How a Stonemason Measures and Templates a Kitchen Worktop

A natural stone worktop is cut to fit one kitchen and no other. Walls are rarely perfectly straight, corners are seldom exactly square, and appliances and sinks need precise openings. That is why stone worktops are almost always made from a template taken on site, not from the measurements on a kitchen plan. Knowing how this step works helps you avoid delays and makes sure the finished top fits as it should.

When templating happens

Templating takes place after the kitchen units are installed and fixed in their final position, and before the stone is cut. The units must be level, firmly fixed and not moved afterwards, because the worktop will be made to sit exactly on them.

By this stage, several decisions need to be made:

  • The exact model of sink, hob and taps, ideally with the products or their cut-out drawings on site.
  • Whether the sink will be undermounted, set flush or sit on top of the stone.
  • The position of the tap holes and any extra holes, for example for a soap dispenser.
  • The overhang at the front and on any breakfast bar or island.
  • Edge profile, upstands and any stone splashbacks or window sills to be made at the same time.

Changing these after templating usually means a new template and a new cut, so it pays to settle them in advance.

How the template is made

There are two main methods, and many workshops use both depending on the job.

Physical templates: the stonemason cuts strips of thin board, plywood or plastic and fixes them together on top of the units, following every wall, corner and opening. The result is a full-size pattern of the worktop. It is marked with notes about edges, overhangs, sink and hob positions, and joint locations.

Digital templating: laser or photo-based measuring systems record the outline of the units and walls directly into a computer. The data goes to the workshop, where it can be used to program cutting machines. Digital templating is fast and accurate, but the person doing it still needs to understand how stone will be cut and fitted.

In both cases, the stonemason checks that the units are level, notes where walls are out of line, and decides where any joints between slabs will go.

Joints, veining and slab layout

Stone slabs have a maximum size, so long runs and L-shaped kitchens often need joints. A good stonemason places them where they are least visible and structurally sensible, usually away from the sink and hob and not over a dishwasher or other gap without support.

With veined marble or strongly patterned granite, it is worth asking to see how the template will sit on the actual slabs. Many workshops let you view the slabs or a layout so you can agree how the veins will run across joints and around the kitchen. This is one of the most important moments in getting a beautiful result.

Preparing for the templating visit

A little preparation makes the visit quicker and more accurate:

  1. Make sure all base units are installed, levelled and fixed.
  2. Have the sink, hob and tap on site, or at least their exact models and installation instructions.
  3. Clear the tops of the units and give the stonemason access to all walls.
  4. Be available, or have someone available, who can answer questions about overhangs, edges and appliances.
  5. Mention any tall units, windows or radiators that might affect the worktop.

From template to installation

After templating, the workshop cuts the slabs, makes the cut-outs, shapes and finishes the edges, and prepares any upstands. On installation day, the pieces are carried in, set on the units, levelled, joined and bonded. Undermounted sinks are fixed, joints are filled and coloured to match the stone, and the surfaces are cleaned and, where needed, sealed.

The quality of the fit depends heavily on the quality of the template. A careful template saves time later and avoids gaps along walls, misaligned joints and openings that do not quite fit.
