I have an older home. Screwed into the wall is an 8in by 8 inch stainless steel cup toothbrush holder. It is the kind that looks like a hidden door. You press in the door and the cup/toothbrush holder is on the other side and it swings around when you push the door. I was looking for something to mount there and take out his hideous thing. Any ideas what I can put there. I went to Lowes to see if they had an 8in x 8inc white soap dish but they did not. I would have to mount whatever I put there on the studs. Thanks
