Plasterboard Selection Guide for the Bathroom

Plasterboard in the bathroom can be a very useful solution for creating walls, ceilings and compartments. Here are a few golden rules to guide your choice.

Plasterboard is one of the most widely used materials in light construction, especially in the bathroom, because of its many properties and construction advantages. A perfect compound for creating corners, partitions, niches and false ceilings, plasterboard is extremely practical and comfortable, in fact it allows you to design the room to your liking, a fundamental aspect during building renovations. Let’s see how to renovate the house with plasterboard, particularly with regard to the renovation of the bathroom and what type to choose, how to use it and what thickness to prefer to obtain an effective result and great effect.

What is plasterboard?

Plasterboard is a material composed of treated plaster, reinforced by two sheets of cardboard that serve to make it more solid and robust. The use of this material is very old, in fact it was already used at the time of Ancient Egypt, although it was a different mixture. Modern plasterboard was invented in the early 1900’s in the United States, but in Italy it has spread especially from the ’60s onwards, considered at the beginning as an economic fallback for those who could not spend much. Today, on the contrary, this material has been revalued, assuming a fundamental role in construction and renovation, thanks to its many properties.

All the advantages of plasterboard

Plasterboard is often chosen in the construction and renovation of homes, as it has a number of particularly useful qualities:

  • island from noise
  • guarantees good thermal insulation
  • is moisture resistant
  • it is water-repellent and impermeable to mould
  • is rather cheap
  • can take curved shapes and make arches
  • it is easy to assemble and disassemble
  • is strong enough if reinforced

One of the most popular uses for plasterboard is the renovation of the bathroom, an environment where this material can find various locations, depending on your preferences:

  • shelves can be made
  • can form partition walls
  • you can create corners
  • can be used as storage compartments
  • you can build false ceilings
  • can be placed in complements and cabinets
  • you can structure the panels to take a shower

Which plasterboard to use for the bathroom?

There are different types of plasterboard on the market, but the material chosen for the bathroom must respond to a precise quality: reject moisture in an excellent way to avoid unpleasant inconveniences, being placed in a room of the house where hot water and steam make the area exposed to moisture. For this reason there are specific varieties for the bathroom, which are subjected to technical processes to increase their resistance to moisture. For example, there is a special quality of plasterboard available on the market, the hydrophobic sheet, a water-repellent material that repels water and blocks its passage. Green plasterboard is also widely used in wet areas such as the bathroom, or in wellness areas of wellness centers, for its outstanding insulating properties and discreet thermal and acoustic capabilities. Easy to handle and quick to assemble, it lends itself perfectly to concealing areas that are not aesthetically pleasing, such as systems, pipes and ceiling beams, which would be best incorporated into a false ceiling.

How to choose the thickness of the plasterboard

In the same way as in other rooms where it is used, plasterboard must have a thickness defined according to its intended use. This material, not being supported by concrete, needs a metal support structure, a system of galvanized aluminum frame on which to leverage for greater strength. The function of the part made of plasterboard, which could be that of a wall or a simple compartment, determines the thickness that corresponds to that of the metal profile that supports the plasterboard itself. A partition and soundproofing wall generally has (and the bathroom is no exception) a thickness of about 2 cm, consisting of two plasterboard sheets and a central part covered with insulating material. If, on the other hand, we talk about a space or an interstitial plasterboard, which serves to create corners and divide the room, the thickness can decrease without any particular problem, as it is not the wall that divides a room from the adjacent one.

A false ceiling, on the other hand, does not require such a high thickness, in fact it is usually enough just a single centimetre. It should also be noted that the thickness may vary, or increase, depending on whether there are cables or systems to hide, pipes and other elements that may affect the wall or sliding door, but for panels the standard size is from 1.25 to 1.50 cm. In conclusion, contrary to what was once believed, plasterboard panels and walls are a useful and strategic solution for shaping the structure of your bathroom, finishing rooms, ceilings and cavities in a fast and reversible way. The important thing is to choose a material of the right quality, which can adapt to a particular environment like this. To be sure of not being wrong, it is preferable to always contact a company specializing in renovations. An expert in the field will be able to advise you not only on the most suitable material, but also to carry out a job in a workmanlike manner.
