Let's get started – step by step: How to cut kitchen worktops

The following instructions are for how to cut a kitchen countertop made of wood or a wood composite.

Important: Be sure to wear safety goggles and ear protection when sawing! Pay attention to occupational safety at each step to protect yourself and your health. You can find more important information in our DIY safety precautions guide.

Step15

Determine the dimensions of the worktop

Ensure all base cabinets are straight with a spirit level or line laser. Place the tape measure or folding rule (or line laser with integrated tape measure) on one side and measure the entire length. We recommend using a digital laser measure for the most accurate measurements.

Next, measure the depth to the wall. Add 2-3 cm to the determined value so that the cut kitchen worktop protrudes slightly after you have assembled it.

Step25

Cut the basic kitchen countertop shape

Using a handheld circular saw with guide rail, you can make precise, straight cuts — perfect for cutting a kitchen worktop with accurate dimensions.

 

Place the wood that is to become the worktop on two wooden trestles with the bottom side up and transfer the measurements with a pencil. Then cut along the lines with a handheld circular saw. This is considerably easier with the help of a guide rail. Start with the long side and check the fit of the worktop by placing it on the cabinets the right way round.

Step35

Mark required cut-outs on the worktop

Thanks to the masking tape, you can sketch the measurements and make corrections, if necessary, to mark the cutting lines to the kitchen worktop precisely for all components.

 

Now place the countertop back on the trestles with the bottom side up. Attach the masking tape to the desired positions of the sink and stovetop. Place the sink and stove top upside down on the masked rectangles. Align the exact position of the components and their distances to the edge of the soon-to-be-cut kitchen countertop with a folding rule.

Trace their outlines with a pencil on the masking tape. Remove the components from the board again and draw the final cut line on the masking tape with an inner distance of 1–2 cm to the outer line (depending on the width of the supporting edges of the stove and sink).

Use an angle measure and a spirit level so that the lines are as straight and perpendicular as possible. You should now have drawn a slightly smaller square inside the larger, original square.

Step45

Cut the holes for the stove and sink

A man uses a Bosch jigsaw to saw out an internal piece from a worktop.

With a jigsaw, you can easily get into the pre-drilled corner holes to cut the cut-outs from the kitchen worktop. Thanks to the integrated suction function, you always have a clear view of the lines to be cut.

 

With a cordless drill/driver, drill four holes in each corner of the smaller marked square. These will soon be used to position the jigsaw blade. The drill bit should be slightly larger than the saw blade. Place the drill bit slightly offset inwards so that the drill hole ends with the inner dimensions of the cutout.

Once you are happy with the guide holes, insert your jigsaw into the first hole and proceed to cut your kitchen countertop slowly and carefully.

To maintain a clean straight line and prevent the countertop from moving while sawing, it is recommended that a second person hold the wood in place. Alternatively, clamps can be used. Do not try to support yourself on the kitchen countertop while cutting!

Once the cut-outs are finished, it is time to check the fit. Insert the sink and hob and make sure they fit securely before removing the masking tape. If the fit is not perfect, a multi-tool can make light work of precise adjustments.

Sand and seal cut edges

Heat and humidity, especially in the kitchen, can cause significant damage to wood. That is why you should carefully seal all cut surfaces of the kitchen countertop with silicone.

 

Smooth the edges of the cutouts with fine sandpaper. Proceed very carefully, especially with coated panels, as you don’t want to risk damaging the décor. Apply silicone and spread it over a large area with a spatula. All areas of the cut edge must be covered. When the silicone has dried, you can proceed to attach the countertop and insert the components.

 

Planning & background knowledge for cutting a kitchen worktop

Worktops are available in a wide variety of materials - from solid wood and laminate to stainless steel and concrete. Wood and wood composites have the distinct advantage that they are easy to work with if you want to cut the kitchen worktop yourself.

For all other materials, the cutting should be done by a specialist. This is especially true for concrete given that, depending on its length, a concrete worktop can exceed 500kg in weight.

Below you will find a few general tips and tricks that will show you the best way to cut a kitchen worktop.

Tips
Treating a concrete countertop
The industrial look of concrete is becoming increasingly popular in living rooms, kitchens and bathrooms. Still, using concrete does not mean you have to settle for a dull grey colour scheme. For a pop of colour, see our guide on how to paint concrete  properly.
 

Measuring the worktop

Before you reach for the saw, you must make precise measurements of your worktop. Take extra care with this, because inaccuracies not only affect the appearance, but can also lead to structural deficiencies. It would be a shame if the countertop warped or even cracked shortly after you installed it.

