Public showers in Paris

Both exist. Each listing says which, and gives the amount where the source data or a contributor recorded it, so check at the door rather than treating the figure as a tariff.

Swimming halls, beaches and lidos, campsites, marinas and some sports grounds. They are rarely signposted as public showers, which is why they are worth having on a map instead of looking for on the day.

No. These are public-access facilities, nothing that needs a membership or a room key. Where a place expects you to be a customer, a campsite or a marina for instance, the listing says so.

Some campsites sell a shower to a passing traveller and some do not, and that is exactly the local knowledge the map is for. Where a contributor recorded that a site is customers-only or open to anyone, the listing says which.

Marinas are on the same map, with showers, toilets, laundry and pump-outs recorded per site where they are known. Tell the app you travel by boat and it stops showing places you cannot reach.

Often. Laundries are a category of their own in Fontavio, so you can look for both on one map, and campsites and marinas frequently have a machine beside the showers.

Seasonal facilities do. Beach and campsite showers often run only in summer, and where a place has known seasonal dates the listing shows them.

Each listing carries a badge for how recently a person confirmed it: verified means somebody checked it recently, unverified means nobody has, and might be outdated means it has been long enough to be worth a second look. One tap in the app confirms it for the next person, and one reports it if it has gone. A report about water safety is looked at before anything else.

Open the place in the free Fontavio app and tap directions to hand it to the maps app on your phone. On this page, each listing shows its address where one is known.

Just places assigned to Paris. A nearby town gets its own page once enough places in it have been mapped.
