Restoring the bathroom: 10 useful information


A well-executed and standardized operation is one that respects all the foreseen rules, between masonry works and installations, with specialized and qualified labor. And it is also the only way not to risk having to redo everything or even to have to block jobs.

  1. The surface of the bathrooms is also established by local regulations such as the Building Regulations and the Building Hygiene Regulations. In Milan, for example, a minimum length is not required. Still, the shorter side is not under 120 cm, and the surface of the room is sufficient to accommodate a washbasin, bathtub or shower, toilet, and bidet even in a single appliance. When changing the size of an existing bathroom and also when obtaining a new one, it is necessary to follow the values ​​provided for by these regulations, which can be obtained from the technical office of the Municipality.
  2. In some cases, the Regulations admit that the bathroom has no window, provided it is equipped with a device for activated mechanical ventilation; referring to Milan: when the house has an area of ​​less than 70 square meters and only one bedroom or when there is another bathroom that is naturally lit. If the home, then, is equipped with VMC, the bathroom can be blind.
  3. Many Municipalities prescribe that the environment containing the hygienic vessel is disengaged from the kitchen through a particular compartment (which can be anteroom, corridor, atrium), delimited by doors and windows. In the room, you can generally put the sink.
  4. In some areas of the bathroom, the water and electricity systems converge on the same wall: for safety, it is mandatory to comply with the regulations governing design and construction (such as the Cei 64-8 standard). Near the sinks, for example, the electrical outlets must be protected with a built-in differential switch.
  5. To have the walls as free as possible from technical components, it is often convenient to opt for floor plans where all the ducts are laid on the ground and partially use only the lower part of the walls. It is a viable solution when the room is wholly restructured because it requires the total removal of the coverings and substrates.
  6. Once the laying of the water and electrical systems is completed. Still, before restoring the foundations and applying finishes and coatings, it is advisable to take a series of photographs with pipes and cables. Having a real trace of the technical schemes made will prove useful over time, in the event of disputes, losses, failures, but also only if the systems must be expanded or extended.
  7. Bidet and vase placed side by side: a preferred arrangement because it is the most comfortable and aesthetically pleasing. You need 120 cm on the wall. When there is no such space, one is obliged to place the sanitary ware opposite one another, with a series of precautions: since the drain of the bidet must be connected to that of the vessel, it is necessary to guarantee the pipe the appropriate slope (1 cm for every linear meter); it is better to choose models with limited depth that leave more space between the two elements. There is also 45 cm in addition to 50 cm: compared to the standard size of 55-57 cm, you can earn up to 12 cm.
  8. In the bathrooms, the walls must be covered with waterproof, smooth, washable, and resistant material (such as ceramics, for example); sometimes, the legislation also establishes up to what height (in Milan up to 180 cm, so better inquire ). And the ceiling must be finished with a breathable product.
  9. Do you replace the sanitary ware? To limit the intervention, choose the new elements with connections to the systems compatible with the existing arrangements. Same for taps, tub, shower …
  10. To renew the aesthetics of the room without breaking or demolishing, the old floors can be overlapped with new ones, but by choosing slabs of stoneware with a thickness of only 2-3 mm, which are suitable for this purpose. For the walls, in addition to this solution, there is another one: unique products, such as waterproofing skim coats, can be used as paints to cover old tiles, provided they are intact, with excellent results.
