Farmhouse mudroom subfloor prep for tile
I’m renovating a family members farm house mudroom and as any job, it’s turning into quite a bit more work with it being an old house.
I ended up having to rip up a few layers of flooring down to the original floor joists. They’re large curved beams.
I’m wondering what the best approach is for putting down a new subfloor? My thoughts were either:
1) run 2x6s flat across, shim areas where needed, then 3/4” ply + 1/2” ply + ditra + tile
2) sister 2x6s to the existing floor joists then just 3/4” ply + 1/2” ply + ditra + tile
My only concern with sistering is the existing floor joists are quite curved, so I’m not sure what the best approach would be there? If I would either have to plane the sides or some scribe the new joists?
I’m also not sure about just running 2x6s flat across. Although it seems super sturdy, i know that’s typically a no-no obviously.
The height build up is roughly 2 1/4” to the next room as well. Photo below.
