Andre knows his stuff. If you're tiling on floorboards you need to sort the plumbing out first and test it as you don't want to have to break the floor up and redo it if there's a leak when you're done. The best kind of plumbing is solvent seal, you brush the solvent into the joints and it melts everything together giving you a watertight seal. And if it gets cold in the winter use plastic pipe for your feed too as it won't burst. Also fit isolator valves to all your incoming stuff where you can get to them easily, sink, ti=oilet, bath/shower etc.
Get eleven mil (half inch) OSB sheets or plywood and cut them to the size of the room. Draw a six inch square grid over the floor surface and at every cross put a one inch screw in, so the surface is screwed down every six inches in every direction. Then make sure you use flexible floor adhesive and flexible floor grout.
