pedestal basin wall attachment to old plaster walls

hello all,
the wife and i are considering a pedestal sink for our bathroom.
1) the 100 year old walls are plaster and i don't f now what to attach the basin to. are there typical wall studs under the plaster? do i have to dig into the wall to find an place to anchor the basin?
2) the waste drain and supply lines come up from the floor. does this preclude us from a pedestal?
any advice would help. thanks

Pedistal sinks are wall hung items. The pedistal is mostly a decorative thing. In order to install one, you will have to find solid backing in the wall to mount it to. That backing can be the studs, IF they happen to be located exactly where you need them to be. (Chances of that are about the same as your chances of winning a lottery.) What type of lavy do you presently have in the bathroom? If it is wall hung, then you have solid backing in the wall, and locating it should be pretty easy. Question becomes --"is it in the right location?"

Having the water lines coming up from the floor will be no problem. Having the drain line going down through the floor raises a couple of issues.

First, assuming that you want the drain line to be hidden by the pedistal, the drain will then be what locates the sink for you. You may or may not have backing in the wall exactly where it needs to be to hang the lavy from. You may have to locate the new sink slightly to the left or right of the present location in order to mount it to the wall, and you may not be able to keep all of the drain line behind the pedistal.

Second, when you say the drain goes down through the floor, that would tend to indicate that you have an S-trap, not a P-trap. S-traps are no longer allowed by code, for good reasons. They can siphon the trap dry and you will get sewer gases in the bathroom if that happens.

Installing a pedistal sink is certainly a doable project, but it may turn into a bigger undertaking than just taking out the old sink and installing the new.
