Two corner cabinets that cut down on problems in turning corners are the “lazy susan” base and the “blind corner” base.
LAZY SUSAN BASE 36" wide
Always takes up 36" of wall space. Makes good use of corner space but does not allow any adjusting for odd dimensions in a run of base cabinets.
BLIND CORNER BASE 36" to 51"wide
Manufacturers make enough sizes to cover every distance from 36" of wall space to 51". They do this by making the style (panel) between the door and the opening wide enough so the cabinet can be slid forward (called “pulled”) up to 3" and for some models up to 7". Notice on the illustration that the cabinet box is usually made short so it doesn't go back to the wall. Often it is up to 12" away from the back wall. This cuts down on storage space a little. This cabinet gives a lot of flexibility when a run of cabinets has to fit exactly between two fixed points. When designing be sure to put it into the correct run of cabinets, if you have a choice (the run that has the fixed points).
A concern of anybody who plans kitchen cabinet layouts is to get the corners correct. The problem is shown in the adjacent figure. Drawers may be restricted from opening by the next drawer at right angles, or if it clears the drawer, it may clash with the drawer pull or knob.
Many cabinets have no knobs or pulls, so the drawer may clear fine for now. But people may want to “redo” the kitchen later including installing pulls on the drawers. Make sure, then, that you avoid the “corner problem”.
There are several ways to successfully turn the corner. The lazy susan is a popular choice. Cabinet manufacturers make a “base corner” sometimes called a blind corner base, or similar (BC, or BCB).
This includes a 1" filler that “pushes” one cabinet away so drawer hardware will clear. The corner base has a large “style” (panel) that enables the installer to “slide” the cabinet forward or back so that its hardware also clears. It also allows the designer to adjust a “run” of cabinets for uneven dimensions.
You can put a filler piece on one side of two regular base cabinets, to turn the corner, leaving the corner unusable. Of course this is not usually a good idea, but if you are bidding against a competitor who did this, your bid would naturally be higher, all other things being equal.
The corner can also be turned by using a square sink corner, or a diagonal sink corner.
