Thanks all and the answer is no, Greg!
Steve, I couldn't use the shower kit system but wished I could. Check the specs on the kits. They have set dimensions for the drain locations and if yours falls outside of those dimensions, you cannot use their kits. Of course, mine was not even close...
Those shower systems are 'da bomb' though. Waterproof, not having to slope, no pan, able to use a square drain. Sigh......
I could not readily get the 'regular' waterproofing membrane at a reasonable price but could get the uncoupling version locally. The whole thing including the banding was right at $200 and the shower is now completely waterproof. That benefit alone was worth the extra expense.
