A 24 in cabinet and a 30 in cabinet look close in a photo, but they feel very different in a small room. The 6 in gap changes the wall you need, the counter you get and the floor you keep. For the size story behind this page, read the 24 inch bathroom vanity guide. Cells that say check the product page are not confirmed yet.
The short answer
Pick 24 in if your wall is short, your walkway is tight, or one person uses the sink at a time. Pick 30 in if you have the wall space and you want more counter and storage. So measure width and depth together before you choose.
Side-by-side sizes from confirmed data
The table below uses only width, depth and height data from the confirmed tables. Where a number is not confirmed, the cell says check the product page. Do not fill those cells from another model.
| Product | Width | Depth | Height |
|---|---|---|---|
| Korra 24 | 24 in | 19 in | check the product page |
| Huckleberry 24 | 24 in | 19 in | 37 3/4 in |
| Beaufort 24 | 24 in | 19 in | 37 15/16 in |
| 22 in deep model | 24 in | 22 in | check the product page |
| Doveton 30 | 30 in | 19 in | 34 in |
| Huckleberry 30 | 30 in | 19 in | 34.5 in |
| Other 30 in designs | 30 in | check the product page | check the product page |
Notice one point at once: Doveton 30 and Huckleberry 30 both measure 19 in deep, just like three of the 24 in models. So the jump from 24 in to 30 in is a width jump first, not always a depth jump. But the 22 in deep model breaks that pattern, because it is 24 in wide and 22 in deep. Because of that, compare the exact model, not just the size group.
You can see the 24 in models on the 24 inch bathroom vanity collection page. From there, open each product page and confirm the height, top and sink details before you order.
Wall space: what 6 in more really means
Wall space is the flat wall length the cabinet takes up. A 24 in cabinet needs 24 in of wall, while a 30 in cabinet needs 30 in. That 6 in gap may sound small, but it can decide if a toilet, a door frame or a side wall still fits. Also, measure from corner to corner, not from the old cabinet edge, because old cabinets can hide uneven walls.
If the wall is too short, no other feature can fix it, so mark 24 in and 30 in on the wall with tape and stand in the room to feel the change.

Door swing and toilet clearance
Door swing is the arc a door makes when it opens, and it can hit a cabinet front or a drawer. A 30 in cabinet reaches 6 in further along the wall than a 24 in cabinet, so it has a higher chance of meeting the door arc. But depth matters here too, because a 22 in deep model sticks further into the room than a 19 in deep model. So check both the width along the wall and the depth into the room.
Toilet clearance is the clear space beside and in front of the toilet. If a wider cabinet moves closer to the toilet, that clearance can shrink. That said, the exact minimums come from your local building code, so check those rules before you order.
Storage and counter space
Storage is the room inside the cabinet for bottles, towels and cleaning items. A 30 in cabinet gives you a wider box than a 24 in cabinet, so it usually holds more. Counter space is the flat top area beside the basin, and a 30 in top gives you more of it too.
A 24 in cabinet still gives you real storage for one person, but large spare packs may need another spot. A 30 in cabinet gives you more room for those extras, and more elbow room at the basin. Still, if the room is tight, that extra storage can cost you walkway space.

Depth inside the 24 in group: 19 in vs 22 in
Depth in the 24 in group is 19 in for three products and 22 in for the 22 in deep model. That 3 in gap changes the floor in front of the cabinet. A 19 in deep model leaves more walkway, while a 22 in deep model gives a deeper top and a deeper basin area. Next, think about the door swing again, because a deeper front edge meets the door arc sooner.
That said, the 22 in deep model is still 24 in wide, so it does not give you a 30 in counter. Its extra depth helps at the basin, but it does not add wall width, so pick the width for counter space and the depth for walkway space.
For a small powder room, I'd pick the 24 in size in a 19 in depth before a 30 in size, because it keeps the walkway clear.
Pick 24 if
Pick 24 if your wall measures short and a 30 in cabinet would crowd the toilet or the door frame. Go with 24 if one person uses the sink at a time and you want to keep the floor clear. A 24 in size also suits a powder room or a guest bath with a tight walkway. Also, pick 24 in a 19 in depth if the floor in front of the cabinet is already tight. Pick the 22 in deep model only if the walkway still feels clear after you mark its front edge on the floor.
Pick 30 if
Pick 30 if your wall has room for 30 in plus safe gaps on each side. Go with 30 if you want more counter space beside the basin for daily items. A 30 in size also gives you more storage inside the cabinet, if you can spare the floor space. However, pick 30 only after you check the door swing and the toilet clearance, because a wider cabinet can still fail on those two tests.
Honest limitation
Neither size fixes a room with a bad layout. A 24 in cabinet can feel small on a long wall, and a 30 in cabinet can feel tight in a narrow room. Also, a wider cabinet does not add a second basin, so two people still cannot wash side by side. So pick the size that fits the room you have, not the room you wish you had.
When not to buy
Do not buy a 24 in vanity if your wall is long, you want a wide counter, and clearances still pass with 30 in. In that case, the extra 6 in of width will serve you better each day. Do not buy a 30 in vanity if it crowds the toilet, blocks the door swing, or leaves no safe walkway. Do not buy the 22 in deep model if the floor in front is already tight, because its depth will shrink the walkway more. And do not buy any model until the product page confirms its height, top and sink details, because the table above leaves several cells open for a reason.

FAQ
Is a 30 in vanity always deeper than a 24 in vanity?
No, and the table shows why. Doveton 30 and Huckleberry 30 both measure 19 in deep, just like three of the 24 in models. The 22 in deep model is 24 in wide but 22 in deep, so it is deeper than those 30 in models. So compare the exact model depth, not just the width label, before you choose.
How much wall space does each size need?
A 24 in cabinet needs 24 in of wall, while a 30 in cabinet needs 30 in. That 6 in gap can decide if the toilet, door frame or side wall still fits with safe gaps. So measure the full wall from corner to corner, mark both widths with tape, and check the door swing and toilet clearance before you order.
Which size gives you more storage and counter space?
A 30 in cabinet gives you a wider box and a wider top than a 24 in cabinet, so it usually holds more and leaves more flat top beside the basin. But the gain varies by model, because the basin size and top layout change the flat area left. Also, a 24 in cabinet still holds daily items well for one person.
Should you pick the 22 in deep model instead of a 30 in model?
Pick the 22 in deep model only if you want a deeper basin area but you must keep a 24 in width. It does not give you a 30 in counter, because its width stays at 24 in. Also, its extra depth shrinks the walkway, so mark its front edge on the floor first. Pick 30 in if you need more width.
What should you check before you order either size?
Check the wall length, the door swing, the toilet clearance and the floor in front of the cabinet. Then check the product page for height, top and sink details, because several cells in the table are not confirmed yet. Also, check your local building code for clearance minimums, since those rules decide the final fit.
