How can I stop toadstools growing in my bathroom?
Wow….you do have a damp problem! Toadstools aren’t growing only because it’s damp but also because of excess mold spores in the room. Open the room a little during the day while you give the whole room a diluted bleach water scrub down to kill the mold spores. You (if owner) or landlord can install a ventfan/heatlamp combo that you can run during shower time. If that isn’t an option a dehumidifier may do the trick. There are many that can fit your budget. If you are getting headaches from time in the bathroom you may also have a serious problem with black mold (staph) Have a sample analyzed so you know what you are dealing with.
