Barrier-Free Mobile Toilet

The barrier-free mobile toilet is constructed in accordance with relevant standards and is a dedicated facility designed specifically for special groups such as wheelchair users, visually impaired individuals, and the elderly.

I. Space Design Standards The space design of the barrier-free mobile toilet must meet the turning requirements of wheelchairs, with a standard area of no less than 4 square meters to ensure sufficient activity space for wheelchair users. The door design should consider ease of passage, with a clear opening width of at least 800mm. Outward-opening or electric sliding designs are preferred, and electric sliding doors must have anti-pinch features. If an inward-opening door is used, an emergency opening device must be provided to handle emergencies.

II. Internal Configuration Standards The internal configuration should balance safety and convenience. The toilet seat should be equipped with an L-shaped combination safety grab bar with a horizontal length of at least 700mm and a vertical height of 1.4 to 1.6 meters for easy gripping and support. The low-positioned sink should have a knee clearance of 650mm at the bottom to facilitate close operation by wheelchair users. The urinal should be equipped with a vertical grab bar and a horizontal auxiliary bar at a height of no more than 400mm to provide additional support. Additionally, an emergency call device should be installed in the toilet at a height of 0.4 to 0.5 meters from the ground to ensure that users can seek help promptly in case of an emergency.

III. Floor Plan Layout Types There are four typical types of floor plan layouts for barrier-free toilets: Type A is a 360-degree wheelchair rotation layout suitable for spaces with ample room; Types B/C are reverse-use layouts suitable for spaces with limited room but still requiring wheelchair rotation; Type D is a sliding door layout optimized for space, reducing the space required for door opening through a sliding door design and improving space utilization.

IV. Mobility and Flexibility Mobile toilets are not restricted by fixed buildings and can be flexibly deployed based on the density of foot traffic and the location of events. Whether in urban commercial areas, large exhibitions, or remote outdoor scenic spots, they can be quickly set up to promptly address people's toilet needs. This flexibility makes barrier-free mobile toilets an important supplement to the construction of barrier-free facilities in public places.
