Stud walls for bathroom

[Sheepshanks]

Hey, I'm looking for some advice on a DIY project I'll be starting soon. We're looking to start refurbishing our bathroom and there are a few things I need to solve beforehand.

The walls are non load bearing paramount boards covered in tiles. The walls are all a bit of a mess so I'm going to use the opportunity to replace them with stud partitions. The opposite side of one of the walls has already been decorated so I'm hoping to bond in the stud frame for this one. What is recommended regarding fixing the sole plate for the stud wall? Should I rip up the floor boards and fix the sole plate to the joists/noggins or simply fix on top of the floor boards? I do need to rip most of the flooring up in the bathroom as there is a slight slope I need to investigate and potentially fix some kind of shims.

I appreciate any advice that can be given.

Thanks

The sole plate debate regards fix to joists or floor boards rests with - do/don't I need access beneath once the stud wall is built. If you have all services cables pipes wastes in place, then fix to the floorbards.

Slope will depend on how you furnish the bathroom, i.e. will there be long fixed rigid units all the way to the floor? Will it work favourably for a large shower and slope for the waste etc.

Thank you for getting back to me.

Our current bathroom has been really shoddily done so the whole floor will likely be coming up to reveal the joists and make re-plumbing easier. The floorboards currently run under the paramount board walls and over the landing. I'll likely have to lift this side too as this is where the main run of central heating pipes are. They're currently microbore so we'll be having them replaced with 15mm. With me lifting both sides, do you think it'd best to fix the studs to the joists? I guess with this approach, in the future we could lift the landing floor without disturbing the bathroom if needs be.

We're still undecided on furnishing for the bathroom. The slope is a weird one. It seems to start from where the middle to rear joist span starts. Until I lift the floor I won't know for sure but I think it might bow as there's no cracks or signs of movement at the back where those same joists would meet the rear wall.

Thanks again
