space needed for faucet behind farmhouse sink?
For our kitchen remodel, I plan to get a stainless steel farmhouse sink (apron front), double-bowl with a 60/40 split. My kitchen is small, and I like that the 36" long sink will fit in a 36" cabinet. It seems an efficient use of space.
There's some variation in sink width (front-to-back) among the brands I'm considering. Lavello is 20" exterior width; Kraus, Miseno, & Ticor are 20.75"; Ariel & Vigo are 22.3".
My two top choices are the Ariel (with almost 18" interior width bowls front-to-back) vs. the Kraus (16"). It would be nice to have the extra 2 inches in bowl width of the Ariel. But I wonder if the larger exterior width of the Ariel sink might be a problem.
Would there be enough room behind this 22.3" exterior width sink for a counter-mounted faucet? We'll likely have standard 24" base cabinets, and probably granite countertops with whatever the typical overhang is (1.5"?). The sink will be under-mounted, with most of the 1" wide back rim of the sink under the countertop. So taking into account a tile backsplash (maybe 1/2"?) I'm guessing there will be 3.5" of countertop behind the sink.
How much room do you need from the edge of granite to the faucet hole, to avoid potentially cracking the granite? I plan to get a single-handle faucet, installed with the handle in front, so the handle won't hit the backsplash. I could pull the sink forward some, but it has square front corners, and I'm not sure I like that look.
I also wonder if that extra 2 inch sink width would make me have to stretch too much to reach the faucet (I'm 5'3"). Having the handle in front should help with that, though.
And would I need a faucet with a longer spout reach? It seems that many faucets I've looked at only have about an 8" spout reach. That doesn't seem far enough for an 18" interior width sink basin, does it? I would think you'd want the spout to reach at least halfway across the sink, is that right?
I'd appreciate any advice you have on this!
