Steam Room and Sauna on Marina

We are new to Oceania and I have a question: are Steam Room and Sauna visits are free or Oceania is charging for use of sauna? How much?

Thanks,

Mike

Same question for the small ships?

Really more interested in what they are like, not cost.

On all of the ships, the Sauna and Steam Rooms are free and located adjacent to the gymnasium locker/changing Rooms.

One set for Women and a separate set for Men.

I've only been on Insignia, but there was just a steam room...no sauna. The woman's was very nice and good sized....hot steam but no aroma. There were also 2 good sized showers, lockers, benches, towels, a restroom and a cooler with water and Gatorade beverages. All free for everyone's use and right between the gym and spa.

Correct me if I'm wrong but I believe the O-ships (Riviera and Marina) have both steam rooms and saunas while the R-ships only have steam rooms.

That is correct.
