When we think about cutting-edge innovation, we don't usually think about humpback whales. And when we picture high-performance shower safety in our minds, I don't think it instantly throws up visions of 40-tonne marine mammals cutting through the waves.
But now, perhaps it might.
Stay with me here because, believe it or not, the same principles that help a humpback whale move with surprising ease through the ocean despite its size also help keep you upright and safe on your SENSTEC anti-slip shower at home.
Let me explain.
Let's start with SENSTEC.
If you've ever slipped in the shower or had one of those heart-stopping near misses, you'll completely understand just how dangerous a wet, soapy surface can be.
Now, traditional anti-slip shower trays attempt to mitigate the risk of slipping in the shower by using rough coatings or paint solutions on the surface that, while grippy at first, tend to wear off over time. As a result, they trap dirt and then become a bit of a nightmare to clean.
And ironically, a dirty anti-slip surface becomes instantly slippery again.
This is precisely the problem that shower tray manufacturer Classic Marble set out to solve. Not by adding something on top of the shower tray but instead by completely rethinking how an anti-slip surface should work.
Instead of coatings, they engineered a pattern of small, shallow dimples directly into the tray itself, with the largest tray having over 6,000 dimples. Pretty impressive, eh!
These dimples aren't just random bumps on the surface. Every single one is meticulously designed, right down to their height, shape and spacing. This dimpled design, patented in the UK, Europe, and the United States, was refined through 42 different prototypes with the help of the aerospace tooling industry, resulting in a surface that not only delivers exceptional grip but also feels comfortable to stand on. In fact, a study commissioned by the University of Ulster in Northern Ireland found that one user described the feeling of standing on the tray as "massage-like", while another likened it to "like reflexology for your feet", and subsequent real-world reviews confirm they weren't wrong.
But here's where things get interesting because SENSTEC isn't just about traction and comfort; it's about how fluid, ie. water, soap and grime, moves across the surface. And that's where we start edging into whale territory.
Enter the Humpback Whale
I think we will all agree that humpback whales are magnificent creatures. They're huge but also incredibly graceful. If you watch one swim, the chances are you'll see agile turns and acrobatic leaps out of the water.
All of this is made possible, in part, by a strange feature on their flippers called tubercles.
Tubercles are the bumpy ridges you'll find along the leading edge of a humpback's flipper. And for years, scientists couldn't quite figure out why they were there. They looked out of place. They interrupted the smooth, aerodynamic line we're so used to seeing on wings and fins.
When scientists began researching and testing them, what they found was astonishing. These bumps didn't create drag - they reduced it. The tubercles helped the whale stay in control at high angles of attack, delayed stalling, and even increased lift. In one study, the aerodynamic performance improved by over 100% in the post-stall region. In simple terms, it meant that the whale could turn tighter, swim faster, and do it all more efficiently.
All of this, from what initially looked like a flaw in the design.
Turns out, it was just nature being brilliant.
So... What does that have to do with your SENSTEC shower tray?
Well, I recently had a conversation with a "real life" scientist about SENSTEC, and they casually threw into the conversation, "You do realise this is doing exactly what the humpback whale's flipper does, right?" I laughed, "Tell me more".
The conversation continued and they ultimately led me to a paper about the biometric design of leading-edge tubercles.
At first, it sounds like a stretch. But think about it: both the humpback whale and the SENSTEC anti-slip shower tray use small, raised, non-random bumps to influence how fluid moves across a surface.
On the whale, it's water flowing along a flipper at speed. On a SENSTEC shower tray, it's water, soap, and whatever else the day throws at you, flowing toward the drain. In both cases, these bumps create tiny swirling eddies, or controlled turbulence. In the right conditions, turbulence can help things stay clean, stable, and efficient.
In SENSTEC's case, those micro-eddies are helping lift soap residue and dirt off the surface. Water flows around each dimple and carries debris away, which prevents buildup in the first place. The SENSTEC anti-slip shower tray is self-cleaning in a very real and very clever way. And so, by the same standard as before, a clean shower tray is a safer shower tray.
Now, I'm not saying Classic Marble developed the SENSTEC shower tray by copying the humpback whale. And I'm definitely not saying that the humpback whale evolved by studying anti-slip shower trays. But what I am saying is that both are using the same underlying physics, and for me, that's something worth celebrating.
Science. Comfort. Wellness.
It's so easy to talk about bathroom products in terms of practicality. Safety, cleanliness, maintenance. SENSTEC ticks all three boxes. But if we stop there, we can miss the bigger picture.
Because what the SENSTEC anti-slip shower tray really represents is biophilia. The human pull toward natural forms and systems that just work. The dimples on the SENSTEC tray aren't just functional, they're a nod, conscious or not, to the fact that nature has already figured a lot of this stuff out.
It's easy to think of science and nature as opposites. But here, they come together. SENSTEC's design wasn't inspired by the whale's flipper, but it ended up sharing Mother Nature's genius. That says something about good design. About engineering that works with the flow of water, not against it.
The world is evolving and I feel we're being drawn by an increasing energy into rethinking how we live, move, and build - reconnecting to nature, to proven patterns and the Earth's own problem-solving.
So, if you own a SENSTEC anti-slip shower tray.
Take a second to think about what's happening beneath your feet.
Those thousands of tiny, perfectly placed dimples. They're working in the background, keeping you upright, keeping things clean, and doing it all using principles that echo across oceans and species.
It's a bit of engineering, a bit of biology, and a bit of magic.
SENSTEC is not just another anti-slip shower tray, but instead, a quiet marvel of fluid dynamics, design, and natural brilliance all working together to make your daily routine safer and just a little more remarkable.
