It would not be to difficullt to put bath where toilet is now (wide bit to wall),
Move toilet to other end of bath extending soil pipe on outside wall, and put sink next to p shaped end of bath on wall, you could always put a narrow sink in 450mm if room is a bit tight. you could the put a towel radiator on long wall opposite bath.
in answer to your question on tiling it should cost about £20.00 per sq mtr for fitting ceramic.tiles. If you go for stone or porcelain, expect to pay around £25.00 per sq mtr.. Make sure he uses good quality adhesive ie BAL (from topps tiles)
What about the floor?
