I have successfully removed the black mould and a dehumidifier does help to dry out the damp bathroom plasterboard wall after showering, however I am still experiencing a lot of condensation when I take a shower, despite a 4" humidistat fan. My electrician advised this size fan should be adequate, however he did mention that a 6" fan would be more powerful. In your opinion, would fitting a 6" humidistat fan be more successful in removing the amount of condensation or would this be a total waste of money?
I also have a folding shower panel which drips down onto the wooden floor, thus causing damp under the floorboard - is there any way I can rectify this, as far as I can see it is the piece of rubber which is attached to the bottom of the shower panel which doesn't quite keep out the water.
hi, my view on fitting a 150mm fan is that you get approx 50% more extraction, if the condensating moisure was marginal then it may improve the situation but i dont think it will make much difference. if you cant improve air flow tby maybe opening a window and some warm air movement you may have to consider tiling to protect wall surfaces. your shower panel may need a new seal or the panel may need adjustment. try and keep the panel in the bath slightly. if the seal is worn you may be able to turn it around.
