Many thanks to all of the contributors. Your answers have been extremely helpful and I have avoided steps that paint stores have suggested.

there is nothing unsanitary or unclean about a properly built and maintained tile shower enclosure, but maintenance and cleaning are key. regular degreasing (with a detergent or soap), descaling (with a dilute acid) and sterilizing (with bleach or hydrogen peroxide) are key. almost universally, any mold and mildew issues are solely the fault of the owners ...

Things I would suggest you to look for is condensation in the ducts. This can occur when there is a leak of cold air in the duct work. This creates a heat exchange between the hot air outside in the ...
