TopZero Countertops in Seattle and the Eastside

TopZero is an engineered stainless steel sink system that sits nearly flush with the stone around it.

About the brand

What TopZero Is and What It Does Well

TopZero is an integrated sink system, not a slab brand. The basin is precision-made stainless steel designed to fit a CNC-cut opening in your countertop. The stone edge wraps over the basin lip, leaving only a hairline joint.

From above, the counter reads as one continuous surface, and the basin looks built into the slab. It works with a wide range of countertop materials, including quartz, quartzite, granite, marble, porcelain and sintered stone, as long as the slab is thick enough.

Strengths

  • Near-seamless look with a hairline joint
  • Stainless basin that resists impact and stains
  • Works with many countertop materials
  • The basin can be replaced without replacing the counter

Fabrication

How We Fabricate TopZero

  • TopZero Integrated Sinks Certified

    Stoneex Surfaces is listed as TopZero Integrated Sinks Certified. The installation spec is the reason the system works, so we follow it closely.

  • Cutout drawing before templating

    Each TopZero model comes with a cutout drawing. We need it before templating so the opening is planned to the basin's exact frame.

  • Digital templating

    Our team captures your cabinets, walls and layout digitally with the StoneEx System, so cuts and seams are planned before anyone touches a slab.

  • Fabrication specs and installation oversight

    We prepare the fabrication specs for the slab and oversee the installation, so the finished surface matches the layout you approved.

Questions

TopZero: Your Questions Answered

No. TopZero is a stainless steel sink system. It is installed into a countertop made from another material.

It suits quartz, quartzite, granite, marble, porcelain and sintered stone, if the slab is thick enough. Ask us to check your slab before you order.

A standard undermount leaves a visible gap at the rim. TopZero reduces that to a hairline joint and avoids the silicone bead where grime collects.

Yes. The basin can be replaced without replacing the countertop, which is not possible with a basin carved from the slab.
