I’ve been doing this for quite a few years and this will be my first corner sink base. I think we’re leaning towards an inset base style and would like to use a full size sink. I can think of several ways to build a corner sink base, but I’m looking for the best way. Would you share your construction methods and especially how you do your stiles for the inset portion?
From contributor J:
I've only done one corner sink on a face frame inset door cabinet and I actually built it a bit different. Instead of making a box which would have been huge (45" out from the corner) for the size we needed, I built the face frame and then assembled the interior on site. I installed the flanking cabinets and the face frame at the same time and then added a bottom panel and counter supports at the back afterward. It worked out well and I didn't have to build a monster sized box to do it. Here's a photo, as it may be easier to see it than explain it fully.
The back's 44 5/8" to the outside, front's 26 15/16" with the miters. Other than that, it's a standard depth base cab. Stiles and rails are 1 11/16" with a 5/16" bead (2" total), and the door (couldn't tell you if it's been fitted yet, so may have been made a smidge bigger) is 19 13/16" x 18 11/16". There's approximately 8 3/4" inside clearance at the back where her pull-outs will be there on the side before the miter comes back.
Making the miters on the frame is important, and the easiest way I've found to transition. It causes a nice even flow between frames and installs essentially the same as the rest of the cabs.
