Shower Soap Rack

My wife and I had many instances when we finish a bar of soap in the shower and as soon as we get out and dried off we forget to replace the bar with a new bar. So I decided to make a soap rack that holds four bars of soap, two of hers and two of mine, that is positioned on top of the shower in the corner. This way we will not have to use each others bar of soap when we forget to replace ours. I know, very silly, but we love it.
