The family tackle five en-suite bathrooms, one for Graham and Sarah, and one each for the boys. They begin by installing under-floor hearing then take delivery of 178 different items required to kit out these separate rooms. When it comes to the tiling, Charlie and Raffey decide they want to do it themselves, so Sarah shows them her grouting skills. Things gets more tricky, however, when they try to shift a 400lb cast iron bathtub upstairs. Away from the build, the family learn about weaving rush seats and haymaking.
