Do Mobile Toilets Have an Odor?

Mobile toilets may have odor issues, but these can be effectively reduced through proper setup and management.

Whether mobile toilets produce odors depends on various factors. Firstly, usage frequency and the number of users. At large-scale events like concerts, with a large number of attendees, mobile toilets are used extremely frequently. When a large number of people use them in a short period, if cleaning is not timely, waste can accumulate, quickly generating unpleasant odors. For example, at G.E.M.'s concert at the Taizhou Sports Center Stadium in Zhejiang, dozens of mobile toilets were placed near the seating areas in the inner field. Due to concentrated use by the audience, many complained about the strong odor of the mobile toilets, saying things like, 'The whole night was filled with wafts of fragrance, and I watched the whole concert in a stinky state' and 'I was accompanied by a strong stench throughout, and it made my eyes hurt'.

Secondly, the design and ventilation of the toilets. Some simple mobile toilets have inadequate ventilation systems, and odors cannot be discharged in a timely manner, accumulating inside the toilet and resulting in a strong smell. In contrast, well-designed mobile toilets with good ventilation can effectively circulate air, expel odors, and reduce the residual odor inside.

Thirdly, the timeliness of cleaning and maintenance. Regular cleaning of mobile toilets, timely removal of waste, and replacement of sanitary products can effectively control the generation of odors. If cleaning is not done properly, the odor will keep getting worse.

However, nowadays, some concerts are reducing odor impacts by properly setting up mobile toilets. For example, at the 2024 Joker Xue's tour concert in Qujing, 50 independent mobile toilets were set up in front of the inner-field LED screen. At the 2023 Mayday concert in Shanghai, multiple mobile restrooms were placed in the VIP audience inner field and next to the stage control console, ensuring an adequate number and reasonable distribution. Such arrangements make it easier for the audience to find toilets, avoid gatherings near the toilets due to long waiting times, reduce the accumulation of odors in local areas, and also facilitate ventilation and cleaning work, thereby reducing the impact of odors from mobile toilets on the audience.
