My parents recently bought a home with a guest bathroom displaying the most interesting layout I have ever seen. A linen closet, floor to ceiling, between the two sinks. Acting as a barrier between the two sinks.
The restroom seems to be very useful for sharing, maybe teenagers, or guests whom are not a couple. It also allows house guests to use the powder room's sink and mirrors for vanity reasons at the same time.
When my sister and I are both home- we LOVE the feature. We can both have our space to blow-dry, do our makeup, brush our teeth and get ready for bed- and be together in the space without feeling as if we were invading one another's space. The problem is the way it looks. Something feels awkward about the appearance of the closet, until I saw the restroom above I had no idea what we were going to do with the space. Here it is mom! This ones for you.
