I saw a couple on Signature Hardware.

Barnes Custom Builders thanks for the lead. I popped over there. They have a lot of cute ones, including some with backsplashes, but I didn't see any shelves. If I'm missing something, let me know. Thanks!

Or a porcelain shelf above the sink.

Would you be willing to do a tile backsplash? the ones with built in back and a shelf aren't that common.

this one from Kohler is really pretty

and no shelf, but you could add one afterward

ci_lantro yes I was thinking of doing a (glass?) shelf above the sink since there's no counter space (my pet peeve). Something like this.

Unfortunately I can't do a recessed medicine cabinet for the mirror. Maybe I could do a recessed cubbie on the side. (?) Something to consider. Thanks.

Beth H. : thanks for your ideas. They are wonderful as usual. I'd like to avoid tile, due to the expense. I had seen that Kohler but thought maybe something with softer lines, since the room is so angular at 3x8. But I LOVE that last one you posted. In fact, I have it in my cart right now at Lowe's.( I almost posted the pic, but Houzz doesn't seem happy when I post more than 2 pics were post.) How would I add a shelf later on???

I did find this one here but the OP didn't reveal the source. (actually, I'm not sure how this shelf is attached. Hmmm...."

Thanks for all your help!

You might be able to use a regular glass shelf or one w/brackets, mounted to the wall.

or see if the legs have the ability to accent aftermarket screws that hold the glass shelf.

if the shelf is more important, get one w/the shelf and forget the backsplash. a painted wall will be fine. and adding a small tile backsplash is easy and wouldn't cost more than $50, depending on tile you choose.

Beth H. : Interesting idea on the shelf. Do you mean just add a tile backsplash only behind the sink? Interesting...

fwiw, this is the bathroom I'd use most often coming in from gardening, so I don't want to be in a hurry, splashy direct water directly onto a wall. thanks!
