Squatty Potty 7 or 9 Inch: Which Height Should You Buy?

You’re looking at two white bathroom stools. Same idea. Two inches apart. Somehow this has become a decision that involves your knees, your toilet, and whether the bathroom door will still open.

Here’s the short answer. Choose the height that supports your feet comfortably while you’re seated. The 9-inch Original is marketed for comfort-height toilets and more flexible users, but a taller stool isn’t automatically a better purchase. Think fit first. Neither height comes with a guarantee that it will fix constipation. 24

What are you buying?

The Original is a plastic foot support used while sitting on the toilet. Your feet go on it; your body stays on the seat. The curved shape is intended to tuck around the toilet base. The 7-inch listing describes a one-piece design with a gripped surface and says it should not be used as a step. 1

That last part is worth remembering in a shared bathroom. This is somewhere to rest your feet, not something to climb onto to reach the cupboard.

Should you choose 7 inches or 9 inches?

Squatty Potty positions the 9-inch version for taller, comfort-height toilets and users comfortable with a deeper squat-like position. 2 That’s a starting point, rather than a prescription based on your height.

The toilet matters because it sets where your hips sit. Your legs matter because they set where your knees and feet land. Mobility matters because the position has to be comfortable enough to use. A measurement of your standing height doesn’t settle all three.

Before ordering, sit on your own toilet and look at the available space. Can you bring your feet closer without twisting? Would lifting them make your knees feel cramped? Can you stand up again without a stool blocking your usual footing?

If getting on and off the toilet is already difficult, or bending your hips and knees hurts, discuss the setup with an occupational therapist or clinician who knows your limitations. Don’t force a position because it resembles the diagram on the box.

Our buying judgment: start with the less demanding position if you’re uncertain about flexibility. Consider the higher version when your toilet and your comfort call for more lift. Don’t pay for extra height on the assumption that more must work better.

Will it fit around your toilet?

Measure the toilet base where the stool would sit, the space in front of it, and the door’s swing. A bathroom can have enough room for a stool during use and still have nowhere sensible to leave it afterward.

There’s a reason to confirm the exact model with the seller. At our October 10, 2026 source check, the US 7-inch page displayed conflicting dimensions and weight limits in different sections. Ask for the current specifications rather than choosing whichever number looks convenient. 1

This is especially relevant if you have a broad toilet pedestal, very little floor space, or a strict load requirement. Send the seller the model name and ask for the overall footprint, inside opening, and applicable weight limit in writing.

Don’t assume the model name is a precise measurement of every edge. And don’t use a retailer’s photo of a similar-looking stool as proof that the one in your cart will fit.

Does Squatty Potty help with constipation?

Some people may find foot support makes toilet posture more comfortable. NIDDK includes a footstool among measures that can help people relax during bowel training. It also describes other approaches, including changes to food and fluids, physical activity, medicines, and biofeedback for certain muscle problems. 6

The product-specific research needs a closer look.

A 2019 study followed 52 volunteers over four weeks, first without a posture device and then with one. Participants reported less straining, greater emptying, and shorter bowel movements during the device period. That supports a possible benefit in that group. The fixed sequence and healthy-volunteer population limit what it tells a buyer with ongoing constipation. It doesn’t establish that the branded stool is better than other suitable foot supports. 3

A 2023 randomized study enrolled 41 patients with constipation. They completed balloon-expulsion tests without a stool and with 7-inch and 9-inch stools. The stools changed posture but didn’t improve expulsion time or perceived ease. Balloon testing isn’t the same as a bowel movement at home, but these results don’t support promising relief to everyone with constipation. 4

A 2026 trial in women having posterior vaginal-wall repair found no difference in straining at the first postoperative bowel movement between a device group and usual care. Many participants still liked using the device. Satisfaction and improvement in the measured outcome were different findings. 5

The useful question is whether comfortable foot support helps your own bathroom routine. If symptoms persist, buying a different height shouldn’t take the place of finding out why.

Is the 9-inch stool more effective than the 7-inch?

The 2023 study didn’t find a difference in balloon-expulsion time between the two heights. It did find a greater change in posture as stool height increased. 4

So a deeper position and a better result aren’t interchangeable. Choose height for comfort and fit; the research doesn’t establish one universal winner.

Could a regular footstool do the same job?

NIDDK’s advice refers to a footstool, without requiring a particular brand. 6 The studies above don’t establish that you need the Squatty Potty name to benefit from supported feet.

Our buying judgment is that the Original’s appeal is the bathroom-specific shape. A suitable existing foot support may make another purchase unnecessary. Compare stability, foot space, storage, and comfort before comparing logos.

Avoid improvised supports that wobble, slide, or collapse. Saving a few dollars doesn’t help if you’re bracing your feet on something unreliable.

How much does it cost, and can you return it?

The US Original 7-inch and 9-inch pages each listed $24.99 before shipping and tax when checked on October 10, 2026. The direct-site policy allowed returns within 60 days, with return shipping paid by the customer; purchases elsewhere go back to that seller. Recheck the policy before paying. 12

For a purchase this size, return postage can change the value of trying one height and sending it back. Compare the delivered price and the return cost, especially if you’re unsure about fit. A lower shelf price isn’t necessarily the lower-cost experiment.

What about cleaning and everyday use?

Plastic is the stated material, and the manufacturer describes the Original as easy to clean. 12 That doesn’t tell you which disinfectants are compatible with every version. Follow the care information supplied with your product, or ask the seller before using a harsh cleaner.

Think about the ordinary bathroom details too: who moves it, where it goes during floor cleaning, and whether anyone will trip over it at night. Those aren’t dramatic features. They’re the features you’ll notice every day.

Who should consider buying it?

It belongs on your shortlist if you want a dedicated foot support, the height is comfortable, and its shape solves a real storage problem around your toilet.

Pause if your bathroom is too cramped, the position causes pain, an existing stable foot support already suits you, or you’re expecting the purchase to treat persistent constipation on its own.

You don’t need a perfect squat. You need a usable setup, a manageable price, and a reasonable expectation of what a stool can do.

When to get checked

NIDDK recommends medical review when constipation doesn’t improve with self-care. It advises getting care right away for constipation with symptoms such as rectal bleeding, blood in the stool, constant abdominal pain, inability to pass gas, vomiting, fever, or unexplained weight loss. 7

Those are reasons to get help, rather than keep adjusting the furniture.

The purchase decision

Choose the Original if a bathroom-shaped foot support is worth the cost to you. Confirm the exact specifications, choose the comfortable height, and read the seller’s return terms before ordering.
