As there are many framed styles to choose from there are also options in terms of how the doors/enclosure will open. You can choose from sliding, fixed, hinged, pivoting and folding. As for the shape of the door, there are cornered, alcove, and round. You also need to take into consideration the different glass styles, from clear, frosted, patterned, obscure, and rain.
Before the enclosures are installed, make sure they are coated with surface protection or C10 before they leave the factory. C10 repels water, oils, and soap scums as well as blocks UV rays.
For cleaning shower doors, you can rinse the doors with clean hot water, let the hot water steam up the shower doors, and prepare them to be scrubbed loosening any bits of dirt or grime. You can also use commercial glass cleaner to spray down both sides, wipe out with a microfiber towel or paper towel. You can also do a DIY alternative with a spray bottle with vinegar or a bucket of water with vinegar and soak the sponge into solution and rub it to the doors. Some use a mixture of baking soda, water/vinegar. Just make sure to follow up wiping with dry paper towels or microfibers to avoid streaks.
Choosing the type of shower door is certainly as important as choosing the right tile for your new bathroom. If you choose the wrong door, it might ruin the overall look you are planning to achieve. As there are tons of options and market prices vary, you should carefully plan out the shower enclosure, as the overlook of the bathroom is affected by the choice of your shower door.
