I was also in EVERY bathroom suppliers, plumber suppliers etc. Exhaustive search and our conclusive experience was that Chadwicks is the best. They have a great deal on Ideal Standard bath plus screen plus other stuff for about 550, its a P shaped bath so maybe not what you want. There is also an ideal standard toilet for about 200 all in that is plain and simple.
Re taps and showers etc, we went with Reuter Bathrooms in Germany. The Hans Grohe stuff there is really cheap compared to here and its top quality, we're delighted with our new bathroom. We found Tubs and Tiles very expensive too, although we found a sink in there for 80 euro that is really nice, and the lad took 20 euro off without being asked so do some bargaining!!
