Installing tile flooring in your shower is a common practice, but have you ever considered tiling the floor before the shower? This approach, known as tiling from the ground up, has its advantages and can enhance the overall look and functionality of your bathroom. Let's explore this method in detail, including its benefits, the process involved, and essential tips to ensure a successful outcome.
Why Tile the Floor Before the Shower?
Tiling the floor before installing the shower has several benefits:
- Easier Access: Tiling the floor first allows you to easily access the area around the shower drain, making it simpler to install the drain and ensure proper waterproofing.
- Better Alignment: Starting with the floor ensures that your tiles are perfectly level and aligned, creating a seamless transition between the shower and the rest of the bathroom.
- Enhanced Aesthetics: Tiling the floor first allows you to create a continuous, cohesive look throughout the bathroom, rather than having a distinct border around the shower.
Preparation: Planning and Materials
Before you begin, it's crucial to plan your tile layout and gather the necessary materials. Here's what you'll need:

- Tiles (floor and wall)
- Thinset mortar or mastic
- Grout
- Tile spacers
- Trowel
- Tape measure
- Level
- Cement backer board (if not using cement board shower pan)
- Shower drain
- Waterproofing membrane
Planning Your Tile Layout
Start by planning your tile layout, taking into account the size and shape of your bathroom and shower. Consider using larger tiles for a more spacious feel, and arrange them in a pattern that complements the rest of the bathroom. Don't forget to account for the shower drain and any other fixtures.
Installing the Tile Floor
Once you've planned your layout and gathered your materials, it's time to start tiling. Here's a step-by-step guide:
1. Prepare the Substrate
Ensure the subfloor is clean, dry, and structurally sound. If necessary, apply a cement backer board over the subfloor to provide a stable, waterproof surface for tiling.

2. Install the Shower Drain
Before laying any tiles, install the shower drain according to the manufacturer's instructions. This will allow you to ensure proper waterproofing and make it easier to install the tiles around the drain.
3. Apply the Waterproofing Membrane
Apply a waterproofing membrane to the entire area where you'll be tiling, including the shower and the surrounding floor. This will help prevent water damage and protect the subfloor.
4. Spread the Thinset Mortar
Using a notched trowel, spread thinset mortar onto the floor, following the manufacturer's instructions for the appropriate coverage rate. Ensure the mortar is evenly distributed and that there are no voids or air pockets.

5. Lay the Tiles
Starting from the center of the room or shower, lay the tiles according to your planned layout. Use tile spacers to ensure consistent grout lines and allow the mortar to set according to the manufacturer's instructions.
Tiling the Shower Walls
After the floor tiles have set and been grouted, you can begin tiling the shower walls. Start at the bottom and work your way up, using the same techniques as you did for the floor. Be sure to install any necessary shower accessories, such as niches or grab bars, as you go.
Finishing Touches
Once the wall tiles have been installed and grouted, you can apply a sealant to protect the grout and prevent water damage. Finally, clean the tiles and allow them to cure according to the manufacturer's instructions.
Tips for a Successful Tile Floor Before Shower Installation
- Allow Enough Time: Tiling from the ground up can take longer than installing the shower first, so be sure to allocate enough time for the project.
- Consider Hiring a Professional: If you're not comfortable tackling this project on your own, consider hiring a professional tile installer to ensure a successful outcome.
- Choose the Right Tiles: Opt for tiles that are designed for use in wet areas and have a slip-resistant surface to prevent falls.
Tiling the floor before the shower can be a rewarding project that enhances the look and functionality of your bathroom. By following these steps and taking the time to plan your layout, you can achieve a beautiful, cohesive result that you'll enjoy for years to come.
