Drop-in and drop-on sink and drainer units
Two simple ways to create a self-contained wet area of high chemical resistance in a worksurface of another material.
The SD15 and SD55 drop-in units are fitted into a rebated cut-out in the worksurface, so the surface sits level with or just below the worksurface and liquids run into the bowl. The drainer has a built-in fall.
The SD915 drop-on unit is surface mounted onto the worksurface and has a raised lip all round to contain spills.
All three are cast in one piece in the same epoxy resin as our worksurfaces, with the same chemical resistance, in all five standard colours.
