recess the shower and use the schluter. Im in the process of remodeling by master bath, im not going curbless though. it would be better, but i cant really recess the slab as two of the walls in the shower are exterior walls. It would be too much work. But how I would do a curb less for sure. Just dont put the tub and the shower drain in the same room beside each other. that is just weird. I dont get it.
