We’re currently mid-project, it looks like once absolutely everything has been accounted for the final total cost will be £10K.
We’ve had the following done and our room is around 3.5 x 2.5m:
Wall to floor and floor tiles removed.
Walls replastered in places, all walls skimmed. New s-profile coving.
New subfloor and lvt laid.
Quadrant shower fitted and tiled.
Half-height wainscot around all the room apart from the shower, inc oak window sills and oak capping.
All painting and decorating.
New lights x 4, including removal of pull-cord switch to a rocker switch outside the bathroom.
New de-mister and light-up mirror.
New extractor fan.
New radiator (which has been moved to the other side of the room)
Plumbing in of freestanding bath, toilet, shower and vanity unit.
We went for mid-range stuff (Burlington).
It’s been a lengthy process, however. We’re now coming to the end of week 3 and still not finished - the end is in sight though.
We’ve had separate workmen, each specialising in one area for each part. So, a tiler doing the tiling, a floor fitter doing the floor, a joiner doing the wainscoting, an electrician doing the electrics, a plumber doing the plumbing, a decorator doing the painting, a plasterer doing the plastering etc. I believe you get a much better end result that way, but be prepared for it to take slightly longer.
