I need to raise subfloor by 1 1/2 inch.

I am a first time homebuyer trying to undertake a fairly big project (in my mind). I am working on renovating our upstairs bathroom and our plumber just finished installing the drain but he had to install part of the drain above the floor joists (1 1/3 in at its highest point). I need to raise the subfloor by 1 1/2 inches to account for this but am not sure the best route. I was going to sister the joists and raise/level it or I was going to build a platform with 2x4s that would run perpendicular to the joists, but I’m not sure if there is a better way to do this. I only want to raise the floor in the shower and not the entire bathroom. Any advice or video links would be greatly appreciated! submitted by /u/Outrageous_Quarter49 [link] [comments]
