I believe all the plumbing for my basement bathroom is in place. But the tub drain is out of place by about 6". I need to now is there a special type of tub that I need when putting it in a basement because it looks like the w&o would not fit under a regular tub with the concrete there. I have the tools and know how to remave the concrete and move the tub drain to the right location (14 1/2" from the back wall and 1 1/2" from the right wall. Please help me getting flustered.

Hi MM:

A couple options here...

First, remember that the PTRAP will add about a 4" offset to where the drain pipe lines up to the tub waste and overflow assembly... so that with a street 45 degree fitting onto the pipe might just line you up nicely. You may just need to chip out a little concrete.

Another option could be to use an above floor rough in tub waste assembly (see image)... this can offset almost 6 inches if I remember correctly (you can cut shorter). In this case, you may not even need to chip out much if the concrete at all... ;)

Of course, you could also chip up the floor and use a regular tub waste as you suggested may need to be done. but that really shouldn't be necessary here.

Finally, you will probably need to chip out some concrete to accommodate the tub SHOE of the tub waste and overflow, but no need to go too deep.

Post back and let's discuss more... O.K?

So here is the rest of my problem I thought I had it all figured out and already cut a 1' square in the floor so now I can easily move the pipe were ever I need to but when I removed the old P-trap I noticed a black sludge in the trap and in the pipe does this mean that my slope is of and I am going to have a sewage back up issues? And just to make sure I understand exactly what you are saying I should just chip out a groove in the concrete to make room for the wast pipe?

Hi MM:

Some sludge is very common in older cast iron pipe. At this time, I'd suggest taking a hose and hook it up to a hot water source (laundry faucet or the drain at the water heater) and then stick it into the pipe and see if you can wash the pipe down a bit.

You could also rent an electric snake and snake the drain line... use hot water as you snake for a really great job!

For the future, install a full-size cleanout in the tub vent or drain if possible... just in case you need to snake this out again.

In terms of the chip out for the tub shoe, we will typically chop out to 12" off the stud wall... 3 inches to left and right about 1/2 way down will do it... ;)

Thanks Mark you have been a big help. The last thing(if you don't mind) is that its plastic pipe. And that I have to have the tub about 4" from the left wall (for toilet clearance) toilet needs 12 1/2" from stud wall if I remember correctly do you have any suggestions on the best way to fill this space.

Double up the studwall on the left end of the tub. Make sure that you leave at least 12" between studs in the middle to allow for the valve.

Hi MM:

Toilets need 12" from the rough stud for best result...although 12.5 is fine as well, but leaves a bigger space behind the toilet. Toilets also require a minimum of 15" to center from a side wall or tub... 18" works even better.

With that information, do you still need to move the tub?

Finally, what does your toilet pipe measure from the center of the pipe to the front of the stud wall? Let me know...

Right now my toilet pipe sits at exactly 12 1/2" from the stud wall (12" from finished wall with 1/2" sheet rock) the tub has to fit in a 64" space.

[CHayn]

Your toilet will be fine. Just double up the stud wall on either end of the tub( I would personally choose the left side since that is the end your toilet is next to, if I saw the pics correctly). You may need to put 1/2" strips between the two stud walls for a perfect fit. The wall will just have a bump out or offset behind the tub. Very common. OF course, I only mean a short section of wall at the end of the tub. Not the whole length of the room.

Thanks for all the Help that's exactly what I will do. As far as the sludge is concerned should I worry??

MM:

Chayn has given great advice here... ;)

In terms of the sludge, as I posted above... At this time, I'd suggest taking a hose and hook it up to a hot water source (laundry faucet or the drain at the water heater) and then stick it into the pipe and see if you can wash the pipe down a bit.

You could also rent an electric snake and snake the drain line... use hot water as you snake for a really great job!

For the future, install a full-size cleanout in the tub vent or drain if possible... just in case you need to snake this out again.

Hope that takes care of the sludge issue... :)
