I am about to purchase a garbage disposal to install myself. Our kitchen sink has a large, deep side, and a small, shallower side. Which side is more appropriate to install the disposal in?
I always install into the smaller bowl. (experienced but non-professional opinion)
If you think about it, the only thing that would prevent access to the disposal is a sink full of water. I'd rather have the larger bowl available to fill up with water and still allow access to the disposal. If the user wants one bowl of water and still use the disposal, it could be frustrating to have to fill the smaller bowl.
I would say that 90% of all sinks with 60/40 splits have the disposal located in the smaller of the two areas. It only makes sense. A lot of people say they want them on the side they wash dishes in. I would be willing to bet that when they have theirs installed on the wash side that eventually they will be rinsing on that side instead of washing. Again, it only makes sense to be able to use the disposal for that forgotten plate or leftovers that have been stored too long while doing dishes in the other sink.
I know my answer is going to raise some eyebrows but here it is... If budget permits, I recommend installing 2 disposals, one on each side of the sink.
PROS: 1) flexibility in which side of the sink you want to wash/rinse/prep food 2) can use 2 different sizes (H/P) of disposals 3) less wear-and-tear on each disposal
CONS: 1) reduces cabinet space underneath 2) more costly to buy/install 2 disposals, compared to 1 disposal
It's worked-out well for me and hope it helps others, too!
Personally, when I'm hand-washing things I use the semi-industrial approach of wash basin to rinse basin to drying rack. That works besg with two full-depth basins, and if the dring rack is on the right (as mine is) the right-hand basin is the rinse and left-handbasin is the wash. The wash basin is the one that will have almost all the food scraps in it, hence if you're going to have a disposal thst's the one which needs it most.
Others use other approaches, but my point is to consider what you're using each basin for and where the disposerable scraps will be.
I'd like it on the shallow side to give me the most range in height for the drain lines going out the disposal, through the trap, and into the wall. The disposal lowers the drain line several inches to go through the disposal itself. Every inch of height can matter when getting the kitchen sink to drain properly.
Depending on your disposal and sink, installing on the deep sink could result in the output of the disposal being below the drain connection in the wall, which would result in water needing to flow uphill, and water doesn't flow very well in that direction.
This has the added benefit of more room under the disposal for storage.
Placed in the big one allows to scrape food from big pots and pans directly to the GD. Small one let's you defrost turkeys, and other meats efficiently. This setup works better if you have a dishwasher on the side of the small one. InSinkErator tutorial video has it this way too
