Sink base cabinet sizes and planning checks
| Cabinet / code | Current size | Typical planning use | Verify before ordering |
|---|---|---|---|
| Sink Base Cabinet — SB30 | 30 in. W × 30 in. H | Compact sink-base layouts where the selected sink and plumbing fit the cabinet. | Sink manufacturer's minimum cabinet requirement, plumbing location, countertop cutout and adjacent cabinet clearance. |
| Sink Base Cabinet — SB33 | 33 in. W × 30 in. H | Mid-size sink-base layouts requiring more cabinet width than SB30. | Minimum sink cabinet size, plumbing location, dishwasher position and filler requirements. |
| Sink Base Cabinet — SB36 | 36 in. W × 30 in. H | Wider sink-base layouts when the selected sink requires or benefits from additional cabinet width. | Sink specifications, plumbing, dishwasher clearance, countertop layout and nearby doors or drawers. |
| Sink Base Cabinet — SB42 | 42 in. W × 30 in. H | Wide sink-base layouts where the kitchen plan and selected sink call for a larger cabinet. | Actual sink requirements, plumbing, countertop seams or cutouts and the remaining cabinet-run dimensions. |
Does a 36-inch sink fit a 36-inch sink cabinet?
Not automatically. A sink's nominal outside width is not the same as its required cabinet size. Use the sink manufacturer's stated minimum base-cabinet requirement and confirm bowl, mounting hardware, plumbing and countertop-cutout requirements before selecting SB30, SB33, SB36 or SB42.
Plan the dishwasher and fillers at the same time
When a dishwasher sits beside the sink base, include its required opening and any finished dishwasher panel or filler in the complete cabinet run before ordering. Do not use a filler to compensate for an unverified appliance opening. Check door and drawer movement, wall conditions and exposed cabinet sides as part of the same layout.
Important: cabinet width alone does not confirm sink compatibility. Verify the actual sink, faucet/plumbing route, dishwasher and countertop requirements for the project.
Use the kitchen cabinet measuring guide or send your measurements for review. For cabinet-box choices, see cabinet materials and construction. If the dishwasher terminates an exposed run, review dishwasher panels; for planned wall or appliance clearance, review cabinet fillers and trim.
