Trying to brainstorm costs/If can DIY or Should get a contractor. Basement bathroom water(from hot water tank) is ran through (what looks like 1/2"-1") flexible tubing, Curious if would be enough pressure given the diameter of tubing?, As well as drainage (possible to drain through the same outlet as the sink?) laminate over concrete covers the floor. Assume can just buy a all in one shower assembly/parts associated w/install and just remove areas of the floor to allow a exit drain and connect with the sink's/refill w/concrete? Is this project bigger than Im thinking or is it possible with a little elbow grease and good planning?
