Once again Eric Rexrode, our Waterworks Outside Sales Consultant in Philadelphia, has kindly written this post. Thanks, Eric: We often get requests for fittings that can be mounted on the wall above the sink. I love this idea because it’s a great solution to gain more counter space as well as to use that often forgotten vertical layer in the bathroom. The wall above the sink is most commonly used for medicine cabinets, mirrors, lighting or a small shelf. But moving your faucet to this space can create an additional design element. This is the perfect solution when there is insufficient depth to properly mount a fitting in the counter. (A counter with a stone top and undermount oval sink should be no less than 23″.)
