Private floating sauna · Lake Union, Seattle

One Boat. One Group.
Completely Yours.

Seattle's private floating sauna, docked on Lake Union. Cedar dry sauna and steam sauna, cold plunge, wood-fired hot tub, and an upper-deck lounge — reserved only for your group.

3 hoursUp to 12 guestsAdults 18+ onlyFrom $600

Docked, calm, and all yours — no sailing, no schedule to chase. Banya Boat stays secured at the marina on Lake Union for your entire visit. Arrive, settle in, and the whole boat is yours for 3 full hours. The cold plunge is on board — there's no entering the lake or marina water.

The Experience

Heat. Cool down. Rest. Repeat.

Banya Boat combines traditional sauna culture, hot-and-cold therapy, and Lake Union views in one floating retreat. Come to recharge, recover, connect with friends, or simply escape the city for a while — nobody else is joining your reservation.

Cedar Dry Sauna

Traditional high-heat cedar sauna with a glowing Himalayan salt wall, reaching 185°F. Add water to the stones for short bursts of steam and deeper heat.

Steam Sauna

A softer, humid heat in the steam room — perfect for alternating with the dry sauna across your rounds.

Cold Plunge

Our designated on-board cold plunge, plus a cold bucket shower and outdoor showers to cool down gradually, at your own pace.

Wood-Fired Hot Tub

Soak on deck in the 700-gallon wood-fired hot tub with open views across Lake Union — day or under the lights at night.

Upper-Deck Lounge

Loungers, a fire table, and skyline views upstairs. Wrap up, breathe, and watch the lake between rounds.

Inside Lounge

Captain's chairs by panoramic windows, a nautical-chart ceiling, and backlit Seattle skyline art — the warm indoor space to rest between rounds.

Tea Station

Hot herbal tea and fresh cold water, on tap in the lounge. Pour a cup, wrap up, and watch the lake between rounds — tea is included with every session.

Changing Rooms

Two private changing rooms with benches, hooks, and lockers for your things — plus indoor and outdoor showers to rinse off before and after.

Cold Bucket Shower

Pull the chain for an instant cold cascade — the fastest cool-down on deck, alongside the outdoor showers.

Repeat the Cycle

When you feel ready, return to the sauna and repeat the cycle at your own pace. There is no competition and no need to push your limits.

6

Finish Warm & Relaxed

End with a shower, a soak in the wood-fired hot tub, or simply relax with tea and enjoy the view. Take your time and stay hydrated.

Adults 18+ only

Banya Boat is strictly 18+. No minors aboard, and no pets (except a qualified service animal where required by law).

The lake is not a cold plunge

Never swim, jump, dive, or enter Lake Union or marina water. Use only the on-board cold plunge, showers, and cold bucket.

A quiet marina, not a party boat

Keep voices and music respectful, walk carefully through the marina, and follow staff and marina instructions at all times.

Your health is your responsibility

Heat, steam, hot tub, and cold plunge carry real risks. Know your limits, stay hydrated, and stop immediately if you feel unwell.

Docked — but floating

The boat stays secured at the dock, yet decks and docks can move with wind, waves, and wakes, and surfaces get wet. Walk carefully and use handrails.

Bookings are final

All bookings and payments are non-refundable. Rescheduling is available, subject to availability. Rule violations can end a visit without a refund.

BANYA BOAT

2040 Westlake Ave N, Seattle, WA 98109 · (425) 748-4393 · BanyaBoat.com

Guest Agreement · Safety Rules · Assumption of Risk · Liability Waiver

Please read carefully. This agreement affects your legal rights.

Banya Boat is a dockside floating sauna and wellness facility located within a marina on Lake Union. Banya Boat remains secured at the dock during guest use and does not operate underway.

By entering or using Banya Boat, I acknowledge that I have read, understand, and agree to the following terms.

1. No Lake Entry — Zero Tolerance

The lake is not a cold plunge. Swimming, jumping, diving, plunging, or intentionally entering Lake Union from Banya Boat, any dock, float, walkway, or marina area is strictly prohibited.

Marina water may contain serious visible and hidden hazards, including:

  • Shore-power electrical systems and possible stray electrical current
  • Old pilings and submerged structures
  • Vessel traffic and propellers
  • Lines, anchors, debris, sharp objects, and underwater obstructions
  • Deep and cold water

Entering marina water may result in electric shock, electrocution, entanglement, collision, cold shock, drowning, catastrophic injury, or death.

Guests must use only the designated Banya Boat cold plunge, showers, cold bucket, hot tub, sauna, and steam facilities. Any intentional lake entry or attempt to jump or dive from Banya Boat or the marina may result in immediate removal without refund. If someone accidentally falls into the water, guests must immediately notify Banya Boat staff and follow emergency instructions.

