This project has been in the planning stages for a long time. When I framed the bathroom mirror more than a year ago and had leftover trim, I thought it would be great for making a shelf. But it wasn't until last month when Luke (whom I love because he is awesome and also because he folds the laundry) said something like "Where am I supposed to put all these towels!", that I was motivated to move things along.
Like I said, I already had the trim pieces for the shelf support, I got that at Home Depot, but last time I checked they didn't carry in anymore. The shelf itself is a stair tread. I wanted the edge of the shelf to be rounded, but I don't have a router or any way to do that myself, so I was glad I found it. It was about three feet long but I cut it down with my miter saw. I wish it was deeper, though. The back doesn't quite reach all the way to the wall. So I just caulked the gap. Caulk is my best friend.
