I guess I need to ask why left? I still like my drain in the center so not sure what the issue is so bear with me .

I think you have to go to the southern hemisphere to get one.

Go custom and you can have your drain anywhere you please.

Yes, you can get a left hand drain in front, middle or rear position from Julien (Home Refinements). I have used 4 of their sinks in 2 kitchens and been very happy with them. My builder's price through his preferred plumbing showroom was much lower than msrp/list.

My current ones are main sink 30" x 18" x 10" deep (plus an integrated 16" x 18" drainboard) with a right rear drain and island sink 18" x 18" x 10" deep with a center drain.

It's not rear, but this one can drain center left or right. It's 10" deep though. https://www.homedepot.com/p/eModernDecor-Workstation-32-in-Undermount-16-Gauge-Single-Bowl-Stainless-Steel-Kitchen-Sink-with-Integrated-Ledge-15-mm-Tight-Radius-WSR3219/312664338

Ruvati Gravena

Left side drain but not left rear corner drain^^.

Create Good Sinks Offset Left Drain

This one looks like a corner drain^^

A rear corner drain was a must have for me. Love mine.

32" is not a common size -- if you look for 30 or 33, you'll probably have a lot more luck!

I guess I have always had space for the things I put under the sink I have never had a client with that preference either .

my preference for a side drain (doesn't matter to me whether it's left or right) it that I like the faucet and drain offset (faucet centered on drain - makes setting pots or dog bowls on the counter next to the sink easy while they fill) as it gives me a lot of non immediate sink space to put things that I don't need running water on. I can also set a half sized sheet pan in the sink without covering up the drain. It's a slight preference but with the availability of offset drains, no reason not to.

I just installed a Ruvati undermount stainless with a side drain. Mine is on the right. But the plumber asked me if I wanted him to flip it and put it on the left. The only difference that I could detect wass the Ruvati name plate would be on the front of the sink side and not the back. If I did flip it to the right side, I wouldn't be able to see it. Unless you are installing a farm sink, it shouldn't make much of a difference.

That^^ is one option for a left side drain but it won't be a left corner drain. I like the corner drain because it gets the drain lines a few inches deeper into the cabinet.

I had an Elkay left corner drain that I loved but it may not come in the size you want. If I recall it has to do with the slant and sink can’t be too long or it won’t drain properly.
