Gather the Necessary Tools and Materials

Before you begin the installation process, it is essential to gather all the tools and materials required for the task. Here’s a list of what you will need:

  • Pencil and measuring tape
  • Chalk line
  • Angle grinder with a diamond blade
  • Hammer and chisel
  • Trowel and finishing tools
  • Epoxy or waterproofing membrane
  • Linear drain kit with installation hardware
  • PVC or ABS pipes and fittings for connecting to the plumbing system
  • Pipe cutter or hacksaw
  • PVC cement or solvent weld glue

Prepare the Concrete Floor

The first step in installing a linear shower drain in a concrete floor is to prepare the floor for the drain installation. Follow these steps:

  1. Locate the Drain Position

  2. Using a pencil and measuring tape, determine the precise location of the linear drain in your shower area. Consider the slope of the floor and the desired position for the drain.

  3. Mark the Drain Position

  4. Use a chalk line to mark the exact position of the linear drain on the concrete floor. Ensure that the drain aligns with the slope and the desired placement.

  5. Cut the Concrete

  6. With an angle grinder equipped with a diamond blade, carefully cut along the chalk line to create a rectangular hole in the concrete. Be cautious and wear safety glasses and a dust mask during this step.

  7. Remove the Concrete

  8. Use a hammer and chisel to break away the concrete within the marked area. Continue until you have removed enough depth to accommodate the linear drain and its height. Remember to maintain a smooth and level surface.

Position and Install the Linear Drain

Once the concrete floor is prepared, it is time to position and install the linear shower drain. Follow these steps:

  1. Check the Drain Manufacturer’s Instructions

  2. Begin by reviewing the installation instructions provided by the manufacturer of your linear drain. Familiarize yourself with the specific requirements and recommendations for your particular drain model.

  3. Set the Drain Body

  4. Place the drain body in the prepared hole and ensure that it sits level with the surrounding floor. Use shims if necessary to achieve a level position.

  5. Secure the Drain Body

  6. Secure the drain body to the concrete floor using the provided installation hardware. This typically involves screwing or clamping the drain body down. Follow the manufacturer’s instructions carefully.

  7. Attach the Grate

  8. Attach the linear grate to the drain body, ensuring a secure fit. Some grates may require screws or clips for installation. Refer to the manufacturer’s instructions for the specific method.

Connect the Drain to the Plumbing System

Connecting the linear shower drain to the plumbing system is a critical step in the installation process. Here’s what you need to do:

  1. Measure and Cut the Drain Pipe

  2. Measure and cut a section of PVC or ABS pipe to connect the linear drain to the existing plumbing system. Use a pipe cutter or hacksaw to achieve a clean and precise cut.

  3. Apply Cement or Solvent Weld Glue

  4. Apply PVC cement or solvent weld glue to both the drain outlet and the cut end of the drain pipe. Ensure that it is evenly distributed and covers the entire surface.

  5. Connect the Drain Pipe

  6. Insert the drain pipe into the drain outlet and twist it slightly to ensure a proper seal. Hold it in place for a few seconds to allow the cement or glue to set.

  7. Connect to the Plumbing System

  8. Connect the other end of the drain pipe to the existing plumbing system, making sure to use the appropriate fittings and connectors. Follow the local building codes and plumbing regulations for proper installation.

Waterproof the Shower Area

Waterproofing the shower area is essential to prevent water damage and leaks. Follow these steps to ensure a watertight enclosure:

  1. Apply a Waterproofing Membrane

  2. Use an epoxy or waterproofing membrane to seal the area surrounding the linear shower drain. Apply the product according to the manufacturer’s instructions, covering the entire floor area.

  3. Seal Joints and Corners

  4. Pay special attention to the joints and corners of the shower area. Use a trowel or a sealant gun to seal all the gaps and create a seamless membrane surface.

  5. Allow the Waterproofing to Cure

  6. Allow the waterproofing membrane to cure and dry completely before proceeding with the installation of tiles or other flooring materials. Follow the recommended drying time provided by the manufacturer.

Test and Inspect the Drain

Before completing the installation process, it is essential to test and inspect the linear shower drain to ensure its functionality. Here’s what you should do:

  1. Fill the Drain with Water

  2. Pour a sufficient amount of water into the shower area to test the drain’s capacity. Ensure that the water flows freely into the drain and that there are no leakage or blockage issues.

  3. Inspect the Drain Edges

  4. Check the edges of the drain, both inside and outside the shower area, for any signs of water leaks or seepage. Address any issues promptly before proceeding.

  5. Verify Proper Drainage

  6. Observe the speed and efficiency at which the water drains from the shower area. Ensure that it flows directly into the linear drain without pooling or backing up.


Installing a linear shower drain in a concrete floor is a precise and detailed process. By following the steps outlined in this guide, you can achieve a professional and functional installation. Remember to consult the manufacturer’s instructions and adhere to local building codes and regulations. A well-installed linear shower drain will not only enhance the aesthetic appeal of your bathroom but also provide efficient drainage and prevent potential water damage.
