I'm renovating my 1972 house bathroom and just finished leveling the floor joists. Because I sistered and leveled the joists, the existing wall bottom plates are now slightly lower than the top of the joists, so they won't provide support to the edge of the new subfloor. I'm trying to build this floor as solidly as possible before tiling.
I'll be installing 5/8" T&G plywood, Schluter Ditra Heat, and 24"x24" tile.
Along the left wall, the distance from the edge of the leveled joists to the bottom plate varies between about 5/8" and 1". Since the bottom plate is lower than the joists, the plywood edge won't have full support there.
Would you add a ripped strip of blocking or nailer flush with the top of the joists along that wall, or is this small unsupported edge acceptable?
Also, should I add more blocking anywhere around the perimeter, or does the framing look sufficient as it is?
Thanks!
