What to wear and bring to a sauna or cold plunge: a beginner's checklist
Nobody tells you the practical stuff until you show up unprepared. Here's exactly what to wear, what to pack, and what to leave at home for your first session.
For most studios and gyms, wear a swimsuit, bring two towels (one to sit on, one to dry off), a water bottle, and slides or sandals, and leave your jewelry and your phone in the locker. That covers 90% of first visits. The details change a little between a modern contrast studio, a traditional bathhouse, and a gym, and cold plunge adds a couple of items, but if you show up with a suit, towels, water, and sandals, you are ready. Below is the full checklist, plus the handful of things that quietly matter.
What should you wear?
It depends on the venue, so check before you go, but the defaults are simple.
At a studio or gym: a swimsuit is expected. Men usually wear trunks or briefs; women a one- or two-piece. Nothing loose enough to be a hazard in a plunge.
At a traditional bathhouse: varies more. Some have swimsuit-required hours and textile-free hours, and some are gender-separated. Many provide or sell a felt sauna hat, which protects your head from the heat and is worth using. Call or check the site so you are not surprised.
Materials matter a little: synthetic swimwear is fine. Skip anything metal, zippers, buckles, and underwire can get uncomfortably hot in a sauna, and cotton takes forever to dry after a plunge.
What should you bring?
The short packing list:
- Two towels. One to sit on in the sauna (always sit on a towel, it is the near-universal rule), one to dry off. Some venues provide them; bring your own if unsure.
- A water bottle. Heat dehydrates you, so drink before and after. This is the item beginners most often forget.
- Slides or sandals. Floors are wet and shared. Easy on, easy off.
- A hair tie if you have long hair, and flip-flop-friendly feet.
- A change of clothes for after, especially if you are plunging and heading out.
For cold plunge specifically, add: a warm layer for after (you will want it once the initial glow fades), and optionally neoprene booties or gloves if your hands and feet find the cold genuinely painful rather than just uncomfortable. Our first cold plunge and ice bath guide covers the temperature and timing side.
What should you leave at home or in the locker?
- Jewelry. Metal heats up in a sauna and can be lost in a plunge. Take it off.
- Your phone. Heat is bad for it, water is worse, and most venues treat the hot room as a screen-free space anyway. Lock it away.
- Heavy makeup and lotions. They run in the heat and can cloud a shared plunge. Come clean; most bathhouses require a shower first regardless.
- A big meal. Not a thing you bring, but worth saying: a sauna right after eating heavily is uncomfortable. Give it an hour.
The small etiquette that saves the awkward moment
A few unwritten rules that a checklist should include, because breaking them is how beginners get the look. Shower before you enter, with soap. Always sit on your towel. Keep your voice low and read the room before talking. Do not pour water on the sauna rocks without checking whether that is allowed and whether the room wants it. And open and close the door quickly, every second it is open, the room loses heat. Our first sauna session guide covers the etiquette in full, including how long to actually stay in.
The bottom line
Swimsuit, two towels, water, sandals, and a warm layer for after a plunge, that is the whole kit for a first visit. Leave the jewelry and phone in the locker, shower first, and sit on your towel. Get those right and you will look like a regular on day one. For what the heat and cold actually do once you are in, our sauna benefits explainer has the honest version.
