Is the RedWood Outdoors Horizon 6 Person Traditional Sauna the Right Sauna for You?

An outdoor sauna is a big purchase, and the footprint, power, and delivery questions matter as much as the looks. This RedWood Outdoors Horizon 6 Person Traditional Sauna review is research-based, not hands-on.

It draws on the official product page and the reviews posted there. I think the Horizon suits you if you want a glass-backed barrel sauna with a covered porch and have room for the longer footprint. Plan around its “spacious for 4” rating, not just the six-seat maximum.

RedWood Outdoors Horizon 6 Person Traditional Sauna at a Glance

RedWood Outdoors Horizon 6 person outdoor barrel sauna with front porch and glass rear wall

The Horizon is an outdoor barrel sauna sold as a DIY kit. The product page lists it as “Horizon Outdoor Sauna – 6 Person w/ Porch.”

It combines a full-glass rear wall with a built-in front porch. The brand describes the porch as a covered spot to sit between heat sessions or keep towels and robes dry.

It is a traditional sauna, so an electric heater warms the room and you can pour water over the stones for steam. If you are comparing formats, this guide to the best traditional sauna options adds context. The figures below are the manufacturer’s listed specifications.

Key Features—and What They Mean for You

Heating and Controls

The included Harvia KIP is a wall-mounted Finnish heater with dual manual controls. A delay timer can be set up to 8 hours ahead.

Wi-Fi is only an upgrade on the 8kW version. The page also lists other heater options, including the Harvia Spirit and Virta and two Homecraft models, each with its own power and breaker needs.

The brand says every heater is designed for water on the stones. It also says the barrel shape heats quickly and evenly, but it gives no warm-up time or running cost. I would not guess either from the 6kW rating.

Fit and Comfort

The interior is about 5′-9″ wide and 5′-4″ long, with two facing benches. The listed 4-person comfort rating is the safer planning number.

The bench size is listed as 1′-2″ wide, which looks narrow, so check the manual for bench depth. The full-glass rear wall adds light and a view, so consider what sits behind the sauna.

The porch is the main difference from a standard barrel design. It adds roughly 2 feet of length and lets you step out between sessions, though it sits outside the heated room.

Setup Requirements

The brand says the kit needs no cutting and goes together in a few hours with basic tools. It lists a drill with a T20 bit, a mallet, a hammer, two wrenches, a tape measure, and a level.

The heater is not plug-in. A licensed electrician must hardwire it to your panel, and the brand suggests getting at least two quotes.

The base must be level and support the full weight, with the sauna’s three cradles in mind. Listed options include concrete footings, a reinforced deck, compacted gravel, or a paver patio. Check permit and HOA rules before you order.

Cleaning, Storage, and Maintenance

The brand says the hemlock needs no exterior stain or sealer and will weather to grey. Weather resistance is not the same as waterproofing, so drainage still matters.

For benches and floors, it recommends a light coat of sauna-grade paraffin oil or sauna wax. Never use stain inside.

The brand also says to wipe the heater periodically. It recommends restacking and inspecting the stones every 6 months and replacing them after 1 to 2 years.

Included Items and Additional Costs

The sauna includes the 6kW heater, stones, asphalt shingles, backrests, a towel peg, a doormat, and one felt hat. Freight is calculated at checkout.

Optional extras on the page include a flat floor ($399), a beveled roof kit ($799), a Fenix controller upgrade ($599), an LED light bar ($329), and stone upgrades ($20 to $95). Electrician fees, the base, and moving the crate are not included.

Weight and Dimensions

Sauna weight: 1,150 lbs.
Porch size: 5′-9¼” W x 1′-11½” L.
Crate size: 3′-10″ W x 7′-1″ L x 2′-5″ H.
Door: tempered glass with wood frame, 1′-11¼” W x 4′-8¼” H.

Where It Works—and Where It Falls Short

The Horizon has clear strengths and a few practical catches. Most of the strengths come from manufacturer claims and customer posts, not independent testing.

What Stands Out

Full-glass rear wall for light and a view.
Built-in covered porch for cooling off or keeping towels dry.
Heat-treated hemlock, listed at 1½” thick.
Pre-cut kit with a printed manual and online assembly videos.
Includes a 6kW Harvia KIP heater, stones, and shingles.
Several heater choices, per the product page.
Exterior needs no stain or sealer, per the brand.

What to Consider

“Spacious for 4” is well below the six-seat maximum.
At 1,150 lbs. and about 7′-8″ long, it needs more space than a model without a porch.
Electrician, base, and freight add to the price, and the page showed it out of stock.

I think the Horizon makes sense if you want the view and a place to cool off, and you can plan the site and power first. It is less convincing for regular groups of five or six.

Who Should Consider the RedWood Outdoors Horizon—and Who Should Skip It?

This May Suit You If…

You have a level outdoor spot with room for the porch, a base, and an electrical run.
You usually sauna with one to four people.
You want a place to sit outside the hot room and a glass view inside.

You May Prefer Another Option If…

You need an indoor sauna, or a plug-in model with no electrician.
You regularly sit six adults together.
Your yard is tight or your delivery access is restricted.

What Do Customers Say About the RedWood Outdoors Horizon 6 Person Sauna?

The product page shows 5.00 out of 5 from 6 reviews, all labeled for this model. This is the brand’s own site, so I did not combine it with any other platform.

Themes are easy assembly, helpful staff, and the view. Two reviewers mention a “Panorama” sauna, which may be an earlier name, and the page does not say.

I found no negative reviews or long-term durability reports in these six. Keep that in mind, since the sample is small.

One reviewer said “Setup was easy and the customer service was amazing,” per the product page reviews.
Another reported the sauna “Was pretty easy to assemble,” and called the staff “great, attentive.”
A third said they needed a friend to help because the front and back walls were too heavy to lift alone.
The same reviewer said the electrical work took the longest because the panel was nearly 100 feet away.
A fifth said the barrel design fits neatly into their landscaping.

One reviewer’s heater was the 8kW KIP, not the included 6kW, so that comment does not describe the standard package.

Questions to Ask Before You Buy

Where can you buy it?

The official product page is the verified source. Check stock and your heater package first, since all three packages showed as unavailable.

What should an electrician confirm?

The 6kW KIP lists 240V and a 30A breaker, while other heaters need different breakers. Ask about panel capacity, wire distance, and local code before you order.

How does delivery work?

The brand ships by freight and requires a signature. The crate is left at the curb, and carriers will not move it into a backyard. Contact support first if access involves steep, gated, or unpaved roads.

What does the warranty cover?

The sauna has a 1-year limited warranty. Harvia heaters carry 1 year on heating elements and 5 years limited on other parts for residential use. Read the full warranty terms, and ask about returns before you pay.

How should you use water on the stones?

The brand says its heaters are designed for it. Follow your heater’s manual, and talk to your doctor if you have health concerns about heat.

Final Verdict: Is the RedWood Outdoors Horizon 6 Person Traditional Sauna Worth Considering?

I think it is worth considering if you want a glass-backed outdoor barrel sauna with a covered porch and have a prepared site. This RedWood Outdoors Horizon 6 Person Traditional Sauna review suggests the best fit is a household of up to four that values the view and a simple DIY build.

The decisive benefit is the porch. The main trade-off is the larger footprint and total cost against the $7,099 listed price. Before ordering, confirm stock, the heater package, shipping, electrician quotes, your base plan, and local rules, then check the official product page for current details.
