What it costs to replace a benchtop in NZ, why stone takes two visits and laminate takes one, and the joinery work people do not budget for.

Quick answer

A benchtop replacement is priced per square metre of material plus fabrication, and the material choice moves the total more than anything else. Laminate is a single visit. Engineered stone is two: a template once the old top is off, then installation about a week later. Budget for the sink, tap and any cooktop cut-out as separate line items, because they are.

Key points

  • Material choice is the whole story. Stone is several times laminate for the same run.
  • Stone needs templating after the old top comes off, then roughly a week in the factory. Laminate is usually one visit.
  • You will need a new sink and tap in most cases. Old ones rarely survive removal or suit the new cut-out.
  • Cabinets have to be level before a stone top lands, and that work is easy to leave out of a quote.
  • If the doors are also tired, do both together. A new top makes old doors look worse.

Benchtops fail long before cabinets do. They take the heat, the water, the knives and the weight, and after fifteen or twenty years a laminate top with swollen joints or a chipped stone edge is usually the thing that makes an otherwise sound kitchen feel finished. Replacing just the top is a genuinely good renovation when the cabinetry underneath is still solid.

How the price is built

Benchtops are quoted on the area of material, but the area is not the length of your bench. Fabricators work from sheet or slab sizes, and an L-shape or a run with an island uses more material than the finished square metres suggest because of the offcuts. That is why two kitchens with the same total bench area can price differently.

Why stone takes two visits

This surprises people and it is worth planning around. Engineered and natural stone cannot be measured off a drawing to the accuracy they need. The old benchtop comes off, the cabinets are levelled, and only then does a templater come and take the actual shape, usually with a laser or a physical template. That goes to the factory, the slab is cut and polished, and it comes back to be installed.

That gap is normally about a week. During it you have cabinets with no top, which means no sink and no cooktop if yours is a drop-in. It is manageable, but it is not what people expect when they hear the install takes a day.

The things people leave out of the budget

  • A new sink. Old sinks are usually silicone-bonded in and rarely come out intact, and an old drop-in will not suit a new undermount cut-out.
  • A new tap, or at least a new flexi set. Reusing a twenty-year-old tap on a new top is a leak waiting to happen under a benchtop you just paid for.
  • Splashback. Removing a benchtop almost always damages the bottom row of tiles or the base of a glass splashback.
  • Levelling the cabinets. Non-negotiable for stone, and it is real labour.
  • Making good the wall behind, because there is usually a raw strip once the old upstand comes away.

Laminate has moved on

It is worth saying plainly, because a lot of advice online is a decade out of date. Modern laminate is a printed stone-look decor under a wear layer, and in a rental, a townhouse or a family kitchen that takes daily punishment it is a completely sensible choice. It goes in in one visit, it costs a fraction of stone, and postformed profiles have no joins to fail at the front edge.

Where stone earns its money is heat, resale perception and a big island where the top is the visual centre of the room. Where it does not is a compact galley in a rental.

Doing it with the doors

If the doors are also past it, do them in the same visit. The access is already paid for, and there is a specific unpleasantness to spending money on a beautiful new stone top and then noticing every mark on the doors underneath it for the next two years.

Frequently asked questions

Can you replace a benchtop without replacing the cabinets?

Yes, and it is one of the better value renovations when the cabinetry is sound. The cabinets do need to be level and square enough to take the new top, which is part of the job on a stone replacement.

How long is the kitchen out of action?

A laminate replacement is usually a single visit. Stone means the old top comes off, a templater measures, and installation follows roughly a week later, so plan for that gap without a sink.

Do I need a new sink?

Almost always. Sinks are bonded in and rarely survive removal, and cut-outs are made to suit the specific sink, so the new top is machined around the new one.

Is engineered stone worth it over laminate?

It depends where the kitchen is doing its work. On an island that dominates a living space, yes. In a compact rental galley, modern laminate does the job for a fraction of the cost.

Will the splashback survive?

Assume it will not, entirely. Removing the old top usually damages the bottom course of tiles or the base of a glass panel, so budget for repair or replacement.
