Arc Shower Water Flosser

The inspiration behind the ARC Shower Water Flosser came from a very personal place. I’ve struggled with dental issues in the past, largely because I didn’t have a consistent flossing habit. Like many people, I found it hard to integrate flossing into my daily routine — it always felt like a chore, and frankly, I often skipped it.I started thinking: what if we could make building healthy habits easier, more intuitive, and less of a hassle? That’s when the idea of combining flossing with an existing daily habit — showering — came to life. The shower is already a natural part of everyone’s routine, so integrating oral care into that time makes it nearly frictionless.Most flossing solutions on the market today are either expensive, bulky, or just inconvenient to use consistently. I wanted to create something that was simple, effective, and accessible — both in terms of usability and cost. The ARC Shower Water Flosser removes the barriers that often stop people from flossing, making it a natural extension of their daily routine.

The primary goal behind the 4-way water stream head design was to make flossing faster and more efficient without compromising on precision or effectiveness. Traditional single-stream flossers often require a lot of time and awkward maneuvering, especially when trying to reach the back teeth. We wanted to solve that.While the head features four strategically placed nozzles — two for the front teeth and two for the back — we intentionally designed it so that only two streams operate at any given time. This was a critical decision made for two main reasons: accuracy and water pressure.From a performance standpoint, using just two focused streams at once ensures that the water is directed precisely to the grooves between teeth, where it’s most effective. From an engineering perspective, this also allows us to maintain strong water pressure, even when relying on a standard shower connection. Activating all four streams simultaneously would have reduced pressure significantly and compromised cleaning effectiveness.The rear-facing water streams were an especially thoughtful addition. They solve a common pain point with traditional flossers: trying to twist or rotate the device at uncomfortable angles to clean the back teeth. Our dual-stream setup allows users to get a full clean — front and back — with minimal effort and without breaking their natural flow in the shower.Ultimately, the 4-way design is about efficiency, comfort, and delivering a complete clean, all while respecting the limitations of home water pressure systems.

Sustainability was definitely something we kept in mind throughout the design process. Traditional string floss creates a lot of waste — from the plastic cases to the floss itself, which is thrown out daily. With ARC, we wanted to minimize that. The flosser uses water from your shower and only requires a replacement head every 3 to 6 months, which helps cut down on waste.We also kept the design low-tech on purpose. There are no batteries, no charging, and no electronics involved, so it’s not only more durable but avoids the environmental impact of electronic waste. That simplicity also means fewer repair issues over time.Installation was another area where we tried to reduce waste. ARC connects directly to your shower without needing extra adaptors or complicated parts. And we use recycled materials in our packaging and keep it as minimal as possible.Overall, the goal was to make something that fits into people’s lives easily while being a little more thoughtful about its impact on the environment.
