TL;DR: I did enjoy Badehuset in Christiania. I went there together with some people from the Shtandart ship.

It says on the entrance door that it's for Christianites - so we politely asked if it was space for us before we entered. My first reaction is that it's a cheap offer - it's an excellent offer for any backpacker that is desperately in need of a shower, as well as any Russian, Finn, Estonian or other sauna-lover that is desperately in need of a sauna, no matter the size of the wallet, anyone should afford 35 DKK for a sauna session. It's also a good offer for anyone else that would like a sauna session, even when not being desperate nor broke.
I even regret bringing my own towel - I had just done all the laundry on the ship and intended to leave the ship without any laundry bag to the borrowers, now I got this wet towel that first has to be dried and then stored somewhere and then washed. I would gladly have paid 10 DKK to borrow a towel if I had known about this offer. I also think it's very good that they have soap/shampoo in the shower - I think it's a bit of a hassle to bring your own, and I do have sort of a handicap when it comes to such things - the probability that I will either forget to bring my own or that I will forget to bring it home is high.

Another complementary thing was a reusable plastic cup. I didn't feel much thirsty, but considered that it was a good idea to drink some water after sweating a lot in the sauna.
That's all the photos I have - for one thing, one may be frowned upon for taking photos in Christiania at all, the people (and staff) in the bathhouse may mind if I take photos on the inside, and I also don't want to use the NSFW-tag on the post. If you do mind undressing in front others, the bathhouse is not the right place to go to. Clothes goes off, that's even explicitly written in the rules. Of course one may cover up a bit with a towel - but nobody does. It's not a big problem. For the first ten minutes I actively avoided staring at the ladies, after that it all felt just natural and relaxed.
Badehuset is no luxury spa - but it has the essentials; sinks, mirrors, showers with thermostat, showers with cold water, sauna, possibility to go outside for some fresh air, a cold-water pool for cooling down. It also has some toys and some small pools/buckets for the smallest children to bath and have some fun. There was no thermometer on the wall of the sauna, but it was hot enough. Nobody threw water on the oven to produce Löylya, but there was some facilities for it. The sauna was wood-fired, with the opening on the backside of the sauna so the staff could throw in more wood into the oven without having to enter the sauna. Staff was friendly.
Of course, this is Christiania - one shouldn't be surprised that people are drinking beer or smoking a joint in the staff area - there were also one or two customers firing up a joint, I observed one joint being lit up inside the bathhouse and one outside.
