Over a year ago I purchased these two wire window boxes for around a $100 (for both) on eBay.
There were a dozen places I could have used these in my house, but I decide tthey would be wonderful towel holders in my bathrooms.
This is an arched window in our walk-in shower. I placed the window box just under the window and keep it filled with rolled towels. All you have to do is reach around the corner after a nice long hot shower and your towel is right there.
Here's a view from inside the shower looking out at the main window and the bathtub.
This is the one in the guest cottage bath. A very small bathroom with limited space, this works out great as a storage solution. Just reach up and get a towel after your shower.
Now for my "look for less" tip. These ribbed towels are from K-Mart and the Jaclyn Smith Home Collection. They are wonderfully luxurious and very budget-friendly. They come in a variety of colors including a nice white-white.
