Wet area

A wet area is the collective name for spaces where water is used: bathrooms, WCs, showers, kitchens and laundry rooms. In Turkish practice these are called “ıslak hacim”. They are more than tiles and sanitaryware. Underneath sits an unseen layer of waterproofing, sloped screed, drainage pipework and ventilation.

What matters in practice

Waterproofing is the critical issue. The floor and the lower part of the walls, especially around the shower, are sealed before tiling, and corners and pipe penetrations are taped separately. The floor is laid to fall towards the drain. Plumbing planned for easy maintenance, with service shafts stacked above one another, reduces damage over the life of the building. Mechanical extraction or a window removes moisture and prevents mould. Code and standard requirements vary by project type, so they should be stated clearly in the construction drawings and specification. Stacking wet areas floor over floor simplifies services and lowers the risk of leaks into dry rooms below.

Visualizing wet areas

Bathroom and kitchen renders bring together demanding materials: ceramics, glass, mirrors and chrome. If reflections, refraction and grout lines are off, the room stops being believable. There are practical suggestions in bathroom rendering tips.
