How to Tile Corners in Shower

To tile shower corners, first clean and prep the area by removing old caulk and patching holes. Attach cement backer board and apply waterproofing membrane to prevent leaks. Choose moisture-resistant tiles and use precise cuts for inside corners; use bullnose or mitered edges for outside corners to ensure smooth joints. Press tiles firmly with spacers for even grout lines, then grout and seal to protect against water damage. Keep going to discover tips for perfect cuts and professional finishes.

Preparing the Shower Corners for Tiling

Before you start tiling, make sure the shower corners are clean, dry, and free of any old caulk or debris. Use a utility knife or scraper to carefully remove lingering caulk and any loose material.

Next, wipe down the area with rubbing alcohol to eliminate soap scum and oils that can prevent proper adhesion.

Inspect the corners for any damage like cracks or holes; patch these with a waterproof filler and let it dry completely.

Once smooth and solid, sand the patched spots lightly to create an even surface.

Finally, ensure the corners are fully dry before moving on.

Taking these steps will prepare your shower corners perfectly for tiling, helping the tiles to stick well and last longer.

Choosing the Right Tiles and Tools

With your shower corners prepped and ready, it’s time to pick the tiles and tools that will make your project both effective and visually appealing. Choose tiles specifically designed for wet areas—porcelain or ceramic tiles with a matte finish offer durability and slip resistance. Smaller tiles or mosaics work well in corners, allowing for easier fitting and fewer cuts.

Select waterproof grout and adhesive to ensure longevity. For tools, you’ll need a tile cutter or wet saw for precise cuts, a notched trowel to spread adhesive evenly, and tile spacers to maintain consistent gaps. A level and rubber mallet will help you set tiles flush and even.

Don’t forget safety gear like gloves and goggles. The right selection sets a solid foundation for a successful tiling job.

Applying Waterproofing and Backer Board

Since moisture is the biggest challenge in shower corners, you need to apply waterproofing and install a backer board to protect the walls and ensure durability.

Start by attaching cement backer board to the studs, cutting it to fit snugly in the corner. Secure it with corrosion-resistant screws, spacing them about 8 inches apart.

Once the backer board is in place, apply a waterproofing membrane or liquid waterproofing on all seams and corners. Use a brush or roller to spread the waterproofing evenly, ensuring full coverage.

Pay special attention to corners and joints, reinforcing them with waterproof tape if required. Let everything dry completely before moving on.

This step creates a moisture barrier that prevents water damage and mold growth, setting a solid foundation for tiling your shower corners.

Cutting and Fitting Tiles for Inside Corners

When you start cutting and fitting tiles for inside corners, accuracy is key to achieving clean, professional-looking results. First, measure the corner carefully, accounting for any irregularities in the wall or tile size. Use a tile cutter or wet saw to make precise cuts, ensuring tiles fit snugly without gaps.

Dry-fit the tiles before applying adhesive to confirm alignment. When placing the tiles, maintain consistent grout lines by using spacers. Press tiles firmly into place, checking that edges meet squarely in the corner. If needed, use a tile nipper to trim small sections for a perfect fit.

Finally, clean excess adhesive immediately to avoid grout issues later. Taking your time with cutting and fitting inside corner tiles sets the foundation for a seamless shower finish.

Techniques for Tiling Outside Corners

Although tiling outside corners can be challenging, using the right techniques will help you achieve sharp, clean edges. Start by selecting bullnose tiles or edge trim pieces designed specifically for outside corners; they provide a smooth, professional finish.

If you don’t have bullnose tiles, carefully miter-cut your tiles at a 45-degree angle to create a seamless corner joint. Measure twice and cut once to ensure accuracy.

When installing, apply thin-set mortar evenly and press tiles firmly into place, aligning edges precisely. Use spacers to maintain consistent grout lines around the corner.

Take your time to check alignment frequently, as slight misplacements are more noticeable on outside corners. With patience and precision, your outside corners will look crisp and durable.

Grouting and Sealing the Tiled Corners

After you’ve carefully installed your tiles, grouting and sealing the corners become essential steps to protect your work and enhance its appearance. Start by mixing grout to a smooth consistency, then use a rubber float to press it firmly into the joints, especially focusing on the corners where gaps can trap moisture.

Wipe off excess grout with a damp sponge before it dries, ensuring clean, crisp lines. Once the grout cures completely—usually after 24-48 hours—apply a high-quality grout sealer to the corners. This prevents water penetration and mold growth, extending the life of your tile job.

Don’t forget to reseal periodically, following the manufacturer’s recommendations. Proper grouting and sealing will keep your shower corners looking fresh and durable for years to come.

Frequently Asked Questions

How Long Does It Take for Tile Adhesive to Dry Before Grouting?

You should wait about 24 hours for tile adhesive to dry before grouting. This ensures a strong bond and prevents shifting. However, always check the adhesive instructions since drying times can vary based on product and conditions.

Can I Use Regular Grout in a Wet Shower Corner?

You shouldn’t use regular grout in wet shower corners because it can absorb water and crack. Instead, use waterproof grout or epoxy grout to ensure durability and prevent mold or water damage in those areas.

What Is the Best Way to Clean Tiles Without Damaging Grout?

You should use a gentle cleaner like a mixture of vinegar and water or a pH-neutral tile cleaner. Avoid harsh chemicals and scrubbing brushes, which can damage grout. Soft cloths or sponges work best for cleaning.

Are There Tile Patterns That Make Shower Corners Look Larger?

Yes, you can use diagonal or vertical tile patterns in shower corners to create an illusion of height and space. Lighter colors and larger tiles also help make corners appear bigger and more open.

How Often Should Shower Corner Grout Be Resealed?

You should reseal shower corner grout every 6 to 12 months to prevent moisture and mold buildup. Check for discoloration or water absorption, and if you spot any, it’s time to reseal and protect your grout.

Conclusion

Tiling shower corners might seem tricky, but with the right prep and tools, you’ll get a clean, professional look. Remember to waterproof properly and choose tiles that fit well in tight spaces. Take your time cutting and fitting both inside and outside corners for a seamless finish. Once tiled, grout and seal carefully to protect your work. Follow these steps, and you’ll enjoy a beautiful, durable shower corner that stands up to daily use.
