Hi - I’m going to be building a new internal wall to partition between two bathrooms.
To the right will be a shower wall, to the left side will be an in wall toilet.
Existing wall has 90x35 studs. My new wall will be 90x45. There would be plumbing (water feed pipes) needing to run through both walls to service the shower/toilet/nearby vanities.
In the images I’ve laid out a demonstration of the exact position for the bottom plate of the new wall. As can be seen, an existing stud lines up slightly off centre to my new bottom plate position.
The additional images show an example of a potential t-intersection connection assembly - with two 90x45 timbers placed flat side outwards, perpendicular to but right up against the existing stud. These would run all the way to the top. This would allow sufficient timber in each corner to attach wall sheeting and also the cavity behind each piece could be insulated.
My solution for fixing would be toenail/pocket screw/nails into the top and bottom plates and also a few angle driven into the existing stud.
I also need to ensure this is compliant with building codes (AS1684).
Would this wall connection be effective and meet building standards, or is there a better way to make the connection?
Particularly, are there any stability/flexing/movement issues to consider with fixing the timbers flat side outwards for wall sheeting attachment (either villa or aquachek) , given at least the right side wall will be tiled nearly to the roof for the shower?
thanks
