ARC: Revolutionizing Oral Care with Shower Water Flossing

Innovative design merges oral hygiene with daily shower routines

ARC, designed by Allen Chou and Dosun Shin, introduces a sustainable and time-saving approach to oral care by integrating water flossing into the shower, catering to modern lifestyles seeking efficiency and convenience.

ARC stands out as a pioneering shower water flosser, seamlessly blending oral hygiene with the daily ritual of showering. Inspired by the desire to simplify routines and foster healthier habits, the design leverages existing shower water pressure, eliminating the need for electricity or batteries. This sustainable approach not only reduces environmental impact but also addresses the growing demand for eco-friendly personal care solutions.

The device features an ergonomic form and a replaceable 4-way water stream head, ensuring thorough cleaning between teeth and along the gum line. Users can easily adjust the water pressure to suit their comfort, choosing from three customizable settings for a gentle or intensive flossing experience. The compact, moisture-resistant storage station with magnetic attachment keeps ARC accessible yet discreet, maintaining both hygiene and aesthetic appeal in the bathroom.

ARC’s development was rooted in extensive design research, focusing on user behavior and product functionality. Interviews and market analysis revealed a clear preference for solutions that save time, require minimal maintenance, and are affordable. By addressing common pain points associated with traditional string floss and electric water flossers, ARC offers a compelling alternative for those prioritizing convenience and sustainability.

Technical innovation is evident in ARC’s construction, utilizing durable ABS plastic and silicone seals to withstand moisture and ensure longevity. The 4-way water stream head, crafted from BPA-free plastic and soft rubber, delivers comfort and effectiveness. The device’s reliance on shower water pressure means it operates with minimal energy, further enhancing its eco-friendly credentials.

ARC’s recognition with the Iron A' Design Award in 2025 highlights its excellence in merging practicality, innovation, and industry best practices. The award underscores its positive impact on both consumers and the broader medical and hospitality sectors, promoting healthier oral care habits while contributing to a more sustainable world.

By transforming the way oral hygiene is integrated into daily life, ARC sets a new standard for personal care products, demonstrating how thoughtful design can lead to meaningful lifestyle improvements.
