Ray, how would this work for the bedrooms?
Prewire to the ceiling of all three bedrooms and put an AP in the centre bedroom. The master and first bedroom would be one wall away. If no kids, put the AP in master bedroom.
Looking at the house plan, could you move the two bedroom doors to be next to each other and have two hall closets, instead of one long one? Might help to muffle toilet flushing sound into the first bedroom?
