Tooting Bec Lido is an open-air fresh water swimming pool in South London. It is the largest swimming pool by surface area in the United Kingdom, being 100 yards (91.44 m) long and 33 yards (30.18 m) wide.
The Lido is on Tooting Bec Common between Tooting and Streatham. An original condition of construction was that it should be concealed from views across the common by a surrounding earth ramp. This ramp is now largely covered with bird-filled trees, except where it is breached by the new entrance.
The alternating bright red, yellow, and green doors of the changing cubicles seen above the turquoise water make the Lido a popular location for advertisement "shoots" and other filming. Brad Pitt's boxing "pool" scene in Snatch was filmed at the Lido.
The Lido is operated and maintained by the London Borough of Wandsworth.
The Lido is open to the general public from late May to the end of September each year. Tooting Bec Lido is home to the South London Swimming Club (SLSC) who have exclusive use of the Lido during the winter months, and members of the club can still swim all year around between 7am and 2pm. Yearly membership is currently (2015) priced at £125.
Tooting Bec Lido is one of Britain's oldest open air pools — it opened to the public on Saturday 28 July 1906 as the Tooting Bathing-Lake. Digging the lake had been proposed by the Reverend John Hendry Anderson, Rector of Tooting, as a project to provide work for unemployed local men. It holds one million gallons (4,500 m3) of water.
