An undermount sink sits flush beneath the benchtop, so crumbs and water wipe straight into the bowl with nothing to catch on. QA Bathroom Warehouse stocks undermount kitchen sinks in Perth from Oliveri and Seima — most in dual under/overmount designs that install either way depending on your benchtop.

Why Undermount Works with Stone

Undermount installation is the natural partner for engineered stone and granite benchtops — the stone edge is polished and exposed, and the sink clamps underneath. There is no topmount lip to trap grime, and the look is seamless. Check your fabricator cuts the reveal you want: positive, negative or flush.

Dual-Mount Flexibility

Most of our Oliveri range is dual under/overmount — the same sink installs undermount in a stone benchtop or drops in as a topmount for laminate. That flexibility matters if you are staging a renovation: fit the sink now, upgrade the benchtop later, keep the same bowl.