2. Quiet Marina — Safe Conduct

Banya Boat is located within a quiet residential marina community. This is a wellness environment, not a party boat. Guests must:

  • Keep voices and music at respectful levels
  • Walk carefully and quietly through the marina
  • Avoid running, yelling, horseplay, fighting, or dangerous behavior
  • Never climb, sit, stand, or jump from railings, roofs, barriers, or restricted areas
  • Respect neighboring residents, vessels, docks, property, staff, and other guests
  • Follow all posted rules and instructions from Banya Boat staff and marina personnel

Unsafe, disruptive, threatening, destructive, excessively loud, or disrespectful conduct may result in immediate removal without refund.

3. Sauna, Steam, Hot Tub & Cold Plunge Risks

Banya Boat includes a high-temperature sauna, steam sauna, hot tub, cold plunge, showers, and rapid hot-to-cold exposure. I understand that these activities may involve risks including: burns, dehydration, overheating, dizziness, fainting, cold shock, blood-pressure changes, cardiovascular stress, loss of balance, falls, loss of consciousness, serious injury, and death.

I agree to use all facilities responsibly, remain hydrated, recognize my physical limits, and stop immediately if I feel unwell.

4. My Health Is My Responsibility

I am responsible for determining whether I am medically and physically able to participate. I will not participate if I know or reasonably believe that a medical condition, pregnancy, medication, heart or blood-pressure condition, seizure history, respiratory condition, illness, injury, impaired heat or cold tolerance, or other circumstance makes participation unsafe. If I am uncertain, I will consult a qualified medical professional before participating. Banya Boat staff are not responsible for determining my medical fitness.

5. Alcohol, Drugs & Impairment

Guests may not use Banya Boat facilities while dangerously impaired by alcohol, cannabis, illegal drugs, medications, or any substance that affects judgment, balance, coordination, consciousness, or the ability to follow safety instructions. Banya Boat may refuse entry or terminate participation when staff reasonably believes a guest is too impaired to participate safely. Removal for impairment or unsafe conduct is without refund.

6. Slips, Falls & Floating-Vessel Movement

I understand that Banya Boat is a floating structure secured within a marina. Although Banya Boat remains docked during guest use, the vessel and surrounding docks may move due to wind, waves, wakes from passing vessels, water conditions, weather, or movement of guests. Decks, docks, stairs, showers, sauna areas, hot-tub areas, and other surfaces may become wet or slippery. I agree to walk carefully, use handrails where available, and follow all posted safety instructions.

7. Adults Only

Banya Boat is strictly 18+. No person under 18 years of age is permitted aboard Banya Boat or may participate in any reservation or activity. Guests may be required to provide valid government-issued identification. Guests arriving with a minor may be denied entry or have the reservation terminated without refund.

8. No Pets or Animals

Pets and animals are not permitted aboard Banya Boat. Guests arriving with a prohibited animal may be denied entry or have the reservation terminated without refund. Nothing in this provision is intended to restrict an accommodation required by applicable law for a qualified service animal.

9. Personal Property

Guests are responsible for their own phones, jewelry, watches, clothing, electronics, and other personal belongings. Heat, steam, moisture, and water may damage personal property. To the fullest extent permitted by law, Banya Boat is not responsible for loss, theft, or damage to personal property.

10. Assumption of Risk

I voluntarily choose to participate in Banya Boat activities. I understand and knowingly assume the inherent and reasonably foreseeable risks associated with:

  • Sauna and steam exposure
  • Hot-tub and cold-plunge use
  • Rapid temperature changes
  • Wet and slippery surfaces
  • Stairs and docks
  • Floating structures and normal vessel movement
  • Proximity to Lake Union
  • Weather, waves, and wakes
  • Other activities described in this Agreement

I understand that serious injury or death is possible despite reasonable safety precautions.

11. Release & Waiver of Liability

To the fullest extent permitted by Washington law, I release and hold harmless Banya Boat, its owning and operating entities, owners, members, managers, employees, contractors, agents, representatives, and affiliates from claims, damages, losses, liabilities, or expenses arising from: my voluntary participation; risks I have knowingly assumed; my use or misuse of the facilities; my failure to follow this Agreement or safety instructions; and my intentional, reckless, or negligent conduct.

This release is intended to be as broad as legally permitted. Nothing in this Agreement waives any right or liability that cannot legally be waived under applicable law.

