Hi Tom,

I have a question for you, we are building a shower stall and using the drain and vent from a sink we removed. {Note the bathroom is gutted and the floors are currently bare}

The question is this, currently the drain pipe (PVC) to the new shower drain location is about 2 1/2 to 3 feet. With the tee being placed as low on the drain pipe as possible, and adding the necessary slope, the drain is elevated to more than 10 inches. That's quite a step up into the shower, and more importantly, a nasty step down.

So, the options seem to be these;
1] Jackhammer around the existing (closer) drain pipe, find a way to make sure it accomodates the sink, and make sure the shower floor isn't too high.
2] OR....Cut or jackhammer the nine feet over to the bathtub drain and tie into it somehow.

I would appreciate any opinions you have, as I am really apprehensive about jackhammering the nine feet to the tub, and equally as unknowledgeable about jackhammering around PVC in concrete.

Thanks,
Jules

Good morning Jules,

If you're giving me a choice between door #1 or door #2 I'm gonna hafta go with door #1 and drop the tee down.
However I think I would have laid it out a little different.
But first let me be sure I have it straight. With #1 you plan on keeping the lavatory where it is and adding a 2" drainage tee under the cement to pick up the shower. This would wet vent the shower, right?

Let me offer you door #3, where you will still have to break concrete but it will be hidden after you're through.
Take out the tub and move the trap back to accommodate a 5' walk in acrylic or fiberglass shower enclosure. You have the drainage and the water in place, you're vented and the cement patch will be hidden. You may even install his and hers shower heads since you have the space.

I've offered you a alterative that's both easier and sexy to boot. What more could ya want???
