Secure a vanity top securely and stably

When attaching a vanity top, the weight of the sink or sinks must be used as the most important decision criterion. Apart from the dead weight and the plate material, leverage effects due to the type of installation must also be taken into account. Wall mounts or a load-bearing substructure provide the necessary secure hold.

Materials and weights

From the weight of the selected material of a vanity first hints on the appropriate attachment arise. Most acrylic, wood, plastic and metal finishes have a moderate weight of less than five kilograms per square meter. Natural stone, concrete and ceramics can weigh ten kilograms or even more per square meter.

The same goes for the sinks. Commercially available sinks made from the "light" materials weigh between six and 15 kilograms per piece. They include most:

  • Mineral casting variants
  • acrylic forms
  • wood finishes
  • stainless steel basin
  • copper basin

Heavy materials generate dead weights of up to 60 kilograms per washbasin. Typical materials are:

  • ceramics
  • (Steel) Enamel
  • natural stone
  • real glass
  • concrete

The range of weights of the washbasin to be fixed ranges from acrylic panels and basins with a total weight of ten kilograms to natural stone slabs with matching basins of one hundred kilograms.

Total weight determines the type of attachment

In general, when mounting a washbasin with a total weight of over fifty kilograms, additional lateral breakpoints or a viable underbody scaffolding should be planned. The exclusive attachment to the rear wall is not enough. The same applies to the so-called dry construction of the washbasin, in which the weight is supported by a multi-purpose plate.

If, in principle, the washbasin is to remain open under the panel, supporting cladding columns may be a less conspicuous optical alternative. They not only carry the weight of the respective sink, but let the not really attractive siphon "disappear".

Level assembly and water bead

More important than other tabletops is the precise alignment of the vanity top when mounting. Since a washstand constantly comes into contact with splash water, an unwanted slope to the wall must be avoided. The backwater risk can also be eliminated by a special design of the vanity top. An incorporated and circulating water retention bead is available in finished products or may be taken into account when self-assembling the vanity top.

Tips & Tricks

When buying angle profiles for the rear wall mounting, you must pay attention to the load capacity of both the metal brackets and the wall screw connections. If in doubt, ask.
