When I think of spa etiquette, I think of this friend who was visiting a Turkish spa in Budapest. (Read: Everyone was naked. This is Eastern Europe we’re talking about.) And no sooner had she stripped down and gotten comfy in the pool when she realized she had misplaced her locker key. She let her massage therapist know, and the therapist proceeded to take my completely naked friend by the hand and parade her around the entire spa—including the reception area—to help her find it. Needless to say, the language barrier was only the second most awkward part about the situation.

Unless you’re at a naked spa at a nudist compound, the likelihood of this happening in an American spa is slim to none. But this anecdote still serves a good point: the spa is no place to be shy.

So if you’re new to spas or just a generally reserved person, here are four spa etiquette tips to remember for your next spa day, and why you should feel empowered to throw modesty to the aromatherapy-infused wind.

So yeah, you may have to get naked.

Just how naked depends on what you’re having done. If it’s a massage, you can generally keep your underwear on. (And you’ll undress in private, getting under the sheets of the massage bed before the practitioner even comes into the room.) But for something a little more full-body, like a scrub or Vichy shower, etiquette norms suggest you may be a bit exposed. Disposable undergarments should be provided, though those often don’t provide full coverage.

Other circumstances call for no-shame-in-your-game levels of nudity. As one of our beauty editors discovered during a trip to King Spa & Sauna in Chicago, the Korean spa restricts clothing and swimsuits in its gender-segregated wet spas and pools. She was pretty nervous about it at first but found herself getting comfortable with it surprisingly quickly. Saunas traditionally embrace nakedness, too, though every spa is different.

And you might want to speak up.

Every body is different. And if it’s your first time working with a certain practitioner, they likely don’t know what feels good to you. Do not suffer in silence. As massage therapist Shannon Merten once told us, “I would rather my clients leave happy and satisfied than not, so if [the therapist] is doing something that is not enjoyable, a good ‘that’s a little too much pressure’ or ‘that area is too sensitive to be worked on’ should get you satisfying results.”

Speaking up is doubly important during skincare treatments. Is every chemical peel going to make you feel like you’re getting licked by puppies? No. Some discomfort can be expected, particularly during something more aggressive like a Jessner peel or microneedling. But if you’re in straight-up pain, that’s probably a sign that the treatment is too intense for your skin. This can often be remedied, especially during a facial or peel, as the aesthetician can start over with a lower-strength formula.

You’ll probably have to get personal.

Despite the inherently relaxing nature of spa treatments, they often come with a whole set of contraindications to particular medical conditions. It would be unsafe to not disclose pertinent medical history to your practitioner during the consultation process. Recent surgeries, the use of certain prescription medications, and various skin conditions all fall into this category. This is one of the few cases in life where oversharing isn’t a bad thing.

And you’ll definitely have to pee.

Whether it’s wine, herbal tea, or infused water, spas are all about the complimentary beverages. (And it’s good to stay hydrated, especially if you plan to hit a sauna or steam room.) When you’re in such a blissed-out state, it’s pretty common to not even notice you have to go until you’ve just tucked yourself under the sheets of the heated massage bed. Do not let modesty ruin what should be the best hour of your day. Just let the practitioner know that you need a bathroom break! They’ll happily oblige.
