Kitchen sink sizes
Sizes from the makers' spec sheets. Every sink is different, so check the sheet for yours before you buy the cabinet.
Short answer
The 33 by 22 in sink is the one Kohler and Elkay both make, and it needs a 36 in base cabinet. Bowls run 8 to 10 in deep. The makers want the base about 3 in wider than the sink.
Sink size and base cabinet chart
| Sink | Width | Front to back | Bowl depth | Smallest base |
|---|---|---|---|---|
| Kohler K-31466-1 Prologue (single bowl) | 33 in | 22 in | 9 in | 36 in |
| Kohler K-3821-4 Vault (single bowl) | 33 in | 22 in | 9 in | 36 in |
| Kohler K-5267-3 Verse (double bowl) | 33 in | 22 in | 9 in | 36 in |
| Kraus KHU100-30 (single bowl) | 30 in | 18 in | 10 in | 33 in |
| Kohler K-5409 Strive (single bowl) | 29 in | not listed | 9 in | 30 to 33 in (Kohler says 30 in may need the cabinet modified) |
| Elkay LR2522PD (single bowl) | 25 in | 22 in | 8⅛ in | 30 in |
Smallest base is the narrowest base cabinet the maker says the sink fits, measured outside the box.
What size base cabinet for a 33 inch sink?
A 36 in sink base. Kohler lists 36 in as the minimum for all three of its 33 in sinks above, single and double bowl. A 30 in sink takes a 33 in base, and a 25 in sink fits a 30 in base.
Don't go by the sink width alone. The cabinet sides eat part of the width, so the opening inside is narrower than the size on the box.
Sink base cabinet sizes
Wolf makes sink bases in these widths:
24, 27, 30, 33, 36, 39, 42 in
Farm sinks get their own base with a cut-down front. Wolf's come 30, 33, 36, 39, 42 in wide. A sink base is the standard 24 in deep. The cabinet sizes guide has the rest of the boxes.
Counter space around the sink
The NKBA guidelines ask for 24 in of counter on one side of the main sink and 18 in on the other. Put the dishwasher within 36 in of the sink. For a wheelchair user, ADA puts the sink rim no higher than 34 in.
