A cup in a bathroom is an essential thing to have, and yet there never seems to be room to set one down. If you have limited space in your bathroom, installing a cup holder or two can solve the problem. Glass holders prevent water from pooling where the glass sits, they keep germs at bay and can be secured in easy to reach areas along any wall. Have trouble getting your kids to brush their teeth each night? Paint a kitty or doggy face on a wall cup and then name it. Then tell the kids, 'It's time to go see Scooby now,' and watch them scurry off to the bathroom sink.
