Hey everyone. I have a question but I don't have many details so I'm
only looking for a general idea as to what this project is going to be
like. I am considering adding a second bathroom to an investment
property of mine. It's on a slab built in 1964. I'm wondering about the
plumbing part of this project. Is it difficult (expensive) to add a
bathroom on a house with a slab as opposed to a crawl. I'm going to use
existing floor space(utility room). Also, I will hire a plumber, I'm
just wanting some general information about this. Does the slab have to
be disturbed, or can the existing plumbing be "tapped" into? Any help
would be greatly appreciated.

We did something similar in a major remodel two years ago. Added a
master bath and a laundry room at opposite ends of the house.

Needless to say, the plumbing was a bit of a challenge. The bathroom
was close enough to the existing wet wall (all previously existing
plumbing fixtures adjoined this wall) that we just had to tie in to the
existing plumbing. Of course, we needed new drains and vents, and for
that the contractors punched through the slab where necessary and tied
into the old ones.

The laundry room was a different situation, for which we had to add a
new water heater (our house now has two) and new sewer line.
Contractors were able to install these things as the new slab was
poured.

It sounds as if your addition will be similar to our new bathroom. Yes,
the plumber will need to punch through the existing slab to add drains,
vents, and tie into the sewer. They just jackhammer a hole big enough
to put whatever is needed underground, then fill it back up again with
redi-crete. If your water lines are under the slab, they may need to
punch through to get to them, too. But if they are in the attic or
ceiling joist space, the job will be easier and less expensive.

Call a plumber. Get an estimate. That part is free, but scary.

Plumbers around here almost never give free estimates. The repipe guys do
but the repair quotes all cost a nominal fee which is recovered if you
accept the job. Thats not to say; some might in your area.
