Pinned for the idea. Not sure how much I like the extension over the toilet. If were to do, vanity top should be one piece, with no cut line. Also: Consider how much the extra counter space would be needed.
cardboard castle made out of cereal boxes and toilet paper and paper towel rolls...it all fits on a 8.5X11 sheet of paper so not too time consuming either...this is still unpainted so get creative and let the kids have some medieval fun
