The best you can do is round off the edge of a floor board and finish it to match. Just hope it matches.

ChatGPT is only partially correct. You can fabricate it out of flooring if, it's unfinished. For pre-finished you have to purchase it from the manufacturer for best match. Some manufacturers do not offer stair parts.

Oh, for the love of Mike! AI doesn't "know" anything. It will respond to your cues and tell you what it "thinks" you want to hear. As a source of actual, factual information it is completely worthless.

That's why I asked the question. And we did purchase stair nose from Mannington with the name and color of our floor and it was as off as it could be. The rep told our dealer flooring and stair nose are made in different plants. A big flooring company should be able to do better, IMHO.

I agree, they really should be able to do better! I'm sorry I don't have any good ideas for you, as this situation is well outside my experience. But if sympathy is any good to you, you have mine, in spades.

I googled and I think the bullnose is vinyl. If correct, you do have an issue with Mannington.

Ours is Bengal Bay in the color Sand. I wish what they had sent was this color. It's way closer to the correct undertone. Thx for looking that up!

If your contractor is not keen on staining then get someone who can do it for you. I personally would try someone who refinishes furniture or makes custom furniture and get them to stain and finish it for you.

Get someone to stain it to match and move on . If it is vinyl not going to happen. I have dealt with Mannington for many years and never had issues but things happen. ChatGBT is not where you go for help ever.

LOL. I'm hearing and seeing more of that rubbish. The dumbing down of the internet.
