Somehow the toilets in bus stations and airports have technologically superseded the home commode. Toilets with motion sensors and water jets exist for civilian abodes, but they’re expensive to install and usually come with superfluous jets and LCD screens. This kit from Kohler can be installed without a plumber and, when finished, you can flush your standard toilet by briefly holding your hand a few inches above the tank. Available online, $100.
The main component is a motion sensor that goes inside the tank and triggers the flush cycle when it detects your hand. The four AA batteries that power it will last for a year.
Other sensors on toilets project a beam of light that, when a hand interferes, senses movement. Kohler’s system projects an electromagnetic field that they say is more accurate and reliable.
The automatic arm that raises and lowers the flapper can be set up so that it stays open for the correct amount of time each flush—that means never having to tell guests to jiggle the handle.
The kit comes with a sticker that you can set on the tank to indicate that it uses a touchless system.
Since a full touchless flush toilet from Kohler will cost upwards of $350, this $100 kit makes sense if you already have a functional but analog toilet. It looks best on a unit that has the handle mounted on the side since the included cover-up for the handle’s cut-out is just a small piece of white plastic.
