The easiest tile size to install is large tiles, and they’re easier to install than small tiles—the job is faster and simpler when there’s less placing, adhering, and grouting to do. However, when tiles get really big, they’re more difficult to handle, cut, and fit. Standard floor tile sizes are 12-by-12 inches, 18-by-18 inches, and 12-by-24 inches.

Granite countertops cost an average of $3,250 compared to $2,250 for tile countertops. Granite is also harder to DIY than tile, given its weight and bulk, which increases the overall labor cost of installation. Over time, both types of countertops may need sealing to remain resistant to water, heat, and other common kitchen elements.

Tile countertops can be an excellent and budget-friendly option for a kitchen, provided they are installed correctly. It's important to choose tiles, such as ceramic, that are heat-, water-, and scratch-resistant. When the grout is properly sealed, it will resist stains, making the surface easy to clean. Tile is also considered a sustainable material. For a cohesive kitchen design and added protection, you can pair a tile countertop with a matching tile backsplash.

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.
