You can, in theory, tile your fireplace hearth with most tiles. However just because you can, doesn’t mean you should. For example, it’s much better to use unglazed tiles because glazed tiles are more resistant to cracking under extreme heat. Porcelain is more heat-resistant than ceramic, but you can still design the hearth as you like by putting the most heat-resistant tiles directly under the fire and, if it matches your style, add more decorative tiles further from the center of the fire. 

You can attach tiles to a wall using thin-set mortar. You’ll also need a notched trowel to create grooves within the adhesive so it flattens completely when pressed in and securely holds the wall tiles. Finally, you’ll need grout to smooth the gaps between the tiles and, ideally, a grout sealer to prevent mold. While it sounds simple enough, proper planning and execution are crucial, so carefully review the steps in this guide or hire a pro tile installer to complete this project.

Yes, it’s always a good idea to keep a box or two of spare tiles after a home renovation project. Tiles can crack from improper installation, heavy foot traffic, and impact from drops. Having some extra tile on hand can make replacement fast, easy, and affordable. Plus, some manufacturers might discontinue particular colors or styles, and slight variations in tile colors between batches could mean mismatched tiles even if your product isn’t discontinued. Having a few spare tiles in storage can help avoid these issues, as well.

The choice of whether to tile or use an acrylic tub surround is up to you and can be based on a number of factors, including aesthetics, cost, waterproofing, ease of cleaning, and maintenance.

Tile is a beautiful, classic bathtub surround choice; while tile installation cost is higher, it’s customizable and offers visual appeal. Tile is also harder to clean and presents waterproofing problems because of grout lines. Acrylic surrounds can be more affordable, don’t require much maintenance, and are easier to clean. However, they aren’t usually as visually appealing and may need to be replaced if they become damaged.
