Measure the width of the opening of the shower. Most doors have glass shower as an adjustment to the opening size shower. However, the typical frameless glass shower doors is at least 30 inches wide (76.2 cm), so if the opening is larger, a fixed panel on one or both sides would be a good design choice. Measure the height. The most common height for a shower door is 72 inches (182.88 cm). Make the door of the shower at least high as the shower head or as high as the tile if the tile does not go through the roof.
Choose a setting. The configuration of the glass panels depend largely on the size of the frameless glass shower doors. Smaller showers may need only a hinged door or bypass style (two doors that slide over each other). This style is very practical because it usually includes a built-in door towel.
When the doors are in the same plane it is called an aligned configuration. If the frameless glass shower doors abut the end of the tub or in a corner, you may want to have a transparent panel above the bath and the shower door open on the adjacent side.
