Tile decals for your kitchen make your kitchen look absolutely beautiful and guess what?, they are really not that expensive. They are very durable and will last a long time,
They can make a plain wall stand out!
Tile decals are removable but can damage your walls because of the strong adhedsive on the back. I would not recommend applying them over wallpaper. If applied over wallpaper, they will most likely not be able to be removed due to pulling the wallpaper off as well.
They do look real and the cost is very reasonable. If you want to go with a waterproof tile decals then you should go with the vinyl. Vinyl is more durable and will last through moisture. As we all know, a kitchen gets a lot of use as far as cooking, washing dishes, etc., so you definitey want to add the vinyl tiles to withstand the moisture of cooking and washing dishes. Also, they can be wiped down without damaging them. There are so many different designs to choose from.
