we are exploring a remodel of our bedroom/mst bath. Our house is on a slab, has hydronic heat, and we want to move the bath (entire) about 15 ft. All the discussion about "trenching" and jack-hammers has me concerned. Isn't there an easier way to move the plumbing...such as over the slab and under a false-floor. THere seems like there has to be an easier way??? Thx so much - and sorry to ask rookie questions.
