A squat toilet (or squatting toilet) is a toilet used by squatting, rather than sitting. This means that the posture for defecation and for female urination is to place one foot on each side of the toilet drain or hole and to squat over it. There are several types of squat toilets, but they all consist essentially of a toilet pan or bowl at floor level. Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet. The term "squat" refers only to the expected defecation posture and not any other aspects of toilet technology, such as whether it is water flushed or not.

Contents

Squat toilets are used all over the world, but are particularly common in some Asian and African nations, as well as in some Muslim countries. In many of those countries, anal cleansing with water is also the cultural norm and easier to perform than with toilets used in a sitting position. They are also occasionally found in some European and South American countries.

Squat toilets are regarded as traditional by many. In 1976, squatting toilets were said to be used by the majority of the world's population. [1] However, there is a general trend in many countries to move from squatting toilets to sitting toilets (particularly in urban areas) as the latter are often regarded as more modern. [2] [3]

Design

Squat toilets are arranged at floor level, which requires the individual to squat with bent knees. [4] In contrast to a pedestal or a sitting toilet, the opening of the drain pipe is located at the ground level.

Squatting slabs can be made of porcelain (ceramic), stainless steel, fibreglass, or in the case of low-cost versions in developing countries, with concrete, ferrocement, plastic, or wood covered with linoleum. [5] [6] Slabs can also be made of wood (timber), but need to be treated with preservatives, such as paint or linoleum, to prevent rotting and to enable thorough cleaning of the squatting slab. [6]

There are two design variations: one where the toilet is level with the ground, and the other where it is raised on a platform approximately 30 cm (1 ft). [7] The latter is easier to use for people who urinate while standing, but both types can be used for this purpose. There is also no difference for defecation or squatting urination.

Use

The user stands over the squat toilet facing the hood and pulls down (up in the case of skirts or dress) their trousers and underwear to the knees. The user then squats over the hole, as close to the front as possible, as excrement tends to fall onto the rear edge of the in-floor receptacle if the user squats too far back. [7]

Health, hygiene and maintenance

The standing surface of the squatting pan should be kept clean and dry in order to prevent disease transmission and to limit odors. [5]

Squat toilets are usually easier to clean than sitting toilets (pedestals), except that one has to bend down further if the squatting pan needs manual scrubbing. Squat toilets are properly cleaned using a mop in combination with a detergent solution. [8]

Health effects

The squatting defecation posture is more physiological, ideal and relaxed. [9] This is because it allows for better relaxation of the puborectalis muscle and hence straightening of the anorectal angle, and for faster, easier and more complete evacuation of stool. [10] [11] [9] The squatting position therefore prevents excessive straining, and hence protects against stretching of the nerves, such as the pudendal nerve. [11] [9] Damage of these nerves can lead to permanent problems with urinary, defecation and sexual function. The squatting position also increases intra-abdominal pressure. [10] The squatting position is often recommended as part of a range of measures to manage constipation and its sub-types, including obstructed defecation syndrome and dyssynergic defecation. Chronic, excessive straining during defecation, which is more likely to be needed in the sitting position, may be associated with the development of inflamed hemorrhoids or any of the spectrum of pelvic organ prolapse disorders, such as rectocele, rectal prolapse, etc.

However, according to some sources, excessive straining in the squatting position while defecating may increase the risk of severe hemorrhoids, or increase the tendency of prolapse of hemorrhoids, because of increased perineal descent and intra-abdominal pressure. [12] [13] Prolonged and repeated straining on a sitting toilet has the same effect. [13]

Society and culture

There are two different attitudes towards squat toilets, largely dependent on what users are used to, or whether the toilet is at a public or private place: Some people regard squat toilets as more hygienic compared to sitting toilets. They might be easier to clean and there is no skin contact with the surface of the toilet seat. [2] For that reason, some people perceive them as more hygienic, particularly for public toilets.

