It covers the hours between cleanings — and lights your way while it's at it.
- 🦠 UV-C every time the lid closes. The same 253.7 nm wavelength hospitals use.
- 💡 Lights up when you walk in. Motion-activated, 3 brightness levels
- 🔋 60 days per charge. One minute to install.
Sentia works alongside your regular cleaning — it handles the hours in between, it doesn't replace them.
Your toilet gets used dozens of times between cleanings. Sentia covers those hours. Made for bathrooms where:
- ✓ Kids don't always aim — or close the lid before they flush
- ✓ Someone gets up at night and won't turn on the overhead light
- ✓ Scrubbing after every single use was never realistic
It sticks under the lid. Every time the lid closes, it runs a UV-C cycle over the bowl and seat. When someone walks up, a soft light comes on. Nothing to press, nothing to refill.
✨ Kills 99.9% of germs after every flush automatically.
One minute, no tools, nothing touching your plumbing. After that it runs itself.
- Step 1 — Stick it on Adhesive strip, under the lid, centered
- Step 2 — Pick your brightness One of 3 levels, set once
- Step 3 — Close the lid The UV-C cycle starts on its own, only with the lid down
Recharges over USB-C — around 8 weeks of normal use between charges.

Product Detail
🦠 It disinfects in the hours you can't
Close the lid and a UV-C cycle runs for 3 minutes — the same germicidal wavelength hospitals use for surface disinfection. No chemicals, no fumes, no scrubbing, nothing added to your list.
That's the gap nobody covers. A family toilet gets used 30 to 40 times a week. It gets properly cleaned twice. For the rest of the week you're using a toilet that was last disinfected days ago, and touched by everyone in the house since.
🌙 The light is already on when they walk in
A motion sensor watches the room while the lid is up. Someone walks in, the light is on — the bowl, the seat, the floor around their feet. No switch to find in the dark, no choosing between seeing where you're stepping and staying asleep.
It's deliberately dim. Bright enough for a three-year-old to aim by, soft enough that everyone goes back to bed and back to sleep.
🔒 The UV only runs with the lid closed
The sanitizing light physically cannot operate while the lid is open. Closed lid, cycle runs. Lid up, it's a night light and nothing else. No exposure to skin or eyes, ever — not your kids', not the cat's, not yours.
🎚️ Three brightness levels
Set it once when you install it and leave it. The level a toddler needs to see the bowl isn't the level an adult wants at 2 a.m. — you pick yours and never touch it again.
🧰 Installed in under a minute
Adhesive mount to the underside of the lid. No tools, no drilling, no plumber, nothing that voids a warranty. It sits out of sight and out of reach, and it fits standard round and elongated toilets.
🔋 60 days on one charge
Measured at 8 uses a day — a family bathroom usually does more. USB-C, charges in 2 hours. You unstick it, charge it, put it back. Roughly six times a year.
🤫 Nobody has to learn anything
No app. No remote. No buttons to remember at 2 a.m. Everyone uses the bathroom exactly the way they always have, and the device does its part on its own. That's the whole point: it disappears into the routine instead of adding to it.
Sentia isn't about specs. It's about the floor you're not wiping at 6 a.m., and the four days a week that toilet used to sit dirty between cleanings.

