I think 20 gauge is too thin. It will be noisy, and have a "tinny" quality to it when you set things in it. But to me, the bigger problem is the type of corner sink you've chosen. That style of corner sink has been really criticized on this forum in the past. I think because each bowl is too small to wash anything in, it's un-ergonomic, you cannot have two people at the sink, and you will have major dripping from bowl to bowl. I know you have your heart set on this style, but I just thought I'd warn you, since it's VERY permanent, given it'll be undermounted, and your countertop will have to be cut to fit it. Perhaps you could start a new thread about that style of corner sink and get others' opinions.

I myself have a corner sink I love, but not in the configuration you've chosen. I'll link to a thread where people discuss their corner sinks and have pics too.

We have some very heavy cast iron cookware so we ended up getting a 16 gauge sink. I agree with akchicago about the batwing corner sinks being less than ideal for all the reasons mentioned.

20 gauge is too light weight. Get at least 18 gauge. Have you considered Ticor sinks that so many of us here have used? I believe most of them are 16 gauge.

I agree with the previous post that 20 gauge is too thin.

To the OP - have you LOOKED at the specifications of the sinks you cited??? One of them has bowls only 13" wide. Take a ruler and see how small 13" is. It's useless for a main kitchen sink. The other sink's largest bowl is 15" wide, also a poor choice. I think you must not have seen those dimensions.

As others have said, the batwing sink is a poor design. Corner sinks--but not batwings--are actually very efficient use of space in a kitchen and an excellent design choice. You will be happy with a corner sink in a more standard rectangular shape.

I agree w/AlwaysFixin here too!

With the batwing design, you have to be very careful when moving the faucet...you can't just move it from one sink to another while running...you have to turn it off first, move it, then turn it on again. Additionally, the sink bowls are too small to be very useful...especially as a main sink.

Regarding size...for a prep sink, you shouldn't have a sink smaller than 12" square...and 15" - 18" is better. For a main sink, you really need one much bigger.

We have a corner 15-3/4" square prep sink (Kohler K-3345) and I would not consider anything smaller (it's in a 36" corner sink base).

Our main sink (Ticor S405D) is two bowls - one side is only 10-1/2" wide, but it's used primarily for soaking utensils and filling things...not for washing or rinsing dishes. The larger bowl is 21-1/2" wide...a wonderful size...big enough of our largest cookie sheets & largest frying pan + handle. It's also 9" deep + the 3cm granite depth = 10-1/4" deep. Great all around. This sink fits in a 36" standard sink base.

If you must have a corner sink for your main sink, I would think seriously about a single bowl for maximum size...and I'm not normally a single-bowl proponent!

BTW...our prep sink is 18-gauge & our main sink is 16-gauge...both are fine.

Thanks everyone, that's why these forums are invaluable!!! I looked at some Ticor sinks online, but couldn't find one in a corner design. Now, I'm back to searching for an actual corner sink that's 18 gauge or less. I hadn't even thought about the undermount batwing design being to where I drowned the cabinet everytime I moved the water from one sink to the other!!! If anyone knows of a topmount 18 or less gauge actual corner sink....please send me a link to it, because all I've found so far are 20 gauge. I really wanted the corner sink design instead of just using a standard sink at an angle.

Bjcraddock - can you clarify? You've decided against the batwing design, right? If so, then what do you mean by a "an actual corner sink"? Why are you against using a standard sink in the corner? (see my linked thread in my post above--those corner sinks look good)

I really want the batwing look, but if it's a topmount, I won't have the problem of the water from one sink to the next. I just think they look great! I don't want an undermount one now though. The standard sinks in the pictures do look good and would be fine if I can't find one like I want in the the 18 or less gauge....but you know how you have something pictured in your head and it gets stuck there??? LOL! My husband, god love him, really wants that batwing design,too. It's very rare in this new house planning that he gets to have much say in alot of it, so he would be thrilled if thought he was getting his way!!!

So, you're not concerned with the batwing sink bowls' size? 13" is mighty small! (My sink is 28" or something like that, and I use every inch LOL!)

I'm sure these sinks are on the pricey side as they are custom made, but I'd consider this as an area that I'd be willing to spend more on to actually get a good sized sink and still be able to make use of the corner cabinet. In my kitchen that's an awful lot of wasted space for a sink that's too small.

Consumer Reports again this year found no difference in the performance of 18-22 gauge sinks during their testing. We put a 20 gauge top mount sink in my Mom's new kitchen and it doesn't flex or sound tinny. Many quality manufacturers make 20 gauge top mount sinks. I wouldn't not get the sink you want because it's 20 gauge as it will have no impact on the look or the performance of the sink.
