However, in the last 12 months, I have built all manners of bathrooms in France (Brittany); from small to large, modern to country style, wet-rooms, and some custom designs with audio speakers, coving and Tadelakt walls and floors.
As a rule of thumb, 150 man hours would be a fair answer; this would include the following work to be completed:
Gutting out the bathroom suit, and removal of any walls.
Trip to the dump and shopping.
Stud work and first fix - Electrics and Plumbing.
Drylining and plastering.
New Evacs for shower, standard or wet-room style.
Installation of under floor heating and floor levelling.
Painting of ceiling and walls
Tiling floors and walls - English Tiler in Brittany
Grouting - Boring, but should look great if done with some love!
Detailing i.e. - wood panelling
Installing or building of storage spaces.
Fixtures & Fittings - Baths, shower screens mixers, sinks toilet, lights, fans etc.
Snagging.
