The Washstand is Insecure About his Size
That only leaves about maybe 1.5 inches of counterspace to be divided between the front and the back of the sink. Is that enough? I don't want the sink looking crowded or forced into the space, and we need room to actually turn the handles.
One thing I considered was the wall-mounted faucets intended for vessel sinks. See examples here. If you had a long enough faucet (like this one), would it be possible to use a wall-mounted faucet with an undermount or drop-in sink?
Also, is a 17.5 x 13-inch sink (like this one) or 16.75 x 13-inch sink (like this one) big enough? It will be used for tooth-brushing, shaving, and hand-washing.
