Believe me, there are NO plumbing issues involved. What MAY be an issue is finding a hardware store--or other source--for the parts you need to do a changeover. The best thing you can do for yourself is get down and climb under your present sink, the neighbor's sink, your family member's sinks, and familiarize yourself with the plumbing that's under there !! While you're down there, check for leaks, and use a ruler/tape measure to get an idea of sizes. Bathroom sinks are usually 1 1/4" diameter thinwall pipe; the tub/shower and the kitchen sink are, or should be, 1 1/2". One thing to remember: the 1 1/2" thinwall pipe hooked directly to the bottom of your sink, and tied into the "S" or "P" traps under there, is NOT NOT NOT the same as the 1 1/2" drain piping; HOWEVER--there are adapters to mate the thinwall to the heavier piping. By the way, you ARE gonna go to the store and find out what a "P" or "S" trap is, aincha?? Dont be afraid to ask Q's, and do realize many of the guys you ask are about as ignorant as you are when it comes to plumbing....many--not all of 'em. THEN: when you find somebody who sounds like (s)he can help you do this project, and they put down on paper the parts you need, the best thing you can do is repeat the process--go find somebody else at another store who can do likewise, and then compare the parts recommended, &c. Maybe this soundz like plumbing 101--you're right, it is. Anything else spellz disaster in the making, not to mention the resultant feeling you bin ripped off and jerked around, and that you coulda done a better job yourself.... if only.... you'd taken to heart the suggestion of: kenn 1RmSchlHse millersport oHIo -- there's a time and place for spontaneity....

We got the double vessel cast iron sink. It had this illustration about how it becomse a single vessel sink for cleaning larger items if you just fill up both sides enough. We hate it and it's been 6 years, we wish that we had gotten the single vessel one it would have a lot more versatile. It is NOT easy to clean anything big, it's a huge pain, there's really no benefit to having the two smaller sides at all. Soaking things is impossible. I can't really pinpoint all the reasons why we hate it at this moment, but we both hate it enough so that someday I'll spend the money to get the single vessel one I'm sure.

I would never again do a double sink. You just can't wash anything sizeable in there. Even regular pots and pans are hard to wash. Years ago I had an old double replaced with a single, and it hit me what a stupid idea a double sink is. I can wash pretty much anything in my single farmhouse sink, including the family dog.

@julieste - except a lot of times our "habits" are dictated by the conditions we have, mine certainly were with my old double sink (I think it was a 70/30?). Like @rockypointdog, I also stressed and hemmed and hawed and researched a lot before switching. I'm so glad I went for it - it's been a few years and I still love my sink. Would I go back to my old sink or one with a low-divide like my SIL has? Absolutely not. Is it perfect? No. Did I have to adapt? Yes. But, it turns out this old dog can still learn a few new tricks, lol, and even with adapting, it's so much more functional than before. @BeachBaby60 - best of luck with your decision. What width sink are you considering or able to accommodate?
