how easy is it to replace sink in my vanity?

Question

i have an ugly like plastic sink and i want to replace, maybe with a porcelain one. What are my steps?

the plumbing is fine this is just decorating. i have cut off valves in the bath, so i shouldn't have a prob with flooding.

it's the drop-in sink, so maybe i can take it out and replace huh?

Answer 1

To give you an idea of what you may be up against. You may have angle stops that you can turn off and then again you may not. When your angle stops have not been used in a long time these can freeze up in the on position. So be prepared in replacing those as well. A drop in sink is one of the easiest to replace. Only make sure you are realigned with your plumbing below. Also you may not be able to get the exact depth sink as you have now. If you are not real sure about this replacement my advice would be to call a lic. plumber.

If you have a plastic sink, then it sounds like you have one of those one-piece vanity top/sink combos (the entire top and sink are made from one solid piece of molded plastic). And, you can't just replace the sink portion with a separate sink. Well, I guess you could by cutting a new sink hole with a Dremel tool and installing a new sink. But, if the top is ugly, you probably want to get rid of the whole thing.

In this case, you will have to replace the entire vanity top, leaving a hole in it for another sink to be installed. If you want tile, you have to install a 3/4-inch wood top, cut out the hole for the sink, tile the remaining vanity top (and backsplash and bullnose edge), then set the new sink - including caulking around the rim - and hook up the plumbing.

If you want to use something more like a Formica counter top, you have to cut the top to the required specifications, cut out the sink hole, and install it onto the vanity. Then install the sink as described above.

Of course, you can always go to a home improvement store with your current vanity top dimensions and see if they have a nicer one-piece top than the one you have. In that case, you just have to remove the existing fixtures from the vanity top, remove the old top (usually glued in place), install the new top, and reinstall the plumbing fixtures. You might also want to caulk around any place where the vanity top contacts a wall. If the top is in an alcove (wall on one or both sides), you can also trim up the counter top a bit with a Skil saw to make it fit perfectly.

First, I would take a picture of it for reference. Measure you vanity and sink size. Take that picture along with the dimensions with you to any home improvement store like Lowe's or Home Depot - usually the kitchen design dept. can help with this one - or even an associate in the plumbing dept. can help... show them the picture of what you are replacing and tell them what you are looking for - they can show you what will work (for free) - they can give you instructions on changing out the fixtures too - but for plumbing... I would have an expert install before you have a potential flood on your hands. Good Luck!

Answer 4

This is not an easy job as some might tell you. Replace sink, and some or all plumbing under sink. Replace faucet, hook up water lines, seal around sink and many trips to hardware store for stuff you don't have. Please call a pro.

Answer 5

Yes, it can be done, fairly easy. This is not a job that is not real easy if you don't have a plumbing or installation background. If you are not a do-it-yourself person than have a pro install. The money you spend by having a pro install will be less than fixing your mistake and installing the vanity. Good Luck!

Answer 6

2 screws at the bottom most time, make sure you turn off both water first then loosen the water lines---replace. do the opposite to put back both water hoses and the sink

Answer 7

take a picture of your existing sink as well as the plumbing underneath and take it to a Lowe's or HD store and let them direct you.
