What Will You Need?
Before getting started, gathering all the necessary tools and materials is crucial. Here is a basic list of what you will need:
- Measuring tape
- Level
- Chalk line
- Waterproofing membrane or sheet

Once you have everything on hand, it’s time to start planning and preparing the floor for your new curbless shower!
10 Easy Steps on How to Build a Curbless Shower on Concrete
Step 1: Plan and Measure
Begin by carefully planning the layout of your curbless shower. Consider the dimensions of the space, the location of plumbing, and how the shower will connect to the existing drainage system.
Use your measuring tape to outline the shower area on the concrete floor, ensuring that you account for the slope required for proper drainage. A slope of approximately 1% to 2% is ideal, directing water towards the drain. Mark your intended boundary with a chalk line for clarity.
This step is vital, as accurate measurements will determine the overall success of your installation. Take your time to double-check your measurements, as adjustments can become more challenging once work begins. With a well-planned layout and precise measurements, you’ll set a strong foundation for the following steps in creating your curbless shower.
Step 2: Prepare the Floor
Once you have your layout marked, it’s time to prepare the concrete floor. Clean the area thoroughly to remove any dust, debris, or previous coatings. Then, check the level of the concrete; if there are any high spots, you may need to grind them down to ensure a flat surface.
After providing the floor is level, apply a waterproofing membrane or sheet that extends beyond the outlined shower area. This step is essential for preventing moisture from penetrating the concrete and causing damage over time. Follow the manufacturer’s instructions for application and allow sufficient drying time before proceeding to the next step.
Step 3: Install the Drain
Next, you’ll need to install the drain assembly. Choose a linear drain suitable for curbless installations, as it allows for better water flow and aesthetics. Position the drain at the lowest point of your shower area to ensure proper drainage.
This might involve cutting into the concrete slightly to create a recess for the drain if necessary. Use a level to ensure it’s installed correctly and slope the surrounding area towards the drain, maintaining the ideal slope of 1% to 2%. Secure the drain in place according to the manufacturer’s instructions, and ensure it is watertight to avoid leaks.
Step 4: Create the Sloping Base
You’ll need to create a sloped base using a mortar bed to achieve the required slope towards the drain. Mix the appropriate mortar or concrete according to the manufacturer’s guidelines.
Apply the mixture starting from the farthest point of the shower, sloping it downwards towards the drain. Use a float to smooth out the surface while checking the slope frequently with your level. Once the base is shaped correctly, let it cure completely, typically for at least 24 hours.
Step 5: Apply Tile Adhesive
With your sloping base fully cured, the next step involves applying tile adhesive to prepare for tiling. Begin by selecting a high-quality tile adhesive compatible with your chosen tiles and the waterproofing membrane you’ve installed.
Using a notched trowel, spread the adhesive evenly across a small section of the sloped base, starting from the farthest side and working your way toward the drain. Ensure that you use the appropriate notch size for the tiles you’re using to achieve a secure bond.
Be mindful of the open time of the adhesive; this refers to the amount of time you have to lay the tiles before the adhesive begins to set. To ensure the best adhesion, it’s advisable to apply the glue in small sections so that it doesn’t dry out before you can lay the tiles.
As you begin placing the tiles, follow your desired pattern, pressing each tile firmly into the adhesive and ensuring no air pockets are beneath. Use spacers between the tiles to maintain even grout lines, and periodically check that the tiles are level, adjusting as necessary before the adhesive sets.
Step 6: Tile Installation
Once all the tiles are laid and the adhesive has set, it’s time to move on to grouting. Begin by removing the tile spacers you used between the tiles, making sure not to disturb the tiles themselves.
Prepare your grout according to the manufacturer’s instructions, mixing it to a smooth, consistent texture. Using a grout float, spread the grout over the tiles at a 45-degree angle to ensure it fills all the joints. After applying the grout, use the edge of the float to scrape away any excess grout from the tile surfaces.
Step 7: Clean the Tiles
After allowing the grout to set for about 15-30 minutes, cleaning the tiles to remove any grout haze is crucial. Dampen a soft sponge in clean water and gently wipe the tile surfaces to reveal their shine.
Be careful not to dislodge any grout from the joints while cleaning. Rinse the sponge frequently until the tiles are clean and clear of haze. Allow the grout to cure fully, which may take 24 hours or as indicated by the manufacturer’s instructions.
Step 8: Seal the Grout
Consider sealing the grout once it has cured completely to ensure durability and water resistance. Apply a grout sealer using a small brush or applicator to cover all grout lines thoroughly. This step is essential, as it prevents moisture penetration and helps maintain the grout’s integrity over time. Follow the sealer manufacturer’s instructions for best results, including any recommended drying times.
Step 9: Install Shower Fixtures
Installing your shower fixtures is the final step in completing your curbless shower project. Begin by selecting fixtures that complement your design while offering functionality and ease of use. Common fixtures include a showerhead, diverter, and control valve, which should be compatible with your existing plumbing.
First, identify your showerhead’s desired height and mark the installation location. If necessary, adjust any plumbing lines to accommodate the new fixtures. Carefully follow the manufacturer’s instructions for each component during installation to ensure proper fitting and functionality.
Once all components are securely installed, turn the water supply back on and check for leaks. It’s essential to do a thorough inspection of the connections around the fixtures, as this helps prevent potential water damage in the future. After confirming everything is leak-free, complete the look by installing trim pieces and ensuring all controls operate smoothly.
Finally, test your shower to ensure the water flow, temperature, and pressure meet your expectations.
Step 10: Final Inspection and Cleanup
After installing your curbless shower, conducting a thorough final inspection is essential. Check all seams, joints, and fixtures to ensure everything is secure and functioning as intended. Look for imperfections in the tile work, grout lines, or fixtures, making necessary adjustments or touch-ups.
Once you are satisfied with the installation, proceed with cleanup. Safely dispose of your project’s leftover materials, debris, and packaging. Wipe down surfaces and tools to remove adhesive, grout, or dirt, leaving your new shower area clean and ready for use. Finally, take a moment to appreciate your handiwork; a well-executed curbless shower intallation not only enhances the aesthetic of your bathroom but also adds considerable value to your home.
You can successfully install a curbless shower in your bathroom by following these steps and carefully following the manufacturer’s instructions. Remember to pay close attention to detail and take the time to properly prepare and waterproof your shower base for the best results.
