Nicole: If the end pieces I pictured above were missing, you'd be looking at an exposed cabinet style and the top and bottom rail on each end and a hole between the three. The drawer end covers the void and makes your eye continue the line from the doors upward. A flush piece in the void would have to fit perfectly, be finished matched, would not continue the line, and would therefore look stupid. You're not going to find any pictures because no one would ever go through that much work for something that's not going to look good. Here's a full size 33" apron sink properly mounted in a 36" cabinet. The distance from the cabinet end to the sink apron end will be 3" on your job, not the 1 1/2" pictured here which I admit doesn't look too bad. That sink was replaced by this short apron Elkay Quartz Luxe. The bottom of the apron now lines up with the adjacent drawer bottom, and there is virtually no cabinet face exposed which I think looks better. I made the customer find a factory painted color match trim (you provide, you agree color matches) which I installed above and flush with the top of the middle rail to fill the gap. That didn't have to fit nearly as nicely as flush side fillers would have to, because only the person reaching under the sink will ever see it.

Personally, that would waste too much storage for me. Kitchen design is about maximizing with what you have, ie storage for most people. I consider the sink cabinet to be the "junk" cabinet since I can't really use it for normal storage. With the extra space, I would have them make me a set of narrow drawers or a vertical tray cabinet with the extra space if you can still do that. If not, can you make the sink cabinet smaller and the cabinet next to it bigger? Another option is Kohler Stages sink which is rather cool! It is larger than 30 inch. 45 inch won't fit. http://www.google.com/products/catalog?rlz=1T4ADBS_enUS323US323&q=kohler+stages&um=1&ie=UTF-8&cid=4271464191108650335&ei=tbhkTNyuBIaEtgPZxe3qCg&sa=X&oi=product_catalog_result&ct=result&resnum=4&ved=0CEYQ8wIwAw# There are other companies that make sinks with a shallow portion attached to the deep portion. I think Blanco makes one. This give you a purpose for having a large sink cabinet if you like the functionality of these sinks. You can try to find one that fits better in your cabinet. Another option it to have a large one (30inch) plus a small (10inch?) one mounted side by side.... I realy like this option. This way you have a real useful (30 inch) size sink plus the added functionality of double sink! Just a few ideas if you have not thought of them. If you rejected them already, never mind.

We are almost done with the process of installing our cabinets ourselves--due to a change in circumstances this has turned into a DIY project from a professional installation. We have a 42 inch corner sink base--the 42" is measured from one of the cabinet sides adjacent to the door to the opposite cabinet side. If ours was the unit the last picture above the cabinet side just to the right of the door would be 42 inches from the cabinet side that is attached to the kitchen's wall. For our setup, we can go up to 33 inches for an undermount, bigger if we put filler pieces between the sink base and adjacent cabinets or if there are no top drawers in the adjacent cabinets. If you want to go with the 33 inch sink, you need the 42" corner sink base. Hope this helps. We're still trying to pick out our sink--we only have to install the sink base and a couple of relatively easy other cabinets in this week so we can get templated (no pressure). Good luck!
