If you choose not to have a door, however, you need at least a five foot distance to the doorway to avoid getting water out into the room. Even then, you need a lip to contain the water.

Showers and tub areas can be lined with plastic surround pieces, tile, or faux marble; or you can buy one piece showers or one piece tub with shower which are installed before the wallboard is installed.

You can see the cutout where the shower seat will be placed. I don't know why they cut that part out. It does show the insulation behind the greenboard.

We decided to have faux marble put up for walls and ceiling. We are really glad we chose this approach. We love the marble and highly recommend it even though it was a bit more expensive. They say you will get every dollar back when you sell the house.
This marble look is wonderful to clean. With a window squeegie you can wipe down the walls after each shower, and it's a whiz to keep the shower clean.

We had a seat installed in our shower, as well as a soap dish and two corner shelves. The shelves are just big enough for his and her shampoos, conditioners, and liquid soaps.

Some people even use this faux marble for their window sills too. We didn't use it for our sills throughout the house, but we bought some simple sills at the Home Depot.

For window sills, it is a good idea to have something that is easy to clean, rather than just using wallboard.
