Sub-surface installation means that the undermount sink is bonded in place directly under the SensiQ surfacing material. For this, the worktop is milled away below the worktop surface layer where the sink is then fitted and set in resin.
This creates a very subtle, delicate frame for the sink.
And it not only makes the cut-out absolutely watertight, it also provides the area around the sink with optimum protection from moisture. This mounting option makes the area around the sink easy and convenient to clean.
