The artist Tracey Emin said she has been forced to "beg" to use shop toilets in Margate because of a lack of public facilities in her home town.
A number of toilets in Margate, Kent, have been closed while repair works are being carried out.
Thanet District Council has installed some portable loos, which will remain in place until late September.
But Ms Emin, who battled bladder cancer during lockdown and now has a urostomy bag, is calling for the public toilets across the town to be improved.
"For myself, who has a disability of having a urostomy bag, I often find myself begging and showing my disability card to use toilets in shops," she said.
"I can just about cope though because I live in Margate, but I wonder how it is for all the people who come to visit Margate, the children on the beach, the older people, people with disabilities."
The 59-year-old added that she was appalled to see human excrement on the beach and along the sea wall.
"Especially sad when there are a lot of public toilets that have just been left to go into disrepair," she said.
"As a citizen of Margate, and I am sure many small businesses will greatly benefit from the regeneration of public loos, the first ones being by the clock tower."
'Disgustingly dirty'
Last year, Emin spoke about the "disgustingly dirty" public toilets she had been forced to use in the town, because living with a urostomy bag means she needs to use the bathroom more frequently than before.
"I have to go to the loo every half hour. There tend not to be any around. If there are some, they're disgustingly dirty," she said.
The council said that while there are ongoing repairs to the facilities at Buenos Ayres and the Harbour Arm, the women's toilets at The Centre are currently closed due to fire damage.
Thanet District Council hopes the repairs to the public toilets will be completed ahead of the summer season.
"The number of public toilets in Margate has been impacted by ongoing repairs to the facilities at Buenos Ayres and the Harbour Arm," the council said.
"In addition, the women’s toilets at The Centre are currently closed as a result of fire damage.
"In response we have installed four temporary toilets at Marine Terrace, three unisex and one for disabled users, and a further two near Droit House.
"We anticipate that the repairs to the public toilets will be completed ahead of the peak summer season."
The council says while the women’s toilets at The Centre are temporarily closed, the nearest alternative public facilities are located at College Walk Shopping Mall.
"Additional seasonal temporary toilets will be in place at Botany Bay from the end of March," the council said.
"The temporary toilets will be opened and cleaned in line with our standard toilet management schedule.
"They will all remain in place until late-September."
