Thank you for taking my question. I have a long narrow half bath (only 4'2" wide) I would like to turn into a full bath which requires moving fixtures. Due to limited space, I want to install a 32"x32" shower in the toilet space, move the toilet in the sink space and shift the sink in a new space along the same wall. I do not want to tear up the concrete slab bathroom is on so I would like to buildup the shoer and toilet area of the floor with trusses to run the drainage pipes. Is this possible? Also, how do I extend the toilet drain to new location?
