Taking a hot shower is very soothing, but there is one thing that is annoying afterward, which tends to happen to the mirror. After a nice hot bath or shower, the mirror collects steam, making it hard to see. However, there is one country that loves to make the bathroom a luxury part of a home, and that is Japan.
Here is a solution to the steam problem by Japan. They add a heater behind the glass that allows the steam to run off instead of staying in place. With the heater in place, it makes the mirror viewable for your needs.
