Things to know before you go.
We offer sessions throughout the week that are open to the public. There are limited spots during each session. To make sure you have a spot, we suggest that you reserve a spot online beforehand (as if you were signing up for a workout class). Click the 'Book' links on our website to do so.
During a session, the sauna is open to you and the other folks that reserved a spot. Each guest can cycle between the sauna and the cold water (or air) at your own pace.
The drop-in rate is $35 for a 60 minute session and $40 for a 75 minutes session.
Yes! Each of our locations have public restrooms, but you can save time by arriving in your bathing suit.
Wash those sandy toes! Wash the sand and debris from the beach before entering the sauna. There is a foot washing station at the entrance of the sauna.
Towels between all bums and benches! It is required that all guests sit on a towel inside the sauna.
Mind the door! Close it quickly behind you to minimize escaping heat.
Consider the group when steaming the space. Let the folks in the barrel know before pouring water on the rocks in the sauna. Ladle the water on gently, like gravy, not soup.
Actually, consider the group always! Bywater is a shared space. Respect your sauna mates.
Bywater reserves the right to refuse service to any guest that violates these rules.
We have shelves and hooks available outside the sauna for guests to put their things. We recommend leaving all non-essential items at home.
You are the boss of your cycling schedule! You can step out anytime and reap plenty of benefits. No matter your experience level, we recommend taking a break after 20 consecutive minutes in the sauna to allow your core temperature to come down.
If you feel dizzy or lightheaded at any point, hop out and let us know.
Any amount of cold water exposure can complement your sauna experience. If the cold water is not for you, time in the cool air is also beneficial. If you have more specific questions and goals, ask the Bywater operator and they will nerd out all about it!
When a spot opens up, we automatically pull from the waitlist and add the guest to the session. This can occur any time before a session's start time. If you would no longer able to attend a session that you are waitlisted for, please remove yourself.
Bookings can be cancelled without penalty anytime before 12 hours in advance of the start of a session. If you purchased as a drop-in, you will automatically receive a credit back to your Bywater account. If you prefer a refund to your method of payment, please email us at info@bywatersauna.com
For late cancellations, those that occur less than 12 hours before a session, and no shows, there are penalties. If a drop-in booking, no refunded credit. If a membership booking, there is a charge of $20.
