I am looking at some properties so I have limited access at the moment, that would come with second visits to the properties. A few of them may be suitable but lack a downstairs loo. One of them has a large utility that could be used.
At the moment I have to assume it is a normal wooden floor (not concrete) so would have access to under floor area. As there is a wash machine in utility room I also assume there is a waste pipe and water supply.
Now would I require a larger waste pipe for toilet (I think yes) and would this be relatively easy for a plumber to connect to existing toilet waste? I am probably capable of building the partition wall and door so I would do that. Would need plumber to install hardware.
Not counting the cost of hardware and if there are no major issues what would be a ballpark figure (scotland) for the above plumbers work. Would I also require planning permission assuming no structural change apart from adding a partition wall. If so would I need professional drawings of some kind?
Any guidance appreciated. I am just trying to budget at the moment £1k £3k £5k I just dont know.
