I have an undermount stainless steel sink, 28" x 16" and 8" deep, similar to the one below, but with the drain in the middle. I previously had a double sink, but when I renovated my kitchen, I opted for this size and love it because I have no problem washing large items like my roasting or broiling pan or cookie sheets.
I have a stainless steel double sink with two faucets and a sprayer in my kitchen.
Had the faucets replaced twice, the sink is still in good condition.
I would not replace the sink unless it was damaged, I love the sprayer.
Do not really have a problem washing large items, I have got that down to a science.
My little apartment has a standard single bowl drop in stainless steel sink that is adequate but I would really enjoy a similar builders grade two bowl version.
