Full pop was around $700.00 CAN my cost, or around $50.00 USD with the exchange these days.
It's a neat little rig. I got the offset drain to accommodate floor joists and maintain visual center. Goes in with ABS glue and unmodified like regular schluter drains and comes with a prebonded kerdi flange. The outer trim ring is mortared in place inside the lower trough and has flanges bent to support the inner trim.
For this application we used a mortar bed (dry-pack, sand-mix, insert familiar jargon here). Floor joists were 2"x10", 16" o.c. over a 9'8" span. Notched the floor joists to 7 1/4" in the shower area, sistered with 2"x8" bearing to bearing and resheathed. Let us get the curbless with a nice 1/4" in 1.
Under the main floor is Ditra heat
