During the street Carnival that kicked off on Saturday, February 14, 2023, insufficient portable toilet facilities became a significant issue in Brazil's major cities, particularly Rio de Janeiro and São Paulo. Revelers in Rio faced wait times of up to 30 minutes in intense heat, especially in high-traffic areas. In São Paulo, while there were some support structures in central locations, the number of toilets along the parade routes was deemed inadequate, prompting some attendees to relieve themselves in public spaces.

São Paulo's administration, led by Mayor Ricardo Nunes, indicated that the plans for the 2026 street Carnival initially accounted for 16,000 rental portable toilets, although this amount could increase based on demand. However, the city has not provided specific details regarding any potential increase in the toilet facilities, leaving many concerns about sanitation and public health during such a large event unaddressed. Complaints began surfacing on the first day of the carnival and continued on Sunday, particularly in the bustling central region where the largest number of blocks gathered.

The lack of adequate restroom facilities raises important questions about urban planning and the organization of large public events in cities. It reflects broader issues of infrastructure and public health management, especially during major celebrations that attract significant crowds. Ensuring proper sanitation facilities is crucial for the comfort and safety of participants, and local governments may need to reevaluate and enhance their event planning strategies to avoid similar pitfalls in the future.
