Frequently Asked Questions
Electrical Requirements
Outdoor traditional saunas require a dedicated 240V circuit in order to accommodate the high heat output of the sauna heater. Please reference the product specification sheet to determine the specific requirements for your outdoor sauna.
Ventilation Requirements
Outdoor traditional saunas are equipped with an air vent in the ceiling. This air vent is designed to help circulate heat throughout the sauna during the heat up phase and to allow moisture to leave the sauna if you are adding humidity and using it as a steam sauna.
Maximum Temperature
The maximum operating temperature of the outdoor sauna is 170 degrees Fahrenheit. The normal operating range is 160-170 degrees Fahrenheit but will vary based on the outside temperature and other factors such as the placement location and exposure to the sun.
Outdoor Sauna Shipping
All outdoor saunas are shipped via truck freight with curbside and lift-gate delivery service unless otherwise specified. Our traditional saunas and steam saunas are shipped on a wooden pallet with removable bracing to protect the sauna boxes. Please contact us if you have special requirements for delivery. The trucking company will call you to schedule a delivery appointment.
Outdoor Sauna Warranty
All outdoor home saunas carry a 7-year structural warranty and 1-year parts warranty. All outdoor home sauna parts including electronic parts and the electric heater are guaranteed for 1-year against defects.
Outdoor Sauna Electrical
Outdoor traditional saunas come with a power cord that is attached to the heater. The power cord does not have a plug on the end. It is designed to be hard-wired into a junction box or you can put a plug on the end of the power cord. Please note that the power requirements differ by sauna model. Consult your outdoor sauna user manual for the specific power requirements.
Assembly and Installation
All outdoor sauna cabins are easily assembled by two adults. The typical assembly time is 1 hour. No special tools are required for the outdoor sauna to be assembled.
Returns and Cancellations
We allow returns of non-clearance outdoor saunas within 90 days of receipt of purchase if the home sauna kit is in new and resalable condition. The original and return shipping cost will be deducted from the refund. Outdoor home sauna kits that are returned with damage or not in new and resalable condition will incur a 15% inspection and restock fee.
Cleaning Your Outdoor Home Sauna
Your outdoor home sauna should be cleaned a minimum of every 3-4 months or more frequently depending on usage. To clean the interior of your home sauna, use a mixture of baking soda and water (3 teaspoons baking soda to 1 gallon of warm water). Using a clean towel, wipe down the interior of the sauna focusing on where sweat accumulates. Let the area dry with the sauna door open. Use a standard ammonia-based glass cleaner to clean the sauna doors and windows.
Outdoor Sauna Origin
SunRay outdoor traditional sauna cabins are constructed from Hemlock or Cedar wood which is imported from Canada. Our manufacturing facility is in China. Our distribution facility is in the United States. All warranty claims are handled by SunRay Saunas based in Richmond, VA.
Outdoor Sauna Specifications
On the outdoor sauna product page of our website, there is a specification sheet you can download. The specification sheet will provide you with all the details of the home sauna kit including the power requirements.
Sauna Heating Time
The average heating time for traditional outdoor home saunas ranges between 30-45 minutes depending on the outside temperature, outdoor location, and the size of the sauna.
Sauna Stones
Our outdoor traditional saunas come with heater stones that set on top of the heater elements. The heater stones are used to help radiate heat throughout the sauna and can be used to create humidity inside the sauna. DO NOT pour excess water on the heater stones as it will cause damage to the heater. To create humidity in the sauna, simply drizzle a small amount of water over the stones once they are hot.
Sauna Heater Placement
All outdoor traditional saunas have a cradle for the heater to sit it. DO NOT place the sauna heater directly on the floor as it could become a fire hazard. The outdoor sauna heater must be elevated off the floor to create air flow through the heating elements.
Sauna Lighting
All outdoor traditional saunas come with ambient dome lighting. Outdoor saunas with dome lighting can be connected to the heater so that the light turns off when the heater turns off. Alternatively, you can wire the lighting separately on its own switch. Consult your sauna heating wiring guide for instructions on how to wire your sauna light into the heater.
This outdoor sauna has been fantastic for both me and my family. The Harvia heater provides steady heat, and the interior is really comfortable. We’ve made it part of our weekend routine, and it’s become a highlight for us. It’s also a real conversation piece when friends come over.

I was looking for an outdoor sauna that could handle frequent use, and this model really delivers. The cedar wood smells amazing, and the contemporary design fits beautifully in my patio space.

I’ve been using the Seneca 3-Person Outdoor Sauna for three weeks now, and it’s been a game-changer for my recovery after workouts. The Harvia heater warms up quickly, and the heat feels consistent throughout the session. The design looks modern in my backyard, and it comfortably fits me and my wife. Highly recommend this if you want to bring spa-level relaxation home.
