Here’s why Western Red Cedar is the ideal cedar wood for hot tubs and why you should care. I like to use it for its very consistent smell. It performs exceptionally well in both dry and wet climates, holding its shape for decades.

The wood has a deep, warm luster and hue that’s easy to appreciate. Its pleasant, smooth texture provides you with a very crisp aesthetic without the risk of splinters. Further, bugs and mold don’t affect its performance as much, allowing less frequent maintenance.

The natural tight grain of the wood creates an excellent seal. This type of design locks water in and does a good job of preventing heat loss. These features add up to you spending less time on care and maintenance and getting more time to enjoy and relax.

The substance of this post explains each of these ideas in depth.

Which Cedar Reigns Supreme for Tubs?

Cedar hot tubs are well known for their rustic beauty, sturdy construction and natural warmth. Choosing the best cedar wood has a huge impact on how your tub looks, feels and withstands the test of time. You’ll encounter several different general varieties among what’s available, each with its advantages. Understanding these is key to choosing the right one for your specific needs.

1. Western Red Cedar: Popular Choice

Western red cedar is a popular choice for hot tubs. Light reddish-brown color with fine, straight grain make this wood warm and attractive. This durable wood resists the effects of excessive rain and sun, and natural oils in the wood help prevent rot and insects.

Due to its unique cellular structure, its fibers trap air, aiding in the retention of water warmth while using less energy. It’s no surprise that most leading brands, such as Roberts Hot Tubs, choose western red cedar for these advantages.

2. Alaskan Yellow Cedar: High Density

Alaskan yellow cedar delivers a combination of density and strength that’s hard to beat. Its tight grain gives it strength and durability, allowing it to withstand years of heavy use. Highly resistant to insect infestation, water and rot, it’s a perfect fit in damp locations.

The kicky pale yellow color and delicate pattern of lines create a decidedly fresh and airy appearance. It’s stiffer than western red cedar so it retains its shape better. It’s a little less pleasant to handle because it’s heavier.

3. Northern White Cedar: Lighter Feel

Northern white cedar stands out for its naturally pale, buttery hue and smooth satin finish, which gives cedar hot tubs a clean, airy look. Its lighter weight makes it easier to work with during construction and transport, especially for first-time buyers or those building in tight spaces.

Beyond aesthetics and convenience, northern white cedar is also a practical choice. It contains natural oils that deter insects and resist decay, making it ideal for damp or cold climates. Where other timbers might struggle with moisture and mold, this variety holds up exceptionally well—offering longevity and peace of mind.

4. Comparing Cedar Density Impacts

The density of cedar wood significantly affects both performance and maintenance. Alaskan yellow cedar, being denser, offers greater durability and superior heat retention, making it ideal for long, hot soaks. In contrast, northern white cedar is lighter, easier to handle, and needs less upkeep—perfect for low-maintenance hot tub enthusiasts.

 

Cedar Type	Density (lb/ft³)
Western Red Cedar	23
Alaskan Yellow Cedar	31
Northern White Cedar	21

 

5. How Natural Oils Vary by Species

All three species produce oils, but red and yellow cedar have significantly greater amounts than white cedar. These oils repel water, mold, and insect, making tubs last exponentially longer.

Western red cedar is renowned for deep saturated oils, helping prevent the tub from warping for decades.

6. Assessing Mold and Rot Resistance

While all three cedars resist mildew and decay, concentrated oils present in both red and yellow cedar enhance this quality even further. Sealing the wood with a water repellant certainly adds an additional layer of protection.

Areas that are dark, damp, low, or poorly ventilated are likely to grow the most mildew. In furthest support of this, cedar undeniably outlasts pine or fir in these markets.

7. My Personal Experience and Pick

Among all the options explored, western red cedar stands out for its ideal mix of beauty, warmth, and low-maintenance appeal. Key factors to weigh include price point, the space available for the tub, and the preferred level of upkeep.

Western red cedar offers less hassle and more years of enjoyment. It’s wise to reflect on what truly matters before making a final decision.

Cedar Against Other Wood Types

If you’re wondering what the benefits of cedar wood are, here’s everything you should know about selecting the best wood for building your hot tub. Cedar’s fine grain, particularly that of Western Red Cedar, prevents it from cracking or warping. This fragrant wood naturally stands up to decay, wards off moisture, and protects against bacteria without any added safeguards.

As cedar tubs can easily be heated by wood-firing, electric, or gas, they provide more options than their counterpart woods. You’ll see people in urban and rural areas equally choosing cedar for its beauty, character, and durability.

Cedar vs. Teak Showdown

Feature	Cedar	Teak
Rot Resistance	High	Very High
Moisture Repel	Strong	Excellent (natural oils)
Upkeep	Needs sealing, easy	Less sealing needed
Cost	Lower, budget-friendly	High, premium price
Look	Warm, red-brown, knots	Golden-brown, smooth

 

Teak has a well-earned reputation for standing up to water and rot due to natural oils. It is more expensive to stay ahead, but you don’t pay a premium to do so. Cedar is easy on your wallet and still will last you decades with proper care.

