You could consider fixing schluter kerdi membrane to it which I believe is a popular system in north America

I think I should tell them I need a grout joint to at least use leveling wedges because of the amount of thinset needed behind these, what I consider large tile. The wedges keep a 3/16 grout line.

Yep I do

You need a grout joint because if you don't the tiles will leak . Also recommend using a thinner levelling clip than your joint width . So create joint width with spacers so levelling clips come out easily without chipping tiles .

Durock is only water durable and not waterproof.
You would be well advised to use Hydroban or RedGaurd as a waterproofing membrane over the Durock. This will give you a waterproof substrate on which to tile to.

If I end up finishing this job I will take everyones advice and do my best. I've done plenty of work for myself ok, but it is different when someone else looking over your shoulder is paying the bills.

You’ve already done more than most I’m sure, just by researching the project and all that it entails.
Come back let us know how you got on.

I will for sure, thank you very much. I hope it works out ok, whoever sets it, especially letting the house freeze for five months a year. The old melamine was perfect, just ugly.

I've decided to try a shower job on my own place first. Then make a decision to do my neighbor's or not. I have a small camp on my property that will be good practice and has almost the same situation as the people I caretake for. I'll keep my progress posted when possible.
