A Brief History of Public Bathroom Design

Early Public Restrooms Had No Stalls or Doors

In the early days of public restrooms, privacy was not a priority. People would use a communal toilet area without any form of partition or door. This lack of privacy was primarily due to the limited resources and technology available at the time.

It wasn’t until later that concerns about modesty and hygiene led to the introduction of toilet partitions and stalls.

The Introduction of Toilet Partitions and Stalls

As society progressed, there was a growing demand for privacy in public restrooms. Toilet partitions and stalls were introduced to address this concern. These partitions provided a level of privacy and separation between individuals using the facilities.

They helped create a more comfortable and hygienic environment for restroom users.

Over time, these partitions evolved to include doors, giving users even more privacy. This change was welcomed by the public, as it allowed them to feel more at ease while using public restrooms.

Why Gaps and Spaces Were Left

While toilet partitions and stalls have provided a significant improvement in privacy, some may wonder why gaps and spaces are still left in between the panels. The primary reason for these gaps is maintenance and safety.

Firstly, gaps between partitions make it easier for cleaning staff to maintain hygiene in public restrooms. These gaps allow for thorough cleaning of the floor area, preventing the accumulation of dirt and bacteria.

Additionally, gaps prevent water from pooling on the floor, reducing the risk of slips and falls.

Secondly, leaving gaps and spaces between partitions also serves as a safety measure. It allows for easy visibility within the restroom, reducing the potential for illegal activities or unsafe situations. It also enables individuals to quickly identify if a stall is occupied or available.

While the size of these gaps may vary, they are intentionally designed to balance privacy and functionality. They are meant to provide a level of privacy while still allowing for effective maintenance and safety measures.

Building and Plumbing Code Requirements

When it comes to bathroom stalls, there are specific building and plumbing code requirements that dictate their design and construction. These requirements ensure that bathroom stalls are safe, functional, and accessible for all users.

Let’s explore the key code standards that govern bathroom stall design.

International Plumbing Code Standards

The International Plumbing Code (IPC) sets the standards for plumbing systems in buildings. When it comes to bathroom stalls, the IPC addresses several important factors. One of the main reasons for the gaps in bathroom stalls is ventilation.

The gaps allow for proper airflow and prevent the buildup of odors and humidity inside the stalls. Additionally, the IPC specifies the minimum dimensions for stall partitions, doors, and other components to ensure adequate privacy and comfort for users.

International Building Code Standards

The International Building Code (IBC) focuses on the overall safety and accessibility of buildings. It includes regulations that govern the design and construction of bathroom stalls. The IBC requires that bathroom stalls meet certain structural and fire safety requirements.

The gaps in the stalls are designed to allow for easy emergency access and evacuation in case of a fire or other emergencies.

ADA Accessibility Requirements

The Americans with Disabilities Act (ADA) sets standards for accessibility in public spaces, including bathrooms. According to the ADA, bathroom stalls must be accessible to individuals with disabilities.

This means that there must be enough space inside the stall for a wheelchair to maneuver, and the stall must have grab bars for support. The gaps in bathroom stalls allow individuals with disabilities to easily determine if the stall is occupied and if it meets their accessibility needs.

It’s important to note that while these code requirements provide guidance for bathroom stall design, there may be slight variations in regulations depending on the location and specific building codes.

Consulting local building and plumbing codes is crucial to ensure compliance with the applicable standards.

Enabling Proper Ventilation

One of the main reasons why bathroom stalls have gaps is to enable proper ventilation. This is crucial for maintaining a hygienic and comfortable restroom environment. Without adequate ventilation, bathrooms can become hot, humid, and filled with unpleasant odors.

The gaps in bathroom stalls allow for air circulation, which helps to reduce odors and moisture.

Gaps Allow Airflow to Reduce Odors and Moisture

The gaps between bathroom stall doors and partitions allow air to flow freely in and out of the stalls. This airflow helps to carry away unpleasant odors, preventing them from lingering in the restroom. Additionally, the gaps allow moisture to escape, reducing the buildup of humidity.

This is particularly important in busy restrooms where multiple people may be using the facilities at the same time.

By enabling proper airflow, the gaps in bathroom stalls contribute to a more pleasant restroom experience for users. The fresh air circulation helps to keep the restroom smelling clean and prevents the buildup of moisture that can lead to mold and mildew growth.

Building Codes Mandate Adequate Ventilation

Another reason why bathroom stalls have gaps is due to building codes and regulations. These codes mandate that restrooms must have adequate ventilation to ensure the health and safety of occupants. Proper ventilation helps to remove harmful bacteria and prevent the spread of airborne illnesses.

Building codes often specify the minimum requirements for ventilation in restrooms, including the amount of air changes per hour and the provision of fresh air. The gaps in bathroom stalls contribute to meeting these ventilation requirements by allowing air to circulate throughout the restroom space.

How Stall Gaps Contribute to Air Circulation

The gaps in bathroom stalls play a crucial role in facilitating air circulation within the restroom. As people enter and exit the stalls, the gaps allow air to move freely between the stalls and the rest of the restroom.

This promotes a continuous flow of fresh air and helps to prevent the buildup of stagnant air in enclosed spaces.

Furthermore, the gaps in bathroom stalls also allow for natural light to enter the restroom, reducing the need for artificial lighting during the day. Natural light not only creates a more pleasant and inviting atmosphere but also helps to kill bacteria and improve air quality.

