I joined my parents and one of my sisters on the Washington coast at the end of August, where we stayed for a week in a rental house near the beach. The house was generally laid out logically and well appointed. Unfortunately, whoever handled shower faucet selection chose a design that, while sleek, obscures a core faucet function: how to switch the water flow from the faucet to the shower head.
No, not by pulling the handle in any direction. You turn the ring (which has no visual affordance) at the mouth of the faucet. Of course!
This design is acceptable in a private home (though not one I would choose), but a poor choice in a rental property, where the occupants are without a readily available source of information as to how the faucet operates. A phone call to the property manager revealed that many renters have experienced the same frustration with the design, which is apparently used in other houses in the development.
