A direct answer to spa dress code — what to wear arriving, what to wear during treatments, the robe-and-slipper experience, swimsuit policies, Korean spa nudity culture, and what to bring vs leave at home.

Depends on the spa and service. Day spas with separate-room treatments (massage, facials, body treatments): no swimsuit needed; the spa provides robes and you're under a sheet during the service. Day spas with shared pools, hot tubs, or saunas: swimsuit required for those areas. Korean spas: swimsuits are not permitted in bath areas (full nudity is the cultural norm); the mixed-gender lounge area provides unisex uniforms. Always-clothed facilities are rare — most spas have at least one area where partial or full undress is part of the experience. If you're unsure, ask at booking.

Do I need to wear a swimsuit?

What do I wear during the massage?

At most American spas: undressed to your comfort level under a sheet. You remove what you choose (some clients leave underwear on, some don't) in privacy after the therapist leaves the room. The therapist returns when you're under the sheet on the table. Only the area being worked on is exposed during the session — the rest stays covered. Korean spas and some European-style spas use different protocols — sometimes a disposable thong or robe is provided. The therapist should explain the specific protocol when you arrive.

Should I wear makeup?

No — most spa services are easier and produce better results without makeup. For facials especially, the esthetician will remove your makeup as part of the cleansing step anyway; arriving without it saves time. Most spas provide makeup removal wipes if you arrive with full makeup. For non-facial services (massage, body treatments, water access), light makeup is fine but expect it to come off during the experience. Many spa-goers arrive with bare skin and leave with naturally-glowing skin from the treatment — that's the actual goal.

What about jewelry and valuables?

Leave jewelry, watches, expensive bags, and large amounts of cash at home or in a hotel safe. Most spas have lockers for storing items during your visit, but theft does occasionally happen and the spa typically isn't liable for items left in lockers. Wearing valuables also creates friction during treatments — wedding rings get removed for massages, earrings for facials, necklaces for any face-down treatment. Easier to come jewelry-free. Wedding rings can stay on if you prefer; the therapist will work around them.

What's the dress code at a Korean spa?

Different from American spas. Bath areas (hot pools, cold pools, themed saunas) are gender-separated and require full nudity — swimsuits are not permitted. The cultural reasoning: swimsuit fabric carries soap residue, chlorine, and bacteria into the carefully-maintained bath water. The mixed-gender lounge area (where you eat, relax between baths, and access the common saunas) provides unisex cotton uniforms — typically shorts and a t-shirt. The bath rules feel surprising at first but the entire facility is structured around the nudity norm (no cameras, separated genders in bath areas, attentive cleaning of bath water). Once you adjust, it's a meaningfully different and often preferred experience.

What Should I Wear to a Spa in 2026?

For most American spas, wear **comfortable casual clothing arriving** (leggings or yoga pants, t-shirt, slip-on shoes) — the spa provides robes and slippers once you arrive. During treatments, you're typically undressed to your comfort level under a sheet (massage and body treatments), clothed except your face (facials), or in a swimsuit if you're using shared pool/sauna areas. Korean spas use different protocols (full nudity in gender-separated bath areas).

What to wear arriving

The arrival outfit should be:

**Comfortable and easy to change out of**: yoga pants, leggings, joggers; t-shirt or light sweater; slip-on shoes
**Light on layers**: you'll change into a robe shortly after arrival
**No tight waistbands or restrictive clothing**: if your service includes any time on a bed or in a chair before/after, you want comfortable clothing
**Easy-to-remove jewelry**: wedding rings can stay; everything else easier to leave home or in a locker

You'll change into a robe within 10-15 minutes of arrival at most spas. The arrival outfit just needs to get you in the door comfortably.

What happens at check-in

The standard American day-spa flow:

1. Check in at the front desk

Confirm your services, fill out any new-client paperwork, and get directed to the changing area. Some spas pre-fill paperwork by email; others handle it in person.

2. Change into the spa's robe and slippers

The locker rooms have private changing areas. Most spas provide a robe, slippers, and a locker key on a wristband or carabiner. You undress to whatever level you're comfortable with under the robe (some clients leave underwear on, some don't — varies by personal preference and what services you have booked).

