We have 5 bathrooms and when we buy another house one day I wouldn't want fewer than 5! Well, maybe if the kids were all gone, but with 3 kids and 2 adults, 4 out of 5 bathrooms are used everyday. The 5th bathroom is really the guest bathroom and it's on a different floor than the rest of the house (other than the guest room), but our laundry room is also on that floor so I actually am there a lot (of course!), so I use that bathroom periodically. Sometimes the kids too, as they play int he guest room a lot.
