The Foster sinks has an ingenious design that makes it simple to use a large set of optional accessories. On the topmost supporting step, the innovative Black grids slide, creating a large and practical surface to rinse food and crockery. The second step is meant to support and allow the sliding of a complete combination of accessories, which make some operations practical and safe: rinse, drain, slice, grate… everything can be done inside the sink. The third supporting step is on the bottom of the bowl. On this step one can rest the Black grids, making it possible to rinse foodstuffs without their coming in contact with the bottom of the sink, which may be dirty.
