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.
The showers on a submarine are set up much like the ones in your home, well kind of. They have hot and cold water access with a recirculation pump so that the water stays hot so that you can use it quickly and efficiently by minimising water usage.
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.
Answer: It dumps it into the ocean
Some of the garbage produced onboard, like paper, metal and food waste, is regularly dumped into the ocean by the U.S. Navy. Other waste is compressed, melted or shredded on board, and stored for disposal on shore.
Food for the crew is the bulkiest commodity in a submarine and becomes the limiting factor for patrol duration. Fresh food lasts about two weeks, then it is canned, dried, and frozen food for the rest of the patrol.
There are four mess specialists, or cooks, on a sub's crew, and typically only one is in the kitchen at any given time. The cook on duty often must prepare the entire meal, mainly because there is very little room for anyone else in the kitchen.
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.
There is also the etiquette of shower time -- three to five minutes being what these sailors constitute as being considerate of others since it is all about the "water run time" and the cycling out of dirty water for clean water these sailors must do.
Aboard fast-attack submarines, two bathrooms - each with four toilets and two urinals - serve 100 crew members. Crew chiefs and officers use another three baths. Designating one bath for a small number of women could disadvantage scores of men, while making them unisex raises other problems.
CO2 SCRUBBING
This is done chemically using soda lime (sodium hydroxide and calcium hydroxide) in devices called 'scrubbers'. The CO2 is trapped in the soda lime by a chemical reaction and removed from the air, ensuring a safe breathing atmosphere is maintained.
Ectopic pregnancies, which are not statistically rare, would create additional emergencies requiring immediate, extremely hazardous, evacuations, sometimes in midocean. Britain, Canada and the U.S. Navy do not put women on submarines primarily because of these irresolvable health risks and operational complications.
You are probably wondering why I would call this post such thing... Since Submarines remain submerged with a sealed atmosphere they rely on a chemical called Amine to remove the carbon dioxide. This chemical makes everything stink.
The fearless cookie-cutters have even disabled the most dangerous ocean creature of all—the nuclear submarine. They attacked exposed soft areas including electrical cables and rubber sonar domes.
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.
Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat.
Submarines are sometimes equipped with on-board devices that can connect to the internet with higher data rates, including via satellite, but these can only be used when submarines rise to the surface.
With a doctor on each Vanguard-class submarine and 24/7 gym facilities – including a rowing machine, treadmill and weights – the submariners can also ensure they stay healthy.
"Although alcohol is available on board Royal Navy ships and submarines, its consumption is extremely limited and the RN's promotion of healthy living, coupled with the professionalism of modern sailors, means that fewer sailors drink at sea than ever before," he added.
Because of the nature of the work and the limited space for onboard supplies, submarines typically have shorter deployments than surface ships. A typical submarine deployment is: 6 month deployment for a fast-attack or guided missile submarine (SSN/SSGN) 3 month patrol for a ballistic missile submarine (SSBN)
Modern submarines can stay underwater without coming to the surface for several days. This means crew members can breathe the same air for an unusually long time. Dr Aleksandra Sebastian and co-workers from Lund University, Sweden, have studied how the quality of air on submarines changes over eight days of submersion.

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.
Established reports and manufacturer's claims indicate that two (or perhaps more) submarines are capable of speeds exceeding 30 knots (56 km/h).
With deployments underwater typically running 90 days, life onboard a submarine is anything but normal. Cramped quarters are the norm, and sailors must have the right technical know-how as well as determination to spend months underwater at a time.
While ZipRecruiter is seeing annual salaries as high as $160,000 and as low as $22,500, the majority of Submarine salaries currently range between $67,500 (25th percentile) to $122,000 (75th percentile) with top earners (90th percentile) making $148,500 annually across the United States.
Submariners spend prolonged periods submerged without sunlight exposure and may benefit from vitamin D supplementation to maintain vitamin D status.
