Choosing a Kitchen Sink: Undermount, Integrated, and Granite Composite

Buying Guides · 2026-04-13 · 4 min read

The sink decision shapes your countertop fabrication. Mounting styles, materials, and how to pair Schock and Pyramis sinks with your surface.

Clients often choose their sink last, as an accessory. We encourage the opposite: choose it with the countertop, because the sink determines the cutout, the edge finishing, and part of the fabrication plan. Here is how we guide that decision at SLABTEK, where we carry both Schock granite composite and Pyramis stainless steel sinks.

Mounting Style Comes First

An undermount sink sits below the surface, giving you an uninterrupted sweep of countertop and no rim to catch grime — the default choice for quartz and porcelain worktops. The cutout edge becomes visible and must be polished to the same standard as the outer edges, which is precisely the kind of finishing our CNC machining center excels at. Top-mount (inset) sinks are simpler and more economical, resting on the surface with a slim rim; modern low-profile rims have made them respectable again in contemporary kitchens.

Granite Composite or Stainless Steel?

Schock invented the granite composite sink, and its appeal is obvious against a stone surface: matte mineral texture, deep colors that pair beautifully with dark Kedra or concrete-look Quartzforms, remarkable resistance to scratching and heat, and a quieter basin than steel. Stainless steel — our Pyramis range — remains the professional's choice: hygienic, effectively indestructible, and visually right in stainless-appliance kitchens.

Get the Cutout Right

Whatever you choose, the fabrication details decide the result: reinforcement around the cutout, correct overhang reveal on an undermount, structural adhesive bonding, and drainage grooves if you want them machined into the surface itself. Bring your sink choice to us before the slab is cut — or simpler still, choose both under one roof and let our team engineer the pairing.
