A hand washing station has been set-up outside Pantibar.
Owner Rory O'Neill says the tap is properly plumbed into the mains.
The drag queen's shared an image on social media showing the soap and tap on the doors of the iconic pub.
Across the city, charities have been doing something similar.
Inner City Helping Homeless has had outreach teams encouraging rough sleepers to practice good hygeine.
Dublin Simon Community has also been setting up emergency cleaning stations amid the Covid-19 crisis.

People are urged to sing songs with a chorus of around 20-seconds while they clean up.
Experts say that's how long is needed to get a good scrub.
Examples include "Happy Birthday", Dolly Parton's "Jolene" and Queens "We Will Rock You".
