The hours your safety rails can't reach

Most serious falls happen after dark — when they can't see the rail they're reaching for.

Grab rails, mats and adaptations protect your parent while they're awake and alert. But depth perception fades with age, and at 2am in an unlit bathroom, even a well-adapted room becomes a hazard. The light needs to arrive before they do.

How it works

Automatic protection that asks nothing of them.

The best safety devices are the ones a person never has to think about. Derythm works on its own, every time.

1

They stand — the light is already there

A motion sensor triggers a soft, adjustable glow the moment they get up. Bright enough to see the floor and the rails. Dim enough not to wake them fully.

2

They flush — it cleans itself

After every flush, hospital-grade UV-C runs automatically across the seat and bowl. No chemicals, no scrubbing, no waiting on the next deep clean.

3

You fit it once in 60 seconds

Peel, stick, done. It clips onto almost any toilet — no plumber, no contractor, no tools. Then it simply looks after them, night after night.

The signature moment

The light finds them before they find the switch.

No blinding overhead bulb at 2am. No hand searching the wall. Just a warm, low glow that appears exactly when it's needed — so the walk to the bathroom stops being the most dangerous part of the night.

The threat you can't see

A toilet seat rebuilds bacteria within a day of cleaning.

Even the most diligent carer can only deep-clean two or three times a week. In between, surfaces build up bacteria that a weakened immune system struggles with — a common trigger for the infections that put older people in hospital. Derythm's UV-C runs after every single flush, so cleanliness never waits for the next visit.

Why the cheap ones get returned

Not all "toilet night lights" are the same.

Families who stopped dreading 2am.

★★★★★

"Her carer said it's the only one she trusts. Within a week Mum stopped dreading getting up in the night — and hasn't had a single stumble in four months. The self-cleaning was a bonus I didn't even know I needed."

★★★★★

"We'd spent a fortune on grab rails. A retired nurse told us about the Derythm. He hasn't fallen once since we fitted it five months ago — his GP even commented on how much steadier he is."

Patricia K. Kent · Verified buyer
★★★★★

"After Mum's third UTI in a year we tried UV sanitation. Seven months on, not one since. The night light was an unexpected blessing — she gets up whenever she needs now. Still in her own home. That's everything."

Questions, answered

Everything you're wondering.

Yes — Derythm is designed to clip onto almost any standard toilet. It attaches in about 60 seconds with no tools, no plumber and no adhesive that damages the surface.

The UV-C cycle only runs with the lid closed and stops automatically if the lid is opened, so there's no exposure during normal use. It's the same sanitising technology used across care facilities.

No — that's the point. The glow is soft and adjustable, designed to light the way without the jarring brightness of an overhead bulb, so they can get back to sleep easily.

Derythm is rechargeable and lasts for weeks on a single charge, so there are no wires to trip over and no batteries to keep replacing.

You're covered by a 30-day money-back guarantee. Fit it, try it for a full month, and if it isn't right, return it for a full refund.

Don't wait for the second fall

Give them the safest night's sleep in years.

60 seconds to fit. Automatic protection that works while everyone's asleep — because your parent shouldn't have to gamble on their safety every time they get up in the night.
