The term for a drain not in the center of the sink is "offset drain". Usually an offset drain is considered an advantage because (A) it allows more room under the sink for your disposal, cleaning supplies, etc. than a drain that is smack dab in the middle of your base cabinet; and (B) it allows you to set down a roasting pan, dishes, etc. in the sink without covering the drain. This may seem like a minor convenience, but once you've lived with it, you never want a center drain again. I have a large batch feed disposal under my sink (batch feed disposals have larger/wider chambers than continuous feed disposals), and there was no problem with its installation whatsoever. Perhaps the reviewer had a poor drainpipe outlet location from the wall.

Also, no one knows whether the review you saw actually was more of a problem with the height of the drain outlet at the wall than it was the sink's drain location. We have seen on this forum issues where the disposal outlet ends up being lower than the outlet from the wall which is bad. This happens because sinks are deep, plus there is the thickness of the countertop, plus the reviewer may have had a very large disposal. A solution would be the Insinkerator Evolution Compact disposal which has a smaller chamber, while still being a powerful 3/4 hp disposal.

As to the faucet, the issue there is more about the space behind the sink, or the lack thereof, than the sink's drain location. If you have a sink that is deep front to back, and not much room behind it, and you have the kind of faucet that is a one-handle style with the handle on the side, that handle needs a lot of clearance, you will have a problem. I am not sure what other issues could arise that would require the faucet be installed to the side because of the drain location.

Really, I would never get a sink without an offset drain. Others may not find it essential, but I love my sink's offset drain for the reasons I stated above. If you have a plumber installing your sink and your disposal, have him take a look at your plumbing coming out of the wall before you purchase your sink and disposal, and he'll tell you if there will be a problem or not.

akchicago,

Thank you for the great explanation. My DH who does all the plumbing and he said it would work out. I think the issue with the faucet was due the the sink being more square than rectangle and rounded out in the rear leaving less room for the faucet.

Thank you for your help, now I won't be concerned about the offset drain.
