basement shower question

1491 Views 5 Replies 4 Participants Last post by  oh'mike
Basement is roughed in for shower. Hole is approx 2 feet by 2 feet. Pipe is ready for shower drain. My question is do I have to concrete over the hole and leave the pipe standing(like the concrete is poured around the toiler drain) or can I just fill the hole with stone, and frame the subfloor panels over it?

I suggest that you repair the concrete slab (put plastic down before you pour the concrete. It will assist in keeping down dampness (if that is a problem) and support the shower base or subfloor and shower base. Test the waste line first.

Its possible that the ground water level could rise and water to flow up through the stone and leading to flooding of the basement.
The opening should be sealed, as is the toilet!

What kind of pan are you installing? Is the drain pipe 2"----A large opening is often left for a tub---but seldom for a shower---

I will be installing a maax shower kit. There drain is a 2" as required for this shower kit.
Fill with gravel----then,as you are installing, top the hole with some masons mortar----

You will want to put some mortar under the pan to properly support it---there is an advantage to having a bit of wiggle to the pipe===it's much easier to set the drain if the pipe can be moved a bit.
