Mastering the Basics: How to Tile a Shower Floor - Part 1
Embarking on a DIY tiling project for your shower floor can be a rewarding experience, transforming your bathroom into a personal oasis. This comprehensive guide, part one of a series, will walk you through the initial steps, from planning to preparing your shower floor for tiling. Let's dive in!
Understanding Your Shower Floor Tiling Project
Before you grab your tools and head to the hardware store, it's crucial to understand the scope of your project. Measure your shower floor area accurately to determine the number of tiles needed. Consider the tile size, as smaller tiles may require more cuts and time. Also, factor in any necessary trims or edging.
Choosing the Right Tiles and Adhesive
Selecting the right tiles is key to a successful shower floor installation. Porcelain or ceramic tiles are popular choices due to their durability and water resistance. Opt for tiles with a textured surface or slip-resistant coating to prevent accidents. Additionally, ensure your chosen adhesive is suitable for wet areas and the specific tile type.

Gathering Your Tools and Materials
- Tiles
- Tile adhesive
- Thinset mortar (if not using pre-mixed adhesive)
- Trowel (notched and straight-edged)
- Grout
- Grout float
- Sponge
- Tile cutter or wet saw
- Tape measure
- Level
- Chalk line
- Knee pads (optional, for comfort)
Preparing Your Shower Floor
Before laying a single tile, ensure your shower floor is clean, dry, and free of any debris. If your shower currently has old tiles or a membrane, remove them and any underlying adhesive using a chisel and hammer. Inspect the concrete subfloor for cracks or damage, repairing as necessary.
Waterproofing Your Shower Floor
Waterproofing is a critical step often overlooked by DIY enthusiasts. Apply a waterproof membrane, such as a liquid rubber or a peel-and-stick membrane, to your shower floor. This will prevent moisture from seeping into the subfloor and causing damage. Allow the membrane to cure according to the manufacturer's instructions before proceeding.
Laying Out Your Tiles
Before applying any adhesive, lay out your tiles on the shower floor to plan your design and ensure a symmetrical pattern. Start from the center of the shower and work your way outwards to avoid cutting tiles along the edges. Use spacers to maintain even grout lines. Once satisfied with your layout, remove the tiles and prepare to apply the adhesive.

Applying Tile Adhesive
Mix your thinset mortar or prepare your pre-mixed adhesive according to the manufacturer's instructions. Using a straight-edged trowel, spread the adhesive evenly across the shower floor, ensuring full coverage. Then, use a notched trowel to create grooves in the adhesive, allowing for better tile adhesion. Work in small sections to prevent the adhesive from drying out.
