Just saw it on the phone post. It is perfect.
Wow! Just found this while searching for something else!
My Message Center Niche is: 48"H x 20"W x 7" deep
Sorry I didn't answer this sooner!
Here is a link that might be useful: Link to Message Center Niche Pictures
If I had it to do over, I would make it taller - most of the Pantry wall from a few inches off the floor to the top of the current niche. I could have added a couple of shallow shelves below the "message center" shelf for decorative or other use.
Thanks buehl. Can't believe you found this old post.
