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.

No, you don’t technically need a cement backer board for a wall tiling project, but not using it risks disastrous moisture damage. Cement is naturally water-resistant, whereas drywall soaks it in, which can lead to warping or mold growth. Always use a backer board treated with a waterproof membrane for bathrooms and other chronically damp areas to ensure complete tile shower waterproofing.

Yes, you can tile over existing shower tiles, but it's better to remove the old tiles first for the best results. Tiling over existing tiles requires a clean, level surface and proper adhesion. If the old tiles are in good condition, you can roughen the surface to improve adhesion. However, removing the old tiles ensures a smoother, longer-lasting finish and prevents potential issues down the line.
