Twenty-seven inches: the width most kitchens skip, and the case for not skipping it
Reviewed September 2026 · Captivating Cabinets
Twenty-seven is the forgotten step on the grid. It sits between 24″, which owns the dishwasher and the corners, and 30″, which owns the range and everything that stacks above it — so most layouts step straight past it. The catalog reflects that: 21 units, four departments, no pantry, no glass, no shelf, no filler. But when a wall measures 27″, this width beats the alternative by a margin most people never work out.
Why layouts step over it
Appliances set the rhythm of a kitchen — ranges at 30″ or 36″, dishwashers at 24″, fridges at 33″ or 36″ — and the cabinets either side inherit those numbers. Twenty-seven belongs to none of them, so it appears only when the wall dictates it.
The catalog is honest about it. No tall cabinet, glass front, floating shelf or decorative part is built at 27″, and the accessory list is two roll-out drawers at $217.75 and $266.50. What you get is the ordinary furniture of a run.
| If you want | At 27″ | Otherwise |
|---|---|---|
| A double-door upper | W2715 – W2742, $234.00 – $516.75 | Available at 24″, 30″, 33″, 36″ and 39″ |
| A corner upper | WDC2730 – WDC2742, $539.50 – $682.50 | The 24″ diagonal and pie-cut range is far wider |
| A sink base | SB27-1, $442.00 | 30″ or 33″ for a full-size bowl |
| A drawer bank | DB27-1, $773.50 | A four-drawer version exists at 15, 18 and 21″ |
| A pantry | Not built | 24″ or 30″ double-door tall |
| A glass front | Not built | 24″ or 30″ GDW fronts |
| A vanity | VSB27-34, VB27-34, VB27FD, VDB27-34, $451.75 – $802.75 | The one department where 27″ is well served |
The arithmetic that changes the argument
The usual instinct with a 27″ opening is to order a 24″ base and close the gap with a 3″ filler. Price that out: B24-1 displays at $471.25 and a base filler at $43.55, so $514.80 all in. The B27-1 displays at $516.75. The two paths are $1.95 apart.
For that $1.95 you get three inches of usable cabinet instead of three inches of trim, and one fewer joint to scribe. There are reasons to prefer the filler — a wall out of square, a door needing clearance from a casing — but cost is not one of them. Whenever a wall measures a real cabinet width, buy the cabinet.
A 27″ sink base, and what fits in it
SB27-1 at $442.00 sits between the 21″ prep-sink box and the 30″ and 33″ mains. Allowing the usual 3″ margin it takes about a 24″ bowl — a large single or a small offset double. Order the cabinet against the sink’s own cutout drawing rather than its nominal size; apron fronts in particular do not follow the naming.
What you lose is the accessory ecosystem: no waste pull-out, no drawer insert, so the space under the bowl stays a plain cupboard unless you fit a roll-out. If the bin has to live under the sink, plan the 30″ or 33″ sink base instead and put the waste unit in a neighbouring 15″ box.
Ten uppers, six standard and four corners
W2715 through W2742 cover the six wall heights from $234.00 to $516.75, and WDC2730 through WDC2742 give a diagonal corner in the four full heights, $539.50 to $682.50. That corner is the reason 27″ appears in more kitchens than people expect — a 27″ diagonal reaches further across a corner than the 24″ version, which matters when the two runs meeting there are both deep.
The vanity list is the strongest part of this width — four codes from $451.75 to $802.75. A 27″ vanity fits bathrooms where 24″ looks mean and 30″ will not clear the door swing, which is a very common problem in older houses.
Common questions
- Should I use a filler or a wider cabinet?
- Where a real cabinet width fits, buy the cabinet. A 24″ base plus a 3″ filler comes to $514.80; the 27″ base is $516.75. Fillers are for absorbing wall tolerance and buying door clearance, not for replacing three inches of storage.
- How much is a 27 inch base cabinet?
- $429.00 for the 12″-deep full-height-door version, $442.00 for the sink base, $442.00 for the standard full-height-door box, $516.75 for the drawer-over-door base and $773.50 for the three-drawer bank.
- What size sink fits a 27 inch sink base?
- About 24″, allowing the customary 3″ of cabinet either side of the bowl. Confirm against the sink manufacturer’s cutout drawing rather than its nominal size, especially for apron-front models.
- Is there a 27 inch pantry cabinet?
- No. Tall cabinets are built at 15, 18, 24, 30, 33 and 36″. For a 27″ opening the practical answer is a 24″ pantry with a filler, since a tall run has more tolerance to hide than a base run does.
- Why are there so few 27 inch cabinets?
- Because appliances set the widths kitchens use — 24″ dishwashers, 30″ and 36″ ranges, 33″ and 36″ fridges — and 27″ matches none of them. It appears when a wall dimension demands it rather than when a plan chooses it.
