We'd like to move our bathroom wall back about 2 feet, thus moving the toilet and sink. How hard would be?

Question

It's a second floor bath, we'd be backing up into attic space.

Answer 1

Well, you have water lines, waste lines, electric lines (light over the sink, you have the sanitary stack (stuff up through the ceiling to vent the system, will you be encountering heating or cooling vents and ducts? .....What is in back you are moving too?  The great outdoors?  You'll need a foundation for the wall(s) unless you are cantilevering it out.  

Without seeing your set up it's hard to guess what all will have to be changed.

Answer 2

This will cost you far more than the value of adding the extra room.  This is no DIY job, it will require a licensed contractor.

If you insist on making the bathroom larger, expand a different wall where there are no pipes or wiring.

Answer 3

The challenge will be if the drain pipes are in a concrete slab.

Beams in the concrete to be exact. Example: Plumbing may not terminate in a beam. Also how your drain pipes are running below the concrete. Also how old the original plumbing is and what type of material you are tying into with new plumbing.

Best thing is to have a licensed plumber look over the job, to see if any other unforeseen problems exist. I personally have done numerous remodels involving moving plumbing, some are more challenging.  

The rest is usually easier. If it is in any other location such as upper floor or crawlspace then more options are available to complete the install.

Don't forget in some areas, permits will be required by code to do such a job.

Answer 4

you are looking at a LOT of work to move a toilet two feet...

Answer 5

Well, it means moving the wall, fixtures, plumbing and electrical.  Unless you have extra floor tiles from the existing floor that will need to be replaced.  It will be messy, both in the bathroom and in the room adjoining.

It is a lot of work, but assuming you have the necessary skills, or can hire someone with them it can be done fairly easily.

Answer 6

I agree with the above, but your question is very vague, for instance, presumably your bathroom has 4 walls, you have not said which direction you want to extend. Whichever way you go, it will not be easy, even  not possible without some prior basic knowledge of all trades. my advice get in the people with the know-how.....
