As with all home improvement projects the price depends on the design and extent of work required, as well as the size of the room. let's go through the different areas.
You need to first decide if you are prepared to install yourself or leave it to a professional. Unless you are qualified as a plumber, tiler or electrician we would advise to use tradesmen. In the longer run you will save time and money.
Either because of the age of the current room or your requirements to change to lighting and wall sockets, there could be sigificant electrical work. Things you may want to add to the room include installing a hair dryer, having sockets for shavers etc, including an extractor fan in the ceiling, and installing a power shower. This could cost around £300-500.
Tiling is more tricky than it looks, particularly if you want all tiles parallel with the same gaps and planned well in to the corners, including the cutting of smaller tiles in gaps. Floor tiles are an additional challenge given their increased thickness - cutting is difficult if you don't invest in quality cutting equipment, and again planning sizes and shapes to complete your area really needs an expert. Look at around £800-1200 (excluding tile costs) for a 12x6 floor area. In terms of the tiles used you could opt for ceramic to keep costs down but on the other hand an investment in marble can really set this room off.
A good part of the budget needs to be set aside for plumbing. Replacing the toilet with something more modern and efficient, installing a shower instead of your bath, and fitting need piping and taps to the sink are a few of the main areas. Expect £700-£1000 for a typical room.
Suites can be around £1000. But you can pay double this something a bit different.
A cost worth remembering when you are budgeting. There's quite a bit to remove and disposing of. The average cost for removing and disposing is around £500.

Price: £500-£600 (Walls), £300-£500 (Floor), excluding tile costs
