Two replacement men's toilets are due to be installed today by an arson-hit block in Cromer.
North Norfolk District Council (NNDC), which owns the closure-threatened North Lodge Park conveniences, has arranged for the temporary installation and wants to thank the public-spirited people believed to have put out the fire.
The council has also pledged to prosecute the vandals responsible.
The blaze broke out in the men's toilets between 8pm and 8.15pm on Monday September 19 when toilet paper and a toilet roll holder were set alight.
John Rest, NNDC cabinet member for assets, said: 'This damage was caused by mindless vandalism. At a time when we want to make sure every penny counts we have to spend money, time and energy on repairs.
'If you helped put out the fire, saw anything suspicious or know who is responsible, please come forward. We have a policy to always prosecute and we will work with the police to bring the criminal or criminals to justice.'
Any witnesses are asked to call 01263 516054.
The women's toilet block was unharmed and remains in use.
North Norfolk District Council is currently consulting on plans to build new public toilets in the park as part of a plans to develop a new car park.