Self-Cleaning UV Toilet Sanitizer & Night Light
Their Words, Their Bathroom Experience
-
My three-year-old just started going to the bathroom on his own at night. I was cleaning the floor around the toilet almost every morning. He wasn't doing it on purpose. He just couldn't see. The blue light turns on by itself when he walks in so now he has something to aim at and the overhead light stays off which means he actually falls back asleep after. The sanitizing part is a bonus I didn't expect to care about this much. I still clean the bathroom on Sundays. It feels a lot less gross in between.
-
Mom broke her wrist falling at midnight trying to find the light switch. The light comes on by itself now when she walks in, so she can see without turning on the overhead one that used to blind her. She's sleeping better and she's not nervous about getting up anymore. Still living on her own at 72, and I'd like to keep it that way. So glad I got this.
-
I have a HEPA purifier in every room. I check labels on everything so having a bathroom that only felt clean because it smelled like chlorine was driving me crazy. Bleach fumes in a room with no window are not "clean" they're a different problem. This works with light instead of chemicals. The test card they provided was a touch. I was doubtful because you can't see UV working and that at least gave me something to check. One month in and the bleach is still sitting in the cabinet.
Every flush undoes your last clean.
Close the lid or leave it up, it doesn't matter much: a flush pushes a fine mist of whatever was in the bowl out onto the seat, the rim, and the handle. It settles in seconds. Nobody sees it happen.
Then the bathroom gets used again. And again. A family toilet gets used somewhere around 30 to 40 times a week. You clean it twice, maybe three times if you're the kind of person who notices these things.
So the honest math is this: for almost the entire week, you're using a toilet that was last disinfected days ago, and touched by everyone in the house since.
Sentia handles the part you can't.
It sticks under the lid in about a minute. From then on, every single time the lid closes, it runs a UV-C cycle at 253.7 nm — the same germicidal wavelength used in hospital disinfection — across the bowl and the underside of the seat.
No spray, no smell, no scrubbing, nothing to remember. It just runs, dozens of times a week, in the gaps where nothing else was happening.
And because it's already down there watching for movement, it gives you a soft light when you walk up at night. You'll stop reaching for the switch within a week.
What UV-C light is
It's light, not a chemical. A very short band of the ultraviolet spectrum — 253.7 nanometres — that hospitals, water treatment plants and labs have used for decades to disinfect without touching anything.
-
1
The light reaches the surface
Every time the lid goes down, Sentia runs a UV-C cycle across the bowl, the water and the underside of the seat.
-
2
It breaks the bacteria's DNA
At 253.7 nm the photons are absorbed by the microbe's own genetic material and fuse it together. The cell is left with instructions it can no longer read.
-
3
It can't multiply anymore
A bacterium that can't replicate doesn't rebuild a colony between one cleaning and the next. Nothing to scrub — the light does that part.
And why that takes the smell with it
Bathroom odour isn't dirt — it's gas. The bacteria living off the residue left in the bowl release sulphur and ammonia compounds as they feed, and that's what you're actually smelling.
Air freshener covers it for an hour. Sentia goes after the source: fewer bacteria on the surface means less of the gas they produce, so the bathroom stays neutral for longer between cleanings.
From published research on UV-C irradiation inside the toilet bowl. These are figures for the technology, not a test of Sentia itself.

FAQ's
Is the UV light safe around kids and pets?
Is the UV light safe around kids and pets?
The UV-C only operates with the lid closed. It physically can't run while the lid is up, so there's no way for the light to reach skin or eyes — theirs, yours, or a grandchild's. When the lid is up, Sentia is a night light and nothing else.
Do I have to do anything differently?
Do I have to do anything differently?
No. No app, no remote, no buttons. Lift the lid and the light comes on; close it and the cycle runs.
How bright is it? Will it wake them up?
How bright is it? Will it wake them up?
That's the whole design problem, and it's why Sentia has three brightness levels instead of one. You set it once when you install it — start on the lowest and move up only if they need more.
Even at the top setting it's bright enough to see the bowl, the seat and the floor at their feet, and not bright enough to reset their body clock the way a ceiling light does. Most people go back to bed and back to sleep.
Does it light the hallway or the path to the bathroom?
Does it light the hallway or the path to the bathroom?
No, and we won't tell you otherwise. Sentia lights the toilet area — roughly one square meter. If the walk from their bedroom is the part that worries you, you'd want motion-sensor lights along that route as well. This solves the part where they're turning, sitting and standing in the dark.
Will it fit my toilet?
Will it fit my toilet?
If the toilet has a lid, Sentia fits. It mounts to the underside of the lid with an adhesive pad, so the shape of the bowl, the brand and the model don't matter — round, elongated, one-piece, two-piece, all the same.
How long does the battery last?
How long does the battery last?
About 60 days per charge — measured at 8 uses a day, which is roughly what someone their age actually does. When it runs low you unstick it, charge it over USB-C in about 2 hours, and put it back. Around six times a year.
Does it replace cleaning the toilet?
Does it replace cleaning the toilet?
No. It handles the days in between. You clean twice a week; they use that toilet eight times a day. Sentia runs a disinfection cycle after every use so the surface isn't sitting untouched for three or four days at a stretch. You still clean — you just stop being the only thing standing between visits.
Can I gift it or set it up for someone else?
Can I gift it or set it up for someone else?
Yes, and most buyers do. Installation takes under a minute with no tools. Nothing needs configuring, pairing or connecting.
What if it doesn't work for us?
What if it doesn't work for us?
Try it for 60 nights. If it doesn't fit his bathroom, doesn't hold, or he simply doesn't take to it, return it for a refund in good condition. We'd rather have that than have you keep something that isn't helping.
Will the adhesive hold?
Will the adhesive hold?
It's a 3M-style adhesive mount rated for humid bathroom conditions, applied to the underside of the lid where there's no direct water contact. Clean and dry the surface before applying and give it an hour before first use. If it fails within your 60 nights, we replace the unit — not just the mount.
How does the 2-year warranty work?
How does the 2-year warranty work?
It covers technical faults in the device itself, for two years. If the motion sensor stops detecting, the UV cycle stops running, the light fails, or the battery no longer holds a charge, that's covered.
What it doesn't cover: drops, water damage, a unit that's been taken apart, or normal wear on the adhesive mount.
