Topzero Countertops in Seattle

Topzero builds the integrated stainless steel sinks that disappear into stone countertops — no rim, no shadow line, no lip to catch crumbs. AbsoluteGM is a certified Topzero installer, one of a small number of fabricators in the Pacific Northwest authorized to do the precision install Topzero requires.

What makes a Topzero sink different

Topzero sinks are designed specifically to mount flush with stone countertops. The sink rim sits exactly level with the polished stone surface — a continuous plane from countertop to sink basin. Achieving that fit requires sub-millimeter precision in both the sink fabrication (USA-made, machined to spec) and the stone cutout (CNC-cut on our shop floor in Kirkland). Most Seattle-area fabricators install standard under-mount sinks; very few do the integrated flush-mount pattern Topzero specializes in.

When Topzero makes sense

High-end residential kitchens where the homeowner wants a continuous stone-to-sink visual line. Modern minimalist designs where every transition counts. Commercial kitchens that need the easy-clean profile of a flush sink. Stone choice does not matter — we install Topzero with quartz, quartzite, marble, granite, sintered stone, and porcelain.

Pricing and lead time

Topzero sinks themselves run \$1,800-\$4,500 depending on size and configuration. Add \$400-\$800 for the precision cutout and install (vs. a standard under-mount cutout which is typically \$150). Lead time from order is 4-8 weeks. AbsoluteGM coordinates the sink delivery with the countertop fabrication so install happens in one visit.

Frequently asked about Topzero

What is the difference between a Topzero sink and a standard under-mount?
Topzero sits flush with the stone surface (sink rim level with the countertop). Standard under-mounts sit slightly below the stone, with the stone overhanging the sink edge. Topzero gives a cleaner, more modern look but requires more precise fabrication.
How much does Topzero installation cost?
The sink itself is \$1,800-\$4,500. Installation adds \$400-\$800 to the standard sink-cutout cost. Total Topzero install in Seattle typically runs \$2,500-\$5,500.
Can Topzero be retrofitted into an existing kitchen?
Yes, but only with new countertops. The cutout precision required for Topzero cannot be reliably done on existing installed stone. Most Topzero installs happen during a full kitchen remodel or new countertop install.
What stone materials work with Topzero?
All major countertop stones: quartz, quartzite, marble, granite, sintered stone (Dekton, Neolith, Lapitec), porcelain. AbsoluteGM has installed Topzero with each.
How durable are Topzero sinks?
Topzero sinks are 16-gauge stainless steel, made in the USA. Lifetime structural warranty. The flush installation actually protects the sink edge better than a standard under-mount.
Is AbsoluteGM certified to install Topzero?
Yes. We are a certified Topzero installer. The certification matters because Topzero requires sub-millimeter cutout precision and specific sealing techniques that not all fabricators are trained on.
