Yes, it is a sauna! No, it is not a very large meat smoker.
We offer sauna sessions at the beach. Sessions last either 60 minutes or 75 minutes, noted in the session title when you sign up.
Anyone can book a spot during a session. There are limited spots per session, so guests reserve a spot online beforehand (as if you were signing up for a workout class).
During a session, each guest can cycle between the sauna and the cold water (or air) at their own pace.
Leave extra belongings outside of the sauna! We recommend leaving any and all items that are heat-sensitive outside of the sauna as the heat can impact their function including: jewelry, eyeglasses, phones, cameras, watches, etc.
Wash those sandy toes! Wash off sand and debris from the beach before entering the sauna. There is a foot washing station at the entrance.
Towels between all bums and benches! It is required that all guests sit on a towel inside the sauna.
Take your towel with you when you go for a dip! No saving seats in the sauna. Folks like to move around a bit during their session.
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 fellow saunamates.
Chat with your doc! For any health specific questions or guidance, consult your doctor. Bywater and its operators are not medical experts.
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 things. We recommend leaving all non-essential items at home.
Yes, but not private showers. The bathhouses have quick rinse outdoor showers available to rinse off before and after your session.
You are the boss of your cycling schedule! You can start and end on cold or hot.
For the hot, you can step out of the sauna at anytime and reap plenty of benefits. No matter your experience level, take a break after 15-20 consecutive minutes in the sauna to allow your core temperature to come down.
For the cold, any amount of cold water exposure complements sauna use and helps your body cool down quickly. If the cold water is not for you, time in the cool air is also beneficial.
With prior notice and when accompanied by a parent or guardian, yes! Please reach out directly to info@bywatersauna.com if one of your guests is under 18.
Add your name to the waitlist. When a spot opens up, every person signed up on the the wait list will be notified via email that a spot has opened up. Availability is first come, first serve.
The waitlist cannot accommodate multi-spot bookings -- Each person hoping to get in must sign up individually.
Cancel anytime up to 24 hours before the start of a session to receive a credit back to your Bywater account.
Bookings are non-refundable.
For drop-in reservations, late cancellations (less than 24 hours before a session) and no shows do not receive credit.
Members will be charged $20 per seat on their booking for late cancellations, and the full seat price per spot for no shows bookings.
Our lost and found bins are located at our Leschi location only (click the map under locations for exact directions). Left behind items at any of our locations will ultimately be stored at Leschi (may take up to 5 days after your session).
Unfortunately, we cannot confirm if a specific item is in the lost and found. Sadly, there are too many things in too many bags to dig through and reserve.
You are welcome to swing by our Leschi location during operating hours to look through our bins. For our most up to date hours at Leschi, please review our session schedule, filtering for the Leschi location. If we are hosting sessions, you can swing down and check the bins.
