Bath-fitters (or similar) - redo entire bathroom? Floors/Walls/Sink/Toilet?

It would really depend do you want it repaired or replaced that is where the money would be going. Best to replace the toilet with a more efficient one but if the sink can be saved by putting a small cupboard under it I would do that... and they can redo bathtubs in a day they glaze it and it lasts a couple of years.
