After you take the sink off there might be bolts to the floor. If not the pedastal is probably just caulked to the floor. Just pull on it and it will break loose.

Cabinet style vanities are the most popular style. They are mounted on the floor, along a wall and have a mirror installed above. Here is what a typical cabinet style bathroom vanity looks like -

if its a pop up plug you may have moved or lossened the rods at the rear of the sink,check them out

Standard Vanity height is approx 34.5". A vessel vanity is approx 31" high. If you cannot remove the legs from your existing vanity then it will have to be replaced or cut down to the correct height. The reason a vessel vanity is lower is because your sink will be approx 3 to 6 inches higher than a standard drop in sink. This may be more work than it is worth. Vessel sinks most often will require a solid surface top, either glass, stone or another type of composite material. The standard laminate vanity top has a particle board substrate which will detiorate quickly at the drain location.

They make a replcement over flow kit.

SOUNDS LIKE YOU NEED TO REPLACE A RUBBER WASHER IN THE FAUCET AS IT SOUNDS FAULTY ,

You shouldn't have to disassemble everything in order to get to the trap (elbow joint). Most pedestal sinks are designed so that you can get to the trap from the back (generally after getting down on your hands and knees and crawling around with a flashlight). Most sink stoppers that are worked from the faucet itself have a little bar that extends down the back of the sink behind the drain. It will clip with a little metal piece to a lever that sticks out the back of the drain before the trap. The lever goes through a hole in the drain and pokes into a hole in the bottom of your sink stopper. As you move the lever, you will notice that your stopper goes up and down.

Unclip the rod from the lever and you should be able to unscrew the lever from the back of the drain (don't loose the little gasket that sits inside the screw-cap as it keeps water from leaking out here). At this point, you can pull out the stopper and see what is going on. If cleaning off the stuff attached to your stopper doesn't solve the problem, you can then remove the trap to see if anything is clogging that. Hopefully, by this point, your sink clog has been identified and you just need to reassemble, making sure when you put your stopper lever back in that you actually get it into the appropriate hole in the stopper itself.

If this doesn't solve your problem, it's more serious and you probably want to call a plumber as the issue is either a clog farther along or a problem with the venting of the sink drain.

Fowl smells related to plumbing can have several causes. Here's a few potential issues that you can check. If none of them solve the problem you may need to call a plumber.

1) Look at your pedestal sink drain connection. Is there an an elbow connecting to your drain or a P Trap? A p trap is a pipe shaped like the letter "p" (hence the name) and it prevents sewer gas from rising into the bathroom. **sometimes an apprentice plumber puts in a pedestal without a p trap because they are fairly difficult to install, and ALL fixtures need P traps. If there is no P trap, then you need to put one in. It will be a tight space, but you may be able to do it yourself.

2) Do you have a floor drain? If so, your sink will need a trap primer at the drain. Or you can pour water into the drain from time to time before it evaporates from the trap

3) If the smell is more of a sulfur type smell and it appears from running water in other places in the house, then it could also be due the type of tank you have if you are on well water

My offhand guess is that number 1 is your issue.

Without further info, those are some of my best solutions so far, but if none of these are potential solutions, then make the following tests

1) close the door to the bathroom and leave it for an hour or two. Return to the room. Do you smell sewer smell? Is it in the entire room or more concentrated in a certain area? If you don't have a floor drain and its everywhere, there could be a missing P trap from a fixture, a lose toilet flange, a cracked drain pipe
2) without running water, smell your drain. Does it have a sewer smell? Then the P trap either is not present or you need to clean the drain with a drain cleaner due to a list of reasons
3) run water. does the sewer smell increase or does one suddenly appear. Is the smell more a different odor than sewer. See if it is the water itself. If so, check other places. If they do not have the smell then you may have recently installed your sink and there is some smell related to the new valve. Then you would need to use it some more until it disappears.

Check the top list, though because I really think you're just missing a P trap

Sewer breaks below the slab, an open pipe somewhere, some issue with the water supply, are among some other issues but that depends on the test
