Looking at a 3 bed semi with downstairs bathroom and a small upstairs loo. Agents haven't measured the loo but we measured in a Heath Robinson arm span way and reckon it is approx 1.3m x 1.6m. Looking at changing the door so it either slides or opens out into the hallway and installing a very small corner shower unit in the (facing you) left hand corner of the room, slimline loo in the (facing you) right hand and a small sink on the end of the wall next to the shower (area currently hidden by the door opening into the room). Has anyone done anything similar in a very small space? We could at a push steal some space from the bedrooms next door but that increases cost considerably. How small is too small?
