In August, the $400 Nebia shower got people — including Apple CEO Tim Cook — excited with its promise to use 70 percent less water than your average shower head. That’s incredibly impressive, but Hamwells says its e-Shower beats that by 20 percent.

While the Nebia uses aerospace-grade spray nozzles that atomize water, allowing for a smaller volume of H2O to get you just as wet, the e-Shower recycles what normally goes down the drain. The used water gets filtered and mixed in with about 1.5 liters of fresh water each minute; that mixture gets hit with a UV light before raining down on your head again.

CEO Rob Chömpff said he was on a quest to make energy-neutral homes but found the shower to be a sticking point, which use around 2.5 gallons (10 liters) of water per minute. “Requiring 10 liters of warm water a minute for a sustained period, the traditional shower demands huge investments in solar panels, electric boilers and the like,” he said onstage at TechCrunch Disrupt London.

The app-controlled shower can also let you stream music and let you see how much money you’re saving in both energy and water cost. In addition to the 90 percent water savings, the shower should also reduce your energy consumption by 80 percent, the company says. The price of the shower is extremely steep: It starts at about $3,200 (2,950 euros), but CMO Wouter Chömpff says it has plans to send users the equipment and do the installation for free. They’ll still have to pay for it, but they’ll share their energy and water savings with Hamwells, and over the next two to five years, the company will recoup money from those savings. Pre-orders are starting now, with shipping expected in June.
