How to Tile a Bathtub Surround with Subway Tiles: A Comprehensive Guide

Creating a stylish and functional bathroom involves a number of steps, including tiling around the bathtub. Subway tiles, known for their classic and aesthetically pleasing design, can offer a timeless finish to your bathroom. This guide will walk you through the process of tiling a bathtub surround with subway tiles, from preparing the surface to sealing the final touches.

Preparation Steps

Before you begin tiling, it is essential to ensure your surfaces are prepared correctly:

Make sure the outer walls are insulated and have a continuous vapor barrier to prevent moisture from seeping through. Install a tile backer board about five feet above the bathtub, ensuring it is fitted correctly around faucets and valves. Frame backers for your accessories, such as soap dishes, towel racks, and grab bars, as you may need them later.

Once the backer board is installed, cover it with a sealing product that adheres to the board, creating a waterproof layer. This is crucial to prevent moisture from damaging the walls and tiles.

Tiling Layout and Placement

Planning your layout is key to ensuring a professional-looking finish:

Measure for the quantity of tiles needed, dividing the rear wall into sections based on the length of your tiles, including grout space. Draw plumb lines and layout vertical lines to mark your tiling pattern. Plan for rounded tiles at the top and corners, ensuring seamless transitions.

Before you start tiling, know the exact placement of every tile. It is a good idea to visualize the final result or create a paper layout to avoid mistakes.

Tiling Process

The tiling process involves the following steps:

1. Mixing Thin Set Mortar

Select the appropriate size and notch type of trowels to mix the thin set mortar or mastic. Apply the mortar to the backer board, spreading and troweling a square foot or so at a time. Cover any areas you will not immediately tile with plastic to protect them from dust and moisture.

2. Setting Tiles

Begin setting the tiles by starting at the back of the wall. Ensure all tiles are level and true to the layout. Don’t forget to include your accessories, like towel bars and grab bars, by leaving the appropriate openings or installing them as needed.

3. Cutting Tiles

To create the radius in corners, you can use a scoring and snapping method, a rod saw, glass or masonry drill, or a diamond saw, which you can rent.

4. Grouting and Sealing

After setting all the tiles, grout the joints with a rubber float, floating the grout in at an angle. Sponge off any excess grout, apply caulk to corners, and tool the caulk as required. Once the grout has set, buff and remove any remaining film using oxalic acid. Finally, seal the tiles to protect them from moisture damage.

By following these steps, you can achieve a professional finish for your bathtub surround with subway tiles. However, if the process seems overwhelming, consider hiring a professional for the job.

Conclusion

Tiling a bathtub surround with subway tiles is a rewarding DIY project, but proper preparation and attention to detail are crucial. With a little effort and patience, you can achieve a stunning finish that adds value to your bathroom.
