How to take measurements – designing a worktop

Designing a worktop – the maximum length of a worktop we currently cast is 2.7 meters. Longer worktops should be halved by stove or sink openings in such a way that the cut-out for the stove or sink would be at one end of the worktop. A worktop with a cut-out in the centre is the most impractical as in this a case there are heavy weights (about 60-80 kg) on both sides of the cut-out, which affect the “thin” edges of the cut-out and pose a threat to the integrity of the worktop during transport and installation! The “thinnest” edge should not be less than 70 mm wide.

There is the option of casting a thicker worktop – a worktop with a thickness starting from 6 cm is sufficient to avoid problems during transportation, but this significantly increases the weight of the worktop (for example = a worktop of 2.5 m x 0.62 m x 0.06 m weighs 175 kg). In such cases, the worktop has to be divided into smaller sections, which again ruins the monolithic nature of the worktop.

Monolithic sinks in the worktop – monolithic sinks are cast directly into the worktop. It has to be kept in mind that, depending on the sink, this increases the weight of the worktop by 35-65 kg. As the thickness of the walls of the sink is 3-4 cm and the mould of the sink does not copy the internal radius of the sink, but is rectangular at the bottom, such a sink takes up quite a lot of space in the cupboard under the sink.

This is why monolithic sinks are more suitable for bathrooms, where the worktops are smaller and the purpose of the sink is simpler than in kitchens. In kitchens, the space is planned in detail and there are different technical requirements for the sink (draining dishes, overflow, little use of space).

About worktop measurements – where to obtain precise measurements – many furniture manufacturers and interior designers have already specified on their drawings the measurements of a worktop suitable for the specific furniture. Such drawings also specify the measurements and locations of the cut-outs necessary for sinks and/or stoves. The best solution is to send us these drawings and we can make the worktops accordingly.

If you take measurements yourself, it is necessary to observe the following aspects.

With long worktops that need to be divided the following has to be taken into consideration:

  • joining lines of cupboards, because it is visually better if the joining line of the worktop is on the same perimeter as the joining line of the cupboards;
  • locations of large openings (stove/sink) – it is advisable to leave these at one end of the worktop (close to the cut, but not closer than 70 mm);
  • width of the sinks and stove (subtracting the width of the opening from the width of the worktop, the remainder has to be more than 140 mm);

if there will be a faucet in the worktop, then an edge of at least 100 mm is necessary for fitting it in (the faucet itself will take up 40-50 mm); the precise locations of the penetrations for the faucets;
whether the worktop projects across the edge of the cupboard or is even with the cupboards – the door handles of the cupboards!

Sketch – the plan for the worktop may be sketched in freehand, but it has to be made sure that the noted measurements have been checked and comply with reality.

Extra-reinforcements for the cupboards – regardless of the fact that a 2.5 m worktop may weigh approximately 80-110 kg, depending on the openings in the worktop, it is not a problem for the cupboards as the weight is distributed between several cupboards.

Attention has to be paid to the weight in bathrooms where the bathroom cupboards are not placed on the floor, but are attached to the wall. In such cases, additional constructions are necessary and the material and construction of the wall has to be examined to make sure that it can sustain the weight.

A (wooden) base for the worktop is installed in case of thin plates typical of windowsills and if the thickness of the plate is less than 30 mm. In case of an ordinary 40 mm kitchen worktop, there is no need to install a base for the worktop.
