The desperate dash to find a public loo on Britain's high streets could be eased with a plan to pay businesses to open their toilets to non-customers.
Public toilets are being closed due to funding pressures
Pubs and restaurants across the UK will be encouraged to open their toilets in exchange for as much as £600 a year.
The government is expected to urge local councils to adopt the scheme in order to address a national shortage.
But the British Toilet Association said the idea is only part of the answer to a problem plaguing the nation.
Richard Chisnell, director of the association, said the review of the public toilet situation by the Department for Communities and Local Government is supposed to be released early next month.
Mr Chisnell said he worries that the DCLG is not being forceful enough when it comes to pushing local authorities to fulfil a "moral duty" to offer clean, accessible toilets to members of the public.
"My feeling is that this is a very watered-down attempt to encourage local authorities to act," he said of the government's planned guide.
The scheme to pay local businesses builds on the success of Twickenham, where 66 businesses agreed to display window stickers offering their toilets to non-customers in exchange for £600 a year from Richmond upon Thames council.
Mr Chisnell said that plan worked largely because it was well-marketed and includes finger point signs throughout the community to help the public find the participating restaurants and pubs.
But, he added, the community restaurant scheme should only be "one important tool in the public toilet armoury".
Well-known chains including Pizza Express, KFC and the Slug and Lettuce pub joined Twickenham's Community Toilet Scheme.
Westminster council is using mobile technology to point people to toilets
The DCLG will express "growing public concern" at the declining number and standard of public conveniences next month and urge other councils to follow suit.
A DCLG spokeswoman said: "Far from dictating how councils should provide more public conveniences, we hope to share the best examples of what is already being done, so that other councils can consider what could work best in their area."
Last November, Westminster City Council launched the "SatLav" mobile phone service which alerts people to the nearest public toilets.
Texting the word "toilet" to the number 80097 prompts a quick-response text with details of the nearest facilities and their opening times.
Mr Chisnell said the lack of public facilities is damaging to commerce, tourism and the country's reputation and needs to be addressed well in advance of London hosting the 2012 Olympic Games.
"Public toilets are vitally important to everyone."
