On the London Underground network, new accessible toilets with baby changing facilities will be available at Battersea station and Nine Elms station when they open later in 2021 as part of the Northern Line Extension. The Cannon Street entrance at Bank will have toilet facilities. Transport for London (TfL) is also working with the Changing Places Consortium to pilot a ‘hybrid’ facility at Colindale station, which will vary slightly from a standard Changing Places toilet to make it available and accessible to a wider group.
When completed, 34 of the 41 Elizabeth Line stations will have toilet facilities, with a further 7 stations having toilet provision in an adjacent building. Where toilet facilities exist within stations, at least one will be fully accessible.A new accessible toilet was opened at Manor Park earlier this year, and accessible toilets will be installed at West Drayton and Southall stations by the end of this year. Permanent toilets will also be delivered at Taplow and Hayes & Harlington stations by the end of this year.
London Overground and TfL Rail toilet facilities are already free of charge. On London Underground, all toilet facilities are now free, following the removal of the coin operated mechanisms at co*ckfosters station earlier this year.
In total, TfL has around 100 stations on its network with toilet facilities, and these are published here: https://content.tfl.gov.uk/toilets-map.pdf
