Set a level on your countertop and get back to us, please.

I have had 2 silgranite sinks. In the second one (current) I ordered the matching strainer. I had puddles as well. I took that off and just have the stainless strainer that came with disposal and no more puddles. I liked the matching one, but I hated the puddles. The thing I love about the silgranite, I am gone for an hour, come back and it looks brand new and clean, unless my wife and kids leave food everywhere

Absolutely nothing standing in our sink - we have the large single bowl version (undermounted) everything is dead-on level side to side, front to back.

@grammy22 Did you resolve your issue with the water puddling in your Blanco sink?

We just purchased a Blanco silgranite sinks and we spent the money to get the matching strainer. we have puddles just like everyone else, because the basket flange is about a 1/16" higher than the sink. Poor design and they wont take the baskets back one installed. We are going replace the baskets with stainless strainer. It's too bad the design stores don't mention the puddling issue before you spend the money.

I have the same issue. But I also have the matching sink stopper that doesn't hold water. Very frustrating.