Cedar’s warm color, characterized by its knots and rich reds, provides a more rustic appearance. Teak, on the other hand, is smoother and more golden, more subtle.

Cedar vs. Redwood Comparison

Feature	Cedar	Redwood
Durability	Strong, long-life	Good, less tough
Rot Resistance	High, natural	Moderate, needs help
Look	Red-brown, rustic	Lighter, pinkish
Cost	More affordable	Higher, less common

 

Both cedar and redwood naturally resist rot enough to be used for hot tubs without added protection. Redwood tends to photograph more pink, too. Cedar is more widely available and fits a broader budget.

When it comes to the long run, cedar truly delivers on resisting the elements and maintaining its form.

Brief Look at Other Woods

Other woods such as pine, oak, and spruce occasionally appear as hot tub woods. Pine lumber may be inexpensive, but it twists and cracks and decays before your eyes. Oak is hard, durable, but weighs a ton and requires extensive maintenance.

Spruce is as light as cedar, but far more vulnerable to the elements. These woods require a great deal of specialized treatment, and they’re more difficult to find in the proper size. Cedar’s combination of long life, low care, and easy purchasing continues to make it the overwhelming favorite among most buyers.

Factors Influencing Your Cedar Choice

Some practical considerations that might affect which cedar you opt for in your hot tub. Each of these factors will contribute greatly to how your tub looks as well as how long it lasts. To get the most bang for your buck, first you should know what to look for. It’s well worth it to do your homework before you purchase. Let’s take a closer look at some of the most important factors to consider.

Wood Grain and Texture Impact

The grain and texture of cedar will help define the style and vibe of your hot tub. Straight-grain cedar produces a beautiful, clean, uniform look, but swirling or knotty patterns provide character that really pops. The tactile sense, the feel under your fingers, is different as well.

Planed, fine-grain boards absorb so much light they seem to shimmer, while rougher cuts add a rustic texture to any space. These seemingly artful patterns are rooted in functionality. That’s because the dense, fine straight grain causes water to bead and roll off the surface, preventing it from seeping in and causing damage.

Others may have close to 100% heartwood, as this is the densest and most durable component of the tree, providing added longevity to some tubs. For a clean, contemporary aesthetic, choose fine-grained boards. If you want that cabin-in-the-woods look, choose knotty cedar.

How Climate Affects Performance

Where you’re located directly impacts how your cedar bathtub will fare over time. In dry, temperate environments, cedar naturally resists decay and insects with minimal maintenance. In very humid or rainy areas, you will have to go above and beyond when it comes to maintenance.

Extreme fluctuations in temperature can be tough on the wood, so choosing cedar that’s appropriate for your climate conditions is important. With consistent maintenance and a careful cleaning routine, you can keep your tub around for many years to come. With the proper match, you’ll receive decades of use from it.

Treatment Options: Seal or Age?

Sealing your cedar locks in color and blocks out moisture, so the tub keeps its rich look and resists wear. If you let it age, it develops its own beautiful gray color and patina with time and creates a clean, understated look.

Just don’t forget to watch out for splinters and regularly wash the wood. If you’re looking for less maintenance, go with sealing. For a more casual vibe, allow it to mature.

Compatibility with Heating Systems

Cedar performs well with electric heaters as well as wood-fired heaters. Its natural insulating properties help hold warmth inside, meaning the water requires less energy to stay warm. Some woods like teak need little sealing due to their natural oils.

When treated properly, cedar lasts for decades and it runs more than 70% more efficiently than most other tubs. Your heating method can dictate how much maintenance you’ll require and how the wood will perform.

Keep Your Cedar Tub Thriving

With regular maintenance, the rewards are well worth the effort—cedar hot tubs are known for their impressive longevity. A little special attention goes a long way in keeping the tub healthy, clean, and inviting for years to come.

Cedar’s natural oils make it highly resistant to rot and moisture. When cleaned and sealed consistently, it performs exceptionally well. Even if the tub eventually needs replacing, this approach can significantly extend its lifespan. And of course, that rich, natural cedar scent will be lingering all around—making every soak even more enjoyable.

Smart Cleaning and Sealing Tips

Rough scrubbers are never used—only soft cloths or sponges are suitable for cleaning the surface. Warm water combined with a bit of mild soap effectively removes dirt without damaging the wood. Non-abrasive cleaners are essential, as cedar is naturally smooth and preserving that texture is important.

The tub should be rinsed thoroughly after each use to prevent soap buildup and grime. A high-quality sealant, specifically formulated for cedar, is recommended for sealing. Re-sealing the wood twice a year—once in the spring and again in the fall—helps protect against water penetration and premature decay.

Keeping the water at a cooler temperature, ideally between 90–105°F, also helps extend the wood’s lifespan. Daily monitoring of the water ensures it remains free of contaminants and stays properly balanced.

