Everything about designing a public restroom layout

Public Restroom

A public restroom is more than just a functional space; it reflects a community's commitment to the well-being and comfort of its members and visitors. Designing this layout requires careful consideration of various elements, like adequate space for stalls, urinals, sinks, and hand dryers, to minimize waiting times and ensure smooth traffic flow. It's important to follow official regulations for public restrooms, which can vary by location. Consult an expert to ensure you are creating a proper layout!

A floating toilet size is approximately 35x50 cm / 13.8"x19.7", and a floating urinal size is 38x40 cm / 15.0"x15.7". In both cases, a basin is installed in the wall behind it that ranges between 7-20 cm / 2.8"-7.9".

A benchmark compact public toilet stall is 80x155 cm / 31.5"x61.0", and a spacious one can reach 90x160 cm / 35.4"x63.0".
Accessible toilet stalls range from 150x220 cm / 59.9"x86.6" to 225x190 cm / 88.6"x74.8" and require a minimum of 150 cm / 59.1" floor space radius to allow for the maneuverability of a wheelchair.
