The design is commonly known as a washout toilet, a style that has historically been found in countries such as Germany, Austria, the Netherlands, and several parts of Central and Eastern Europe.
Unlike standard North American toilets, which have a larger water-filled basin directly beneath the seat, washout toilets feature a shallow porcelain platform positioned above a smaller water area and drain opening.
When the toilet is flushed, water flows through the bowl and carries waste into the drain.
It’s a completely different approach to a task most people never think twice about.
Why Was It Designed This Way?
The washout toilet wasn’t created simply to look different.
Its design offered several practical advantages that appealed to many households.
Easier Visual Inspection
One commonly cited benefit is that the shelf allows users to visually inspect waste before flushing.
Historically, this was considered useful for noticing potential signs of digestive problems, parasites, or other health concerns at a time when routine medical screening was far less common than it is today.
Reduced Splashback
Many people appreciate the fact that the shelf design greatly reduces the chance of water splashing upward.
Anyone who has experienced an unexpected toilet splash understands why this became a selling point.
A Different User Experience
Because waste initially lands on porcelain rather than directly into water, the experience differs from that of conventional toilets.
For some users, this is a benefit.
For others, it takes some getting used to.
Why Isn’t This Design Common Everywhere?
If washout toilets offer advantages, why aren’t they used worldwide?
The answer comes down to preferences.
Over time, many homeowners and manufacturers shifted toward washdown toilet designs because they generally move waste more quickly into the water and often require less cleaning after use.
Modern toilet engineering has also improved splash prevention and hygiene, reducing some of the original advantages that made shelf toilets attractive.
As a result, washdown models gradually became the dominant design in many countries.
The Downsides Most People Notice
People encountering a shelf toilet for the first time often point out two drawbacks.
More Frequent Cleaning
Because waste lands on a dry porcelain surface before being flushed away, visible residue is more common.
This means the toilet brush tends to see more regular use.
Odor Can Be More Noticeable
In a traditional toilet, waste is immediately surrounded by water.
With a shelf design, there is less water coverage initially, which can make odors more noticeable until the toilet is flushed.
For this reason, longtime users often recommend flushing promptly after use.
A Clever Trick Many Users Swear By
In countries where shelf toilets are common, some people place a small piece of toilet paper on the porcelain shelf before use.
The paper acts as a simple barrier that may help reduce residue and make flushing cleaner.
While not necessary, many experienced users consider it a helpful habit.
What If You Drop Something?
One unexpected advantage occasionally mentioned by fans of the design involves dropped items.
If a ring, key, or small object accidentally falls into the bowl, it may land on the shelf instead of disappearing immediately into deeper water.
It’s not the reason the toilet was invented, but it can certainly save an awkward retrieval mission.
The Final Verdict
The mysterious shelf inside the toilet isn’t a defect, a storage ledge, or an unfinished design.
It’s a washout toilet—a plumbing style that has been part of everyday life in parts of Europe for generations.
While many people find it unusual at first, others appreciate its unique benefits and practical history.
Whether you love it or hate it, one thing is certain:
The first time you see a toilet with a built-in shelf, you’ll probably never forget it.