Prevent Rot and Water Issues

While cedar naturally resists moisture, it’s still important to take steps to prevent rot. Ensure there is proper drainage beneath the tub, avoiding any situation where it might sit in a low spot that collects water. At least two inches of insulation under the tub helps with both heat retention and reducing water pooling.

Keep an eye on the water level and make sure it never drops below the jets, as prolonged exposure to air can cause the wood to dry out and eventually crack. Regular weekly inspections are recommended—check for soft spots, leaks, and any loose boards. Addressing small issues early helps prevent major damage over time.

Essential Seasonal Maintenance Guide

• Drain the tub and clean it at the beginning of each season.
• Reseal the wood in spring and fall.
• Check all jets, seals, and pipes for leaks.
• Add or check insulation under the tub.
• Keep the cover clean and dry.
• For winter: drain the tub if not used, cover tight, and add insulation.
• For summer: rinse the tub often, keep water balanced, and watch for algae.
• Store in a dry, shaded spot, and check for pests.

Choose Sustainable Cedar Sources

Choosing the best cedar for a hot tub begins with its source location. When you choose cedar that’s been harvested from sustainably managed forests, you’re directly helping to restore the planet. Your decision improves your local community in the process.

Indeed, all of our cedar hot tubs are made with timber from managed forests that are continuously reforested, so the process continues. Looking for wood certified by reputable standards, such as the Forest Stewardship Council (FSC), helps guarantee that accountability. You can be confident that the lumber has been traced from harvest through to retail sale.

These certifications ensure that the wood was harvested with both wildlife and future forests in mind. Choosing sustainable cedar allows you to curl up in your bathtub confident that you’ve contributed to the preservation of healthy forests.

Why Eco-Friendly Sourcing Matters

Forests that are clearcut irresponsibly lose far more than just trees. Clearing forests removes homes for wildlife and disrupts the natural flow of water across the landscape. By choosing cedar sourced from responsibly managed forests, you support efforts to curtail this loss.

When you support sustainable forestry, you are supporting scientifically-based regulations that protect soil, water and wildlife. Ultimately, this cycle sustains forests for the next generation of people and wildlife.

We craft our hot tubs from sustainably-harvested Western red cedar. This remarkable wood is incredibly hardy, resistant to insects and decay, and it naturally breaks down safely when it no longer serves a purpose. Another feature that’s got everyone interested is that these tubs use 90% less water than traditional hot tubs. Their guests love the fact those tubs easily biodegrade all by themselves.

Check Cedar Availability Locally

Seeking cedar options closer to home makes sense. Local wood will usually perform better in whatever climate the tub may be located. Purchasing local means you are supporting small businesses and mills that create jobs in your community.

You further reduce shipping fuel by cutting down on transport distance. Request documentation of sustainably harvested wood, look for product reviews, and ask your fellow buyers how their tubs are performing.

Companies like Roberts Hot Tubs Inc use Canadian cedar from known sources, giving you a tub that lasts and keeps the planet in mind.

Balancing Cost and Cedar Value

When shopping for cedar hot tubs, price plays an important role, but long-term value is just as critical. Cedar comes in a range of grades and price points, and selecting the right type involves more than just considering the initial cost—it’s about what the material offers over time in terms of durability and aesthetics.

There’s a common belief that cheaper alternatives like acrylic will save money. However, a closer look at the numbers reveals a clear difference in longevity and the maintenance required to keep those materials looking good. It’s not just about spending less upfront—it’s about making an investment that continues to pay off in the long run.

Understanding Cedar Price Points

As of April 2025, the pricing for cedar hot tubs varies based on the type of cedar used, size, and customization options. Here’s an updated overview:​

Western Red Cedar Hot Tubs

Western Red Cedar remains a popular choice for its natural beauty and resistance to decay. Prices for these tubs typically range from $3,259.95 to $4,689.95, depending on the model and customization options. 

Alaskan Yellow Cedar Hot Tubs

Alaskan Yellow Cedar is known for its strength and durability. Hot tubs made from this wood are generally priced between $4,219.95 and $12,009.95, with variations based on size and features. 

Port Orford Cedar Hot Tubs

Port Orford Cedar is prized for its fine grain and resistance to moisture. These tubs are typically custom-built and are priced between $9,790 and $15,940, reflecting their premium quality and craftsmanship. 

Please note that prices can vary based on specific requirements and additional features. It’s advisable to contact manufacturers directly for the most accurate and up-to-date pricing.

Considerable effort goes into determining these prices. Higher grades of wood, grain pattern (such as vertical grain) and place of origin are all important.

For instance, vertical grain is more expensive, but you receive greater durability and longevity in return. It really helped me to understand the value of paying for quality versus just going with the lowest bidder.

If you’re trying to establish a budget, focus on the future. Account for minor repairs and the first year of maintenance. Tannins may leach out, and they require care to scrub and clean.
