You only use you bath the brush you teeth? The way I look at it is then (why did you buy a rv with a full bath?) I use by bath in my rv the same as home, as it has a three place room, "shower, sink and toilet" I know a lot of folks will not use the oven (I do) but the bath this is the main reason I have a full rv, as to not have to use public bath rooms, as so many are nasty, and I have enough health issues don't need any more. But to all their own I guess.
