I am in the process of a kitchen remodel and now have come to the plumbing. My original kitchen had a 2-bowl sink and my new kitchen will have a 30" wide sink base with a 27" wide single bowl. There also will be a garbage disposal with the new single bowl.
It is my intention to remove all the in-wall copper pipe and replace it with ABS, and somewhere in my basement I'll switch from ABS back to the original copper with a fernco coupling. In the wall will be a simple tee that will give me a through-wall flange for the outlet of my garbage disposal.
My question is, how high off the floor should I make my drain? I'm thinking the lower the better, that gives me more clearance for my garbage disposal, however it needs to at least be high enough that the trap is still above the floor of the base cabinet. I have no dimensions of the base cabinet, but I'm guessing the floor above the toe-kick is ~4", and I'd need another 8" for the trap to clear, so I was guessing around 12"?
My only research brought me here, however it makes no mention of the garbage disposal and how to plan for that.
