A towel? Gym clothes? Nothing at all? The answer depends on the type of sauna you're visiting, where it's located, and the rules of the facility. The good news is that sauna etiquette is much simpler than you might think. Whether you're heading to a gym sauna, booking a luxury spa day, or trying an infrared sauna for the first time, here's everything you need to know about **what to wear in a sauna**, what to avoid, and how to feel comfortable during your session. ## What Should You Wear in a Sauna? For most public saunas in the United States, a clean swimsuit or securely wrapped towel is a practical choice. If you're using a private sauna, you may prefer a towel, lightweight clothing, or no clothing, depending on your comfort level. The most important rule is to follow the facility's dress code. Here's a quick guide: | Sauna Type | What to Wear | | ------------------------- | ------------------------------------------------------------- | | Gym sauna | Swimsuit or towel, according to gym rules | | Hotel or spa sauna | Swimsuit or towel wrap | | Infrared sauna | Swimsuit, towel, or loose lightweight clothing | | Private home sauna | Towel, swimsuit, or no clothing | | Traditional Finnish sauna | Often nude with a towel underneath, depending on the venue | | Mixed-gender sauna | Swimsuit or appropriate towel wrap unless otherwise specified | Regardless of your clothing choice, bringing a clean towel to sit on is good hygiene and common sauna etiquette. ## 1\. What to Wear in a Gym Sauna Gym saunas are among the most common types of saunas in the United States. Most facilities have rules about acceptable clothing, so check the signs or ask a staff member before entering. A simple swimsuit is usually a sensible option. For men, comfortable swim trunks work well. For women, a one-piece swimsuit or bikini may be appropriate, depending on facility rules. Some gyms also permit securely wrapped towels. Avoid entering in the workout clothes you've just worn during an intense exercise session. Sweaty leggings, compression shirts, and gym shorts can be uncomfortable in the heat, and wearing freshly cleaned clothing is more considerate of other guests. **Best option:** A clean swimsuit and a separate towel to sit on. ## 2\. What to Wear in an Infrared Sauna Infrared saunas operate differently from traditional saunas. Rather than primarily heating the surrounding air with a conventional heater, infrared systems use radiant energy to warm the body. These saunas commonly operate at lower air temperatures than traditional Finnish-style saunas. Because of this, some people find lightweight clothing comfortable. Suitable options may include a cotton tank top, loose shorts, a swimsuit, or a towel wrap. If you're using an infrared sauna at a wellness studio, follow its specific clothing requirements. For private sessions, a towel may be all you need. Avoid thick clothing, restrictive waistbands, and unnecessary layers that make you feel uncomfortable. Remember that infrared saunas still expose your body to significant heat, even if the room feels less intense than a traditional sauna. ## 3\. What to Wear in a Traditional Finnish Sauna Traditional Finnish sauna culture has its own etiquette. In Finland, sauna bathing without clothing is common, particularly in private and some single-sex settings. However, this doesn't mean every Finnish sauna requires nudity. Public facilities may have different rules, and some permit swimsuits or towel wraps. If you're visiting a traditional sauna for the first time, check the venue's guidance beforehand. A clean towel is particularly useful, as many facilities expect guests to place one between their bodies and the wooden benches. The main objective is to remain comfortable, respect cultural expectations, and follow the rules of the establishment. ## 4\. What Should Women Wear in a Sauna? Women have several practical options depending on the setting. A simple one-piece swimsuit is particularly convenient for shared gym and spa saunas. A bikini can also work where permitted, although designs without uncomfortable metal hardware may feel better in high temperatures. For private saunas, a lightweight towel wrap is another option. Avoid complicated swimwear with large decorative clasps, metal rings, or heavy embellishments. These can become uncomfortable as temperatures rise. If you prefer additional coverage, choose lightweight clothing approved by the facility. Ultimately, there's no special requirement for women beyond appropriate coverage, hygiene, comfort, and the venue's dress code. ## 5\. What Should Men Wear in a Sauna? For men visiting a public sauna, swim trunks are usually an easy choice. Choose a comfortable fit that allows you to sit and move freely. Board shorts may also be appropriate, although very long or heavy shorts can feel unnecessarily warm. If the facility permits towel wraps, a clean cotton towel secured around the waist is another option. For private saunas, clothing is a personal preference. Avoid wearing sweaty athletic shorts straight from a workout. Clean swimwear or a fresh towel generally makes for a more comfortable experience. ## 6\. Can You Wear Cotton Clothes in a Sauna? Yes, lightweight cotton clothing can be appropriate in some sauna environments. Cotton is soft and breathable, making loose shorts or a simple T-shirt potentially comfortable when additional coverage is preferred. However, cotton absorbs moisture and can become heavy as it gets wet. For this reason, towels and swimwear are often more practical than a complete outfit. If you choose to wear cotton clothing, make sure it's clean, lightweight, and permitted by the facility. Avoid thick sweatshirts, heavy pants, and multiple layers. ## 7\. Can You Wear a Swimsuit in a Sauna? Yes. Swimsuits