Summary

Floors and walls in toilets, bathrooms, and similar wet rooms have
traditionally been made of inorganic materials (i.e., concrete, lightweight concrete and bricks clad with ceramic tiles).

Since its 1972 edition, the Danish Building Regulations have also permitted the use of wood and wood-based boards (e.g., plywood), on condition that the floor covering is watertight and water
resistant and that the walls are coated with a watertight surfacing.

These Guidelines describes in situ construction of floors and walls in wet rooms in dwellings and rooms with a similar pattern of use. Applications of the following materials and constructions are described: concrete, lightweight concrete, masonry, plasterboard, calcium silicate boards, chipboard, plywood, tiled coverings, PVC, paint applications, joints, and other similar elements. Furthermore, different ways of treating existing floors and wall constructions are described.

The specifications and solutions shown are recognised as
compliant with the requirements stipulated in the Danish Building Regulations.
