A wash basin, as for a domestic bathroom, has normal inlet water faucet(s) and spigot(s) fitted at or above its top and a normal outlet or drain pipe at its bottom. The basin also has a peripheral inlet flow channel formed below its top rim, for creating a smoothly-flowing film of water cascading down the interior sides of the basin to the outlet. This flowing water film intercepts detritus such as shaving cream, toothpaste, and soap, preventing it from sticking to and soiling the interior of the basin. The basin preferably also has a peripheral overflow channel formed in its side wall adjacent but spaced from the peripheral inlet channel and communicating to the drain below any drain plug or stopper that may be used. The inlet flow channel preferably has a separate water supply and control so that it may be used either separately from or in addition to the regular water supply and so that it may alternatively be left off even while the regular water faucet(s) and spigot(s) are in use. The supply to the inlet film channel can be of hot, cold, or tempered water or may be adjustable by a user as to flow volume and / or temperature, as may be desired and permitted by the plumbing setup. The overflow channel and downstream passages to the drain are sized to pass the maximum volume of flows from the spigot(s) and the inlet channel combined, to avoid overflow of and spilling of water and other contents from the basin under most circumstances. The basin thus provided is clean and dramatic in both its interior and its exterior aspects, multiplying its use possibilities atop as well as inset into domestic cabinetry.
