Before it was builder grade with lots of 80's brass trim, even though our house was built in 2000 it looked very old and worn.
We worked with Home Depot and are very pleased with the results. It was finished reasonably quickly, though there was a week's delay when one of the pieces of glass got sent somewhere else.
It has to sit for 24 hours for the silicon to sit and the weather to warm up because when it's cold I want my hot bubble bath.
It is frameless and only has the trim at the top, the door is huge and opens in or out. Now I need to pick out a new shower head, I want one of the rain ones.