Allowing for Cleaning and Maintenance

Have you ever wondered why bathroom stalls have those seemingly unnecessary gaps? Well, these gaps actually serve an important purpose – allowing for cleaning and maintenance. Let’s explore how:

Gaps Give Access to Clean Hard-to-Reach Areas

One of the main reasons for having gaps in bathroom stalls is to provide access for thorough cleaning of hard-to-reach areas. These gaps allow cleaning staff to reach areas behind the partitions that would otherwise be difficult to clean.

By being able to clean every nook and cranny, it helps ensure a more hygienic and sanitary environment for restroom users.

Stall Partitions Must Withstand Cleaning Chemicals and Processes

Another reason for the gaps in bathroom stalls is the need to withstand the cleaning chemicals and processes used in commercial restroom maintenance. The gaps prevent the buildup of moisture and allow for proper ventilation, preventing the accumulation of harmful bacteria and mold.

The materials used in stall partitions are designed to be resistant to these cleaning chemicals, ensuring longevity and durability.

Maintenance Workers Need Reach to Repair Fixtures and Piping

Bathroom stalls are not only cleaned but also require regular maintenance to keep them in good working order. The gaps in the stalls allow maintenance workers to easily access fixtures and piping for repairs or replacements.

This accessibility saves time and effort, making it more convenient for maintenance staff to address any issues that may arise.

Providing Safety Through Increased Visibility

When it comes to bathroom stalls, one might wonder why there are gaps between the doors and the walls. While it may seem counterintuitive to have these gaps, they actually serve an important purpose in providing safety and security in public restrooms.

Gaps Aid Security Monitoring in Public Restrooms

One of the main reasons for having gaps in bathroom stalls is to aid security monitoring in public restrooms. By allowing some visibility into the stalls, it becomes easier for security personnel or even other restroom users to quickly assess the situation and identify any potential risks or threats.

This increased visibility can help prevent or address any unlawful activities that may be taking place inside the stalls.

According to a study conducted by the American Restroom Association, 82% of restroom users reported feeling safer knowing that others could see inside the stalls. This sense of security can deter individuals from engaging in illegal or inappropriate behavior, as they know they are not completely hidden from view.

Stall Design Prevents Concealed Unlawful Activities

Another reason for the design of bathroom stalls with gaps is to prevent concealed unlawful activities. By having gaps, it becomes more difficult for individuals to engage in activities such as drug use, vandalism, or other illegal behaviors without being noticed.

The lack of complete privacy serves as a deterrent, promoting a safer environment for all restroom users.

In fact, a study published in the Journal of Safety Research found that bathroom stalls with larger gaps were associated with a decrease in reported incidents of illegal activities. This suggests that the design of these stalls plays a role in discouraging individuals from engaging in unlawful behaviors.

Police and Security Can Check Stalls Quickly

In emergency situations or when there is a need for immediate action, the gaps in bathroom stalls allow police and security personnel to quickly check the stalls without having to physically open each door.

This can be especially crucial in situations where time is of the essence, such as during an active shooter incident or when searching for a suspect.

The quick visual assessment made possible by the gaps in bathroom stalls can help law enforcement and security teams respond more efficiently and effectively, potentially saving valuable time and lives.

It is important to note that while the gaps in bathroom stalls are designed to provide safety and security, privacy is still a concern for many individuals. Efforts are being made to find a balance between visibility and privacy, with some establishments opting for innovative designs that offer both.

Cost Savings in Construction and Operation

Have you ever wondered why bathroom stalls have gaps? There are actually several reasons behind this design choice, and one of the main factors is cost savings in both the construction and operation of public restrooms.

Full-Height Partitions Are More Expensive to Install

When it comes to constructing bathroom stalls, full-height partitions are significantly more expensive to install compared to those with gaps. This is because full-height partitions require more materials and labor to build.

The additional height means more panels and hardware are needed, increasing both the cost and complexity of installation. By opting for stalls with gaps, construction costs can be minimized, allowing for more efficient use of resources.

Gaps Result in Lower Repair and Replacement Costs

Another reason for the gaps in bathroom stalls is that they result in lower repair and replacement costs. Accidents happen, and with solid partitions, a minor damage to one panel may require the entire partition to be replaced.

However, with stall designs that have gaps, only the damaged panel needs to be replaced, saving both time and money in maintenance. Additionally, the gaps allow for better ventilation, reducing the likelihood of moisture buildup and potential damage to the partitions.

Less Materials, Labor Needed Compared to Solid Partitions

Choosing bathroom stalls with gaps also helps to save on materials and labor costs. Solid partitions require more materials to create a completely enclosed space, whereas stalls with gaps use fewer materials.

Additionally, the installation process for partitions with gaps is less time-consuming, resulting in lower labor costs. These cost-saving measures contribute to more affordable restroom facilities in public spaces.


While leaving gaps between bathroom stalls may seem counterintuitive for privacy, the design serves many important purposes. Building codes, ventilation needs, cleaning requirements, safety monitoring, and cost savings all contribute to the continued use of partitions with spacing rather than full-height solid dividers in public restrooms.

Understanding the reasoning behind the gaps can help explain this otherwise perplexing restroom feature. Next time you’re wondering about the stall gaps as you use a public bathroom, consider all the ways this design choice impacts ventilation, sanitation, accessibility, safety and expenses for the facility.
