Installing a basement shower stall

[audsp98]

I have 2 pipes that were installed when my house was built. One is obviously a toilet pipe and the 2nd is a 2" pipe for a sink and shower hook up. My problem is that the builder did not put a trap in the floor for the 2" pipe and now I have to figure out how to put a trap under a shower stall.

My delimma is I'm trying to get around breaking up concrete to put the trap under the shower. So, what's the minimum distance I need to install a trap under a shower? My plan was to create a floor to set the shower on but I'm not sure how high to make the floor.

Thanks

Normaly there is a stub out for the shower / tub because the plumber did not know where the shower drain and trap had to be located, it will be under the cement.

If you're referring to the 2" pipe that is coming from the floor, there is no trap connected to it that I can tell. I've ran water down into the pipe and it all disappears. Meaning I can't see that the trap, if there was one, is holding the water. If there is another way to test for a trap please let me know. Otherwise I go back to my original question. How much do I need to build my floor up to give room for a trap under the shower without having to break up the concrete?

Strictly a guess, but I say probably 12" or more. That said, that would be a very poor alternative. It would be very "Mickey Mouse" and even for a basement shower, an eyesore. You are making too big of a deal out of breaking out concrete. Yes, it would take some effort, but it's the only right way to do this. I would suggest that before you make any decisions that you call in a professional plumber to evaluate the situtation and advise you on the best way to proceed and an estimate of the cost. It could be you could do part of the work and save some money.

You will need to break up the floor to see whats up. Then call a plumber. OR call a plumber first and see what he says.

Assuming there's no trap in there now, doing one below slab is not a big deal. I was in your boat and these guys guided me thru it. A tool rental ctr will have a good rotary hammer for $50/day. You can drill and chip out the hole with relative ease. Just be gentle around the below-slab portion of the drain, since you'll need to connect yr trap onto it.
