Was looking at doing a curbless, but Freedom Shower offers a 61x60 pan with a 1 1/8 high threshold, so i think this is alot easier that a hot mop floor and way easier to install on top of a slab. Most codes require threshold of at least 2" above top of drain, so this should work. Does not need to be ADA compliant for my home. Has anyone installed one of these. The install instructions look straightforward, so wonder if any pitfalls to avoid. Thx!
