Public restrooms have traditionally been afterthoughts in building design — functional but not beautiful. A new generation of designers is changing that, creating facilities that are safe, sustainable and even worth visiting.

Privacy Without Concealment

One of the core design tensions in public restrooms is privacy versus safety. Traditional full-height stall doors can conceal illegal activity. Modern designs address this through: staggered entry corridors that provide privacy without blind corners, slatted designs at top and bottom of stalls, open sink areas with clear sightlines, and bright, consistent lighting throughout.

Material Choices

Durable, low-maintenance materials are essential in public restrooms. Stainless steel is standard for high-traffic urban fixtures — it resists graffiti, corrosion and vandalism and can be cleaned with industrial solvents. Vitreous china (glazed ceramic) for toilet bowls and sinks is the traditional standard. Polypropylene surfaces resist scratching and disinfectant chemicals.

The Portland Loo and Modular Design

Portland, Oregon's modular Loo design has become a model exported to cities across North America. Key design principles: single-occupancy avoids gender designation complexity; open slats at 12 and 78 inches allow air circulation and visibility without compromising privacy; exterior plumbing prevents vandalism of pipes; standard dimensions allow prefabrication and consistent maintenance.

Tip: The term "comfort station" — used in many park systems — dates to the Progressive Era of the early 1900s, when park designers specifically used architectural language to dignify public toilet facilities and encourage their use.

Sensory Design

Forward-thinking public restroom designers consider the full sensory experience. Good ventilation eliminates odor more effectively than air fresheners. Acoustic design (absorbing materials, white noise) provides privacy. Warm lighting temperatures (compared to harsh fluorescent) create a less clinical environment. Natural light where possible dramatically improves the experience.

The Tokyo Toilet Project

The most ambitious public restroom design project in history is Tokyo's The Tokyo Toilet (2020–present), which commissioned internationally recognized architects to create 17 public facilities in Shibuya. Shigeru Ban's transparent glass restroom — which turns opaque when locked — illustrates how restroom design can comment on public space, privacy and urban life while remaining entirely functional.
