Public loos in Market Deeping are to have a £45,000 refurbishment.
South Kesteven District Council is due to start work on the upgrade on Monday and finish by June 18.
The council says a single loo will remain open to the public on the Horsegate site, next to the town hall, for the duration of the work.
A council spokesman said: “All toilets are being refurbished including the ladies’, gentlemen’s and disabled facilities.
“The current toilet facilities require updating to make them more appealing to the public.
“The last deep clean at the site took place last autumn.
“Whilst this was successful and noticed by many, it was still thought the facilities required this new investment of £45,000.”
