We have four farmhouse style sinks in two different houses, and all present the same problem. It doesn't have anything to do with the material as two sinks are concrete, one stainless steel, and one composite stone. With the two kitchen sinks it's very frustrating spraying out the food particles from corner to corner. Food particles go from one side to the other, and it's very difficult to corral them to the drain. The two concrete bathroom sinks don't have enough slope, so when shaving and brushing teeth, the water and material flow to the opposite side of the sink. It's annoying to wash a 3' wide sink every time it's used. And gross if the sink isn't cleaned from side to side after every use. As a compromise, we're installing a farmhouse concrete bathroom sink with two drains and more slope. As I evaluate many things in life, a, farmhouse sink is a solutions looking for problem.

Thank you, all of you. But Annette, to me the crazing is not at all awesome; it looks dirty. However, after some more googling, I have found a way. Just like treating car duco. 60 grit sanding, then 120 grit sanding, then something else and then metal polish. There is a video on utube; I hope I can find it again. I did not bookmark the site. I have tested a small area with the 60 grit and I can see that this is going to work. But I first have to find a palm sander; hopefully that is something that Bunnings stocks. I will post a photo when I am finished. Inez. BTW: why on earth would anyone manufacture a sink that can not stand hot water. But ? How hot is hot?

I think it is because if the tap handle doesn’t overhang the sink then wet hands drip water over the bench behind the sink. I have an undermount sink with same issue due to required setback from sink and we are learning to shake hands before turning off tap. Pro for wall mount no gunk around base of tap Negative according to my husband who refused to have wall mounted is the tap connections are in wall so if you get any leaks it’s hard to fix. But this goes same for shower I guess. We did have a faulty basin tap that leaked inside the handle area and down into cabinet so had to get replaced so I didn’t-push for wall mounted again.

Yes I notice the same with those angular, trough-like bathroom basins. You have to put lots of water in before you can dip in a face washer or anything. Plus those squared off basins/sinks tend to splash water more easily. Give me a rounded-off basin/sink anytime. Flush-mount preferably!