Some people regard sitting toilets as "more modern" than squat toilets. [2] Sitting toilets have a lower risk of soiling clothing or shoes, as urine is less likely to splash on bottom parts of trousers or shoes. Furthermore, sitting toilets are more convenient for people with disabilities and the elderly. [14]

A trend towards more sitting toilets in countries that were traditionally using squat toilets can be observed in some urban and more affluent areas, in areas with new buildings (as well as hotels and airports) or in tourist regions. [2]

Public toilets

Squat toilets are used in public toilets, rather than household toilets, because they are perceived by some as easier to clean and more hygienic, therefore potentially more appropriate for general public use. [2] [15] For instance, this is the case in parts of France, Italy, Greece, or the Balkans, where such toilets are somewhat common in public toilets (restrooms). [15]

Preferences by country or region

The following general statements can be made:

Europe

In Southern and Eastern Europe including parts of France, in Turkey, Greece, Italy, Albania, Balkans, and Russia they are common, especially in public toilets. [15] Squat pit latrine toilets are still present in many areas of Russia.

Squat toilets are generally non-existent in Northern and Western Europe. [2] France and Italy are an exception and have some squat toilets remaining in old buildings and public toilets because they used to be the norm there in the early 20th century. [19] In BMW Welt in Munich, the public restrooms have some stalls with squat toilets. There are also a few squat toilets at Stuttgart Airport.

China

Many areas in China have traditional squat toilets instead of sitting toilets, especially in public toilets. [20] Nevertheless, sitting toilets have increasingly become the norm in major urban areas and cities. [20] Sitting toilets are on the one hand associated with development and modernization, and on the other hand with reduced hygiene and possible transmission of diseases. [20]

Japan

Although in Japan it is believed that the squat toilet is traditional, the trend in Japan is to move away from squat toilets: According to Toto, one of Japan's major toilet manufacturers, the production of Western-style toilets increased rapidly since 1976. [21] In 2015, only 1% of all toilets produced by this company were squat toilets. [21]

Since the 1960s, the trend has been to replace squat toilets at schools and public places with sitting toilets. [21] This trend was thought to accelerate in the run-up to the 2020 Summer Olympics in Tokyo. [21]

Since the 1980s, high-tech sitting toilets are emerging that replace traditional squat toilets, especially in urban areas. One of those toilets with the brand name "Washlet" includes a "posterior wash" before wiping, and features heated toilet seats. However, many rural people have no experience with such high-tech toilets and need detailed instructions. [22] High-tech sitting toilets have also become commonplace in South Korea.

<span class="mw-page-title-main">Defecation</span> Expulsion of feces from the digestive tract

Defecation follows digestion, and is a necessary process by which organisms eliminate a solid, semisolid, or liquid waste material known as feces from the digestive tract via the anus or cloaca. The act has a variety of names ranging from the common, like pooping or crapping, to the technical, e.g. bowel movement, to the obscene (shitting), to the euphemistic, to the juvenile. The topic, usually avoided in polite company, can become the basis for some potty humor.

Elimination communication (EC) is a practice in which a caregiver uses timing, signals, cues, and intuition to address an infant's need to eliminate waste. Caregivers try to recognize and respond to babies' bodily needs and enable them to urinate and defecate in an appropriate place. Caregivers may use diapers (nappies) as a back-up in case of "misses" some or all of the time, or not at all. EC emphasizes communication between the caregiver and child, helping them both become more attuned to the child's innate rhythms and control of urination and defecation. The term "elimination communication" was inspired by traditional practices of diaperless baby care in less industrialized countries and hunter-gatherer cultures. Some practitioners of EC begin soon after birth, the optimum window being zero to four months in terms of helping the baby get in tune with their elimination needs, although it can be started with babies of any age. The practice can be done full-time, part-time, or just occasionally.

<span class="mw-page-title-main">Urination</span> Release of urine from the urinary bladder

Urination is the release of urine from the bladder to the outside of the body. Urine is released through the urethra and exits the penis or vulva through the urinary meatus in placental mammals, but is released through the cloaca in other vertebrates. It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, pissing, and euphemistically going number one. The process of urination is under voluntary control in healthy humans and other animals, but may occur as a reflex in infants, some elderly individuals, and those with neurological injury. It is normal for adult humans to urinate up to seven times during the day.

