Basement shower drain

We are finishing out basement and have bathroom rough ins. The shower drain rough in is about 1 ft away from where we need it for the shower we purchased. Is there anyway to make it work without breaking up the concrete?

Re: Basement shower drain

Short of building a raised floor -- not really --- it's only a foot -- best to do it properly and bust the concrete to change the drain location. You could always get a shower that fits in that location.

Re: Basement shower drain

you should break the floor. Should be able to do this with a sledge hammer without much trouble. What size shower did you get? Alot of times the bathroom is 60" wide and the shower is roughed in for a 48" and there is supposed to be a bulk head wall at one end. Might be why it is off?

Or ---- go out and rent a small portable jack hammer for around $40 --- cut your trench - an hour you're done --- you won't bust your back and feeling like you're doing time in the big house.

Assuming it's plastic ( PVC or ABS ) that's there --- cut out the existing " P " trap run your new line ( don't forget your slope of 1/4 inch per foot ) --- glue on the new " P " trap ( don't use the screw on coupling type ) along with a riser ( which can be cut later -- better too long than too short ) ----

Pick up some bagged concrete and some concrete bonding agent.

Apply the bonding agent to the edges of the old concrete --- mix up the bag concrete --- fill in the trench and you're done.

It just hit me --- probably the rough in was for a tub configuration and the shower kit the drains are usually in the middle of the pan --- that's likely why the foot difference.

You can get shower bases that are the same layout of a standard tub.

The choice is yours --- bust the floor to fit your shower or have the shower fit the existing plumbing.

Re: Basement shower drain

If you do need to break through the concrete and have a circular saw you can buy a 7-1/4 inch Diamond blade for about $10 at the the big box store (at least that was what I paid when I bought one a couple of years ago). Cut out what you need to. Note: The saw blade will most likely not cut deep enough to go through the entire thickness of the concrete as most floors are 3 to 4 inches thick. I would also make cross cuts. Then Take the sledge hammer to it and it will break up a lot easier than just trying to take a sledge hammer to it.

Make whatever method you use to Wear a Dust Mask, Long Clothing, Goggles or a full face shield and if you are cutting have someone follow along with a shop vac to collect as much dust as possible.


Re: Basement shower drain

The problem with the circular saw method it's very messy with all the dust even with the shop vac. I would recommend if you go that route tent the area off to minimize the dust reaching everywhere else. Oh and don't use your best saw it'll get plugged with concrete dust.
