A method for manufacturing an approximately parallelepiped-shaped sink comprising a series of flat rectangular slabs made of ceramic/clay material, firmly connected to one another at their relative sides. the sides of the slabs are provided with connection bevels tilted in respect to the lying planes of the respective slabs with angles sized so that the support of the flat face of a connection bevel present on a side of a slab against the flat face of the connection bevel present on a connection side of another slab, determines a mutual perpendicular positioning between the two slabs; and firmly fixing the flat faces of the connection bevel by means of an adhesive composition.

A handwash station being frontally accessible from a user position, in which the hand-wash station has a base body including a front side, left side and right side, which base body supports a pivotally connected sink unit including a sink and a faucet for dispensing water. The handwash station is convertible from a left to a right version. In the left version, the sink unit is pivotable to the left side about a left pivot, and in the right version, the sink unit is pivotable to the right side about a right pivot. Due to the convertibility, the same handwash station is suitable to be placed either against a left or a right side wall of a portable restroom.

A fluid treatment and disposal system includes a sink, having a basin, a sink drain inlet, and a sink drain trap. An open cavity is disposed behind a rearward wall of the sink basin, between a top portion of the sink and the sink drain trap. A curved transition surface receives fluid entering the sink. Embodiments of the drain are shaped to promote the evacuation of fluid from the basin while limiting turbulence. An exhaust port fluidly coupled with the open cavity evacuates the open cavity and surrounding environment. Embodiments optionally associate one or more of the following with the open cavity: Ultra-Violet (UV) Germicidal Lights, and Ozone water, copper-silver ionization, and/or sanitizing agent injection systems.

According to one embodiment, a wet-area device includes a main part, a first layer, and a second layer. The first layer is provided on an outer surface of the main part. The second layer is provided on an outer surface of the first layer. A hardness of the second layer is greater than a hardness of the first layer. The first layer includes a first unevenness at a side of the outer surface of the first layer. The first unevenness includes a plurality of recesses and a plurality of protrusions. The second layer includes a second unevenness at a side of an outer surface of the second layer. The second unevenness includes a plurality of recesses and a plurality of protrusions. The second unevenness is arranged along the first unevenness. An average height of the first unevenness is less than an average length of the first unevenness.
