People tied yellow ribbons at the gates of Sutton's old school.
The teen's fundraising efforts attracted the support of many celebrities.
Comedian Ricky Gervais said he was a "true hero and inspiration to us all".
Broadcaster Phillip Schofield said: "My thoughts are with the family and friends of the remarkable Stephen Sutton. Would that we could all create such a legacy with such dignity."
Olympic gold medallist Ben Ainslie tweeted: "I was fortunate to hear #StephenSutton speak about his story. What an incredibly brave, determined and inspiring person he was #RIP."
Siobhan Dunn, chief executive of Teenage Cancer Trust which Sutton raised his money for,said: "“Stephen was an exceptional young man and ambassador for Teenage Cancer Trust. He will be remembered for his incredible positivity by all who met or connected with him.
"Stephen didn’t measure life in time, preferring instead to measure it by the difference someone makes. Stephen has made an enormous difference to Teenage Cancer Trust and the seven young people diagnosed with cancer every day who need our help.”
Deborah Alsina, from the charity Bowel Cancer UK, said "The passing of Stephen Sutton is an absolute tragedy when bowel cancer is curable, but early diagnosis is key.
"Stephen’s story struck a chord with the nation, putting teenage cancer and bowel cancer specifically firmly in the public eye.
"He has undoubtedly created greater awareness in the public and the clinical community that bowel cancer can affect younger people too and for this we owe him such gratitude.”
“In his memory and in memory of so many other young bowel cancer patients whose lives are needlessly lost, we will continue to tirelessly campaign for bowel cancer to be ruled out first not last within the diagnostic process.
"We will also continue to raise awareness that whilst younger people’s risk is thankfully low, you are in fact, Never too Young to develop bowel cancer. Our thoughts are with Stephen’s family and friends and we send them our very best wishes.”
