Big Blunder, any suggestions?

Can you see the underside of the sink to see if it looks damaged? If it looks melted from the bottom and is sagging then I would be worried that it might start leaking.

If the appearance bothers you or DW, replace it. Stainless steel is the only way to go. The extra cost is well worth it in the long run.

So far the only blunder I envision is blaming your wife for putting the hot pan in the sink. Obviously, if you were being more help the situation would never have happened. My suggestion is to make it clear that the poor quality sink provided by the manufacturer is the primary issue. Replace the sink with one of "better quality" and make it clear that you are sorry for not being on hand to catch the situation before it occurred. Perhaps even show her the note you will be posting complaining of the quality of sink in the rig.

And it will always remind her to not put a hot pan or lid in the sink. Of course if you replace it,,you might get lots of hugs and thank yous, which might be better.

If there are no leaks and the water still works then leave it till you get sick of looking at it.

I go with new sink. Besides the appearance issue, you will never be able to thoroughly clean the damaged area.

It still holds water fine, is this something that is a have to when it comes to replacing or as long as it holds water am I alright?

I would guess that you will need to replace the sink.It's not usually a major job.
If she can live with the damaged sink,and there is plenty of material left,there probably is not a great rush to repair/replace it.

However,the sooner you can make it pretty again,the more points you will gain!

This might be a good time to go for a bigger sink if you got room. I made mine alot bigger in my off-road popup without too much effort...

Real easy to install...

Just put a new sink in. They're cheap and easy to replace.
