Detailed Product Features
HEALTH
Clean Water Journey
120 mesh filter
The 120-mesh filter is built into the angle valve at the water inlet end, which effectively filters out small particles of impurities, such as rust and sand, in the water, making the water flow clearer.
UVC-Clean Water Technology
Before water flows to the heated tube, UVC light effectively reduces harmful microorganisms and purifies the washing water.
Deeping purification, helping ensure a clean, hygienic wash every time—a thoughtful upgrade for families, wellness seekers, and anyone who values a truly refreshing cleanse.
PlasmaClean Technology
Smart toilet features a built-in Plasma Generator that releases cleansing particles into the air, which disperse with the airflow from the fan to the toilet bowl, and around, effectively keeping it hygienic and improving health level.
Compared with the nozzle UVC purification and electrolytic water purification of traditional smart toilets, plasma purification is more comprehensive and more environmentally friendly.
Foam Shield
The HealthGuard Foam Shield forms a dense layer inside the bowl to prevent splashing, lock in odors, reduce waste adhesion, and maintain a hygienic environment, giving you a cleaner, more comfortable experience every time.
While typical smart toilets with Foam Shield feature release foam through a single outlet, releasing it directly onto the surface of the water in the toilet bowl.
The Uncle Brown ST12 combines Foam Shield with a Pre-wet function, allowing the foam to flow through every inch of the toilet bowl, making cleaning easier.

Powerful Silent Flush
Smart toilet features a built-in water submersible pump, delivering strong, MAP 1000g-certified flushing performance that effortlessly clears waste with minimal water 1.28GPF—no clogs, no stains, and lower noise.
Unlike other powerful flush smart toilets with built-in pumps, the Uncle Brown ST12 incorporates the pump into the tank. Just as it’s difficult to hear someone talking underwater on land, water isolation significantly reduces the noise of the pump during flushing.

- Auto-open/close lid
- STAA Toilet Seat
- Nozzle with Silver Ion

Deodorization opens when you sit down, and there is no odor at all, as if you have never been there.
Foam Shield | Silent Flush
No splashing, less odor, easy to clean, you want it all. Then this is it.
When the pump is submerged, a powerful flush does not necessarily mean a loud noise.

Seasons Temp Sensing
The Uncle Brown ST12 automatically adjusts its temperature(water, seat, and dry temperature) based on the ambient temperature when you activate its intelligent temperature sensing mode. This avoids unnecessary high temperature settings and reduces power loss.
Efficient Flushing
Compared to traditional toilets that consume 1.6 gallons of water per flush, the Uncle Brown ST12 uses only 1.28 gallons per flush, a 20% water saving. It complies with water conservation requirements such as cUPC, DOE, and CEC.
Air-in Water Wash
Using natural aspiration technology, about 30% of air is added to the water, reducing water consumption by about 30%. The air-infused water provides a higher level of comfort the moment it hits the skin.

Peter –
I have used a Japanese brand washlet toilet for decades, remodeling my downstairs bathroom. decided to give this brand a try, I am totally wowed by the build quality and features. The toilet bowl seems to have the same coating as top of the line Japanese washlets, it flushes very clean, I mean VERY clean. Auto flush is very quiet. Auto seat cover is very responsive. Seat warmer is a big plus. Now I can go bathroom without lifting finger, everything is automatically done. I have two more bathrooms to remodel, will definitely use this washlet toilet.
