Wall Support for Pedestal Sink

[Baron]

I'm in process of modeling our 1/2 bath and was planning on installing a pedestal sink.

I know I need to install a wall support between the studs -- but, I have a cold air return that runs right behind the wall where the sink will be installed -- and the duct work is probably pretty close if not flush to the back side of the drywall.

Any ideas?? Thanks.

Put in a vanity...you might be able to do a metal plate then have holes drilled and tapped. For attaching to the studs, you'd want the holes either countersunk so you could use large flathead wood screws, or counterbored so you could use lag bolts. If you got 1/2" thick plate, it would be the same thickness as the drywall, and if the sink was wide enough, you may hide it entirely. On the machine screws holding the sink up, I'd want to use some thread locking compound. This might be overkill, but should work.

Thank Jim for the advice.

I agree -- a vanity would be much simplier-- but I do like the idea of using a metal plate. Aesthetically -- I don't know how it would look.

I could just go ahead and remove a section of drywall and see what's behind the wall -- no big deal -- I guess. I prefer not to.

Another way around this is to install smaller ducting. Not as deep into the stud. I believe they have 1 1/2 deep ducts. You might need to rip down the 2x12 that goes in the wall as a support to thin it out as well. You could end up a little proud. In that event you could simply cover that area with 1/4" drywall. That will buy you another quarter inch.

Good idea too.

I'll let you know how it turns out.

Thanks again guys for the advice.

Question, with the duct work behind the sink I take it that the drain and water supply is coming up through the floor? There is a thread here about installing a pedestal sink that has the drain coming up through the floor and there was a question about with the drain out in the floor that the sink might not work. If you can replace the section of duct work with some flex and use toggle bolts to hold the sink to the wall that might work.

Sorry, wrote this before I seen the pre post.

The water supply comes up through the floor -- the drain is out from the wall.

The duct is off center -- just right of the drain.

In that case the duct is not "behind the sink" it is behind one side of the sink and the anchor on the left side will secure it without worrying about one on the right. Reducing the duct size is the worst idea for solving the problem. If it were really a problem, I would screw the sink to the duct.

Installing a pedistle is usually a pain in
the neck no matter how it goes down...


looking at your pic, I would be willing to bet that
you will need to move the waterlines closer into the
back wall to make room for the stand...

the drain line might be off a tad bit off center too...

that is always fun trying to stand on your head and
install the trap behind the pedistle....


the backing in the wall is probably the
least of your troubles...
which you really dont have to have


for your backing you could just install some plastic
anchors and mount and glue the hanger to the drywall if necessry...

with a pedistle sink ,
the weight is held up by the stand under-neath it....

you could actually just put the hanger on the wall
with plasit drywall anchors,
and glue the pedistle in place with DAP and get by fine

it wont go anywhere unless someone decides to
make love on it...


we run into them all the time that were glued to
the wall with silicone,,,,

of course they dont come off too easy years from now

but that is someone elses problem




Looking at what you got , I too suggest a vanity

Yep -- I've been measuring some different pedestal sinks and it looks like I will have to move the water lines closer to the wall.

I'd like to center the pedestal -- but since the drain is off center -- will this be a problem??

That would be too uncomfortable..

The drain being off center becomes a problem if there is not enough room in the slot of the pedestal to rotate it into position.

Looks like the drain is off center by 1-1/2".

I'll measure the slots of the pedestals -- to see which one would work the best. I guess the wider the better.

HJ,

How would you screw a heavy pedestal sink into a duct? It requires a support stud in the wall which is usually a 2x12 laid on it's face.

The pedestal supports the sink. The screw only holds it against the wall. A piece of sheet metal, the duct, behind the wall with a large sheet metal screw into it will give more than adequate support. A pedestal sink glued to the wallwith silicone, (no screws), will stay there forever anyway.
