Engineered stone benchtops: cost & pros and cons

Engineered stone benchtops — quartz composites like Caesarstone — are made from crushed stone bound with resin. They give you the look of natural stone with a harder, non-porous, low-maintenance surface. In NZ you’ll pay roughly $500–$1,000+ per square metre installed. They resist scratches and stains brilliantly but aren’t heat-proof, and fabrication must follow strict silica-dust rules.

The pros

Hard-wearing and scratch resistant for day-to-day use. Non-porous, so it never needs sealing and strongly resists stains and bacteria. Consistent colour and pattern across the whole benchtop. A huge range of colours and finishes, including matte and textured. And it holds its value, adding real appeal when you sell.

The cons

It isn’t heat-proof — a hot pot straight from the stove can scorch the resin or thermally shock the slab, so always use a trivet. It’s heavier and pricier than laminate, and the realistic veining of natural marble is still subtly different up close. Dark, high-gloss colours can show fingerprints and fine scratches more than textured finishes.

What it costs in NZ

Supplied and installed, budget roughly $500–$1,000+ per square metre. Entry-level plain colours sit at the lower end; thicker slabs (40mm), premium veined designs, mitred waterfall ends and fancy edge profiles push it up. A standard L-shaped kitchen bench with an island will usually land somewhere in the middle of that range. We give you an exact figure in your written quote.

Caring for engineered stone

Clean with warm soapy water or a pH-neutral spray and a soft cloth. Avoid abrasive pads and harsh or highly alkaline cleaners, which can dull the surface over time. Wipe spills promptly, never cut directly on the stone, and always use a trivet under hot pots and appliances. Done simply, it will look excellent for decades.

Silica & safety — the NZ situation

You may have heard engineered stone was banned in Australia. That ban addresses silicosis — a serious lung disease caused by breathing in the fine silica dust released when the stone is cut and ground. New Zealand has not banned the product; instead WorkSafe NZ brought in tighter controls (from December 2024) for fabricators, requiring wet-cutting, dust extraction and proper respiratory protection.

For you as a homeowner this is reassuring: a finished, installed benchtop poses no silica risk at all — the hazard exists only during fabrication. We work with fabricators who follow the current WorkSafe requirements, so the people making your benchtop are protected too.
