Soapbox: Wall-hung sanitaryware offers perfect solution to bathroom condensation, says Abacus

A lack of understanding by the bathroom industry of what causes condensation is leading to mould growth and rot in bathrooms.

One reason for these problems is due to condensation on toilet cisterns and water pipes. This is particularly prevalent in cold weather when the water entering the cistern is at a much lower temperature than the bathroom which often has a warm, moist atmosphere due to showering and bathing.

One way of overcoming these condensation problems is to install a concealed wall mounted cistern. Unlike a traditional ceramic cisterns, which acts as a thermal bridge between the cold water and the warm room, these modern options are made of plastic which acts as an insulator.

Concealed cisterns have the added benefit of the further insulation provided by the surrounding cabinet or because they are within the wall. This results in an extra thermal break between the water and the room. 

Another advantage of wall hung sanitaryware is that the pipes leading to it come from the wall so are insulated rather than, as is the case with basins, running up a pedestal or directly from the floor which means they are uninsulated and vulnerable to condensation. 

Condensation is also an issue with wall surfaces. Here Abacus Elements and EPS tile backer boards are a good solution as they not only waterproof the bathroom and improve U-values but help cut down condensation by preventing thermal bridging from cold external surfaces.

In all bathrooms, extractor fans are vital in order to remove moisture. These should 'overrun' so they continue to work for some time after the room has been vacated.
