Status: de facto

This tag is used for a location where the public may bathe in common and there are visible signs and some kind of man-made facilities. E.g. an onsen, a hot spring, a hammam or a thermal bath. Bathers may or may not need to pay a fee, and there can be a separation by gender.

To map bathing places in nature where trashcans or other man-made facilities like toilets, showers, etc. does not exist use leisure=bathing_place instead.

How to map

To represent a stand-alone public bath, place a node or trace the bath building outline, then tag with amenity=public_bath.

Tags to use in combination

Hot springs such as those found in Japan (onsen) and Iceland have suggested tagging as detailed below.

Icelandic hot baths

In Iceland hot water from the ground is abundant due to geothermal activity, so the baths are often situated at the hot spring itself. Hot water from the springs are piped over to nearby settlements and used there. Natural hot springs can be mapped with natural=hot_spring