12. Damage & Rule Violations

I am responsible for damage or extraordinary cleaning costs caused by my intentional, reckless, or negligent conduct. Banya Boat may immediately terminate participation for: entering or attempting to enter marina water; unsafe use of facilities; dangerous horseplay; excessive noise or disruption; significant intoxication or impairment; fighting, harassment, or threatening behavior; property damage; entering restricted areas; or ignoring Banya Boat staff or marina instructions.

Termination for rule violations is non-refundable.

13. Cancellation & Rescheduling Policy

All Banya Boat bookings are non-refundable. All payments are final. If plans change, a reservation may be rescheduled to another available date and time. Rescheduling is subject to availability. No refund is provided for: no-shows; late arrival; voluntary early departure; personal inability to participate; removal for rule violations; or intoxication or unsafe conduct.

By completing a booking, I acknowledge and agree that all payments are final and non-refundable. Nothing in this policy limits any refund or remedy required by applicable law.

14. Emergencies

Guests must immediately notify Banya Boat staff of any injury, accidental water entry, medical emergency, fire, damaged equipment, electrical concern, or unsafe condition. Banya Boat personnel may contact emergency services and provide reasonable assistance when necessary.

Good to know before you come aboard

Can't find an answer? Reach us at info@banyaboat.com or (425) 748-4393.

What in the world is Banya Boat?

Banya Boat is a private floating sauna and wellness experience on Seattle's Lake Union. The entire space is reserved for your group, giving you time to enjoy traditional heat, cold therapy, relaxation, and waterfront views without sharing the facility with outside guests.

Does Banya Boat leave the dock?

No — and that's the point. Banya Boat is a stationary floating wellness facility docked at its moorage. It is not a chartered vessel and does not leave the marina during reservations, so you can arrive, settle in, and relax with no sailing schedule to chase.

Is Banya Boat rented privately?

Yes. Banya Boat is currently available for private group reservations only. Your group has exclusive use of the facility during your reserved time.

How many guests can come?

Private reservations are available for groups of up to 12 guests. Every session — weekday ($600) or weekend ($795) — includes up to 6 people, and additional guests may be added at $100 per guest up to the 12-person maximum. Banya Boat is adults only (18+).

What is included?

Your private experience includes access to:

  • Traditional cedar dry sauna
  • Steam sauna
  • Cold plunge
  • Wood-fired hot tub
  • Cold bucket shower
  • Outdoor showers
  • Two private changing rooms
  • Herbal tea station
  • Upper-deck lounge
  • Lake Union views
How long should we stay?

Private Sessions run a minimum of 3 hours — enough time to settle in, enjoy several rounds of heat and cold, relax between sessions, and experience the boat without feeling rushed. Additional hours can be added for the whole group at $200 per hour Monday–Thursday and $250 per hour Friday–Sunday. Short on time on a weekday? The Weekday Reset is a 2-hour session available Monday–Thursday daytime, with the same full-boat private access.

What sauna and cold plunge routine should we follow?

There is no single required routine, but many guests enjoy alternating between heat, cold, and rest: time in the dry sauna or steam room, followed by a cold plunge or cool shower, then a period of relaxation before beginning another round. Listen to your body and move at your own pace.

How hot is the dry sauna?

185 degrees Fahrenheit. Banya Boat features a traditional high-heat cedar sauna designed for an authentic banya-style experience. Guests can enjoy strong dry heat and add steam to the sauna stones for short bursts of humidity and deeper heat.

Is Banya Boat good for birthdays and private celebrations?

Yes. Because the entire boat is reserved for your group, Banya Boat works especially well for birthdays, small celebrations, wellness gatherings, couples, friends, and private group experiences. It gives everyone something to enjoy while keeping the atmosphere relaxed and personal.

Do guests need to sign a waiver?

Yes. Every guest participating in the Banya Boat experience is required to complete a liability waiver before using the facility. For group reservations, each participating guest should complete their own waiver before arrival. See the Liability Waiver section above — right after booking.

Are children allowed on Banya Boat?

Banya Boat is an adults-only (18+) experience, so your group can fully unwind. No guests under 18 are permitted aboard.

Can we swim in the lake or use it as a cold plunge?

No. The lake is not a cold plunge. Swimming, jumping, diving, or entering Lake Union or marina water from Banya Boat or the docks is strictly prohibited. Please use only the designated on-board cold plunge, showers, and cold bucket.

Where can I park?

Parking is available in the surrounding Lake Union area. We recommend arriving a little early to allow time to park, walk to the dock, and get settled before your reservation begins. Because parking availability can vary by day and time, rideshare is also a convenient option — especially for larger groups. Detailed arrival and parking instructions are provided with your booking confirmation.

What is the cancellation and rescheduling policy?

All Banya Boat bookings are non-refundable, and all payments are final. If your plans change, your reservation may be rescheduled to another available date and time, subject to availability.
