What to Wear to a Spa Day: A Practical Guide to Packing and Dressing

Working out what to wear to a spa day is the one thing that trips up first-timers, and it is genuinely simple once you know the pattern: you arrive in comfy clothes, spend the day in a robe over swimwear, and change back to leave. That is the whole system. The details, what swimwear to bring, what footwear works, what to leave at home, are what turn a slightly awkward first visit into a relaxed one. This guide walks through exactly what to wear and pack so you can switch off from the moment you arrive.

The short answer

For most of a UK spa day you will live in a robe over swimwear. Spas keep the thermal areas, pools and relaxation rooms warm, and the robe is your default outfit as you move between them. Under it, wear swimwear if you plan to use the pool, sauna or steam room, which is almost everyone. So the real question of what to wear to a spa comes down to three things: what you arrive in, what swimwear you bring, and what goes on your feet.

What to wear on arrival

Wear something loose and easy to change out of. Joggers, leggings, a soft jumper or a simple dress all work, because within minutes of arriving you will swap them for a robe anyway. Avoid anything fussy with lots of layers or fiddly fastenings. The aim is comfort and a quick change, not a fashion statement, since barely anyone will see your arrival outfit once the robe goes on.

Swimwear: bring at least two

Swimwear is the single most important thing to pack, and it is worth bringing two sets. Spas mix pools, hydrotherapy features, hot tubs, saunas and steam rooms, so your first costume will be damp for much of the day. A dry spare means you are not pulling on a cold, wet swimsuit after lunch. Choose something you can genuinely relax in and walk around comfortably in, rather than a costume you spend the day adjusting. A one-piece or comfortable two-piece both work; pick whatever makes you feel at ease strolling between rooms.

Most spas provide a robe, and often flip flops, but you can usually bring your own robe if you prefer one you know is comfortable. Check your venue’s list when you book. For treatments such as a massage, the therapist will explain what to remove and will keep you covered with towels throughout, so there is no need to worry about that in advance.

Footwear that actually works

Many spas hand out flip flops, but they are one-size, thin and easily lost. A pair of your own flip flops or pool sliders is more comfortable and more hygienic on wet tiled floors. If your package includes a fitness class or a walk in the grounds, pack trainers too, and if there is an evening meal at a spa hotel, bring something suitable for the restaurant, as some have a dress code.

The full packing checklist

Beyond the outfit, a few extras make the day smoother:

• Two swimsuits, one to wear and a dry spare.
• Your own flip flops or sliders for the wet areas.
• A hair tie and a simple clip, so long hair is off your face for treatments and out of the pool.
• Glasses or spare contact lenses, since you will not want lenses in the steam room or pool.
• A waterproof or wet bag to protect your phone, headphones or a book from splashes.
• Loungewear or comfy clothes to change into after treatments if you are staying on into the evening.
• A smart outfit if your package includes dinner at a spa hotel with a dress code.

Leave valuables and heavy jewellery at home. Rings, watches and delicate necklaces do not mix with pools, saunas or oil-based treatments, and most spas ask you to remove them anyway.

Grooming: keep it simple

Arrive makeup-free where you can, because much of it will come off in the steam and water, and treatments are more effective on clean skin. Tie long hair back in a loose bun or ponytail and skip heavy styling products, which can transfer into the pool. If you have a facial booked, going in with bare skin lets the therapist work without removing a face of makeup first.

A relaxed first visit

Once you know the robe-over-swimwear rhythm, the rest falls into place. Pack the day before so you are not scrambling, and remember the point is to switch off, not to look polished.

Frequently asked questions

What should I wear to a spa day? For most of the day you will wear a robe over swimwear, which the spa usually provides the robe for. Arrive in loose, comfy clothes you can change out of quickly, bring swimwear for the pool, sauna and steam rooms, and pack your own flip flops. Under the robe, wear whatever makes you most comfortable walking around, which for most people is swimwear.

Do you wear swimwear under a spa robe? Yes, most people wear swimwear under the robe because you will be using the pool, hot tubs, sauna and steam rooms throughout the day. Bring two costumes so you have a dry one for the afternoon. For treatments like massage, the therapist will guide you on what to remove and keep you covered with towels the whole time.

What should I pack for my first spa day? Pack two swimsuits, your own flip flops or sliders, a hair tie, glasses or spare contact lenses, a waterproof bag for your phone, and loungewear to change into afterwards. Add a smart outfit if there is an evening meal with a dress code. Leave jewellery and valuables at home, as you cannot wear them in the pools or treatments.

Do spas provide robes and towels? Most UK spas provide a robe, towels and often flip flops as part of the day, but it is worth checking your venue’s list when you book, as some ask you to bring your own towel. Even where a robe is supplied, you can usually bring your own if you prefer a more comfortable one you know.

What should I not wear to a spa? Skip heavy jewellery, watches and anything valuable, which do not survive pools, saunas or oil treatments and are easily lost. Avoid arriving in fussy, multi-layered outfits, and go easy on makeup and styling products, which wash off in the steam and can transfer into the pool water.

Can I wear makeup to a spa day? It is best to arrive makeup-free or wear very little, because steam rooms, pools and facials will remove most of it anyway and treatments work better on clean skin. If you have a facial booked, bare skin lets the therapist start straight away rather than cleansing off a full face of makeup first.
