Routing MVHR ducting through stud work

[jayc89]

I need to route 4x 90mm ducts through our ensuite stud wall down to the ground floor. I have two options;

 

- 6x2 studs, used to brace the wall mounted toilet, vanity units, used for recessed shelving etc, but is at the furthest end of the room, so will add an additional 5m to each duct run

- 4x2 studs, used for the partition wall between the ensuite and wardrobe. More central in the house, so smaller duct runs, but technically the 4x2 is 89mm thick, so it will be a squeeze getting the ducts in (and no room for acoustic sound batts, either...)

 

I'm leaning towards the former and just accepting the longer runs. Any other suggestions?

I love good soundproofing between rooms, so I'd go for the first. Unless there are other acceptable options - planting some timber of the 4 x 2 studs to give more space, putting the ducts in a boxing, etc.
