The 30 vs 24 inch vanity choice looks small on paper. But those 6 inches change your counter, your storage and your elbow room. So this page compares 24, 30 and 36 inches side by side, using only data we can confirm. For the wider picture, start with our 30 inch bathroom vanity guide, then use this page to settle the size.
The Three Sizes at a Glance
Still, these three sizes suit very different rooms and habits. A 24 inch vanity is the small-room pick, and it leaves more floor free. Next, a 30 inch vanity adds counter and cabinet room without eating the wall. Then, a 36 inch vanity adds more of both, but it needs a longer wall to work.
Also, depth changes how far the cabinet sticks into the room, so check both numbers before you fall for a photo. Our 30 inch vanity dimensions and clearance guide shows you how to measure each one.
Width and Depth: The Only Numbers We Compare
The table below uses width for all three sizes. However, depth uses only the models we can confirm. So read the depth rows as examples, not as a rule for every vanity.
| Point | 24 inch | 30 inch | 36 inch |
|---|---|---|---|
| Width | 24 in | 30 in | 36 in |
| Confirmed depth examples | Beaufort 24in model: 19 in deep; Gabi 24in model: 22 in deep | Doveton: 19 in deep; Huckleberry: 19 in deep | Not confirmed in our data – check the product page |
| Full confirmed size examples | Beaufort 24in model: 24 x 19 x 34.5 in; Gabi 24in model: 24 x 22 x 34.5 in | Doveton: 30 x 19 x 34 in; Huckleberry: 30 x 19 x 34.5 in | Check the product page |
That depth gap matters more than you may think. The Gabi 24in model is 22 in deep, but the Doveton at 30 inches is only 19 in deep, so a wider vanity can still stick out less. Also, depth data for 36 inch models is not confirmed in our data, so open the product page and note the full size there.
Our 30 inch bathroom vanities collection lists 10 designs that offer a 30 inch size.
Wall Space and Door Swing
Wall space is the clear run of wall where the vanity will sit. First, measure that run from corner to door trim. Next, take off space for anything that sits on that wall already. If the number left is tight for 30 inches, then 24 inches may be the safe pick.
Door swing is the arc your bathroom door or cabinet doors sweep through. A wider cabinet can block a door that opens in. Also, deep drawers need clear floor in front of them. So tape the vanity size on the floor, then open every door and drawer path in the room.
Also think about style here. The DeerValley and Abruzzo are floating designs at 30 inches, but the Doveton, Huckleberry, Beaufort, Gabi and Korra are freestanding. That said, mount type does not change width. It only changes how the room feels and how you clean under it.
Toilet Clearance Next to the Vanity
Toilet clearance is the space you leave around the toilet so you can sit and stand with ease. A wider vanity eats into that space from the side. So measure from the toilet centre line to the vanity edge before you size up. Then check your local code or a fitter if the gap feels tight, because rules can vary by place.
If the toilet sits close, a 24 inch vanity often keeps things calm. But if you have clear space on both sides, a 30 or 36 inch vanity can still work. Still, width is the number that most often squeezes the toilet gap.
For tight rooms, our 30 inch vanity guide for a small bathroom goes deeper on when 30 inches fits and when it does not.
Storage and Counter Space, Size by Size
Storage grows with width, but layout matters just as much. The Doveton at 30 inches has 2 cabinet doors plus a tilt-down drawer. Next, the Huckleberry at 30 inches has a cabinet plus a hidden storage drawer. Then, the Beaufort 24in model packs 1 drawer plus a cabinet with a shelf into a smaller frame. So a smart layout can beat a plain wide box.
Counter space grows in a straight line with width. At 24 inches, the basin takes most of the top, so you get small edges for soap and a brush. Next, at 30 inches, you gain a real strip on one or both sides. Then, at 36 inches, you gain more again, but only if the wall and toilet gaps still work.
I'd pick 30 inches for a guest bath, because it adds clear counter space over 24 inches without asking for the long wall a 36 inch vanity needs.
Pick 24 Inches If
Pick 24 inches if your wall run is short or the toilet sits close. Also pick it if the door swing is tight, or for a powder room where guests only wash hands. Still, check depth, because the Gabi 24in model is 22 in deep and needs floor room.
Pick 30 Inches If
Pick 30 inches if you want one sink plus useful counter space, or daily storage for towels and bottles. The Doveton and Huckleberry show what the size can hold, and both are 19 in deep. So this size often fits where a deep 24 inch model feels bulky.
Pick 36 Inches If
Pick 36 inches if your wall is long and the toilet gap stays clear, or if two people share the counter at different times. But confirm the depth on the product page first, because our data does not confirm 36 inch depths. Then tape the size on the floor before you order.
A Quick Way to Test the Size at Home
First, tape the width and depth of each size on your floor and wall. Next, stand at the tape as if you were washing your hands, then open the bathroom door and any drawers in your plan. Also, sit on the toilet and check your elbow room on the vanity side.
If 24 inches feels fine in that test, do not size up for no reason. But if your arms feel pinned at 24, then try the 30 inch tape. Still, if 36 inches blocks a door or squeezes the toilet, drop back down.
When None of These Sizes Is Right for You
Here is the honest limit. If two people must use one sink zone at the same time each morning, even 36 inches will feel tight, because these sizes centre on one basin. Also, if your wall run is very short or the door opens onto the vanity spot, even 24 inches may not fit safely, and a new layout may be the right call instead.

FAQ
Q: Is a 30 inch vanity much bigger than a 24 inch vanity?
A: It is 6 in wider, and that gap shows up as counter space and cabinet room. But depth can flip the feel, because the Gabi 24in model is 22 in deep while the Doveton at 30 inches is 19 in deep. So compare full sizes, not just width, then tape both sizes on your floor.
Q: When should you pick 24 inches over 30 inches?
A: Pick 24 inches when your wall run is short, the toilet sits close, or the door swing is tight. It also suits a powder room used mainly for hand washing. However, check depth too, because some 24 inch models are deeper than some 30 inch ones. If the tape test feels cramped at 30 inches, then 24 is safer.
Q: What do you gain by going up to 36 inches?
A: You gain more counter space and more cabinet width for storage, which helps if you keep many bottles or towels at the sink. But you need a longer wall, and the toilet gap and door swing must stay clear. Also, depth for 36 inch models is not confirmed in our data, so check the product page first.
Q: Can a 30 inch vanity fit in a small bathroom?
A: Often, yes, if the wall run, door swing and toilet clearance all check out. The Doveton and Huckleberry are both 30 in wide and 19 in deep, so they do not stick far into the room. Still, a tight door can change that. So measure first, tape the size on the floor, and then decide.
Q: Why does the table list only some depths?
A: Because we only print numbers we can confirm. For 24 inches, the confirmed depths are 19 in for the Beaufort 24in model and 22 in for the Gabi 24in model. For 30 inches, both the Doveton and Huckleberry are 19 in deep. But 36 inch depth is not confirmed, so the table says check the product page there.
