Humidity causes mold and is bad for your clothes, drapery, mattresss, etc… Ideally the bathroom would have a strong exhaust fan.
All bathrooms should be on the side of the house with a window to evacuate the smell. A bathroom should never be smack in the middle of the house.
I agree that the secondary baths should have vanity areas for the girls. These days, a new house should have a bathroom for each bedroom.
Some mc mansions now have snoring room so the snoring spouse can decamp to that smaller bedroom in the middle of the night.
Come on, humidity is a problem in San Diego? Most masterbaths have at least a window or two + exhaust fan. I have to agree with cyphire. Having the walk in closet inthe bathroom is very convenient.
What irks me is having a laundry room upstairs. Every time i go on a long trip, I'm always leary of a washer hose breaking and flooding the house. That's why I end up always turning off the washing machine waer supply lines before vacation. Never understood this. Are people that lazy to go downstairs to do laundry?
