Recessing subfloor with trusses

I'm remodeling our master bathroom and would really like to do a curbless shower with linear drain. I'm leaning towards using an ARC shower pan but need to recess the subfloor between the trusses in order to keep my floor height within reason. The shower pan is 36"x48". My trusses are 16" OC and 12" OC varied.





My question is, what would be the best way to add blocking support for the subfloor to the trusses? Has anyone used the Ebbe America or Wedi Fundo Ligna subfloor hanger systems?

I would cover the sides of the truss with plywood and then add the 2x4s to support the floor.

Nail the plywood into the top and bottom chord of the trusses? And then nail the block through the plywood into the top chord of the truss?

Tack the 2x4 in place and nail thru from the back side of the plywood.

That will be strong enough through the plywood?

I would think so. Add floor glue to everything.

A few years ago I did a handicap shower with floor trusses being an issue. Schluter makes a curbless shower pan that is 1 1/2" high. Then they make a tapered piece that butts up to it that starts out at floor level and tapers up to meet the 1 1/2" curb. It does this over a 16" width. It worked out well and allowed for a hefty person in a wheelchair to be rolled into the shower. The main shower area was 4' x 5', plus the 16" ramp area.
