During initial consultations and during projects I have noticed one huge trend. There is rarely spare tile to help the transition of the remodel into the house. I always say get extra tile if you are looking to redo anything. Tile tends to chip or break and if you are looking to replace those cabinets in the kitchen down the road, there is no tile underneath so having a few extra laying around can be a huge help future projects run smoothly. This can also be said for wood flooring. If you are entering a remodel and there is no extra around the house, a good eye and some hunting and you may get close.
Get extra tile and make sure you keep the name of all your materials somewhere. You will definitely use it in the future!
