The Submarine Secret: Unveiling the Mystery of the Onboard Toilet!


The invention of the submarine revolutionized naval warfare, allowing underwater stealth and strategic maneuvering. However, the question of personal hygiene and the presence of an essential facility like a toilet on these confined vessels remains intriguing. For sailors stationed deep below the surface for extended periods, the absence of restroom facilities could present a significant challenge. Understanding the historical development of submarines and the technological limitations they faced provides a context for exploring how sailors managed their basic needs. This article investigates whether submarines were equipped with toilets or if alternative methods were utilized to address this fundamental aspect of human existence in the depths of the ocean.


  • Enhanced comfort and convenience: Having a toilet on a submarine provides the crew members with a higher level of comfort during their long missions underwater. It allows them to attend to their physiological needs more easily, ensuring their well-being throughout their deployment.
  • Improved hygiene and health: The presence of a toilet facilitates the proper disposal of waste, thereby maintaining a higher standard of hygiene on board. This helps prevent the spread of diseases and protects the health of the crew by minimizing the risk of contamination or infection.


  • Limited sanitation facilities: One disadvantage of submarines is that they typically have limited space and resources for sanitation facilities, including toilets. This can lead to inconvenience and discomfort for crew members who have to rely on limited toilet facilities or alternative methods of waste disposal.
  • Potential hygiene risks: The confined environment in submarines may pose hygiene risks due to the limited access to proper sanitation facilities. This can potentially result in the spread of germs and diseases among the crew, especially if stringent hygiene practices are not followed.
  • Psychological impacts: Another disadvantage is the psychological impact it may have on crew members who spend long durations in a submarine without access to spacious and normal bathroom facilities. The lack of privacy and potentially uncomfortable conditions can lead to increased stress and discomfort during their deployment, affecting their overall well-being.

  • Do submarines have restrooms?

    Yes, submarines do have restrooms, but they are not your typical toilets. Due to the high pressure and low gravity environment they operate in, submarines require specially designed toilets. These toilets use pressurized seawater to flush waste, ensuring it is efficiently disposed of. The waste is then stored in a holding tank until it can be processed. This innovative system allows submarines to maintain hygiene and cleanliness, even in the most challenging conditions deep beneath the ocean's surface.

    Submarines have specially designed toilets that use pressurized seawater to efficiently flush waste. This unique system ensures cleanliness and hygiene in the high-pressure, low-gravity environment they operate in. Waste is stored in a tank until it can be processed, allowing submarines to maintain a hygienic environment deep beneath the ocean's surface.

    What is the total number of toilets present on a submarine?

    On a fast-attack submarine, the total number of toilets available is 14. There are two bathrooms allocated for the crew members, each equipped with four toilets and two urinals. Additionally, there are three baths designated for crew chiefs and officers. Striking a balance between accommodating male and female crew members can be challenging, as reserving a bath exclusively for women may disadvantage men, while opting for unisex bathrooms presents its own set of issues.

    On a fast-attack submarine, the allocation of 14 toilets can be challenging to strike a balance between accommodating male and female crew members. Designating two bathrooms for crew members and three baths for crew chiefs and officers helps address this issue, avoiding any disadvantages for either gender.

    Did U boats have toilets?

    U-boats, infamous German submarines during World War II, did indeed have toilets on board. However, their usage was limited due to the cramped and challenging conditions faced by submariners. The U-505, for example, had two bathrooms, but one of them was utilized for storing food during the initial phase of the voyage. With a staggering 75% casualty rate, crew members had to forgo bathing for the entire two months at sea, relying instead on alcohol to clean themselves. Such sacrifices illustrate the harsh realities of life on board these dangerous vessels.
