Blocking Below Subfloor

blocking below sub floor
I had to remove a large section of weak, wet subfloor in my bathroom. I ended up cutting it out to the wall edge with an undercut/jam saw, then supporting as shown in the pictures. I have 3/4" plywood for the replacement subfloor, and I have supported a lot of the edges using 2x4 pretreated lumber with man 2.5" screws. Is this sufficient blocking to support a Schluter tile system once I install the plywood?

Also, how would I level everything between studs?

Thanks

Baring leaks I think you have sufficient framing. For a bath that always gets leaks I normally use 3/4" pressure treated plywood for the sub-floor. It won't rot unless the leak goes on for a very long time.

You need to check with your local building codes to see if they will accept 3/4" plywood for flooring. I live in Oregon and usually plywood needs to be 1-1/8" tongue and grooved for flooring.

I am not sure what you mean by this. Do you mean leveling between the joists? If you are referring to the joists, then the joists should have been installed level. If they are not level, then you will have to use shims on top of the joists to get them level.

You also might want to try posting your question on a "construction" forum like DIYChatroom.com or some other building forum. This forum is mostly about woodworking not home remodeling and construction.

I happen to have a little experience in building and remodeling home construction, but I am retired now and spend my time building furniture in my wood shop.
