Your cabinet for your sink should have been made for a farm sink so not sure what you are asking

I am buying stock cabinets and using a 33" refrigerator cabinet as the base.

Not gonna work unless you have a stellar carpenter involved. Needs a lot of jobsite custom labor. You can't design something that can't be accomplished in the real world with the real world skills of the person actually doing the job. If you have someone involved with enough kills to essentially remake a refrigerator cabinet into a sink base, then he has enough skills to just make all of the cabinets.

We did the exact same thing, used a fridge cabinet and then used a piece of cabinet filler (the pc that does between cabinet and wall) to fill it in. I think it looks just fine. Can you see this ok??

Amber, that looks perfect! Really nice.... It's really easy to do... my only concern was the panel around the sink. Is that filler one solid piece or 3 separate pieces? I was thinking of using a piece of maple and painting it or using a large panel from the company, cutting it down and scribing it.

The only difference between yours and mine is that yours is flush with the cabinet frame. I'd like my filler/panel flush with the doors.

We are farming it out to a carpenter.. The plan is to build a base the same height as the toe kick.. then place the cabinet.. then build up the cabinet so the sink can sit flush with the top of the other cabinets and install the panel in front.

I feel like we may have done the same thing. I will post some pics when I get home this evening if so, if you'd like.

Please.. thanks!
