In the Building a Home Forum and the Remodeling Forum, frequently when there is not a full bath or at least a shower on the first floor as a means of planning for exigencies and/or the future, they are told it is a good idea, if not an actual necessity.
Here one exists and they are being told to take it out.
If it's not there, you need to have one, If it is there, you need to take it out.
So goes Gardenweb.
I don't really care one way or the other, that much, but it is interesting to see this phenomenon in action.