3. Relax in the lounge area until your service

Most spas have a quiet lounge with tea, water, and sometimes light refreshments. Arrival 15-30 minutes before your first service is the standard recommendation — gives time to settle before the service starts.

4. Your therapist meets you at the lounge

When it's time for your service, the therapist comes to the lounge to collect you and walks you to the treatment room.

What to wear during specific services

The protocols vary by service:

Each service has its own dress code

Massage and body treatments — undressed to your comfort under a sheet; only the worked area exposed. Facials — clothed except your face; sometimes a wrap or smock provided. Water treatments — swimsuit required (or facility-provided). Hair and scalp treatments — clothed; cape provided. Nail services — clothed; comfortable seating provided. Korean spa bath areas — full nudity required.

**Massage and body treatments:**

Undressed to your comfort level under a sheet
The therapist leaves the room while you undress and get under the sheet
Only the worked area is exposed during the session — the rest stays covered
Underwear is optional; many leave them on, many don't

**Facials:**

Stay clothed; sometimes a wrap or smock over your top to protect from spills
Hair may be wrapped in a towel turban
Face cleansed of any makeup as the first step

**Water treatments (pools, hot tubs, soaking tubs):**

Swimsuit required at most American spas
Some facilities provide disposable or facility-owned swimsuits if needed
Korean spas: no swimsuits permitted in bath areas

**Sauna and steam rooms (American):**

Swimsuit or robe acceptable at most American spas
Some spas provide cotton wraps for sauna use

**Sauna and bath culture (Korean spa):**

Full nudity in gender-separated bath areas
Provided unisex uniforms in mixed-gender lounge

What to leave at home

For a smoother visit, leave behind:

**Expensive jewelry** — get in the way during treatments, easy to misplace
**Watches** — same; many spas request them removed for massages
**Makeup** — most services work better without it, and facials will remove it anyway
**Perfume or strong scent products** — many spas are scent-controlled environments
**Contact lenses** — if you can, wear glasses or come bare-eyed; saunas, steam rooms, and some treatments are easier without contacts
**Cell phone for ringing** — turn it to silent or leave in the locker; spa atmosphere is built around quiet

What to bring

A short list of useful items:

**Hair tie or headband** — for keeping hair out of your face during treatments
**Reading material** — for lounge time between services
**Sandals or slip-ons for the locker room** — useful if the spa's provided slippers don't fit
**Bottle of water** — most spas provide, but useful to have your own
**A change of underwear** — if you're swimming or doing water treatments

The Korean spa experience

Korean spas are a meaningfully different cultural experience:

**Bath areas are gender-separated and require full nudity** (no swimsuits permitted)
**The cultural reasoning**: swimsuits carry soap, chlorine, and bacteria into carefully-maintained bath water
**Mixed-gender lounge area** provides unisex cotton uniforms
**The full experience runs 4-8 hours typical** with cycles of hot soak, cold plunge, sauna, rest in lounge
**Bring nothing valuable**; lockers are provided
**Adjustment period**: most first-time visitors feel awkward for about 10 minutes, then adjust quickly

For most Americans, the first Korean spa visit is the most uncomfortable; subsequent visits are dramatically easier as the cultural norm sinks in. Many converts to Korean spa culture prefer it to American spa experiences after a few visits.

The bottom line

Wear comfortable casual clothing to a spa — leggings/yoga pants, t-shirt, slip-on shoes. The spa provides robes, slippers, and lockers. During treatments, undress to your comfort under a sheet (massage), stay clothed (facial), wear a swimsuit (water treatments), or follow facility-specific protocols (Korean spa nudity, European-style spa wraps). Leave jewelry, valuables, makeup, and strong scents at home. Bring a hair tie, reading material, and minimal essentials. The arrival outfit doesn't matter much — what matters is the dress-code expectations during the actual services.

Spa dress code is more flexible than first-timers expect. Comfortable arrival, robe-and-slipper transition, service-specific undress level. Once you've done it once, the routine becomes automatic — and the focus shifts to the actual experience rather than the logistics.
