I am wanting to know of public baths, bath houses, turkish baths etc... in London. 

1. What I am NOT looking for:
- gay saunas
- public swinning pools per se

2. What I AM specifically looking for:
- heated facilities (ie jacquzzi, sauna, cold plunge etc...)
- places where it is ok to go without a swimsuit, so it will usually
have certain days for men and certain days for women.

3. Places that I already know about (and hence dont need information about):
- Ironmonger's Row
- Porchester Spa

If you could provide me with information on places that meet these
three criteria it will be much appreciated. Serious tips if I end up
going there.

Well dude
there was York Hall which has been closed since last year but plans to
reopen in the Summer - whenever that means. It was a place to chill
out naked with other men of all ages, race, backgrounds, etc - and you
could give and get massages. A great exchange between the younger and
not so young.

Check the yorkhall group on Yahoo for more info.

There is a place in Canning Town which I dont know the name (if it has
one) and is tricky to explain how to get to - I can give you details
if you need them. Its men only most days, naked and not openly gay
although gay men do use it.

There's the Atherton sports centre in Romford which is ok but the
plunge was not too clean when I went twice.

Give me some feedback if you are still interested and I can give u more details.

The best place I have found so far for what you are looking for is
Germany. The Volksbad in Munich is great, Therme Erding also in Munich
is excellent. From what I can see most german cities have great
sauna's - check out

I'm off to Berlin next weekend and I can send you my research if you're interested.

Theres a hamman in Paris near the botanical gardens thats good as well.

Hope this is what you are after.

Would appreciate any info you have.
