Undermount Sink
An undermount sink is a premium kitchen inclusion that changes both the look and functionality of your kitchen bench. Mounted beneath the stone benchtop rather than dropped in from above, it creates a clean, seamless edge — but whether it's included or an upgrade varies between builders.

What is it?
An undermount sink is installed beneath the benchtop, so the stone edge is visible all the way around the sink opening. This creates a seamless, premium look and allows you to wipe crumbs directly into the sink. A top-mount (drop-in) sink, which most builders include as standard, has a visible rim that sits on top of the bench surface.
Why buyers compare it
- An undermount sink creates a cleaner, more premium kitchen look
- The seamless edge allows you to wipe directly from bench to sink
- Undermount sinks require stone benchtops (they can't be used with laminate)
- Some builders include undermount as standard with stone packages
Is it worth upgrading?
Questions to Ask Your Builder
Undermount Sink — Typical Costs

Premium undermount materials — designer look and durability
Compare My Build Tip
An undermount sink is only possible with a stone (or solid surface) benchtop — it can't be installed with laminate. If you're upgrading to stone anyway, ask whether the undermount sink can be bundled into the stone package rather than charged as a separate appliance upgrade.
