What to expect on your first visit to Sonder Bathhouse

Walking into a bathhouse for the first time can feel a little uncertain. Where do you go first? What do you do? Is there an order? The honest answer: there isn't a wrong way to do it — but knowing what to expect makes that first session land properly.

Sonder is a 24/7 magnesium bathhouse in Bankstown — three mineral pools, a cedar sauna, a steam room, and the option of a massage. Most guests stay for 90 minutes. This guide walks you through what your visit will actually look like, from arrival to walking back out the door.

Before you arrive

Book your session online — sessions are limited and weekend evenings book out fast. You'll choose between four session types (Early Bird, Sonder Soak, Soak Essentials, or Soak + Massage), pick a date and time, and add any extras at checkout.

A few things to know before you walk in:

• Arrive 10–15 minutes early on your first visit. There's a short waiver to sign, a quick orientation, and you'll want time to change without rushing.
• Bring swimwear. One towel is included with every session, but if you'd like a robe or padlock for your locker, those are available to hire at reception.
• Eat lightly beforehand. A heavy meal right before a hot soak isn't the move. A small snack 30–60 minutes before is ideal.
• Hydrate. Drink water before you arrive. Sauna and hot pools dehydrate you faster than you'd expect.

Arrival and check-in

You'll come into reception, sign a one-time waiver (basic health and conduct questions), and a staff member will give you a quick walk-through of the space. We'll explain where the change rooms are, point out the pool temperatures, and mention anything specific about the facility you might want to know.

Change rooms are all-gender with private individual cubicles, all-gender toilets, and open showers. Have a quick rinse before entering the pools — it keeps the mineral water clean for everyone.

The order most regulars follow

There's no required sequence, but here's what most people settle into once they've been a few times. It's a framework, not a rule.

1. Start in the warm pool (28°C)

Ease in. This pool is body-warm and the longest of the three — it lets your body acclimatise, your shoulders drop, and the day start to slip away. Five to ten minutes is plenty.

2. Hot pool (40°C)

Now you're properly warming up. Magnesium pulls double duty here — easing muscle tension while your body works to regulate temperature. Stay 10–15 minutes max; this isn't a competition.

3. Sauna or steam room

Pick one (or both, over the course of the session). The cedar sauna is dry and intense; the steam room is wet and softer. Both push you a little further into the body's heat response. Limit each round to 10–12 minutes, even if you feel fine — heat tolerance builds with regular visits.

4. Cold plunge (9°C)

Yes, you're going in. Two minutes is plenty for a first time — most regulars don't go longer than three. The trick is exhaling slowly as you enter and keeping your breath calm. The cold is intense for the first 20 seconds, then it settles. You'll come out feeling startlingly alert and good.

5. Repeat or rest

A full session usually involves moving through this cycle two or three times. Many regulars take a break between cycles — sitting in the relaxation area, sipping tea, just being still. Listening to your body is the whole point.

What to skip on your first visit

There's no need to do everything in one go. If the cold plunge feels intimidating, skip it the first time. If the sauna feels too intense, sit it out. The point of a 90-minute session is that there's no rush — you can come back. (At 24/7, you really can come back. At 3am if you want.)

"Less is more. A relaxed 45 minutes done well beats 90 minutes of pushing yourself."

Etiquette — the social contract

Bathhouses work because everyone agrees to a few basic things. None of it is hard:

• Keep voices low. Sonder is a quiet space — phones on silent, conversations soft. If you want to chat with a friend, that's fine; just bring it down a notch.
• Rinse between sauna/steam and pools. You'll see signs and showers throughout.
• Phones are for selfies only. Never photograph other guests, even in the background.
• Move around. If a pool is full when you finish a sauna round, hop into a different one. Sessions flow better when nobody parks in one spot for the full 90 minutes.
• Don't wear cologne or perfume. In a small space with sauna heat, scents are intense for everyone else.

Aftercare — getting the most out of it

Here's the small secret that regular bathhouse-goers learn: skip the post-soak shower. The magnesium minerals are best left to absorb into your skin in the hour after your session. Rinse off at home later if you want, but go straight to dressing.

Drink water. You'll be thirstier than you expect. Most guests notice they sleep deeply that night, and that the next morning their muscles feel different — looser, less guarded. That's the magnesium doing what magnesium does.

The honest things first-time guests ask

"Will I be self-conscious?" Probably less than you think. Everyone there is doing the same thing as you, and the lighting is forgiving. Within ten minutes you'll forget about it.

"What if I don't like the cold?" Don't go in. The pools and sauna alone are a complete session. Cold plunging is a thing people work up to over multiple visits.

"Can I come alone?" Yes, and many guests prefer to. A solo session is a different experience from going with friends — both are valid.
