Shipping & Delivery

Cost Free to the contiguous US. No PO boxes. Rural or remote delivery addresses may carry a freight surcharge — call us to check yours before you order.
Method LTL freight truck.
Transit time 7–20 business days once it ships
Delivery type Curbside

What curbside delivery means

The freight driver brings the crate to the curb at the end of your driveway, and that is where it stops. Drivers do not take freight into a garage, a backyard, or around the side of a house. This is a heavy crated shipment, so work out how you will move it from the curb before it arrives. Call us and we will get you the crate weight for your model.

Three things you need to do

  1. Be there. Someone has to be present to receive and sign for the delivery. If nobody is there, the freight company charges a redelivery fee.
  2. Inspect before you sign. Check the crate for damage in front of the driver and note anything you find on the delivery receipt before you sign. Photograph it.
  3. Report hidden damage within 3 business days. Damage you could not see at delivery has to be reported inside that window, with photographs, or the claim may not be accepted.

Want a hand getting it off the truck? A second person can be arranged to help unload for an additional charge. Call us before you order and we will get you that cost.

Before your first session

Assembly is required. The heater runs on a dedicated 220–240V circuit and must be wired in by a licensed electrician before first use. Book that work for the week of delivery so the sauna is not sitting unused while you wait on an electrician.

Notify me when back in stock

Delivery times vary by product: Standard items typically arrive in 3–7 business days. Our handcrafted, made-to-order signature structures require a longer production lead time and typically ship via specialized freight in 4–6 weeks. All freight deliveries include a scheduled delivery appointment—see our Shipping Policy for full details.

Description

The Owner's Insights on the ALEKO Thermowood 5 Person Sauna

This is the outdoor sauna kit I suggest when a host wants a traditional wet/dry sauna that seats a whole group. It's a thermowood cabin for up to 5 adults, with a 6 kW Harvia KIP heater, a tempered glass door and an asphalt shingle roof.

What I like most is how simple it is to run. Your heater has two dials, one for temperature and one for on/off with a timer. There's no app or wall panel to explain in your house manual. Your guests can keep it dry and hot, or ladle water over the stones for a burst of steam.

My honest note: the kit price isn't the whole budget. You'll need a licensed electrician to run a dedicated 240V, 30-amp circuit, and a level base to set it on. If you sleep more than 5, the 8 person Canadian Hemlock sauna is the better fit.

Why You'll Love the ALEKO Thermowood 5 Person Sauna

  • 6 kW Harvia KIP heater, UL certified. A Finnish-made heater with simple dials. UL certification matters on anything guests use when you're not there.
  • Automatic 60-minute shut-off. If a guest forgets to switch it off, the heater turns itself off within the hour.
  • Thermowood walls. The heat-treated wood resists rot and warping and holds heat well, so your cabin stays solid through wet seasons.
  • Wet or dry sessions. Your guests pour water over 35 lb of included stones for steam, or keep it dry at up to 194°F.
  • Weather-resistant roof, tempered glass door. Asphalt roofing protects your cabin outdoors, and the door is tempered glass.
  • Ready for the first session. Bucket, ladle, sand timer, thermo-hygrometer, LED light and built-in vents all come in the kit.

Not sure your property has the power or the space? Call us at 1-800-914-0074 or email sales@optimaloutdooroasis.com. Tell us where you want it, and we'll help you check the electrical and the base before you order.

Why You Should Consider an ALEKO Sauna

ALEKO is a Kent, Washington company that sells saunas, cold plunges, hot tubs and other outdoor living products across the US. On this model, ALEKO pairs its own cabin with a heater from Harvia, a Finnish heater maker. You get a 1-year limited warranty, free shipping to the contiguous US, and an ALEKO parts and support team behind it.

What Electrical Hookup Does This Outdoor Electric Sauna Need?

This is an outdoor electric sauna, so plan the power first. ALEKO's manual for the Harvia KIP heater calls for a 240V single-phase circuit on a 30-amp double-pole breaker, wired with 10/2 copper wire. If the sauna sits more than 30 feet from your panel, the manual recommends 8/2 wire for the 6 kW heater. It also says not to use a GFCI on this heater.

That's a job for a licensed electrician, so get the quote before you order. Wondering about running costs? At full output, a 6 kW heater uses up to 6 kWh in an hour. Multiply 6 by your electric rate per kWh, and you have the most an hour of heating can cost you.

Is Thermowood Good for an Outdoor Sauna?

Thermowood is wood that has been heat-treated. ALEKO uses it on this cabin because it resists rot and warping in changing weather, and it has high thermal insulation, which helps the room hold its heat. For you, that means less worry about walls that swell or twist after a few wet seasons outside. ALEKO doesn't name the wood species, so ask us if that matters to you.

Is a 6 kW Heater Enough for a 5 Person Sauna?

For a 5 person sauna, 6 kW is the usual starting size, and it's the heater ALEKO pairs with this cabin. You can set your heater anywhere from 158 to 194°F with one dial. For context, 194°F is only 18 degrees short of the boiling point of water, so this heater gets properly hot. Build some warm-up time into your guest instructions, so the room is ready when they are.

How Do You Assemble a DIY Outdoor Sauna Kit?

ALEKO designed this DIY outdoor sauna kit for home assembly, and its video below walks through the build. Before your delivery day, prepare your outdoor sauna foundation: a level, solid base where the cabin will sit. ALEKO lists the footprint as 5.91 by 5.25 feet. Some retail listings show different measurements, so ask us to confirm the final size before you pour concrete or build a pad. Line up a helper and basic tools. Your electrician connects the heater once the cabin is built.

Wet or Dry: How Does a Traditional Outdoor Steam Sauna Work?

This is a traditional wet/dry sauna, so your guests choose the style. For a dry session, they sit back in the heat. For a wet session, they scoop water from the wooden bucket and pour it over the hot stones for a wave of steam. Your thermo-hygrometer shows temperature and humidity, and the sand timer helps your guests keep sessions short. Anyone who is pregnant, or has heart or blood pressure concerns, should check with a doctor before using a sauna.

Is This a Good Sauna for a Short-Term Rental?

For your rental, safety and simplicity matter most. The heater carries UL certification and shuts itself off after 60 minutes of running, so a heater left on after checkout won't run all day. Two dials run everything, which keeps your guest instructions to a few lines. Want to offer a hot-and-cold routine? Pair it with the Lumina cedar cold plunge. Post session times and house rules by the door, and your guests will use it with confidence.
