I am getting a wall-mount sink for my tiny powder room, and I found a reasonably priced Whitehaus sink, but the bowl is only 11"x7.5" with a depth of 3.5". The powder room will be used primarily by guests, including my nine year old son's friends. My concern is whether there's enough room in the bowl to wash hands without making a splashy mess (the floor is wood). My other sinks are all generous undermounts, and I've never had a mini sink before. Does this size sound sufficient, or should I keep looking? The sink I'm looking at is below, but I would get the single faucet option so that I'd have room for hand soap on the other side. Thanks for your feedback!
