Public Restroom

Everything about designing a public restroom layout

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!

Sink Dimensions

Sink dimensions and typologies vary widely:

Countertop sink sizes range between 40x40 cm / 15.7"x15.7" to 46x91 cm / 18.1"x35.8"
Wall-mounted sinks range between 25x40 cm / 9.8"x15.7" to 35x60 cm / 14.2"x23.6"
Corner sinks range between 45x45 cm / 17.7"x17.7" to 60x60 cm / 23.6"x23.6"

Toilet & Urinal Dimensions

Public toilet and urinal sizes vary depending on the design and manufacturer.

A monoblock toilet size is roughly 75x60 cm / 29.5"x23.6".
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".
The toilet should always be centralized in an 80 cm / 31.5" clearance space for comfortable use.

Toilet Stall Dimensions

Dimensions of standard and accessible toilet stalls depend on local building codes and requirements; follow those closely or consult an expert to get them right!
