We rarely question how we sit on the toilet. It’s one of those everyday habits that feels too ordinary to analyse. Yet, for millions of Australians struggling with constipation, haemorrhoids, or pelvic floor strain, this small daily posture could be part of the problem — or the solution.
That’s where toilet stools come in. You’ve likely seen them: simple platforms placed under your feet to mimic a natural squatting position while you sit. They’re not just another bathroom gimmick. They’re a clinically supported way to align your body for easier, more complete bowel movements.
But here’s where most people get it wrong — the height. The effectiveness of a Squatty Potty Australia toilet stool depends entirely on how well it fits your body and your toilet. Too high, and you’ll feel pressure in your knees and hips. Too low, and you’ll lose the natural alignment that makes this tool so effective.
This guide will walk you through the anatomy, the science, and the practical art of choosing the right height — so you can turn a routine bathroom visit into a healthier, more comfortable experience.
The Science of Sitting: Why height matters
To understand stool height, we need to look at what happens inside your body when you sit on a toilet.
In a typical sitting position, your hips are at a 90-degree angle to your torso. This creates a kink in the rectum, formed by a muscle called the puborectalis. Its job is to keep things “closed off” when you’re not ready to go. Unfortunately, that same angle makes elimination harder when you are ready.
When your knees are raised above your hips, that muscle relaxes. The rectum straightens, allowing stool to pass more freely and completely.
This isn’t a wellness fad — it’s backed by research.
A clinical trial published in the Journal of Clinical Gastroenterology found that participants using a toilet stool reported less straining, faster elimination, and greater satisfaction.
Another study measured the biomechanical angles and confirmed that a knee elevation of around 30° significantly reduced rectal strain and improved bowel clearance.
So, the “magic” isn’t in the stool itself — it’s in the height that allows your body to naturally do what it’s designed to do.
Understanding Toilet Heights in Australia
Toilets aren’t one-size-fits-all either. In Australian homes, standard toilet seats usually sit between 355 mm and 405 mm from the floor. “Comfort height” models, designed for accessibility, are taller — around 430 mm to 480 mm. That variation changes everything. A toilet stool that feels perfect with one toilet might feel awkward or unstable with another.
The rule of thumb?
The higher the toilet seat, the lower your stool should be.
How to Measure for Your Perfect Fit
Choosing the right toilet stool height starts with a simple, three-step check.
Step 1: Measure your toilet height
Sit naturally and measure from the floor to the top of your toilet seat. Write it down.
Step 2: Assess your comfort range
Sit on the toilet, plant your feet on a stack of books or similar support, and adjust until your knees feel comfortably above your hips. Measure the height of the stack — that’s your target stool height.
Step 3: Consider your flexibility and balance
If you have knee or hip stiffness, a slightly lower stool will make mounting and dismounting easier. Flexibility improves your range of options, but comfort should always come first.
Real-World Examples: What Works for Whom
The everyday adult (Standard toilet)
For most people, a 7–9-inch stool provides the perfect balance between squat and stability. Your knees rise naturally, your spine leans slightly forward, and you’ll feel that subtle release in your pelvic muscles.
The taller user (Comfort toilet)
If you’re over 6 feet or have a higher toilet, go for a 5–7-inch stool. It keeps your legs lifted without compressing the knees.
The older adult or post-surgery patient
Balance and joint safety matter here. A lower stool — around 4–6 inches — prevents over-bending while still easing strain on the rectum. Non-slip bases and contoured tops are non-negotiable for stability.
Families sharing one bathroom
In shared spaces, consider an adjustable or stacking stool, like the ones available at Squatty Potty Australia. Adjustable heights allow every family member — from kids to grandparents — to find their ideal position safely.
Common Mistakes to Avoid
Even the best stool can fail if it’s used incorrectly. Here are the traps to avoid:
Going too tall too fast – If your knees feel compressed or you’re leaning excessively, lower the height.
Lgnoring Toilet Height – A stool that’s perfect for one toilet may be uncomfortable on another.
Skipping Stability Checks – Always test grip and base stability before each use. A wobbly stool is a safety hazard.
Over-straining Anyway – Remember, the goal is relaxation, not force. Let posture do the work.
Neglecting Regular Cleaning – Bathroom bacteria thrive on damp surfaces; gentle cleaning protects both hygiene and stool longevity.
Expert Insight: What health professionals say
Physiotherapists and pelvic health experts have long observed the benefits of squatting posture.
Dr. Megan Hall, a Sydney-based pelvic floor physiotherapist, explains:
“When we mimic the natural squatting angle, we remove resistance from the rectal canal. This small shift allows the bowels to empty more completely and with less effort — a critical change for anyone managing chronic constipation or haemorrhoids.”
She adds that stool height plays a role similar to choosing the right ergonomic chair at work:
“If your knees are too high, you’ll strain your hips; too low, and your rectum stays kinked. The key is comfort and alignment.”
These professional observations echo what research confirms — stool height fine-tunes the posture that your digestive system relies on.
Safety and Design Considerations
When choosing your stool, look for:
Anti-slip Rubber Grips — for both feet and floor.
Rounded Edges — to avoid knocks and bruises.
Wide Base Support — to handle movement safely.
Durability — moisture-resistant materials like high-density plastic or bamboo.
Ease of Storage — curved designs that tuck neatly around the toilet base.

The Bigger Picture: Why height isn’t “just a detail”
Choosing the right stool height might sound trivial, but it affects your:
Digestive Efficiency – Better alignment encourages smoother elimination.
Pelvic Floor Health – Less downward pressure protects long-term function.
Colon Clearance – Reduces residual waste that can contribute to bloating or constipation.
Toilet Time – Many users report cutting their time on the toilet nearly in half.
This is more than a convenience upgrade — it’s a meaningful step toward daily gut wellness.

FAQs
Q. How do I know if my toilet stool is too tall?
Ans. If you feel strain in your knees, hips, or lower back, or if you need to hold onto the toilet for balance, it’s probably too tall.
Q. Can kids and adults use the same toilet stool?
Ans. Yes, but ideally an adjustable-height or two-tier stool works best. Each user can adapt the setup for comfort and safety.
Q. Are toilet stools recommended for people with IBS or constipation?
Ans. Absolutely. Many gastroenterologists recommend toilet stools to reduce straining and support more complete bowel emptying, which helps manage symptoms of IBS and chronic constipation.
Q. Can a toilet stool help prevent haemorrhoids?
Ans. Yes. By reducing straining during bowel movements, toilet stools can help prevent or ease haemorrhoid flare-ups.
Q. How often should I clean my toilet stool?
Ans. At least once a week. Use mild soap and warm water — harsh cleaners can erode anti-slip coatings.
