Plan ahead for a fantastic voyage.

Congratulations–you’ve taken the plunge and booked a Lake Union Hot Tub Boat trip. Here’s everything you need to know to be ready, for an experience you’ll be talking about for years to come.

Arrival time

Plan to arrive 15 minutes early to change into your swimsuit. Grab free street parking (first-come, first-served) or arrive by ride-share for easy drop-off. You’ll be welcomed in by one of our team members, and if you haven’t already submitted a waiver, we’ll get your digital signature.

Safety and driving instruction

This is the moment–you’ll sink down into the stress-melting heat of your hot tub. As you soak, we’ll provide a quick but thorough overview of how the boat works, how to steer, and safety protocols.

Quick check-out

After soaking up Seattle, you’ll return to the dock and discard any rubbish from your trip. Retreat to our heated changing rooms before departing–and start thinking about your next voyage.

Restrooms and changing facilities

Before departure, you can use our restrooms and head to our heated, floating changing rooms. Take advantage of our secure storage space for anything that needs to stay behind–and dry.

Two hours of all-in exploration

It’s go time! As you’re taking in the sights, feel free to jump into the cool depths of Lake Union and refresh. Our boats’ ultra-stable design and easy in-out ladders are made for it. So you can fill your two hours with fun.

What You'll bring

  • Swimsuits
    Suits are a must. However, if you’re from out of town and didn’t pack a suit, you’re welcome to wear athletic shorts and a t-shirt, or another combination that can do the job of a bathing suit.
  • Beverages
    Beyond the drinking water we’ll provide, you can bring both alcoholic and non-alcoholic drinks to sip while you soak, though we do ask that you leave glass containers on shore for safety reasons. 
  • Snacks
    Pack your own bites and treats for the ride, keeping in mind that onboard storage is not waterproof, so you’ll need to plan accordingly.

How much does it cost?

$400 plus tax on weekdays and $450 plus tax on weekends.

How many people can rent one hot tub boat?

6 people – a person includes: a human at any age/life-stage (yes, children are people too). Per Coast Guard requirements, we can only have 6 people in the boat.

Can I rent more than one hot tub boat?

We love accommodating larger groups! We currently have the capacity to rent out three boats at the same time to accommodate up to 18 people. Just select 3 boats when you make your booking.

What is the cancellation policy?

Things happen and we get it! Full refunds are offered if you need to cancel 7 days prior to your trip. For less than 7 days prior to your trip, we do not offer refunds. We operate rain or shine. We monitor the weather and make day-of determinations regarding safety. Should we decide to cancel your trip due to weather-related reasons, we will reach out to you on the day of your booking and discuss options to reschedule.

What if the weather is bad?

Here at Lake Union Hot Tub Boats we believe that most days are perfect for hot tub boat rides! Our guests have great experiences no matter the weather – rain, sun, even the occasional snow flurry! However, safety is always our top priority and if we experience lightning storms or other weather conditions that we deem unsafe, we may have to cancel your trip. Should we need to cancel, we will contact you as soon as possible to discuss options to reschedule.

Is there dry storage on the hot tub boat?

No, there is not. The hot tub boat has two built-in storage areas for your drinks, snacks, speaker, etc. They offer easy access to anything you might need during your trip, but they do not offer protection from the water.  Our hot tub boats offer a full immersion experience.  You will definitely get wet! Whatever you bring on the boat with you will likely get wet! We do have 100% dry, secure storage in the changing area for you to safely leave your belongings on land.

What if I come back late?

We run a very tight schedule trying to prepare the boat for the next guests. If you bring the boat back later than 15 minutes you’ll be charged a $100 late fee plus an extra $100 for every 15 minutes after that. We do not have the ability to extend your rental time for any reason.

What if I damage the boat?

You will be responsible for any damage on a case-by-case basis. We offer damage protection that can be purchased when you make your reservation for $50 per trip.

What if something goes wrong during the cruise?

Our office number is posted on the boat and you can give us a call at any time. We can usually walk you through any issues but we also have a boat to provide as-needed support!

Is there free parking?

There is a gravel parking strip on N. Northlake Way and it is free back-angle parking, first come first serve. It can be tricky to find parking spots at times and if you are worried, feel free to rideshare or bike to our convenient location.

How warm is the water?

We heat the water to 104 degrees. It’s a wood-fired hot tub so you will have the ability to manually change the temperature if it gets too hot or not hot enough.

Are kids welcome?

Ages 2 and up are allowed. Anyone under the age of 18 must be accompanied by an adult. Anyone under age 12 must bring their own life vest.

Can I bring a paddleboard/kayak/inflatable flamingo/or anything else that floats and join a hot tub boat group on the lake?

No. Our reservations are for a maximum of 6 people. Each person signs a waiver. We will not allow a group to have more than 6 signed waivers. You cannot have other people join your group at any point during your reservation.

Are pets welcome?

We do not allow pets of any kind to join you in the hot tub boat.

How old do I need to be to rent a boat?

Anyone aged 18+ can rent a wood-fired hot tub boat.

Can I go in the hot tub boat if I am pregnant?

Soaking in a hot tub when pregnant is at the discretion of the pregnant person.

What wood do you use for the stove?

We use North Idaho Energy Logs. They are a warmer, greener, and cleaner source of wood fuel. North Idaho Energy Logs produce more heat from 100% natural recycled wood and cut emissions by more than 50%!

What to do if I get too hot?

Lots of options! You can close your fire so the water cools down in the tub. You can sit on the edge of the boat. Or you can jump in the lake!