<span class="mw-page-title-main">Constipation</span> Infrequent or difficult bowel movements

Constipation is a bowel dysfunction that makes bowel movements infrequent or hard to pass. The stool is often hard and dry. Other symptoms may include abdominal pain, bloating, and feeling as if one has not completely passed the bowel movement. Complications from constipation may include hemorrhoids, anal fissure or fecal impaction. The normal frequency of bowel movements in adults is between three per day and three per week. Babies often have three to four bowel movements per day while young children typically have two to three per day.

<span class="mw-page-title-main">Hemorrhoid</span> Vascular structures in the anal canal

Hemorrhoids, also known as piles, are vascular structures in the anal canal. In their normal state, they are cushions that help with stool control. They become a disease when swollen or inflamed; the unqualified term hemorrhoid is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids often result in painless, bright red rectal bleeding when defecating. External hemorrhoids often result in pain and swelling in the area of the anus. If bleeding occurs, it is usually darker. Symptoms frequently get better after a few days. A skin tag may remain after the healing of an external hemorrhoid.

<span class="mw-page-title-main">Sanitation</span> Public health conditions related to clean water and proper excreta and sewage disposal

Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route. For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through adequate sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis, cholera, hepatitis, polio, schistosomiasis, and trachoma, to name just a few.

<span class="mw-page-title-main">Bidet</span> Plumbing fixture or type of sink intended for washing the genitalia and anus of the human body

A bidet is a bowl or receptacle designed to be sat upon in order to wash a person's genitalia, perineum, inner buttocks, and anus. The modern variety has a plumbed-in water supply and a drainage opening, and is thus a plumbing fixture subject to local hygiene regulations. The bidet is designed to promote personal hygiene and is used after defecation, and before and after sexual intercourse. It can also be used to wash feet, with or without filling it up with water. Some people even use bidets to bathe babies or pets. In several European countries, a bidet is now required by law to be present in every bathroom containing a toilet bowl. It was originally located in the bedroom, near the chamber-pot and the marital bed, but in modern times is located near the toilet bowl in the bathroom. Fixtures that combine a toilet seat with a washing facility include the electronic bidet.

<span class="mw-page-title-main">Latrine</span> Toilet or an even simpler facility that is used as a toilet within a sanitation system

A latrine is a toilet or an even simpler facility that is used as a toilet within a sanitation system. For example, it can be a communal trench in the earth in a camp to be used as emergency sanitation, a hole in the ground, or more advanced designs, including pour-flush systems.

<span class="mw-page-title-main">Rectal prolapse</span> Protrusion of the walls of the rectum outside the body

A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.

<span class="mw-page-title-main">Toilets in Japan</span>

Toilets in Japan are sometimes designed more elaborately than toilets commonly seen in other developed nations. European toilets occasionally have a separate bidet whilst Japan combines an electronic bidet with the toilet. The current state of the art for Western-style toilets in Japan is the bidet toilet, which as of March 2016 is installed in 81% of Japanese households. In Japan, these bidets are commonly called washlets, a brand name of Toto Ltd., and they may include many advanced features rarely seen outside of Asia. The basic feature set commonly found on washlets consists of anal hygiene, bidet washing, seat warming, and deodorization.

<span class="mw-page-title-main">Pit latrine</span> Toilet that collects human waste in a hole in the ground

A pit latrine, also known as pit toilet, is a type of toilet that collects human waste in a hole in the ground. Urine and feces enter the pit through a drop hole in the floor, which might be connected to a toilet seat or squatting pan for user comfort. Pit latrines can be built to function without water or they can have a water seal. When properly built and maintained, pit latrines can decrease the spread of disease by reducing the amount of human feces in the environment from open defecation. This decreases the transfer of pathogens between feces and food by flies. These pathogens are major causes of infectious diarrhea and intestinal worm infections. Infectious diarrhea resulted in about 700,000 deaths in children under five years old in 2011 and 250 million lost school days. Pit latrines are a low-cost method of separating feces from people.

