Basic Plumbing question

[joekuhns11]

I have a new construction house and i am finishing the basement myself. Currently i am working on the shower drain. I have everything framed in and am going to do an all tile shower.

My question.

They have the P-trap already installed and brought a 2" pvc pipe vertically from the P-trap. They brought the 2" pipe above ground and cut it off and capped it.

So is there a way for me to cut the pvc pipe and attach my drain to it. Kind of like a flush mount drain? Or do i need to break the concrete out and install the drain below ground?

Any input would be greatly appreciated.

I hope you consider adding a dry pack motor bed for your new shower. This is why the pipe is protruding through your cement flooring. It is designed to be cut above grade.

My floor is already concrete and my base of the shower is only 43" x 37". I know i need to add concrete to the base to get the slope, but do i need to do as much as he has shown? If i go to the farthest point from the drain it is 3', so i only have to bring it up 3/4" an inch at it's highest point. Is there any way i can just do a slope so that when it gets to the drain it is pretty close to the same height as the pre-existing concrete floor? i was hoping to just find a drain that would fit into the flush pvc and only stick up an inch or so.

or would it be just easier to break up the concrete slab around the 2" PVC and install the drain below ground level. That way i can use a lot less concrete to do the slope since i could determine the height that sticks above ground?

If you try to taper a dry pack to >zero< thickness next to the drain, you will be destined to have lots of problems. Do you have a curb installed yet?

All i have is the framed in shower stall. I made the door way so the bottom of the doorway is 6-8" off the floor.

Are you planning on using a Kerdi Shower membrane system? What are you using to stop the water from penetrating the walls?

 

[joekuhns11]

To be honest i have no idea on anything. I have no plumbing experience and don't know jack about it. I guess i was hoping somebody would basically tell me what i need to know. All i have right now is a 43"x37" framed shower with a an 8" raised step when i walk in the shower. And the 2" PVC for the drain is sticking up through the concrete. The concrete slab where the PVC sticks up is filled in.

I don't know what steps i need to do next or anything. Any advice would be helpful. I want to do this right.

Here are the questions i have?
1. Why do you put the horizontal 2x4's in between the frame at the base?
2. When i do my floor, do i do the concrete before or after i hang the drywall?

i guess if you could list the steps out in order for me that would be very very helpful.

if you plan on doing this yourself, watch a lot of vidoes and do a lot of research. I have set a few drains but I stop there. The tile guy does the rest.
and YES to start you should open the floor some to set the drain lower. you only need just a little bit of a slope on the floor to lay the water proof membrane. the drain you use will have a flange for the membrane. Common around here to just have the floor hot mopped with roofing tar, then build a slopping mortar base to the drain. the mortar has to be a some what dry mix so it remains porous. this allows water that seeps through tile and grout to drain down to membrane and down into drain. Water is a funny thing. I would have a pro build the pan for you.
