Prepare The Concrete Floor
To build a shower pan on a concrete floor, you first need to ensure that the floor is properly prepared. This includes cleaning the surface and filling any cracks that may be present.
Clean The Floor
Before you begin any work on the shower pan, take the time to thoroughly clean the concrete floor. Removing any dirt, dust, or debris will ensure that the new shower pan adheres properly to the surface.
Here are the steps to clean the floor:
- Sweep the floor to remove any loose dirt or debris.
- Use a solution of warm water and mild detergent to mop the floor, paying special attention to any areas that may be particularly dirty.
- Rinse the floor thoroughly with clean water to remove any soap residue.
- Allow the floor to dry completely before moving on to the next step.
Fill And Level Any Cracks
After cleaning the floor, it’s essential to fill and level any cracks that may be present. This step will ensure that the shower pan sits flat and prevents any water leakage.
Follow these instructions to fill and level cracks:

- Fill the cracks with a concrete patching compound, following the manufacturer’s instructions.
- Smooth the compound using a trowel, ensuring that it is level with the surrounding floor surface.
- Allow the compound to dry completely before proceeding.
- If necessary, sand down any uneven areas to create a smooth and even surface.
Install The Shower Drain
Installing the shower drain is an essential step in building a shower pan on a concrete floor. This process involves locating and marking the drain position, cutting and removing the concrete around the drain, and finally, attaching the drain assembly. Let’s dive into each step.
Locate And Mark The Drain Position
To begin, you need to locate and mark the position where the shower drain will be installed. This is typically done during the initial planning phase of your shower pan construction. Make sure you position the drain in the center of the shower floor to ensure proper drainage. Once you’ve determined the exact spot, mark it using a pencil or any other suitable marking tool.
Cut And Remove The Concrete Around The Drain
Next, cut and remove the concrete around the drain marked area. Use a suitable concrete saw or a hammer and chisel to carefully cut through the concrete surface. Take caution to avoid damaging any pipes or plumbing lines underneath. Once the concrete is cut, use a pry bar or any other appropriate tool to remove the concrete pieces. Ensure that you completely clear the area around the drain so that the drain assembly can be installed properly.
Attach The Drain Assembly
Now it’s time to attach the drain assembly. Begin by placing the rubber gasket or the waterproof membrane over the drain hole. This will help create a watertight seal. Next, insert the drain body into the hole, making sure it fits snugly. Finally, secure the drain body in place using the provided screws or locking mechanism.
It’s important to double-check that the drain assembly is tightly secured and level with the shower floor. Any gaps or loose fittings can lead to leakage issues down the line.
That’s it! You’ve successfully installed the shower drain on your concrete floor. The shower pan construction can now progress to the next steps, such as waterproofing and tiling. Remember to follow the manufacturer’s instructions for the specific drain kit you’re using, as the installation process might vary slightly.

- Spread a layer of the mixed mortar evenly across the concrete floor using a trowel. Make sure the mortar is at least 1 inch thick.
- Smooth out the mortar bed with the flat side of the trowel, pressing down gently to remove any air bubbles and create a level surface.
Trowel And Smooth The Mortar
Once you’ve created the mortar bed, it’s time to trowel and smooth the surface to ensure a solid foundation for your shower pan. Follow these steps:
- Hold the trowel at a 45-degree angle and use it to smooth out any ridges or uneven areas in the mortar bed.
- Continue to trowel the entire surface of the mortar bed, working from one side to the other in smooth, even strokes.
- Check for any remaining imperfections and use the trowel to level them out. The surface should be smooth and even.
Install Waterproofing Membrane
To prevent water damage and leaks, it’s essential to install a waterproofing membrane over the mortar bed. This will create a barrier that keeps water from seeping into the concrete. Follow these steps:
- Measure and cut the waterproofing membrane to fit the size of your shower pan. Leave an overhang of a few inches on all sides.
- Apply a layer of thin-set mortar to the surface of the mortar bed using a trowel.
- Place the waterproofing membrane onto the mortar bed, starting at one corner and working your way across. Smooth out any wrinkles or air bubbles as you go.
- Secure the membrane to the concrete floor by pressing it down firmly with a rubber float or trowel.
- Trim any excess membrane with a utility knife, leaving a slight overhang along the edges to ensure complete coverage.
By following these steps, you’ll be well on your way to building a sturdy and waterproof shower pan on a concrete floor. Remember to take your time and ensure each step is done correctly for the best results.
