Shower screens, also known as shower doors, are made from plastic or fiber glass and are attached to ceramic walls using shower screen hinges. They are specifically designed to hold the weight of a solid door while gripping a ceramic wall with screws or high-grade epoxy. Quality is important because it must hold the weight of the door as well as the pressure of a human body.
Hinges for this purpose should have the exact thickness of the solid screen and also have a hinge joint that is able to bear a considerable amount of pressure. Only two hinges should be necessary, but more can be used if they are properly aligned. Only buy solid steel joints that are able to firmly grip the screen and the wall. A weak connection or a weak joint risks the lifespan of the shower door and supporting ceramic.
