1. Gather the Necessary Tools and Materials

Before you begin the installation process, make sure you have all the tools and materials needed for the job. Here is a checklist of what you will need:

• Shower drain kit
• Concrete mix
• Measuring tape
• Level
• Hacksaw
• Trowel
• Bucket
• Drill
• Plastic sheeting
• PVC glue
• Plumber’s putty

2. Determine the Placement of the Drain

The first step in installing a drain for a shower in concrete is to determine the placement of the drain. This will depend on the size and layout of your shower, as well as any specific requirements outlined in your local building codes.

Using the measuring tape, determine the center point of the shower and mark it on the concrete floor. This is where the drain will be placed. Take into consideration the position of the shower walls and the slope of the floor for proper drainage.

3. Prepare the Concrete for Drain Installation

Before installing the drain, you need to prepare the concrete floor to ensure a secure and stable installation. This involves creating a recessed area for the drain to sit in.

Start by covering the shower floor with plastic sheeting to protect it from any debris or splatters. Then, using a drill and a masonry bit, create pilot holes around the perimeter of the marked center point. These holes will allow you to insert a hacksaw blade to cut out the recessed area.

Once the pilot holes are created, carefully cut along the marked perimeter with the hacksaw. Take your time and make sure the edges are clean and smooth. Remove any loose debris and clean the area thoroughly before proceeding.

4. Install the Drain Base

Now it’s time to install the drain base, which will provide the support for the drain and help create a watertight seal. The drain base typically comes as part of a shower drain kit, which includes all the necessary components for installation.

Apply plumber’s putty or silicone sealant around the bottom perimeter of the drain base. This will create a waterproof seal between the drain and the concrete floor. Place the drain base into the recessed area and press it firmly into place. Ensure that it is level and centered within the marked center point. Use a level to double-check the alignment and make any necessary adjustments.

Once the drain base is in place, follow the manufacturer’s instructions to secure it to the concrete floor. This may involve using screws or adhesive, depending on the specific drain kit you are using. Make sure the drain base is securely fastened and does not move.

5. Connect the Drain Pipe

Now that the drain base is installed, it’s time to connect the drain pipe. This pipe will carry the water from the shower to the plumbing system, ensuring proper drainage.

Measure and cut the drain pipe according to the manufacturer’s instructions, ensuring a proper fit. Apply PVC glue to the inside of the drain base and the outside of the drain pipe, then connect the two. Twist the pipe slightly to ensure a tight and secure connection.

It’s important to double-check the alignment of the drain pipe and make sure it has the correct slope for proper drainage. Use a level to ensure the pipe is angled slightly towards the main plumbing pipe to encourage water flow.

6. Pour and Level the Concrete

With the drain base and pipe securely in place, it’s time to pour and level the concrete around the drain. This will create the shower floor and provide a stable surface for tile or other finishing materials.

Following the instructions on the concrete mix, prepare the concrete in a bucket according to the correct proportions. The consistency of the mix should be thick but pourable. Carefully pour the concrete mixture around the drain base, ensuring that it completely fills the recessed area and covers the drain pipe.

Smooth the concrete surface with a trowel, making sure it is level and evenly distributed. Use the trowel to create a slight slope towards the drain, which will assist with water drainage. Continue to work the concrete until you achieve a smooth and even finish.

7. Test the Drain for Proper Functioning

Once the poured concrete has set, it’s important to test the drain for proper functioning before proceeding with any further construction. This will help identify any potential issues or leaks that need to be addressed.

Remove the plastic sheeting covering the shower floor and inspect the drain area. Run water into the shower to simulate normal usage and observe how the water flows into the drain. Check for any leaks or pooling of water around the drain base.

If you notice any issues, such as slow drainage or leaks, you may need to adjust the slope of the concrete or reseal the drain base. It’s important to address these issues promptly to prevent any water damage or mold growth.

8. Finish the Shower Floor

Once the drain is tested and functioning properly, you can proceed with finishing the shower floor according to your desired design. This may involve tiling, applying a waterproofing membrane, or any other finishing materials of your choice.

Follow the manufacturer’s instructions for applying and installing the chosen materials to ensure a durable and waterproof shower floor. Take your time and pay attention to detail to achieve the desired results.

Frequently Asked Questions (FAQ)

Q: Can I install a drain for a shower in an existing concrete floor?

A: Yes, it is possible to install a drain for a shower in an existing concrete floor. However, the process may be more challenging and time-consuming, as you will need to remove a section of the concrete to create a recessed area for the drain. It is recommended to consult with a professional for this type of installation.

Q: How long does it take for the poured concrete to set?

A: The drying time for poured concrete can vary depending on factors such as temperature and humidity. On average, it may take 24-48 hours for the concrete to fully set. It is important to allow sufficient drying time before moving forward with any further construction or finishing.

Q: Can I use a shower drain kit with a different drain style?

A: It is generally recommended to use a shower drain kit that matches the specific drain style you have chosen for your shower. Different drain styles may have varying sizes, shapes, or configurations that require compatibility with the drain base and pipe. Using a mismatched kit may result in leaks or improper functioning of the drain.

Q: Do I need to apply a waterproofing membrane before tiling the shower floor?

A: Applying a waterproofing membrane is highly recommended before tiling the shower floor. This membrane provides an additional layer of protection against water damage and helps prevent moisture from seeping into the underlying structure. Follow the manufacturer’s instructions for proper application and ensure complete coverage of the shower floor.

By following these steps and taking the necessary precautions, you can successfully install a drain for a shower in concrete. Remember to consult local building codes and guidelines to ensure compliance and hire a professional if you are uncertain about any part of the installation process. With the right tools and techniques, you can achieve a functional and aesthetically pleasing shower that will provide years of reliable use.
