AvatarByJoshua Wilkinson Bathroom Plumbing


Transforming your shower into a sleek, modern oasis can be as simple as installing a linear drain. This innovative drainage solution not only enhances the aesthetic appeal of your bathroom but also improves functionality by providing efficient water flow and easy maintenance. If you’re considering a bathroom remodel or simply looking to upgrade your shower, understanding how to install a linear drain is essential. This guide will walk you through the process, ensuring you have the knowledge and confidence to tackle this DIY project with ease.

Linear drains are becoming increasingly popular for their minimalist design and versatility in various shower layouts. Unlike traditional round drains, linear drains offer a streamlined look and can be positioned along the wall or in the center of the shower floor, allowing for greater design flexibility. They effectively channel water away from the shower area, reducing the risk of standing water and enhancing overall hygiene.

Before diving into the installation process, it’s important to familiarize yourself with the necessary tools and materials. Proper planning and preparation can make all the difference, ensuring a smooth installation that not only meets your aesthetic goals but also adheres to plumbing regulations. Whether you’re a seasoned DIY enthusiast or a first-time homeowner, this guide will equip you with the essential steps to successfully install a linear drain in your shower.

Preparing the Shower Area

Before installing a linear drain, it is essential to prepare the shower area adequately. This involves ensuring that the subfloor is level and properly sloped towards the drain.

  • Remove any existing flooring and tiles.
  • Inspect the subfloor for damage; replace or repair as necessary.
  • Clean the area thoroughly to eliminate dust and debris.

To create the appropriate slope, a minimum of 1/4 inch per foot towards the drain is recommended. Use a level and a straightedge to check that the subfloor meets this requirement. If adjustments are needed, consider using a self-leveling compound to achieve the desired slope.

Choosing the Right Linear Drain

Selecting the appropriate linear drain is crucial for both functionality and aesthetics. Factors to consider include:

  • Length: Choose a drain that fits the width of your shower.
  • Material: Options typically include stainless steel, PVC, or polymer.
  • Grate Style: Various designs are available, from minimalist to decorative patterns.
  • Flow Rate: Ensure the drain can handle the water flow from your showerhead.

Here’s a comparison of common materials used for linear drains:

Material Durability Maintenance Cost
Stainless Steel High Low Moderate
PVC Moderate Moderate Low
Polymer High Low High

Installing the Drain Frame

Once the shower area is prepared and the drain selected, the next step is to install the drain frame.

  • Position the drain frame in the designated area.
  • Use a level to ensure it is correctly aligned with the slope of the subfloor.
  • Secure the frame using appropriate fasteners, ensuring it is flush with the surface.

It is crucial to double-check the alignment at this stage, as any misalignment can lead to water pooling and drainage issues later.

Setting the Drain Body

With the drain frame in place, the next step involves setting the drain body.

  • Apply a layer of thin-set mortar around the drain frame.
  • Position the drain body into the mortar, ensuring it fits snugly and is level.
  • Allow the mortar to cure as per the manufacturer’s instructions.

It’s advisable to test the drainage by pouring water into the shower area to confirm that it flows towards the drain correctly.

Installing the Flooring and Grate

After the drain body is set and the mortar has cured, proceed with the installation of the flooring and grate.

  • Lay your chosen tile or flooring material, ensuring it fits around the drain.
  • Cut tiles as necessary for a clean finish at the edges of the drain.
  • Allow the flooring to set completely before proceeding.

Once the tiles are set, install the grate on top of the drain body. Make sure it sits securely and is flush with the surrounding tiles to prevent tripping hazards.

Finalizing the Installation

The last step involves final checks and ensuring everything is properly sealed.

  • Apply silicone caulk around the edges of the drain grate to prevent water from seeping underneath.
  • Clean any excess mortar or grout from the grate area.
  • Allow all materials to cure as recommended by the manufacturer.

By following these detailed steps, the installation of a linear drain in a shower can be accomplished successfully, leading to an efficient and stylish drainage solution.

Preparing the Shower Area

Before installing a linear drain, it is crucial to prepare the shower area adequately. This step ensures that the installation process runs smoothly and that the drain functions correctly.

  • Remove Existing Fixtures: Take out any existing shower fixtures, tiles, or flooring materials that may obstruct the installation of the linear drain.
  • Clean the Area: Thoroughly clean the subfloor and walls to remove debris, dust, or any residue that may affect the installation.
  • Check for Level: Use a level tool to ensure the subfloor is even. If necessary, use a self-leveling compound to create a flat surface.

Choosing the Right Linear Drain

Selecting the appropriate linear drain is essential for both aesthetic and functional purposes. Consider the following factors:

  • Size and Length: Linear drains come in various lengths. Choose one that fits the width of your shower space.
  • Material: Stainless steel is a popular choice due to its durability and resistance to rust. Plastic options are available but may not be as long-lasting.
  • Design: Opt for a design that complements your bathroom aesthetics, including finishes and grate patterns.

Installing the Linear Drain

Once you have prepared the area and chosen the right drain, proceed with the installation. Follow these steps:

  1. Create a Sloped Subfloor: The subfloor must slope towards the drain for proper water drainage. Aim for a slope of 1/4 inch per foot.
  2. Set the Drain Base: Position the linear drain in the desired location. Ensure it is flush with the subfloor.
  3. Secure the Drain: Attach the drain base to the subfloor using screws or adhesive, as per the manufacturer’s instructions.
  4. Connect the Drainage Pipe: Connect the drain to the existing plumbing. Use PVC cement for plastic pipes or appropriate fittings for metal pipes.
  5. Seal the Connections: Apply silicone caulk around the edges of the drain to prevent any leaks.

Tiling Around the Linear Drain

Tiling is a vital step that enhances the shower’s appearance while ensuring proper water flow towards the drain.

  • Choose Suitable Tiles: Select tiles that are slip-resistant and suitable for wet areas.
  • Apply Thin-set Mortar: Spread thin-set mortar over the subfloor, using a notched trowel for an even layer.
  • Lay the Tiles: Start from the farthest corner and work your way towards the drain. Ensure that the tiles are sloped towards the drain.
  • Cut Tiles as Necessary: Use a tile cutter to adjust tiles that fit around the linear drain.
  • Grout the Joints: Once the tiles are set, apply grout between the tiles, ensuring a waterproof seal.

Final Touches and Testing

After the tiles have been installed and the grout has cured, perform final adjustments and testing.

  • Install Drain Grate: Place the linear drain grate over the drain, ensuring it fits securely.
  • Test for Leaks: Run water in the shower to check for leaks and ensure that water flows toward the drain as intended.
  • Seal Edges: Apply a final bead of silicone caulk around the edges of the drain to secure it and provide additional waterproofing.

By following these steps, you can successfully install a linear drain in your shower, combining functionality with modern design.

Time and again, I saw people treat their bathrooms as stopovers places to rush in and out. But I saw potential for so much more. This site is built on that belief. It’s not just about better faucets or softer lighting.

It’s about building a space that supports rest, safety, and renewal whether you’re bathing your newborn, recovering from surgery, or just trying to reclaim a moment of peace.
