Around once every 2-3 days but I have a little boy in need of target practice

Add his dad and his 2 sisters who need to learn to leave the shower AFTER getting dry and my dogs who get a bath every 2 weeks and shake the water on their fur up the wazoo... We have pretty clean bathrooms, but not because I like to clean that much, just because I have to
PS: Watch out for bleach: Mixing it with some other cleaning products creates a combination that emits deadly fumes. Seriously. never mix bleach with other cleaners.
