The plasterboard must be stable, suitable for damp conditions, waterproofed and ideally reinforced with mesh.

Detailed answer

Plasterboard in a shower enclosure must be stable, suitable for humid environments, and properly filled. The board alone is not enough – reinforcement tapes, high-quality filling, priming and waterproofing in wet zones are essential. If the structure flexes or the joints are weak, microcement will not save it. We recommend quality filling and the use of high-quality reinforcement tapes.

Common mistakes

  • underestimating waterproofing and connection details
  • incorrect slope or drainage solutions
  • insufficient sealing of high-stress areas
