When it comes to things that the germ-conscious want to avoid touching, toilet flush levers likely occupy the top spot. Kohler evidently realizes this, as it now offers a retrofit kit that allows buyers to flush their existing toilet without touching it.

At the heart of the Touchless Flush Kit is a module that mounts inside the tank via a metal bracket. That module projects an electromagnetic field into a space above the tank – a raised decal on the tank lid lets users know exactly where that field is.

When they subsequently pass their hand through the field, the module detects it and responds by raising an arm on its side. That arm serves the same purpose as a flush lever, as a chain runs from it down to the toilet's existing flush system.

The module runs on a set of four AA batteries, that should last for 6 to 12 months depending on how much action the toilet sees. And if users don't want the now-useless flush lever to still be hanging there looking germy, it can be removed and replaced with an included hole cover.

The Kohler Touchless Flush Kit should be on the market soon, priced at around US$100. It's reportedly compatible with "almost any single-flush toilet with a canister or flapper type flush."

Would be awesome if they hooked a turbine up to the inlet valve so the water refilling the tank could power the device.

I'm saying that off the top of my head, the maths probably doesnt add up.


Great - now all you need for a fully no-touch toilet is someone to lift the lid before you go and put it down again before you use the touchless flush...


A couple of decades ago, a company sold a device that hooked onto the standard flush lever. A shaft extended down to the floor, where a treadle provided the force to pull the lever. Just step to flush. No batteries and a lot cheaper than $100.


Considering that a user normally will (or should do) wash their hands after use anyway, this seems a waste of money. The price would buy a far amount of hand-wash or soap as well, let alone thinking about that funny feeling just after the shops close and the battery pack dies! LOL

Considering it's your own excreta your flushing, normal hygiene takes care of any problems.

For public toilets it's a good idea and I've seen contactless systems in use in several hospitals in the UK.

Alternatively as previously suggested use a foot pedal.

Shouldn't be that hard to make it a dual flush, wave your hand once for small flush, twice for full flush. Big issue for me is that the tank top is the place where the tissue box sits, so I will be flushing every time I need a tissue.... Agree, foot flush for public, but this is just a cute thingie for the home.

Is it ethical to exploit obsessive-compulsives in this way??


I think it is the first sign of the apocalypse but I agree with nutcase.
