We advise against using stone carpets in the direct shower area. The reasons for this can be found in the basic structure of the floor and the wet room. Just as the tile adhesive under a tile does not form a completely flat surface without air pockets, pores also remain underneath a sealed gravel floor.
If, after years, a silicone seam leaks and water from a fitting, for example, penetrates between the wall or floor covering and the seal of the building structure, the transparent pore seal reacts with the water and forms white stains. As these occur underneath the seal, they cannot be wiped away or removed by drying.
This is why insurance companies do not classify stone carpets as suitable for wet rooms and do not replace such coatings in the event of damage. We therefore recommend microcement coatings for showers. With these, there is no water-bearing layer between the floor covering and the substrate, so there is no risk of moisture penetration. Due to the many customization options for microcement, it can also be combined with marble and quartz gravel.
