The shorter 12″, 15″, 18″ and 24″ walls, typically used above a refrigerator or a range, come mostly 30″–36″ wide. Glass-door versions are listed for many sizes, and the Frameless line adds 21″- and 27″-high glass-door walls.

† The Slim Shaker book prints W3336 and W3342 as 18″ wide; the order code and the door size point to 33″. The catalog page flags both — confirm with our team before ordering.
Refrigerator wall cabinets are deeper: 24″ deep, 30″, 33″ or 36″ wide, and 12″–24″ high (12″, 18″ or 24″ in Frameless). Which wall height suits your kitchen depends on your ceiling and whether you want crown moulding on top — we work that out at the free in-home measure.
Tall pantry and oven cabinets
Tall cabinets come in three heights — 84″, 90″ and 96″ — and are 24″ deep, the same depth as the base cabinets beside them.
| Tall cabinet | Premium | Frameless | Slim Shaker |
|---|---|---|---|
| Utility pantry | 18, 24, 30 | 18, 24, 30 | 18, 24, 30 |
| Oven cabinet | 30, 33 | 30, 33 | 33 |
Bathroom vanity sizes: 34½″ high, 21″ deep
Vanity cabinets are 34½″ high and 21″ deep — 3″ shallower than kitchen bases.
| Vanity cabinet | Premium | Frameless | Slim Shaker |
|---|---|---|---|
| Vanity sink base | 24, 27, 30, 33, 36 | 24, 27, 30, 36 | 24, 27, 30, 33, 36 |
| Vanity drawer base | 12, 15, 18, 21, 24 | 12, 15, 18 | 12, 15, 18, 21, 24, 33, 36 |
| Vanity combo (sink + drawers) | 30, 33, 36, 42, 48 | 30, 36 | 30, 36, 42, 48 |
The widest vanity in the spec books is 48″, but we also supply double-sink bathroom vanities — ask us for sizes.
How to read a cabinet code
For most cabinets, the numbers in the order code give the size: W3036 is a wall cabinet 30″ wide and 36″ high, B24 a 24″ base, SB36 a 36″ sink base and U248424 a utility pantry 24″ wide, 84″ high and 24″ deep. Put your finish’s style code in front — SW-W3036 for Shaker White. Corner cabinets are the exception: in the Premium and Slim Shaker books the BBC36 blind-corner base is listed at 33″ wide, so always read the size from the table, not the code.
Fillers, panels and trim
Each line also lists fillers, end and skin panels, and trim. Fillers close the gap between the last cabinet and a wall so doors and drawers can open; the Premium and Slim Shaker books list them in 42″ and 96″ lengths, along with toe kick and crown moulding in 96″ lengths.
