Hi John,
Did a bit more research on ACO linear drains at exit and found the flowrate specs for the various drains and heads of water. Looks like minimum of 6 gpm on 36" shower drain with no head and around 8.5 gpm with 0.2" of head. So I would think with only 2 shower heads at 2.5 gpm there should be no problem especially if you lower the linear drain a bit below the tile level as you mentioned previously and then maybe a bit of dry side slope. I will probably try to fit in a wider shower stall, even if it is a few inches more say to fit in the roughly 40" drain. That'll also give me an additional 10% of flow capacity.
Have you had any better success with any specific grate design in applications like this? They all seem to look good and I do like the lit drain option if it's not too expensive an option.
