There are no unbreakable rules of design, but experts recommend against using large tiles in areas with poor subflooring where they’re more prone to cracking, in areas where the floor isn’t entirely level, over raised areas or dips, and in bathrooms where budget is the primary concern. The size of your bathroom shouldn’t be a reason not to use large tiles; in fact, larger tiles, also known as slab tiles, can be a modern and sleek choice for bathroom floors and walls.

No, you don’t need to remove the old grout before installing new tile over existing tile. In fact, the old grout helps fill in gaps between tiles, creating a more even surface for the new layer. However, it's important to ensure that the grout is clean, solid, and free of cracks or crumbling areas. Damaged grout should be repaired or replaced before proceeding. Cleaning the surface thoroughly and filling any low spots will help the new adhesive bond properly and ensure a smooth, stable installation.

The best trowel for penny tile is a 3/16-inch-by-5/32-inch V-notch trowel. Because of the small size of the penny tile, you want a trowel with small notches that can lay a thin layer of mortar on the surface you’re tiling. If the notches are too wide, you risk applying too thick of a layer of mortar, and it can squeeze out between the penny tiles.

You can technically install tile over tile, but we don’t suggest it. Installing tile over any surface that isn’t a completely flat and prepared subfloor will result in a shoddy overall job, uneven flooring, tiles that don’t adhere, extra weight, gaps, cracks, and room for moisture and dirt to enter. For the best results, only install new tile on a flat, sanded surface like subflooring or concrete that is prepared for tile.

If you have asbestos tile and would rather tile over it than remove it, or if your existing tile is completely flat and bonded tightly to the floor, you may be able to tile over existing tile. But experts recommend thinking twice before you do.
