Topmount or Undermount: Which Laundry Sink Installation Suits My Benchtop?

A topmount laundry sink sits into a cut-out in the benchtop with its rim sitting on top. An undermount laundry sink sits below the benchtop, creating a cleaner, more continuous bench surface. The right choice depends on your benchtop material, the sink model, and the look you want. 

Not every sink can be fitted both ways, so check the exact product specification before making a decision.

We'd also get your cabinetmaker, stonemason, or installer involved before ordering. They need to confirm the cut-out, support, and compatibility with the benchtop you have chosen.
