Though you can save money on—and add value to—bathroom remodels by tiling a shower, don’t put in a glass shower door. The reason is pretty simple—glass shower doors are extremely expensive, easy to break, and easy to get moldy. They need to be cleaned frequently and your tenants often won’t do this. Furthermore, they don’t do much to improve the aesthetics of your bathroom, at least not for the amount of money you spend on one.