Anal hygiene refers to practices that are performed on the anus to maintain personal hygiene, usually immediately or shortly after defecation. Anal cleansing may also occur while showering or bathing. Post-defecation cleansing is rarely discussed academically, partly due to the social taboo surrounding it. The scientific objective of post-defecation cleansing is to prevent exposure to pathogens.

<span class="mw-page-title-main">Toilet</span> Piece of hardware for the collection or disposal of human excreta

A toilet is a piece of sanitary hardware that collects human waste such as urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank. The waste is known as blackwater and the combined effluent, including other sources, is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.

<span class="mw-page-title-main">Defecation postures</span> Squatting or sitting to defecate

Humans mostly use one of two types of defecation postures to defecate: squatting and sitting. People use the squatting postures when using squat toilets or when defecating in the open in the absence of toilets. The sitting posture on the other hand is used in toilets that have a pedestal or "throne", where users generally lean forward or sit at 90 degrees to a toilet seat.

<span class="mw-page-title-main">Human anus</span> External opening of the rectum

In humans, the anus is the external opening of the rectum located inside the intergluteal cleft. Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus. These are the internal anal sphincter and the external anal sphincter, which are circular muscles that normally maintain constriction of the orifice and which relax as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. Above the anus is the perineum, which is also located beneath the vulva or scrotum.

<span class="mw-page-title-main">Bidet shower</span> Hand-held triggered nozzle

A bidet shower—also known as a handheld bidet, commode shower, toilet shower, health faucet, bum shower, jet spray, hand shower, Muslim shower, shatafa or bum gun—is a hand-held triggered nozzle that is placed near the toilet and delivers a spray of water used for anal cleansing and cleaning of the genitals after using the toilet for defecation and urination. The device is similar to that of a kitchen sink sprayer.

<span class="mw-page-title-main">Toilet (room)</span> Room for privately accessing a toilet, and often handwashing sink

A toilet is a small room used for privately accessing the sanitation fixture (toilet) for urination and defecation. Toilet rooms often include a sink (basin) with soap/handwash for handwashing, as this is important for personal hygiene. These rooms are typically referred to in North America as half-bathrooms in a private residence.

Solitary rectal ulcer syndrome or SRUS is a chronic disorder of the rectal mucosa. It commonly occurs with varying degrees of rectal prolapse. The condition is thought to be caused by different factors, such as long term constipation, straining during defecation, and dyssynergic defecation. Treatment is by normalization of bowel habits, biofeedback, and other conservative measures. In more severe cases various surgical procedures may be indicated. The condition is relatively rare, affecting approximately 1 in 100,000 people per year. It affects mainly adults aged 30–50. Females are affected slightly more often than males. The disorder can be confused clinically with rectal cancer or other conditions such as inflammatory bowel disease, even when a biopsy is done.

Obstructed defecation syndrome is a major cause of functional constipation, of which it is considered a subtype. It is characterized by difficult and/or incomplete emptying of the rectum with or without an actual reduction in the number of bowel movements per week. Normal definitions of functional constipation include infrequent bowel movements and hard stools. In contrast, ODS may occur with frequent bowel movements and even with soft stools, and the colonic transit time may be normal, but delayed in the rectum and sigmoid colon.

<span class="mw-page-title-main">Urine-diverting dry toilet</span> Dry toilet with separate collection of feces and urine without any flush water

A urine-diverting dry toilet (UDDT) is a type of dry toilet with urine diversion that can be used to provide safe, affordable sanitation in a variety of contexts worldwide. The separate collection of feces and urine without any flush water has many advantages, such as odor-free operation and pathogen reduction by drying. While dried feces and urine harvested from UDDTs can be and routinely are used in agriculture, many UDDT installations do not apply any sort of recovery scheme. The UDDT is an example of a technology that can be used to achieve a sustainable sanitation system. This dry excreta management system is an alternative to pit latrines and flush toilets, especially where water is scarce, a connection to a sewer system and centralized wastewater treatment plant is not feasible or desired, fertilizer and soil conditioner are needed for agriculture, or groundwater pollution should be minimized.
