Setting basement shower

First, I want to thank Doug for all of his useful information and good-natured and helpful attitude - he's a great asset to this community...
I'm getting ready to set my basement shower (48" prefab drill-to-the studs type). I paid my plumber to preplumb for basement bath to discover that the shower drain didn't have a trap. I had to break up a 1' square section to get that resolved which has left that opening in the floor around the drain pipe. I plan on pouring concrete to cover the pea gravel which is about 4" from the top. While I'm at it, I'd like to have enough concrete to set the base on to prevent flexing,etc... is concrete OK to use for this? Should I make it wetter than normal to allow it to ooze better under the unit and allow it to level out easier?
Any advice is appreciated.

Use a 5-gallon container of joint compound and spread if all around where your shower stall bottom will go. Just keep it away from the drain.

Concrete is not the best for what you want to do because it contains small stones which will get in the way when you set the pan in place.

I want to thank you for your great compliment!!

Not all manufacturers recommend or suggest this method for support but its better being safe and knowing that no movement will happen between tub or shower base at the drain assembly when you start to use it. You also don't need any flexing in the bottom that could destroy the fixture surface or worse!

pkandra said what I have always been saying - use JOINT COMPOUND or MORTAR MIX (no stones - hint.hint) for setting fiberglass, acrylic or steel tubs in place to ensure a solid base - no movement!

Brewbeer hit on the head with the stones! It's the last thing we wanto see cause you would not be able to level things out easily when seting your fictures in place.

I personally would go with 1 - 5 gal general purpose pre-mix and be done with it - no mess and easy!!!

Thanks again! If you need anything, let us know or e-mail me.
