Replacing tile floor in small (6x5) bathroom with tub, on 2nd story of a condo. After pulling tile, noticed some water damage in corner by tub, on the subfloor and the floor plate in the wall (looks like a tile was loose, and kids getting water out of the bath leaked into subfloor). Took out the rot, appears the 2x6 floor plate only rotted less than a 1/3 way back, and just bottom side, and length wise less than a foot. First question is, do I need to have this replaced? The above joists are perpendicular to the wall, so it may be load bearing (but it’s a small length of wall compared to the two long load bearing walls). I’ve seen some wood epoxy products for structural fixes (e.g. conserv epoxy, Abatron epoxy, PC Woody), would these be worth it, or is it fine as is?
EDIT: Learning a little more, and looking in the attic (this bathroom directly below attic level), the roof is a manufactured truss assembly. This (may) suggest the internal walls aren't load bearing. Which could mean it wouldn't be too bad to remove a portion of the 2x6 floor plate to replace.
Second question, I’ve looked into replacing subfloors, adding 2x6 blocks to support the replacement subfloor piece. I usually seen these done with floors with joists, this has floor trusses, anythjng different I should do?Also, there is definitely part of the subfloor under the floor plate that should be replaced. What is the best way to do this?
