Our GD is in the larger bowl b/c that's where most of the dirty dishes are stacked & rinsed. We use the smaller side to soak utensils so our large bowl is the one dishes are scraped into. (The other factor was that the bigger bowl is a bigger target for peeling potatoes into!) We did this arrangement purely for the above use, it had nothing to do w/which side the DW or Trash is on. In our case, the Trash is on the left, DW on the right. The large bowl w/disposer is on the left, small bowl on the right. BTW...even though the GD is on the left bowl, our airswitch is on the right side of the sink over the small bowl...no problems w/that location. It worked out best in that location b/c the soap dispenser works best for us on the left and we decided to "balance" the accessories and put the airswitch on the right.

Hey guys - Thanks for the responses. I am new to the DIY/remodel mix that we have going on at our house right now so I appreciate the guidance. Flanges and drain covers is what I was thinking of - I will do some research. The SS in the Blanco anthracite just looks “off” in my opinion but I also don’t want something matching if it’s just going to chip off color in a year. As far as brands of GD’s - I had narrowed it down to the Insinkerator and Waste King. We have a really old GE right now so I was surprised by the size difference of the new ones. Huge! The Insinkerator is just a bit shorter correct? And best to go with SS grinding parts? I’m sad to loose all that under cab space but hoping for something quieter. The old GE can get rid of anything but sounds like the house is coming down when you turn it on. I did already order the air switch button kit (super excited to not reach across the counter anymore) so the countertop folks will have it when they do the template for our granite. Thanks again guys! :)

maybe ask them why? I assume the sink is so deep that you can't get enough space under there to do an appropriate p trap.

I've always used batch feed disposals also. But since the OP is accustomed to continuous feed disposals I think she should stay with that - she's got enough on her plate as it is. Dewayne recommended the 1 hp size, and I agree with that but with a caveat. It's nice to have such a large powerful disposal. However, you - or your plumber - must pay attention to the height of the waste pipe that is in your wall under the sink that takes the waste water out. A large disposal like a 1 hp size may so big that its waste line is lower than the waste line in your wall. That would be bad because then you would not have gravity be able to take the water out. That is often the reason why people opt for a smaller 3/4 hp disposal. Though I would never go smaller than 3/4 hp. Having said all that, Insinkerator sells millions of these 1 hp disposals; many people have waste line low enough in the wall. It's hard to tell from this Insinkerator drawing online - it appears that your waste pipe in the wall needs to be either 11" or 13" lower than the bottom of your sink for this 1 hp disposal to work. Again, speak with your plumber.
