The Grandby 300D outdoor infrared sauna is constructed of durable Canadian hemlock and comfortably seats 3 people.

Includes wide bench seating for maximum comfort, oxygen ionization system for purifying the air, recessed interior lighting, Bluetooth, cup holders, and more. The Grandby is easy to assemble and the natural Canadian hemlock wood will enhance any outdoor patio setting.


    "How is the sauna shipped? Can it fit through my bedroom doorway?"

    SunRay Saunas contain wooden panels that are pre-packaged in cardboard boxes and then placed on a wooden pallet to ensure the sauna arrives without damage. The cardboard boxes can be removed from the pallet and will fit through any door size 24” or greater.

    "How long does it take to assemble the sauna?"

    Most sauna models take about an hour to assemble. Two people are required. For more information on the assembly of the unit please see the assembly instructions.

    "Are there any special tools required to assemble the sauna?"

    No. The only tool you need to assemble the sauna is a Phillips head screwdriver or drill with a Phillips head-bit.

    "How do I clean the sauna and how frequently?"

    First, unplug the sauna and make sure it is cool before cleaning. To clean the wooden interior of your sauna mix 3 teaspoons of baking soda into a gallon of warm water. Use a towel to wipe down the interior with the baking soda and water mixture. Then wipe the sauna down with a wet towel and let dry. The glass in your sauna can be cleaned with glass cleaner. If you have an outdoor sauna, use a standard garden hose on a low/mist setting to wash out the interior. Make sure to leave the door open so the sauna can dry.

    The sauna should be cleaned every 6 months or at your discretion if you are using it regularly. Using a towel to sit on while in the sauna will capture a lot of the sweat and thereby reduce the frequency of cleaning the sauna.

    "How long does the model take to heat up?"

    Infrared saunas take roughly 20 minutes to heat up. Traditional saunas are a bit longer. Learn more

    Great Sauna!

    Delivery time was an issue but somewhat understandable due to COVID.
    The sauna arrived on a pallet in three large flat pack boxes. Initially assembly looked a little intimidating but actually it was pretty easy and the sauna was really well engineered and designed.
    We have used it several times now and everyone, especially my wife for whom this was a birthday present is really happy with it. My only comment would be that this would be a tight fit for 3 average size Americans and if you are considering a 2 person model definitely consider upgrading to the 3 person if you have room for it.

    Definitely recommended
