Naval vessels do not have bathrooms or restrooms. They are called heads.
Pressurised seawater is used to flush the toilets on a submarine. A simple ball valve operates the flush on the toilet which enables the toilet to be 'plumbing free'. Once flushed, you then manually turn a valve next to the toilet to refill the bowl.
Waste that is discharged overboard must either be pumped out against the ambient sea pressure or blown out using pressurized air. Waste materials are collected and periodically discharged.
U-boat submariners had a 75% casualty rate, the highest of all German forces during the war. The U-505 had two bathrooms, one of which was used to store food for the first part of the voyage. For the entire two months at sea, the crew never bathed and instead cleaned themselves by swabbing with alcohol.

The use of the term "head" to refer to a ship's toilet dates to at least as early as 1708, when Woodes Rogers (English privateer and Governor of the Bahamas) used the word in his book, A Cruising Voyage Around the World.
How long and often can one shower for in a submarine? On a US nuclear sub, you take a shower every single day unless the evaporator is secured for a reason. In fact, the Chief of the Boat (COB) will usually demand you take a shower if you smell like sweat.
Any time the submarine sends a signal, it identifies its position, and loses the secrecy that is at the core of the crew's mission. There is only one washer and dryer on board, so clean clothes are a luxury. But submarines are famous for their good food, always topped off with a desert or two, including ice cream.
Enlisted women serve aboard four guided-missile submarines and one ballistic-missile submarine. There are 70 active submarines in the fleet.
In 2010, the Navy successfully implemented a comprehensive smoking ban aboard submarines.
Most submarines have a distillation apparatus that can take in seawater and produce fresh water. The distillation plant heats the seawater to water vapor, which removes the salts, and then cools the water vapor into a collecting tank of fresh water.
The cooling equipment of submarines consists of two separate systems, one for refrigeration proper, and the other for air-conditioning.
The consumption of alcohol on Royal Navy submarines is governed by Submarine General Orders. Personnel on duty may not consume alcohol while on board Royal Navy submarines and off-duty consumption is tightly regulated to ensure that individuals are fit for duty if required at short notice.
The one crew member who sustained fatal injuries was smoking in the smoking room at the time. It is perhaps surprising to think that there is actually space in a submarine for a smoking room. Indeed, it seems somewhat alarming that smoking is permitted given that there must be some (albeit small) increased fire risk.
Will I get seasick? Is it like being on a boat? Being on a submarine is very different to being on a boat. There is no rocking motion, as the submarine sits below the waves, and so people who get seasick on a boat will not do so on our submarine.
In real missions, the sleep time of the submarine crew varies in a wide range, extending from 5.75 h to 9 h, which may be influenced by many environmental factors [60].
A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world's oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.
Submarines can submerge more than 600 feet below the ocean's surface for up to four months at a time, constantly patrolling and working classified missions. You can't always see them, but they are always silently moving under the sea doing important work.
Underwater, submarines use acoustic signals (or SONAR) to communicate; in the air, airplanes use radio signals like cellular or WiFi. But neither of these signals can work across both water and air.
In the enclosed atmosphere of the submarine, these pollutants can build up and pose a health risk. Therefore, aerosol cans (such as hair spray, shave cream, spray deodorant) are not authorized to be brought on board. 9.
A submarine "day" lasts 18 hours and is split into three six-hour shifts. So a submariner may work for six hours and train, maintain equipment or sleep for 12 hours. Bunks are generally stacked three high. Space is at a premium in a submarine, and little of it is afforded to each sailor.
They watch movies, play video games, play cards, or just sit around and hang out. Sometimes they will get in a gym workout or run. Yes, submarines have gyms. Some modern-day subs are the length of two football fields and seven feet tall.
They showed us a tiny room with nine beds, but it actually sleeps more than a dozen through a process called hot racking, where three sailors working different shifts share two beds. Unfortunately, there's not enough room on a sub to give all 120 sailors onboard their own place to sleep.
A Navy shower is "the term used for a water-saving technique that was started in the Navy to help save precious freshwater aboard ships. The basic idea is to hop in the shower, get wet all over, turn off the water while soaping up, and then rinse clean.
