Use precaution when undertaking the installation and choice of tile. I say that because not all tile is what it seems to be, for example the home depot, Lowes tile can be varied in size up to 3/16th of an inch especially for inexpensive tiles and if they are not of the same “lot” number which means the grout lines can vary a bit in order to achieve a straight line appeal. Most of the more expensive tile from strictly tile stores you can expect to pay substantially more, but the end result is much better. One important note is to select surface appropriate tile, as an example do not use wall tile on the floor, as the wall tile is quite fragile and using it on the floor will result in cracking and braking. The use of different mix of tile and trim/décor tile can enhance the finish appeal of the areas you plan on tiling as well as the use of shelving and wall inserts for soaps and shampoos.
