For a decade, the smart shower category was essentially a thermostatic valve with an app stapled to it. Not particularly useful unless you consider “Hey Alexa, switch on my shower” to be the pinnacle of smart home automation. Essentially, the water itself still ran the same path it always had: supply line, showerhead, drain, gone. Kohler’s Anthem EvoCycle, announced February 2026 and shown live at KBIS, is the first product from a major fixture brand that questions what a smart bathroom should be. The answer? Something more than a voice-activated or app-controlled shower. Something more like a shower that recycles 80% of its water every time you bathe.
The magic lies in your bathroom’s subfloor. The EvoCycle’s recirculation loop lives 4.5 inches below your shower base in a purpose-built receptor sump, paired with a pump, an ozone sanitation system, and a closed filtration loop that processes your shower water and sends it back through the showerhead mixed with 0.5 gallons of fresh water per cycle. Kohler’s claim is 80% water savings at full flow pressure, and the design work required to make that claim feel like a regular shower experience instead of a sustainability-driven compromise is perhaps the most interesting part about this entire product’s UX.
Designer: Kohler
The system runs in two modes. Standard Mode is exactly what it sounds like: fresh water, normal shower, nothing unusual happening. Cycle Mode is where the engineering earns its keep. Once activated, the system fills the subfloor reservoir, then begins running that water through a closed filtration loop while continuously mixing in fresh input. The result hits the showerhead at full pressure, which matters enormously because the biggest psychological hurdle any recirculating system faces is the moment the flow drops and you suddenly become very aware that something unconventional is happening beneath your feet. Kohler clearly stress-tested that experience, because maintaining full pressure wasn’t a given. Orbital Systems, the Swedish company that pioneered residential recirculation technology from aerospace-derived origins, solved the same problem at roughly $3,995. Kohler’s full system comes in at $5,625 for the smart shower hardware alone, with the receptor base and installation on top of that. The price delta is smaller than you’d expect, but Kohler brings something Orbital never had: contractor relationships, showroom presence, and a brand name that appears on spec sheets without requiring an explanation.
The sanitation story is where the hidden complexity really accumulates. Recirculated shower water is only as good as what’s been done to it between uses, and Kohler’s answer is ozone. The system runs an automated Rapid Clean ozone cycle after every single shower, no pods, no chemicals, no user action required. A monthly Deep Clean cycle goes deeper, and the receptor filter pulls out for a dishwasher run. That maintenance architecture was clearly designed for the person who will never read a manual, which is essentially everyone. The Kohler Konnect app handles remote start, temperature control, water usage tracking, and cleaning cycle management, so the whole system is accessible without ever touching the wall-mounted digital control panel.
There are five receptor size options ranging from 48 by 32 inches up to 60 by 42 inches, left and right drain configurations, and four finish choices: Vibrant Brushed Moderne Brass, Polished Chrome, Matte Black, and Vibrant Brushed Nickel. The system is also compatible with any Kohler showerhead or rainhead, so you’re not locked into a specific spray experience. What you are locked into is the construction timeline. The subfloor cutout has to happen during the building or renovation phase, which means this is a conversation you have with your contractor before the concrete goes down, not after. For luxury new builds and serious bathroom renovations, that’s a manageable constraint. For anyone hoping to retrofit an existing shower over a weekend, it isn’t.
That construction dependency is also, in a strange way, the product’s strongest design statement. Kohler built something that requires genuine commitment, a system that can’t be undone with a screwdriver and an afternoon. The smart shower category spent a decade adding features you could turn off. The EvoCycle is a feature you build your bathroom around.
