If flange to flange is 30 inches that's all you should need a half inch of wiggle room is probably for the best tho More on reddit.com

Some manufacturers call them e-granite. As some have said, it's more of a composite, not actual stone. I've had two in my kitchen for 5 years now and they're both holding up fine. The soap/dirt does show a little more on black than stainless, but a scouring pad or magic eraser will have them looking like new pretty easily. More on reddit.com

Yes, I have an anthracite Blanco sink. It’s not black but pretty close. It’s very dark charcoal. If does take a bit more upkeep but it’s very pretty. I put one in my condo where I lived by myself and it was much easier to keep clean than in my new house where I don’t live alone. You need to rinse it down instead of just letting stuff sit in there so consider who is in your household and how tidy they are More on reddit.com

I don’t know brands per se, but I would tell you to pay very close attention to the style of sink that you get. Something that is popular now like I think they are called apron farm sinks, where the sink pokes out from the countertop in the front and overhangs part of the cabinet, may be popular now but might not be all that popular in a few years. Also there are single bowls and multi bowl thanks, sometimes the separators for those multiple bowls go up to the height of the sink bowl, or sometimes they only go up partway. My wife for example liked the idea of having one of those single bowl type of sinks but when she thought long and hard about it she realized that she uses two separate bowls in the sink one for washing and one for rinsing, so while she like the idea she needed them to be separate. We compromised when she saw that there was a company that made a mid rise two bowl sink for the kitchen and that’s what we went with. Something else to consider is the shape. I would suggest that you try to pick with a somewhat typical sink shape, and not something too unique if it’s going to be under mounted, meaning that it’s underneath the countertop, because that would mean a very special sort of cut out, and trying to match that in the future would be a real challenge. Just my 2 cents. Hope it can help in your decision! More on reddit.com
