1. A sink comprising
a basin portion having a level basin surface for receiving water;
a trench portion having a trench surface and a drain; and
a door having a surface configured to visually obscure the trench portion,
wherein,
the basin surface and the trench surface comprise a length and a width, the basin surface length being substantially the same as the trench surface length, and the basin surface width being greater than the trench surface width,
the trench surface is configured to receive water from the basin surface,
the drain is positioned along the trench surface length and comprises one or more holes configured for water to flow through to a connecting pipe,
the basin level surface and the trench surface are joined by an angled surface,
when the door is in a closed position, the trench portion is visually obscured and a gap is formed between an edge of the door and the basin surface thereby allowing water to flow from the basin surface to the trench surface,
the door is configured to be placed in an open position to allow access to the trench portion,
the door includes a door adjustment mechanism comprising a resilient member and a detent,
the door adjustment mechanism is configured to resist a user's force when the user pushes the door surface a first time to place it in the open position, to hold the door in the open position, and to return the door to the closed position when the user pushes the door surface a second time,
the trench surface is set at a lower position than the basin level surface, and
the lower position of the trench surface relative to the basin level surface is such that gravity causes water to flow from the basin surface to the trench surface.
