Good Evening Dee.
The Freestyle Linear Drain from Nobel connects easley to 2" ABS or 2" PVC. You should order the one that fits your homes plumbing. The plumbers end will be over when he glues his vertical leg from the PTrap to the drain's body.
I would be looking for a skilled waterproofer and tile setter. I can help you find someone if you like.
You mention a zero threshold shower in a new home is the framing finished? Have you ran your HVAC, Electrical and Plumbing already?
A copy of the bathroom layout with an overlay of structural framing members and joist runs and spans would help me give you any further advice. There is a lot more to consider when building this shower you have than a little ABS glue and thinset.
I put the word out your looking for an installer in the North Augusta area...
Here is a picture of a cross section of the Nobel Drain your considering;
The Drain sample in the picture is made of PVC and the black pipe made from ABS you can order your Freestyle Drain in either material.