are commonly worn in American gym and hotel saunas. However, rules vary across countries and facilities. Some traditional European sauna venues have designated textile-free areas where swimwear isn't permitted. Always check the dress code before entering. If wearing a swimsuit, choose one that feels comfortable and doesn't contain excessive metal details. It's also a good idea to rinse off after swimming before entering a sauna. A clean swimsuit is preferable to one heavily saturated with pool chemicals. ## What Should You Not Wear in a Sauna? Knowing what to avoid is just as important as choosing the right outfit. ### Heavy Workout Clothes Thick leggings, sweatpants, hoodies, and other heavy clothing can make the sauna unnecessarily uncomfortable. They may also interfere with your ability to recognize when you're becoming overheated. ### Metal Jewelry Necklaces, bracelets, rings, and watches can become hot in a traditional sauna. Remove them before entering to reduce discomfort and protect delicate accessories. ### Regular Shoes Outdoor shoes shouldn't be worn inside most sauna rooms. Some facilities permit clean sauna sandals, while others require bare feet. Follow the posted rules and use suitable footwear in shared changing and shower areas. ### Makeup and Heavy Skincare Products There's generally no need to wear makeup during a sauna session. Sweating can cause products to run or feel uncomfortable. A freshly washed face is often more comfortable. ### Phones and Electronics Leave your phone, smartwatch, and other electronics outside. High temperatures and humidity can damage devices. Keeping phones outside also respects other guests' privacy. ### Sauna Suits Plastic or rubberized sauna suits are designed to increase sweating, but additional sweat doesn't mean additional fat loss. They can increase heat stress and dehydration risk. Avoid using them inside a sauna. ## What Should You Bring to a Sauna? For a comfortable visit, pack a few basic essentials: - **Two clean towels:** One for sitting and another for drying off afterward. - **Swimsuit:** If required by the venue. - **Water bottle:** For hydration before and after your session. - **Clean sandals:** For changing areas where appropriate. - **Fresh clothes:** To change into afterward. - **A small toiletries bag:** Including shower essentials. You don't need expensive sauna accessories to enjoy the experience. A clean towel, appropriate clothing, and drinking water are the essentials. ## Sauna Etiquette: 7 Rules Beginners Should Know Beyond clothing, there are a few simple expectations worth remembering. **1\. Shower before entering.** This helps keep shared facilities clean. **2\. Sit on a towel.** Avoid placing sweaty skin directly against communal wooden benches. **3\. Respect the dress code.** Rules differ between gyms, spas, and traditional saunas. **4\. Keep conversations quiet.** Many people visit saunas to relax. **5\. Respect personal space.** Avoid sitting unnecessarily close to another guest when seats are available. **6\. Don't pour water on the heater without permission.** Some saunas aren't designed for this, and changing humidity affects everyone. **7\. Leave if you feel unwell.** Dizziness, nausea, weakness, and breathing discomfort are signs to stop. Following these rules makes the experience more pleasant for everyone. ## How Long Should You Stay in a Sauna? If you're new to sauna bathing, begin with a short session rather than trying to stay as long as possible. Around five minutes may be a reasonable starting point, depending on the temperature and your tolerance. Cleveland Clinic suggests keeping sessions to approximately 15–20 minutes at most, with beginners starting shorter. The most important consideration is how you feel. Leave immediately if you become dizzy, faint, nauseated, unusually weak, or uncomfortable. Drink water before and after your session, and avoid sauna use after consuming alcohol. People who are pregnant, have certain cardiovascular conditions, take medications affecting heat tolerance, or have other relevant health concerns should seek medical guidance before using a sauna. ## Frequently Asked Questions ### Do You Wear Underwear in a Sauna? You can wear clean underwear where the facility permits it, but a swimsuit or towel is generally more practical in a shared sauna. Avoid wearing the same underwear you've been exercising in. ### Can You Wear Leggings in a Sauna? Leggings aren't usually the most comfortable choice because they can become hot, restrictive, and uncomfortable when wet with sweat. Lightweight shorts or approved swimwear are generally preferable. ### Should You Wear Shoes in a Sauna? Most saunas have specific footwear rules. Clean sandals may be allowed, but regular outdoor shoes generally aren't appropriate. Check the facility's policy. ### Can You Go Into a Sauna Naked? Yes, where permitted. Nudity is common in private saunas and some traditional sauna cultures. However, many public facilities in the United States require appropriate coverage. ### Should You Wear a Towel in a Sauna? A towel is one of the most useful sauna essentials. You can wrap it around yourself for coverage where permitted, and a separate towel provides a clean barrier between you and the bench. ## Final Thoughts Deciding what to wear in a sauna doesn't need to be complicated. For most American gyms and spas, a clean swimsuit and towel are sensible choices. For a private sauna, you have more flexibility, while traditional Finnish saunas may follow different cultural expectations. The key is choosing something comfortable, keeping it clean, and respecting the rules of the facility. Once you've sorted out what to wear, you can focus on what really matters: enjoying a relaxing sauna experience.
