How to measure for a made-to-measure vanity top

How to measure your bathroom for a made-to-measure vanity top, and how to enter the numbers in the configurator. You will see how to measure a niche from wall to wall, why you take about 4 mm off the width for the silicone joint, how to check whether the walls are square, and how corner shift, fillet and chamfer work.

0:00 Sizes in the configurator

In this tutorial: your vanity’s dimensions. How to measure at home, and how to enter it in the configurator.

Everything is in millimetres, and every change shows up in the 3D model straight away.

There are two ways to set a size: drag the slider, or type the exact number.

0:23 Measure your space

Before you enter anything, measure your space. Width runs from wall to wall. Depth runs from the back wall to the front edge of the top.

It helps to mark the height on the wall with painter’s tape. Comfortable heights are between 820 and 980 millimetres, and 900 is the most common.

0:44 Measure the width and leave a gap

Don’t measure the width in one go: a tape that bends gives you the wrong number. Measure to a round number, say 1000, then measure the rest from the other wall: 426.

Add them up, and take off one and a half to two millimetres per side, about 4 in total. That gap is filled with silicone later. So: 1000 plus 426, minus 4, makes 1422.

Without that gap, the top won’t go into the niche. With it, it slides right in.

1:20 Tops with a thick front edge

One more thing: if your top has a thick front edge, it can only go in from the front. Tilted into the niche, its diagonal is longer than the space between the walls.

1:32 Enter your measurements

Now enter your numbers: width 1422, depth 500. Type them for millimetre precision, or use the sliders for quick changes.

1:43 Walls that are not square

Walls are rarely perfectly square. Mark the depth of your top on the side wall with painter’s tape, then check the corner at both ends.

Hold a carpenter’s square in the corner, or a shelf from a cupboard, and measure the gap at the tape. Here, it’s 2 millimetres.

Enter that as the shift for that corner. Now the front edge is 2 millimetres longer than the back.

A negative shift does the opposite: the back becomes wider than the front. That only works in a corner with one open side. In a niche, the top won’t go in.

2:18 Corner shapes

Fillet rounds a corner. Pick the radius from the list, and the model follows.

Chamfer cuts the corner at 45 degrees. The slider stops at the largest chamfer that still fits around the basin.

And Sharp gives a plain, square corner, for a top against a wall or on a cabinet.

Measure twice, order once. In the next tutorial: the sink.
