Shower doors create a watertight seal that prevents liquid and moisture from leaking into the bathroom. These doors come in a variety of materials like glass and plastic, and they are less likely to harbor bacteria and soap scum than traditional curtains or vinyl. Some shower doors are mass-produced and can be purchased from stores, but others require custom sizing and fitting. If you would like a new door in your bathroom, then you might need to call a professional who can cut one correctly and install it with a watertight seal.
