Can you make the sink wider?

I used a Ticor "OFFset" single large sink. Nice thing about having a single bowl is that I can fit everything in it. I can fit a large frying pan WITH a handle.

I choose to have an "offset" drain instead of a drain in the center because it allows me to install the Garbage disposer all the way to the left side. This leaves a huge space under the sink for my stuff or for a full pull out on the right side space. If I had a GD in the center - it bisects everything and then the space becomes less usable.

Plus the shape of this particular sink might help with your offset window. take a look at it. In my case - with this model I purchased, I had to mount the faucet on the right side- centered. Just make sure you mount the soap dispenser far enough away from the faucet handle so it doesn't interfere with the faucet.

I would never get a 50/50 double sink - nothing ever fits and it is annoying. Most I would tolerate is a 70/30 sink with the GD on the 30 side.

also - that model comes with and without the grate - I love the grate and think it is worth it - the dishes then never touch any food residue and sauce that is on the bottom of the sink.

Agree with a single bowl sink. Don't think you'll regret that choice. I've seen some folks offset the faucet so that is centered under the window... looks fine that way. My sink won't be centered under the window either.

Yes, offset the faucet so that it's under the window, if you can.

Also, you could buy a sink with an integrated drainboard and put the drainboard to the left.

You may be able to make it look more centered by using a sink with a drain board built in. In our case, the drain board went over the adjoining cabinet...because the drain board is so shallow, it doesn't interfere, but it will allow you to better center the entire sink unit.

Our kitchen sink is centered in sink base, but the entire sink unit is to the right with drain board over next cabinet..

I really like Annie's idea above. It seems to take care of the visual issue. I would center the faucet & the light fixture to the window. I also have an Oliveri sink (though not the one with the drainboard) and I love it. Worth every penny!

Besides the drain board, you can use a different colored countertop (or perhaps even better, a stainless-steel section) starting from the far right of the sink cabinet to just before where the front of the countertop turns 90 degrees to the left. The differently colored section will thus fill the stretch between the two wall cabinets that surround the window, and the matching-size countertop section centered below the window will draw more visual attention than the offset sink. You may want to position the faucet towards the left of the sink, centered in the window, to further disguise the off-center sink. (this will particularly well with a left-side drain, or a D-shaped sink with a rear-center drain).

A differently-colored or styled backsplash behind this countertop section running up the wall could further this effect.

If it's an undermount sink, just center the faucet on the window and it will look fine. If you want it to disappear further choose a sink that blends into your counter; for example, a black silgranit sink would disappear with a dark granite like absolute black or uba tuba. They make a lot of different colored sinks: silgranit, porcelain and cast iron, copper.. etc. I think stainless would be fine too though.

You may also want to install wider trim, as in Annie's photo, to give the illusion of a wider window.
