**Jack Sim Juek Wah**[a] (born 1957), also known as **Mr Toilet**, is a Singaporean entrepreneur and philanthropist who is the founder of the [World Toilet Organization](/source/World_Toilet_Organization) and [World Toilet Day](/source/World_Toilet_Day) initiative. He is also the founder of the [Restroom Association of Singapore](/source/Restroom_Association).

Sim started a number of successful business ventures before venturing into charitable work in his early forties. In 2001, he founded the World Toilet Organisation (WTO), an [international non-governmental organisation](/source/International_non-governmental_organization) for sanitation. After lobbying efforts with Singapore's [Ministry of Foreign Affairs](/source/Ministry_of_Foreign_Affairs_(Singapore)), the founding date of WTO was later adopted as World Toilet Day by the [United Nations](/source/United_Nations) in 2012. Sim's leadership of the WTO includes humanitarian, developmental, and advocacy work for sanitation.

Sim graduated with a [Master of Public Administration](/source/Master_of_Public_Administration) from the [Lee Kuan Yew School of Public Policy](/source/Lee_Kuan_Yew_School_of_Public_Policy) at the [National University of Singapore](/source/National_University_of_Singapore) in 2011. He is currently an adjunct associate professor at the university's business school.

## Early life and education

Sim was born the second of three children in 1957 to a grocery store assistant and a beautician, Tan Siam Kheng.[1][2] His family lived in an impoverished village in [Upper Serangoon](/source/Serangoon) without a plumbing system.[3][4][5] He studied at [Kim Keat Primary School](/source/Kim_Keat_Primary_School) and [Whitley Secondary School](/source/Whitley_Secondary_School), doing poorly academically and later failing his [O-level](/source/GCE_Ordinary_Level) secondary school examinations.[5] He attributes his academic difficulties to [attention-deficit hyperactivity disorder](/source/Attention_deficit_hyperactivity_disorder).[6] He later enrolled in the Vocational and Industrial Training Board (now the [Institute of Technical Education](/source/Institute_of_Technical_Education)), graduating with a certificate in hotel management.[5][7]

As an adult, he completed professional courses from the [University of Strathclyde](/source/University_of_Strathclyde) and [Harvard University](/source/Harvard_University).[8] In 2013, he received a [Masters of Public Administration](/source/Master_of_Public_Administration) degree from the [Lee Kuan Yew School of Public Policy](/source/Lee_Kuan_Yew_School_of_Public_Policy) at the [National University of Singapore](/source/National_University_of_Singapore).[9][10] He was thereafter appointed an adjunct associate professor at the NUS Business School and an honorary professor at [Shohbit University](/source/Shobhit_University_(Gangoh)) in Uttar Pradesh, India.[9][11] In 2022, he received an honorary [Doctor of the University](/source/Honorary_degree) degree from the University of Strathclyde.[12] He is a [fellow](/source/Fellow) of the [Singapore University of Social Sciences](/source/Singapore_University_of_Social_Sciences) and the Global Federation of Competitiveness Councils.[13][14]

## Business career

After leaving school, Sim worked as a construction site supervisor and salesperson at Diethelm (now DKSH) before starting a business at 24.[15] In 1982, he started Besco Building Supplies, which manufactured building materials.[16] By his early 40s, he had expanded his business portfolio to 15 companies, including a toilet cubicle manufacturer and a $115-million tiling factory.[10][17] He was also involved in real estate investments, at one point owning 15 properties,[18] and was a developer of the [Australian International School Singapore](/source/Australian_International_School_Singapore).[19] In the late 1990s, Sim watched a speech by then-Prime Minister Goh Chok Tong on the social significance of clean public toilets.[20] By the end of the [1997 Asian financial crisis](/source/1997_Asian_financial_crisis), he sold off a portion of his businesses and began to volunteer with the [Samaritans of Singapore](/source/Samaritans_of_Singapore).[21]

## World Toilet Organisation

In December 1998, he founded the Restroom Association of Singapore,[22] later launching a rating system for the cleanliness of public toilets in collaboration with the National Environmental Agency.[23][24]

On 19 November 2001, he founded the World Toilet Organization as an advocacy group for global sanitation. In his role as director of the WTO, Sim is a [lobbyist](/source/Lobbying) and coordinator for sanitation efforts,[25] organising an annual World Toilet Summit,[26][27] and contributing to administrative and policy changes in Brazil, China, India, and Singapore.[10][28][29] Sim also lobbied Singapore's Ministry of Foreign Affairs (MFA) to support establishing 19 November as World Toilet Day, which led to Singapore's first-ever tabled resolution at the United Nations in 2012, which succeeded with 120 co-sponsors.[30][31][32]

Sim raises funds for WTO through hosting the World Toilet Summits and philanthropic grants, including from the Lien Foundation and [Gates Foundation](/source/Bill_%26_Melinda_Gates_Foundation).[28][33] He uses [emotional branding](/source/Emotional_branding), humour, and celebrity endorsements to raise awareness of sanitation issues.[34][35] Under Sim's leadership, the WTO launched a series of World Toilet Colleges, which ran the world's first toilet-cleaning qualification programme,[36][37][38] and which currently provides sanitation training for people in the developing world.[39] He provided humanitarian aid for Turkey after the [2023 Turkey–Syria earthquakes](/source/2023_Turkey%E2%80%93Syria_earthquakes).[40]

In 2008, he was appointed to the [World Economic Forum](/source/World_Economic_Forum)'s Global Agenda Council for Water Security and the GAC for Social Entrepreneurship.[citation needed] He was appointed co-convenor of India’s Swachh Andhra Pradesh Initiative in 2015.[41]

For his work, Sim is also known as "Mr Toilet".[4][19] The eponymous documentary *[Mr. Toilet](/source/Mr._Toilet)* about Sim's activism premiered at North America's largest documentary festival, [Hot Docs Canadian International Documentary Festival](/source/Hot_Docs_Canadian_International_Documentary_Festival) on 27 April 2019.[42][43] Sim also worked with Singaporean director [Jack Neo](/source/Jack_Neo) in developing the 2013 film [*Everybody's Business*](/source/Everybody's_Business_(2013_film)).[44]

## Other social ventures

In the early 2010s, Sim ventured into social entrepreneurship as a means to diversify revenue for WTO.[28] Sim founded BOP Hub, a non-profit organisation targeting [bottom-of-pyramid](/source/Bottom_of_the_pyramid) individuals at the poorest global income margins in 2011,[45] developing a $10,000,000 building in [Ubi](/source/Kampong_Ubi).[46] In 2016, the organisation engaged in food relief efforts for migrant workers in Singapore,[47][48] and currently acts as a [startup accelerator](/source/Startup_accelerator) for social enterprises.[49]

He was also involved in bringing [Dialogue in the Dark](/source/Dialogue_in_the_Dark), a global disability social business, to Singapore.[50]

## Personal life

He lives in [Meyer Road](/source/30_Meyer_Road), [Katong](/source/Katong), Singapore.[51] His first marriage in 1989 ended in divorce after a year.[52] He remarried in 1990 and has two sons and two daughters with his current wife.[5][19][53] He identifies as having "no religion".[54]
