The best way to secure in the slab shower drain

[Scaredycats]

I am replacing an old shower in the basement. When I removed the pan, the ABS drain had not been filled in. I need to level the concrete for the new shower base. What is the best way to fill it in. I was thinking about sand up to 2 inches and than use leveling concrete? Do I need to wrap the ABS in anything?

thanks

The box around the trap is normal. When you set your new pan, you can fill the rest of the void between the slab and the pan with mortar. I prefer to lay a sheet of plastic over the mortar so it doesn't adhere to the pan just in case it needs to be pulled.

Assuming a quality constructed pan with reinforcement, A pan fails most of the time due to flexing over that entire 60" span. A small span of 16" isn't a problem.

The shower drain will be lower than the floor. You need a place for the drain there.
