I decided to have my bathroom completely revamped a couple of years ago and investigated a few of the national companies who undertake the whole thing; removal of old fittings, replacement with new, updated plumbing and tiling. The average cost was £8000. Instead, I went to a local, independent and reputable bathroom shop; they reconfigured the layout to one that made much better use of the available space, helped me to choose fittings that I wouldn't have thought about, recommended different and better lighting and advised on a safer floor covering than tiles. They also arranged for one of their experienced plumbers/heating engineers to do the whole job. The price, including full length walk in shower, washbasin, toilet, shower screen, flooring, radiators, lighting and tiling, grab rail, taps and storage cabinets was £6000.
