A standard range of epoxy resin sinks and troughs are moulded complete with a fixing flange in order to simplify fitment and to optimise the integrity of the joint with the worktop.
An overhang (underslung) sink is bonded and screwed to the underside of a worktop with the worktop slightly overhanging the sink opening. This type of fitment is also commonly referred to as 'underslung'. This fitment is adequate for many general laboratory applications.
The base of the sink slopes to a hole rebated to accept a waste fitting.
Sinks can also be drilled to accept an overflow fitting.
