Bathroom sink

Since the advent of indoor plumbing for dwelling structures such as homes and hotels, efforts have been made to create plumbing fixtures such as sinks for bathrooms, lavatories and other environments which are practical yet esthetically pleasing, not only in their appearance but also in their operation. A bathroom sink is a necessity used for performing daily hygienic rituals, such as washing, toothbrushing or shaving. The desire of owners of homes, recreational vehicles, boats, aircraft, and the like, to decorate their home/vehicle with unique and elegant fixtures leads manufacturers and interior decorators to use more unique and expensive materials in the creation of such fixtures. This is especially true in the area of bathroom and kitchen fixtures. One such material used in the creation of bathroom and kitchen sinks is marble and various types of stone, such as granite. Bathroom sink constructions including a rigid bowl of stainless steel, porcelain and various other materials are well known and are normally installed in a counter top constructed of solid surface sheet material in order to support the sink from the solid surface sheet material and also to seal the periphery of the bowl or bottom of the sink to the solid sheet material. Conventional bathroom sinks include a peripherally extending upper rim which, when installed, rests upon the top surface of the adjacent portion of the countertop. The sink is secured in place by a clamp construction which engages the underlying surface of the countertop to prevent the sink from being raised or moved sideways. Various types of mounting or clamping devices are known for securing sinks to countertops. One style of sink commonly found in bathrooms in traditional homes, including especially renovated homes, is a pedestal sink. A pedestal sink appears as a sink bowl attached to a wall and supported by a narrow pedestal or column, with no cabinetry underneath the sink. Further, because of the configuration of the sink bowl of a pedestal sink, there is no counter space surrounding the sink. In modern construction bathroom sinks are normally recessed in an aperture provided therefor in a drainboard or other countertop arrangement. Sinks of the type manufactured from porcelain coated steel are normally supported and secured in the aperture by using a rim, conventionally manufactured for that purpose, which serves as both a seal structure between the upper, countertop level, flange on a sink and the drainboard and which also serves as a trim member to cover the gap normally left between the edges of the aperture and the periphery of the bathroom sink flange.
