Tiling a Shower: Waterproofing, Drainage, and Design Considerations with Porcelain Tile


Tiling a shower is a meticulous task that requires careful planning and execution to create a beautiful and functional space. Whether you’re renovating an existing shower or starting from scratch, choosing the right materials and techniques is paramount. Porcelain tile is a popular choice for shower walls and floors due to its durability, water resistance, and versatility in design. In this comprehensive guide, we will explore essential tips for tiling a shower with porcelain tile, covering crucial aspects like waterproofing, drainage, and design considerations.

1. Start with a Solid Foundation

Before laying any porcelain tile in your shower, ensure that you have a solid and level foundation. Address any structural issues or water damage, as these can compromise the integrity of your tiling work in the long run. Properly prepare the shower substrate, ensuring it is clean, dry, and free from any debris.

2. Choose the Right Porcelain Tile

Selecting the right type of porcelain tile for your shower is crucial to ensure both aesthetics and functionality. Opt for porcelain tiles with a slip-resistant surface, especially for the shower floor, to prevent accidents. Consider tiles with a textured or matte finish to provide better traction underfoot.

3. Focus on Waterproofing

Waterproofing is the most critical aspect of tiling a shower. Properly waterproofing the shower walls and floor is essential to prevent water from seeping into the structural elements of your home and causing damage over time. Use a waterproofing membrane or a cement-based backer board with built-in waterproofing properties to create a watertight barrier.

4. Pay Attention to Drainage

Proper drainage is essential for preventing water buildup and ensuring a dry and clean shower area. Invest in a high-quality shower drain system that efficiently directs water towards the drain. Consider using larger tiles on the shower floor to minimize the number of grout lines, which can be potential water entry points if not properly sealed.

5. Plan the Tile Layout

Careful planning of the tile layout is necessary to achieve a polished and professional look. Determine the centerline of the shower walls and floors and use this as a starting point for laying the tiles. Consider using full tiles along prominent edges and corners, and plan tile cut to be inconspicuous or placed in less visible areas.

6. Use Thin-set Adhesive and Grout

For tiling a shower with porcelain tiles, it’s essential to use the right type of thin-set adhesive and grout. Choose a thin-set adhesive specifically designed for porcelain tiles to ensure proper bonding and durability. Similarly, opt for an epoxy or cement-based grout that is resistant to water and mould growth.

7. Seal the Grout

Sealing the grout is a crucial step to protect it from water infiltration and staining. After the grout has cured, apply a high-quality grout sealer to all grout lines. Regularly inspect and reseal the grout as needed to maintain its water-resistant properties.

8. Consider Tile Size and Pattern

Larger tiles can make a small shower appear more spacious, as they have fewer grout lines and create a seamless look. Consider using large-format porcelain tiles for the shower walls to achieve a modern and sophisticated appearance. Additionally, explore different tile patterns, such as herringbone or subway, to add visual interest to your shower design.

9. Incorporate Niche or Shelf

Incorporating a niche or shelf in your shower design provides convenient storage for shower essentials and adds a touch of elegance. Plan the location and size of the niche carefully during the tiling process to ensure seamless integration with the surrounding tiles.

10. Hire a Professional

If you lack experience in tiling or dealing with complex shower configurations, consider hiring a professional tile installer. A skilled tile installer will ensure that the shower tiling project is completed to the highest standards, with proper waterproofing and a flawless finish.


Tiling a shower with porcelain tile requires attention to detail and adherence to essential principles such as waterproofing, drainage, and design considerations. By starting with a solid foundation, selecting the right porcelain tile, focusing on waterproofing and drainage, and planning the tile layout carefully, you can achieve a stunning and functional shower space. Remember to use the appropriate thin-set adhesive and grout, seal the grout, and consider the tile size and pattern to enhance the overall aesthetics of your shower. With the right techniques and materials, you can transform your shower into a luxurious and inviting oasis that stands the test of time. If you’re unsure about the tiling process, don’t hesitate to seek assistance from a professional tile installer to ensure a successful and beautiful result.
