You'll require the flange and the stopper. This from HD. Price dependant on the finish selected.

Don’t get a black sink drain flange. They scratch in no time. Nobody will care in any way whatsoever whether your sink drain flange and faucet are the same finish. I also think a black drain flange in a white sink will not look good.

I have a disposal, and in my sink, the disposal becomes the sink drain flange.

Disposals don't typically come with a sink flange

Get yourself an optional drain basket for the opening

Can I use the one on my gold standard sink that was on the garbage disposal side?

Old^^^ not gold

Of course they come with the sink flange. All disposals come with the sink flange. They couldn’t be installed otherwise. Have you never actually opened a box and held one in your hands? installed one? It’s just in stainless, which is fine. The best choice actually.

Ok cool..so I can just use my old one.

Don’t use old parts. You can use the NEW one that comes on your new disposal. Never buy a cheap Badger garbage disposal either. Always go for the Evolution series that won’t rust out and flood your sink cabinet.

We have an insinkerator that we literally just installed so it’s really not old. We are just switching out the sink👍

I hate disposals and especially with only one sink.

Becka M:

I strongly suggest you undermount that sink with a pair of Sink Straps.
