I’ve never done this before. I understand the concept of having the sink flush with the top for the granite, but the kitchen sink is cast iron and weighs a ton. The cabinets are a very cheap grade. Do you put on a plywood subtop or just use the cabinets as is or support it some other way? No matter how you support it, it seems like you’d have to cut a rabbit into whatever your using to set the sink in and make it flush. The sink does come with supporting hardware, but it looks really cheap.
They’ve also got an instant hot water unit. Can that be on the same circuit as the disposal? An electrican will do it, but I’m curious.