Begin to measure your countertop only after all the cabinets and other kitchen appliances have been installed and accounted for. Sketch out how your kitchen will look first and enter all measured values. It is also important to account for any unevenness in the wall before cutting your kitchen worktop.

Cutting a kitchen worktop for crooked walls

Walls are often a little crooked or uneven, particularly in older houses. A straight worktop is unlikely to sit flush against the average wall.

To transfer the exact trajectory of the wall to the wood, place the board atop the cabinets, flush with the wall where possible and stick masking tape to the rear for easier marking.

Determine the maximum distance of any uneven parts of the wall from the wood. Transfer this value to a scrap piece of wood and drill a hole at that distance, large enough to fit a pencil. Now, gently run the piece of wood along the wall, tracing the unevenness with the pencil in the hole.

The wall shape should now be transferred exactly to the masking tape. This is the best way to cut a worktop for an uneven wall so that it fits perfectly.

Fitting the worktop into a nook

If you want to fit the worktop into a nook or corner, it should not be cut exactly to the measured length. Wood expands with heat and so requires a small margin of space to expand into.

Measuring the cutouts for a sink or strove can be done in two different ways:

  • Measure: Measure the width and length of the components and transfer the measurements to the countertop using an angle measure. Now, draw another shape that is roughly 1-2cm smaller than the original lines. This prevents the stove or sink from simply slipping through the recess later.

 

  • Trace: Place the hob and sink upside down on the worktop and trace the outlines with a pencil. Again, draw another shape that is 1-2cm smaller on all sides. Some manufacturers also include stencils with their products, making it easy to trace and cut.
Tips
Using an old worktop as a template
If you just want to replace an old worktop, you can use the entire worktop as a template. This saves you the trouble of measuring from scratch.

Shortening an existing worktop

The best way to cut a kitchen countertop is with a handheld circular saw or plunge-cut saw and a guide rail. If you do not have a guide rail to hand, then a wooden slat will also do the job. Measure the distance of the saw blade from the guide edge. Secure the wooden slat or guide rail parallel with the cut line and secure with clamps. Proceed to carefully cut the excess length.

Cutting a corner countertop

There are various ways to join two countertops together at a corner. The easiest way is to simply place them side by side. However, you could also easily cut them in a much more aesthetically pleasing way:

  • Add a corner piece: Add an additional corner piece where the two countertops meet. This can be in the same style as the original countertops or different to add an interesting focal point.
  • Butt joint: Cut the worktops straight and push them directly against each other so that the head of one piece rests against the side of the other.

 

  • Mitre cut: Cut the two panels at a 45-degree angle to create a more stylised joint.

 

  • Create a panel joint: This is the most difficult but also most impressive-looking joint. Square pieces or ‘panels’ are cut from the edges of each countertop so that they slot together like a jigsaw piece. This is only recommended for experienced DIYers with the correct tools and equipment.

 

Sawing cut-outs from the kitchen worktop

You can create the cut-outs for components such as the hob and sink either with a jigsaw or with a plunge saw. You can prevent the edges from fraying or chipping by cutting from the bottom of the kitchen countertop or by applying masking tape to the top. There are also special jigsaws with chip guards. You can also use a saw blade with reversed teeth, but make sure that the visible side is on top.

In the case of worktops made of solid wood or a wood composite material, it is advisable to coat the cut edges with silicone after sawing or to mask them with sealing tape to prevent water damage. Be sure to use heat-resistant silicone for the recess of the hob.

Cost of cutting your own kitchen countertop

Of course, it is possible to have your countertop cut to size by a professional. However, doing it yourself can save significant costs on both materials and labour.

Estimating the cost of a new worktop depends on:

  • Labour costs
  • The size and finish of the countertop
  • Desired materials

In-house carpentry is typically more expensive than having the work done at a hardware store or kitchen studio. Here are some general prices you could expect to pay:

Work Involved: Price Estimate:
Hardware store Cutting the worktop to length Typically free of charge if wood is bought in the hardware store
  Cutouts £15–£20 per cutout
  Sawing or milling corner joints £30–£50 (depending on the type of joint)
Carpenter Uneven wall adjustments approx. £50
  Cutouts £20–£30 per cutout
  Sawing or milling corner joints £40–£70 (depending on the type of joint)
  Rounding corners £20–£30

 

If you want to have corner joints and cut-outs made in the hardware store, then providing exact measurements is important.  It is more convenient to have a carpenter handle this onsite, but it is usually more expensive.
