Upstairs toilet and basin. Maybe a shower too.

We want to add an upstairs toilet, basin and maybe a shower. Upstairs are two bedrooms they are in the "A" section of the roof if you know what I mean. The bedroom windows protrude out in a box section from the roof. I believe there would be room for a small bathroom area that could also protrude out from the roof on the opposite side. Indication of costing of this type of job would be helpful. Regards, Brent.
