Add recommended sauna related fields from 'leisure=sauna' Wikipage #1658

onnimonni · 2025-08-10T09:12:02Z

Description, Motivation & Context

I feel that sauna related tags are very well documented in the wiki.

But adding them for example in Go map!! is not very straightforward because these fields are not automatically shown.

I'm from Finland 🇫🇮 and we have ~5.5 million people and ~1.5 million saunas but only very few of them exist in OSM.

I hope that these changes will make it easier to contribute to OSM to let people enjoy sauna in more places 🧖‍♂️ 🧖‍♀️.

I'm new here and I'm not sure if I did everything correctly but I'm happy to learn 🙇

## Test-Documentation

### Preview links & Sidebar Screenshots

<!-- Use the preview to find examples, select the feature in question and **copy this link here**.
     Find examples of nodes/areas. Find examples with a lot of tags or very few tags. – Whatever helps to test this thoroughly.
     Add relevant **screenshots** of the sidebar of those examples. -->

<!-- FYI: What we will check:
     - Is the [icon](https://github.com/ideditor/schema-builder/blob/main/ICONS.md) well chosen.
     - Are the fields well-structured and have good labels.
     - Do the dropdowns (etc.) work well and show helpful data. -->

### Search

<!-- **Test the search** of your preset and share relevant **screenshots** here.
     - Test the preset name as search terms.
     - Also test the preset terms and aliases as search terms (if present). -->

### Info-`i`

<!-- **Test the info-i** for your fields and preset and share relevant **screenshots** here.
     The info needs to help mappers understand the preset and when to use it.

Welcome and thank you for helping improving the presets!

I just left a few comments while on the go and approved the preview-generation.

The thinks I want to look into more:

facility vs sauna-„room“ — some fields make sense in the facility. Others only in the „rool“
Unisex: we make a strong suggestion to use one tag over the others. We need to double check if there is agreement on this
Labels: I think we need to make them shorter…

will look into it more some other time.

data/fields/gender_segregated.json

+{
+    "key": "gender_segregated",
+    "type": "check",
+    "label": "Gender separated areas or timeslots"


I thing the label needs to be shorter to look well in the UI. We will see..

The UI should be yes/no/nil (unknown, default).
AFAIK we can have the value yes an a label that is more descriptive. That could help with getting the field label shorter.

Note to self: does the wiki talk about areas and timeslots? Do we map one sauna-room or the facility?; and what would the area be when it is a room? Or how would we map the room when the facility is meant?

Thanks a lot for your comments. I've understood that this tag could mean both area and timeslot.

At least here in Finland there are 3 very common types of saunas:

Unisex sauna (where everyone typically wears swimming wear)

Different sauna rooms for different sexes eg section for men and section for women.

One sauna room where they have separate timeslots for men and women.

I would understand that both 2 & 3 mean gender_segregated=yes but I'm happy to remove the timeslot interpretation.

But in order to make this PR smaller I can also remove the gender_segregated field and we can do it in a different PR.

Have you tested how that label looks in UI using PR build preview?

+            "dry": "Sauna without throwing water",


@ZeLonewolf Is "Sauna without throwing water" sounding good to native speaker?

it seems weird to me but I am neither sauna specialist nor English specialist

Yeah indeed this was not great choice of words. I will convert this to "Dry Sauna".

+            "hot": "Finnish Sauna over > 60°C",


base language of iD presets is EN-US and USA as far as I know is using some own temperature units

no idea how to deal with it, maybe it should be ignored?

+{
+    "key": "sauna:water",

+    "label": "Throwing water on the sauna stove"


is both and "dry": "Sauna without throwing water", option needed? Seems to be tagging double single piece of info

Well one doesn't normally throw water in steam sauna either.

Then there are normal hot saunas where throwing water is not allowed either.

It really depends.

This really makes a difference in the varm sauna.

ZeLonewolf · 2025-10-21T10:06:58Z

"Sauna without throwing water" sounds like gibberish. Wet sauna or dry sauna are the terms. https://musclelab.la/blogs/dry-sauna-vs-wet-sauna-what-s-the-difference-and-which-to-choose

per @ZeLonewolf "Sauna without throwing water" should be removed/changed unless other English experts disagree

onnimonni · 2025-11-23T17:21:36Z

The problem is that @ZeLonewolf comes from a totally different culture and yes internationally these 2 are the most common ones and they are the most boring saunas there are.

In Finland we have a separate word "löyly" which means the water thrown into the heater which then converts into a steam. The sauna is still very warm so in 80-100°C (176-212°F).

If you are interested you can watch this 4 minute video:
https://www.youtube.com/watch?v=_xMBZSBS5V8

So there's a major difference between a hot sauna and a sauna where throwing water is allowed.

Because of this I wouldn't really want to remove the water allowed option and this is the reason I added it there.

The link that @ZeLonewolf shared is content about saunas in the gyms or hotels. Not the ones we have in the north and in some parts of europe.

Koreans are nice that they have their own distinguished separate word (Hanjeungmak) for the sauna style that they have.

The finnish sauna means a hot sauna room and always being able to throw the water too. If this can somehow be described in a short field I would be very happy to modify this PR.

This style of saunas are the most common ones everywhere in the nordics and baltics. There are some saunas like these elsewhere but they are not as common.

The obvious solution for an English label is simply Finnish sauna. That's the title of the English-language wikipedia article for this concept.
