Underground plumbing on basement floor is not according to layout


Hello Everyone,

My house is one year old and is located in Ontario, Canada.

The basement rough-in plumbing was finished when the house was built. I am now starting to finish the basement and I found out that the plumbing in the bathroom is off by about 12". I have been able to solve most of the issues by changing the layout but the area where the shower needs to be, has the plumbing way off and I cannot move the shower to make it fit (please see attached picture)

I am not too keen on breaking the concrete floor to relocate, so I though that I could build a 4 " concrete or wooden riser, that would be about the size of the shower (32" x 60"), that will basically hid the rerouting of the plumbing that I will do above the concrete floor

Any advise?

I have not figured out if it would be even possible to proprly drain and vent that shower with your 4" riser.


BUT: I think you would be asking for a difficult mess trying to do that. First you'd be getting a very strange functionally difficult shower,,, probable all sorts of modifications around the shower.... just a boat load of headaches.

Busting up that concrete is not that difficult and probably your easiest approch in my opinion.

Re: Underground plumbing on basement floor is not according to layout


we would need triangulated measurements of all drain stubs
including toilet flange to better determine your layout...
distances off walls & also measurements between pipes

Peace

Thank you for your reply. Whether it is 4" or 6" wouldn't be an issue as I would do the height required to have proper drainage.
If I break the concrete to fix the plumbing, what are the chances that I can have issues with underground water leaking into the basement (between the old and new concrete)?

Get over it. Then you can be sure you'll get the venting & traps right
as well as placing the shower drain *exactly* where you want it.

Also... allow more thickness on the exterior wall for the 2" XRP behind the framing.

What's the chance you have sub surface water issues....???

Yes a cold joint in your basement will likely have a greater permeability than a good slab..... but slabs crack all the time, with no water problem, unless you have an underlying subsurface water issue with your foundation.

Usually they miss by 8, he added 4" for the wall and then screwed up.
I would break into the concrete and do it right. The tub drain may have foam just under a bit of concrete around it. If you find water down there, that's a warrantee issue.
