JD Wetherspoon outlet the Ledger Building in London's Docklands has taken first prize in the 2001 Cannon Hygiene Loo of the Year award.
The winner in Scotland was Wetherspoon's Clydesdale Inn at Lanark while another Wetherspoon outlet, the Coliseum in Abergavenny, took the Welsh award.
Awards director Richard Chisnell said: "The provision of outstanding loos, in terms of design, equipment and maintenance is clearly a number one priority for Wetherspoon."
The awards, aimed at highlighting standards in UK loos, are run in association with the English Tourism Council and the tourist boards in England and Wales.
Wetherspoon chairman Tim Martin said: "We are absolutely delighted with the awards. We spend a lot of time and money designing the toilets for our pubs and this has obviously been recognised by the judges.
"Pub toilets have not had the best image so it is very rewarding that a pub company won all three major prizes."
