Popup Sauna FAQ | Bookings, Access & Your Visit

Question 1

How do I book a Popup Sauna?

Accepted Answer

Click “Book now”, choose your location, date and time, then complete payment. Book at least one hour in advance so the sauna has time to heat up.

Question 2

Can I cancel my booking?

Accepted Answer

If you cannot attend, cancellations and refunds are not available. You can request a move to an available slot up to 48 hours before your visit. If we cancel your visit, you can choose a replacement date or a refund.

Question 3

Can I reschedule my booking?

Accepted Answer

Yes, up to 48 hours before your visit, subject to availability. Email your booking number and preferred new date and time to support@popup-sauna.ch. The change is only valid once we confirm it.

Question 4

How do I book several hours or multiple saunas?

Accepted Answer

For a longer session, select your start and end times. The number of saunas determines how many cabins you rent at the same time. Check the date, time and number of saunas in the summary before paying.

Question 5

Where can I find availability and prices?

Accepted Answer

Select a location and date in the online booking calendar to see availability and prices. The price covers the entire sauna for up to 6 people. Check the location page for season dates.

Question 6

Can I extend my sauna session?

Accepted Answer

If the same sauna is available afterwards, you can book another hour online. For Lucerne, contact support@popup-sauna.ch, as sauna numbers are assigned automatically.

Question 7

When will I receive my access code?

Accepted Answer

Your personal 4-digit access code arrives by text message and email on the day of your visit. Your booking or confirmation number is not your access code.

Question 8

What if I have not received my access code?

Accepted Answer

On the day of your visit, check your text messages and spam folder. If the code is still missing, email support@popup-sauna.ch with your booking number, location and visit time. If your visit is today, put “DRINGEND / URGENT” in the subject line.

Question 9

Why does my code not open the door?

Accepted Answer

Your code only works during your exact booking time. Check the location and sauna number, enter the 4-digit access code and press #. Keep your code handy: the door locks automatically. If it still does not work, contact support.

Question 10

How do I adjust the temperature?

Accepted Answer

Open your booking confirmation or access-code email. Click “Buchung verwalten” (Manage booking) or “Meine Reservierung” (My reservation), then “Sauna”. You can adjust the temperature before and during your visit. The default preheating temperature is 80 °C.

Question 11

Why is the sauna not reaching my chosen temperature?

Accepted Answer

In Cham, Sursee and Walchwil, the maximum is 90 °C, even if 100 °C is offered online. Allow at least one hour for preheating. A previous session at a different temperature may affect the temperature when you arrive. If the sauna stays cold, contact support.

Question 12

What if my booking confirmation is missing or my details are wrong?

Accepted Answer

Check your spam folder first. If your confirmation is missing or your email address or phone number is wrong, contact support@popup-sauna.ch. Include your name, location, date and booking number, if available. If you have already paid, wait for us to check before booking again.

Question 13

How do I buy and receive a voucher?

Accepted Answer

Choose a voucher in our shop and pay online. You will receive a printable digital voucher by email, separately from your order confirmation. Check your spam folder if it has not arrived.

Question 14

Where do I enter my voucher code?

Accepted Answer

Enter the code from your voucher PDF in the payment section of the final booking step, after entering your contact details. The “Promocode” field at the beginning is for discount codes, not vouchers.

Question 15

What if my voucher code is not recognised?

Accepted Answer

Use the code from your voucher PDF in the payment step, rather than the order number or the “Promocode” field. If it still does not work, email your voucher and the error message to support@popup-sauna.ch.

Question 16

What if my voucher has expired?

Accepted Answer

Email your voucher code or voucher PDF to support@popup-sauna.ch. We will check whether it can be extended or reactivated.

Question 17

How do I pay with CSS Coins and find the QR code?

Accepted Answer

Go to popup-sauna.ch/css-coins, choose CHF 250 or CHF 500 in credit and click “Jetzt kaufen” (Buy now). Scan the QR code under “Bezahlen” (Pay) in the CSS Coin app and email a screenshot of the transaction to support@popup-sauna.ch. Your credit voucher will arrive by email within 24 hours.

Question 18

I paid with CSS Coins but have not received my credit voucher.

Accepted Answer

Check your spam folder and make sure you sent us the transaction screenshot. If more than 24 hours have passed since you sent it, follow up on your email to support@popup-sauna.ch. Please do not make the payment again.

Question 19

Is the sauna private, and how many people can use it?

Accepted Answer

You rent the entire sauna exclusively for your group of up to 6 people. For safety reasons, you must not use it alone. Larger groups need multiple saunas. Minors must be accompanied by a supervising adult.

Question 20

What should I bring, and do I need to wear swimwear?

Accepted Answer

Bring two large towels, swimwear, a bathrobe, flip-flops and drinks. Swimwear is optional inside the sauna; always place a large towel under your entire body. Swimwear is required outside the sauna and when swimming.

Question 21

Are there showers, toilets and changing facilities?

Accepted Answer

None of our locations has heated showers. The sauna has a small entrance area for changing. Check the relevant location page for information on toilets and other shower facilities.

Question 22

How are the saunas kept clean?

Accepted Answer

Our saunas are cleaned regularly. We also rely on your help to keep them clean between visits: please remove any obvious dirt, leaves and rubbish after your session. Report significant dirt or defects to support@popup-sauna.ch.

Question 23

What should I do if I left something in the sauna?

Accepted Answer

Check the grey lost-property box at the location first. If your item is not there or you cannot access the box, email support@popup-sauna.ch. Include the location, sauna, visit time and a detailed description of the item.

Question 24

How can I contact you if I have a problem on site?

Accepted Answer

There are no staff on site. Email support@popup-sauna.ch with your booking number, location, sauna number and a description of the problem, ideally with a photo. If it concerns your visit today, put “DRINGEND / URGENT” in the subject line.

Question 25

I received a suspicious message about my booking.

Accepted Answer

Do not click any links or enter personal or payment details. Forward the message to support@popup-sauna.ch so we can check it. You can report confirmed phishing messages as spam.
