dripping. Pay close attention to the joints where the drain body meets the trap and where the trap connects to the main drain line. Even a small leak can lead to significant water damage over time, so thorough inspection is essential.
Next, fill the shower pan with several inches of water and let it sit for at least 15–20 minutes. This simulates a full shower use and helps identify leaks that might not be immediately apparent. Inspect the underside of the shower pan, the drain assembly, and the surrounding floor or subfloor for any water accumulation. If you notice any leaks, turn off the water supply and disassemble the problematic joint. Clean the area, reapply plumber’s tape or sealant as needed, and reattach the components securely. Repeat the test until no leaks are detected.
After confirming there are no leaks, check the drain’s functionality by releasing the water from the shower pan. Ensure the water flows smoothly and quickly through the drain without backing up or pooling. If the drain seems slow, inspect the trap and drain lines for obstructions or improper alignment. Adjust the angle of the drain pipes if necessary to ensure proper slope for efficient drainage. A well-sloped drain prevents standing water and reduces the risk of clogs.
Finally, make any necessary adjustments to the shower drain cover or grate to ensure it sits flush with the shower floor. Tighten any screws or fasteners securely, but avoid over-tightening to prevent cracking the drain material. Wipe down the area to remove excess sealant or debris, leaving the installation clean and professional. Once all adjustments are complete, run water through the shower again to confirm everything is functioning correctly. Proper testing and final adjustments are key to a leak-free and long-lasting MAAX shower drain installation.
