Whether you’re fitting out a family bathroom, an ensuite, or an accessible washroom, understanding toilet height options will help you make the right choice for everyone who uses it.

In this post, I’ll explore the different toilet heights available, their pros and cons, and expert advice on choosing the perfect fit for your space.

What Are the Different Toilet Heights?

Toilet height is measured from the floor to the top of the toilet bowl rim (not including the seat). The seat itself usually adds another 20–30 mm.

There are three main categories of toilet heights found on today’s market:

• Standard Height
• Comfort or Chair Height
• Custom Height (usually wall-mounted)
  
  

Standard Toilet Height

This is the most common toilet height you’ll find in UK homes. Standard toilets typically measure 405–430 mm from the floor to the top of the bowl, though this varies slightly by manufacturer.

They’re comfortable for most adults, easy to find in any plumbing supplier, and generally the most affordable option.

✅ Pros of Standard Height Toilets

• Comfortable for most average-height adults
• Widely available in all styles (close-coupled, wall-hung, back-to-wall, etc.)
• Cost-effective and easy to replace
• Familiar height for most households
  
  

⚠️ Cons

• It can be too low for seniors or people with joint or mobility issues
• May be uncomfortable for taller users over long periods
  
  

Comfort (Chair) Height Toilets

A Comfort height toilet sits between 440 and 500 mm from the floor to the bowl rim, roughly the same height as a standard dining chair or wheelchair.

They’re designed to make sitting and standing easier and more natural, especially for those with limited mobility, knee pain, or arthritis.

Comfort-height models are sometimes referred to as chair-height toilets. They’re the same thing, just branded differently.

✅ Pros of Comfort Height Toilets

• Easier to use for older adults and people with mobility issues
• Ideal for taller users (6ft and above)
• Often ADA-compliant for accessible bathrooms
• Widely available in modern and traditional designs
  
  

⚠️ Cons

• May feel too tall for shorter users or children
• Slightly fewer design options compared to standard height
  
  

💡 In my opinion:
If this is a shared family bathroom, consider a standard height toilet unless accessibility is a top priority. For ensuite or mobility-focused bathrooms, a comfort height model is ideal.

Custom & Wall-Mounted Toilet Heights

If neither standard nor comfort height feels right, a custom height toilet may be the perfect solution.

Wall-hung toilets are especially versatile — they can be mounted at any height during installation, allowing for precise customisation to suit your body and comfort level.

Custom height doesn’t always mean taller. Shorter users can benefit from a lower-mounted wall-hung toilet that makes it easier to rest both feet flat on the floor.

✅ Pros of Custom Height Toilets

• Can be set to your exact comfort level
• Perfect for bespoke bathrooms or accessible wet rooms
• Wall-hung units create a modern, space-saving aesthetic
  
  

⚠️ Cons

• More expensive, often £500–£1,500+
• Custom orders can take longer to manufacture
• Installation requires skilled fitting and a solid wall frame
  
  

Why Toilet Height Matters

We use toilets every day, so getting the height right is essential for comfort, posture, and safety.

A toilet that’s too low can strain your knees and back when standing up. Too high, and your feet may dangle. Not only uncomfortable but also less stable, especially for shorter people.

The right toilet height should allow you to sit and stand naturally, with your feet flat on the floor and knees at a comfortable angle (around 90°).

💡 Fun Fact:
The typical toilet height of around 405–430 mm (16–17 inches) became widely adopted in the 20th century, as manufacturers standardised designs for comfort and plumbing efficiency. Accessibility standards introduced later, such as the ADA guidelines, helped popularise taller comfort-height models measuring around 430–480 mm.

Choosing the Right Toilet Height for Your Home

Ask yourself the following before choosing a toilet height:

1. Who will use the bathroom the most?
   • For a family bathroom, standard height works best.
   • For seniors or anyone with mobility issues, comfort height is ideal.
2. Is accessibility a priority?
   • Comfort height toilets meet most accessibility standards and pair well with grab rails.
3. How tall are you (or your main users)?
   • Taller users often prefer 460–480 mm for better comfort.
   • Shorter users may find anything over 450 mm awkward.
4. Is this a design-led project?
   • Wall-hung toilets allow total flexibility and a modern aesthetic.
     
     

💡In my opinion: Choosing the right toilet height is about more than comfort, it’s about safety, accessibility, and long-term usability. If multiple people use the same bathroom, aim for a height that works for the majority, and use accessories like raised seats or stools to adapt.

Final Thoughts

Toilet height might seem like a small detail, but it has a big impact on comfort, accessibility, and bathroom design.

For most homes, a standard height toilet works perfectly well. For seniors, taller individuals, or anyone with mobility challenges, comfort height or custom wall-hung models offer a smarter, safer solution.

When you’re planning your next bathroom upgrade, take a moment to sit (literally!) and find the height that feels right. Your knees, back, and future self will thank you!
