Tiling around a bathtub is one of the most impactful updates you can make in a bathroom, combining waterproofing with a design statement that instantly elevates the space. Whether you are refreshing tired grout or executing a full remodel, doing the work yourself offers significant savings and a deep sense of accomplishment. This guide walks you through the entire process, from initial measurements to the final grout haze removal, ensuring a professional-looking finish that stands the test of time.
The key to a flawless tile installation lies in meticulous preparation, especially in a wet area like a tub surround. Unlike a wall in a dry room, this area is subject to constant moisture, temperature changes, and physical stress. Skipping essential steps like installing a proper backer board or using the correct thin-set mortar can lead to cracked tiles, mold growth behind the walls, and costly repairs down the line. Investing time in understanding these fundamentals is what separates a quick fix from a lasting renovation.
Planning Your Layout and Materials
Before purchasing a single tile, you need a clear plan. Start by measuring the total square footage of the area, adding an extra 10% for cuts and waste. Consider the tile size; larger formats can make a small bathroom feel more spacious but require more precise leveling. Decide on the pattern—straight stack, herringbone, or windmill—as this dictates how you cut the border pieces. Having a detailed sketch prevents mid-project guesswork and ensures you buy the right amount of material.
Essential Tools and Supplies
- Tile spacers and tile cutter
- Notched trowel for adhesive application
- Level and pencil for layout marking
- Grout float and rubber grout squeegee
- Tile saw for intricate cuts
- Safety goggles and gloves
Equally important is the selection of the right products. Choose a polymer-modified thin-set mortar specifically rated for wet areas and vertical applications. Your grout must be sanded for joints wider than 1/8 inch and non-sanded for smaller ones, and it should ideally be epoxy-based for maximum stain resistance around the tub. Don't forget the necessary trim pieces, such as bullnose edging for a clean, finished look where the tile meets the drywall.
Step-by-Step Installation Process
Begin by removing the old tile or ensuring the existing surface is clean, dry, and structurally sound. If you are tiling over drywall, you must first install cement board or a similar water-resistant backer board, sealing the seams with mesh tape and thin-set. Next, create your layout by finding the center point of the tub and snapping level vertical and horizontal lines. Dry-fitting the tiles without adhesive allows you to see how the pattern aligns and ensures you aren’t left with sliver cuts at the edges.
When you are ready to set the tiles, mix the thin-set to the consistency of peanut butter and apply it to the backer board using the notched trowel. Press each tile firmly into place, wiggling it slightly to ensure good contact with the adhesive. Immediately insert the tile spacers to maintain consistent grout lines, and double-check that each tile is sitting level with the tub surface. For the inside corners, use a corner cutter or nippers to create precise angles, and consider using a tile gauge to maintain even spacing across the entire field.
Grouting and Final Sealing
Once the adhesive has cured—usually after 24 hours—it’s time to grout. Mix the grout to a smooth, creamy consistency and force it into the joints using a rubber grout float, holding it at a 45-degree angle. Work in small sections to prevent the grout from drying on the tile surface. After about 15 to 20 minutes, use a clean, damp sponge to wipe away the excess, rinsing frequently to avoid scratching the glaze. Perform a final pass with a soft cloth once the haze begins to set.
The last critical step is sealing. Apply a high-quality grout sealer to protect the joints from the daily onslaught of steam and water splashes. This preventative maintenance task should be done annually to extend the life of your work. With the grout sealed and the bathroom aired out, you will have transformed the area around your tub into a stunning, waterproof feature that looks like it was done by a pro—because, with the right planning and execution, it was.
