Toilets are provided throughout Heathrow, in arrivals and departures, before and after security. Most include a unisex, wheelchair-accessible toilet. Occasionally the accessible toilet is located inside the men's and ladies' toilets.
Parents travelling with children of the opposite sex are welcome to use the unisex accessible toilets.
Showers are available in the No.1 Traveller Lounge in Terminal 3 departures (after security) – there is a charge for entry. Facilities may also be available to eligible passengers in the airlines' own lounges.
We have over 100 water fountains across Heathrow’s four terminals clearly sign-posted and located at most toilets where you are welcome to fill up your water bottles.
