I am planning a bathroom remodel with a limited budget. My house has a concrete slab foundation. I would like to either move the toilet entirely to a new location or rotate the toilet 90 degrees. Would this require extensive plumbing renovation?

Rotating 90 degrees is no issue, just do it. Moving to a new spot will require breaking up the floor and splicing in some new drain, maybe a new vent to depending on what you have planned.

Hi there Lily,

This one is pretty straightforward, since you know that the toilet drain is in the floor. If you move the toilet, you have to move the line that the toilet drains into. If it's close to where the toilet was, then you can cut the concrete between the two locations and connect it. If you're closer to another 3-4" DWV(drain/waste/vent) line than you are to the old closet flange, you can tie into the closer line if it is less trouble.

To keep from busting concrete apart, I have used a raised wooden floor in the bathroom allowing you to run the plumbing through the wood floor. It's hard to make this look elegant, but it works, and it saved time & money. I did this in a basement bathroom addition, where the looks were secondary to having a functioning water closet :)

Thanks,
