Spa Dress Code: What to Wear and What to Avoid at Hotel Spas

When you book a spa treatment at a hotel, the spa dress code, the unwritten rules about what to wear before, during, and after treatments. Also known as spa attire guidelines, it’s not about fancy clothes—it’s about comfort, cleanliness, and respect for the space and other guests. Most places don’t require you to show up in a designer robe, but showing up in jeans or a tank top will raise eyebrows. The truth? You’re expected to arrive ready to unwind, not to impress.

The hotel spa, a dedicated wellness area within a hotel offering treatments like massages, facials, and hydrotherapy. Also known as resort spa, it operates like a quiet sanctuary. That means your clothing choices matter. You’ll typically be given a robe, slippers, and a towel upon arrival. What you wear underneath depends on the treatment. For a massage, most people go bare under the robe—no need for underwear unless you’re uncomfortable. For facials or body wraps, disposable underwear is often provided. If you’re unsure, just ask. No one will judge you for being honest.

There’s a big difference between what’s allowed and what’s appropriate. Flip-flops are fine in the locker room, but not in the treatment area. Swimwear is okay if you’re heading to a wet area like a hot tub or steam room, but not for a massage. And please—leave the perfume, heavy lotions, and loud jewelry at home. These aren’t just etiquette rules; they’re about safety and comfort. A strong scent can ruin someone else’s relaxation. Jewelry can get caught in massage tables or scratch surfaces. Even your phone should stay off or on silent. This isn’t just about rules—it’s about creating a space where everyone feels calm.

Some resorts have gender-specific areas, so knowing the spa etiquette, the shared norms of behavior that ensure a peaceful, respectful experience for all guests. Also known as spa manners, it matters. Don’t assume you can wander into the men’s sauna if you’re a woman. Don’t bring kids into adult-only zones. Don’t talk loudly on your phone after your treatment. These aren’t nitpicks—they’re what keep the space peaceful. The best spa experiences happen when everyone follows the same quiet rhythm.

You’ll find plenty of advice online about what to wear, but the real answer is simple: show up prepared, stay humble, and follow the staff’s lead. Most hotels will send you a quick guide when you book. If not, call ahead. They’ll tell you exactly what to bring—and what to leave behind. The goal isn’t to look perfect. It’s to feel relaxed. And that starts with dressing for comfort, not for Instagram.

Below, you’ll find real stories and tips from guests who’ve been there—what worked, what didn’t, and how to avoid the common mistakes that turn a relaxing spa day into a stressful one. Whether you’re planning your first spa visit or you’ve been to a dozen, there’s something here to help you get it right.
