curbless zero threshold shower

[sec1939]

remodeling our bathroom and wish to replace existing shower with a curb to a curbless or zero threshold shower. Looking for advice, tips, suggestions. I prefer to have some type of drop in pan/base verses a tile base. Approx size 60" x 40"

This is interesting as some day I want to have a shower much like that.
