Finally got my Onyx shower base picked up the other day, so I am starting to get ready to start on the shower install.
I have the typical 12" square hole in the concrete for rough-in. I will get the trap and related PVC pipe all connected, but once that is done, I will need to fill the hole in somewhat. Onyx wants the hole to be no more than 6 inches in diameter.
What's the best way to fill in the hole?
From what I have read here and other sources, I was thinking of filling with sand for most of the hole, then using deck mud for the rest of the way. I would place a pipe or something over the drain pipe, so that the final hole size would be about 6". This would give me a little play in the drain pipe to make attaching it to the bases easier (I'm using a brass Oatey no-caulk drain designed for preformed bases).
Is my thinking correct? Is deck mud the correct thing to be using? If so, how thick should the deck mud layer be?
Bonus question: I have been thinking about installing grab bars. What are your opinions on grab bars in the shower? Like maybe just one at a diagonal. I get funny looks when I ask this as a healthy 25 year old, but to me it just seems smart.
