I've recently completed a new bathroom and we're having condensation issues.
The old bathroom was the same layout with the same extraction which is through a light above the shower rain head. The significant difference between the old and new bathroom is one wall is fully tiled with glossy porcelain tiles whereas previously they were travertine. Other difference is that the walls are painted with proper bathroom paint as opposed the the previous matt emulsion.
The condensation is visible as shiny water trails on the walls. So far its not causing a problem, but it will eventually.
Showering with the windows open makes no significant difference. I've increased the size of the extractor fan from one that was moving 130m3/hr to a fan that should produce 245m3/hr through the same 100mm flexy duct. The extraction point is directly above the shower head and that has made quite a bit of difference. I can see from a smoke match that the fan does catch a lot of the steam. The mirrors no longer steam up but the shiny trails on the walls are still there.
Any further suggestions? Turning the heating on fixes it, but that's not really an option for this time of year.
