Sinks
Integrated, TopZero or undermount: which sink fits?
Three ways to get a sink with no raised rim: a basin carved from porcelain, a quartz top with a TopZero system, and the TopZero stainless system itself.
The options
Three Ways to Get a Sink With No Raised Rim
Porcelain Integrated Sink
A true stone-into-stone look with no metal joint, on a thick porcelain or sintered stone slab.
Read about Porcelain Integrated Sink
Quartz Integrated Sink
A quartz kitchen that wants a near-seamless sink, since quartz cannot be carved.

TopZero Sink Installation
A near-seamless sink in almost any thick countertop material, with a stainless basin you can replace.

How the Sink Options Compare, Criterion by Criterion
Which one fits your project
Pick what matters most to you. We rank the options using the table below. Nothing is sent anywhere.
Choose at least one priority to see a match.
| Criterion | Porcelain Integrated Sink | Quartz Integrated Sink | TopZero Sink Installation |
|---|---|---|---|
| Cleaning | Excellent No rim, lip or grout line, so you wipe straight from counter to basin. | Good A TopZero system keeps the joint tight. A seamless undermount leaves a rim that is harder to keep clean. | Good A hairline joint and no silicone bead for grime to collect in. |
| Scratch and stain resistance | Excellent A non-porous basin that does not stain or absorb water. | Good Quartz resists stains, and a stainless basin handles daily knocks. | Excellent Stainless steel does not stain and handles dropped pans well. |
| Heat | Excellent Tolerates boiling water and hot cookware without thermal shock concerns. | Needs care The resin in quartz can be damaged by high heat, so keep very hot pots off the edge. | Good The stainless basin handles heat. The stone around it sets the limit. |
| Seamless look | Excellent The basin is part of the slab, with no joint between counter and sink. | Varies Near-seamless with TopZero, and a visible gap at some angles with a seamless undermount. | Good A hairline joint where the stone wraps over the basin lip. |
| Repair and replacement | Needs care The basin is carved from the slab, so serious damage can mean a new slab. | Good The basin can be replaced without replacing the countertop. | Excellent The basin can be replaced on its own, without touching the countertop. |
| Installation style | Varies Carved from a thick slab with precise CNC work, so it needs a slab that can carry the basin. | Varies A stainless basin fitted to a cutout in a thick quartz slab, either TopZero or undermount. | Varies A stainless basin bonded into a CNC cutout, with a cutout drawing needed before templating. |
