The single lavatory sinks appear to be LAV1 – HC (and the make & model would be fine, however as per the plumbing schedule LAV2 – HC & LAV3 – HC call for the same make & model. These would appear to be Bradley MG3 series – a three (3) sink molded assembly. However the drawings show only two (2) banks of three (3) sinks and four (4) banks of four (4) sinks. Please advise upon how to proceed?

on moisture-resistant core (which is what we’d use for a shop-made laminate
