Durability: How Stainless Steel and Cedar Hold Up

When buying an outdoor cold tub, durability is a big factor to consider. Both stainless steel and cedar bring their own strengths to the table when it comes to handling outdoor conditions.

Stainless Steel: Built to Last

Stainless steel stands out for its toughness, thanks to its unique composition. The chromium in stainless steel creates a protective oxide layer, making it resistant to rust and corrosion - even in tough environments. Whether it’s freezing winters, blazing summers, or constant exposure to rain, snow, and salty coastal air, stainless steel holds its ground [5]. Its solid structure ensures it remains dependable over time, making it perfect for heavy-duty, long-lasting use.

"Stainless steel is an excellent choice for outdoor use due to its exceptional resistance to corrosion, durability, and overall robustness." - Plaque Direct [5]

Now, let’s take a look at cedar and its natural approach to durability.

Cedar: Natural Protection Against Decay

Cedar takes a different route to durability, relying on its natural oils to resist decay in damp conditions [7]. Western Red Cedar, in particular, outperforms many softwoods when it comes to resisting warping and cracking [4] [7].

"When choosing the right wood for outdoor projects, durability is everything. You want materials that can withstand harsh weather, resist decay, and maintain their beauty for years." - Wagner Meters [4]

With proper care, cedar cold tubs can last 15–20 years [7] [8]. Its wood grain even contains natural air pockets, offering insulation that helps it handle extreme temperature shifts [6]. However, cedar does require regular cleaning and treatment to maintain its protective qualities [7] [8].

Ultimately, the decision comes down to whether you value stainless steel’s low-maintenance durability or cedar’s natural charm and resilience.

Looks: Modern Style vs. Natural Wood

The appearance of your cold tub plays a big role in how well it fits into your outdoor space. Stainless steel and cedar each bring their own distinct style, adding unique character to your backyard.

Stainless Steel: Sleek and Contemporary

Stainless steel offers a polished, modern vibe with clean lines and a minimalist edge. It's a great fit for urban patios, luxury decks, or commercial spaces where a sharp, sophisticated look is key. Its smooth, non-porous surface not only looks striking but is also easy to keep clean, making it a practical and stylish choice for many settings[1].

Cedar: Warm and Rustic

Cedar, on the other hand, brings a cozy, natural feel with its rich textures and warm tones. It creates a spa-like atmosphere that blends beautifully with natural surroundings and residential spaces[2]. Every cedar tub is unique, thanks to its individual grain patterns and color variations, giving it a one-of-a-kind charm.

Keep in mind, untreated cedar ages gracefully, developing a silver-gray patina when exposed to sunlight[11][12]. If you prefer to maintain its original warmth, applying a high-quality wood sealant can help preserve its natural beauty.

For those who love the best of both worlds, some designs combine cedar exteriors with stainless steel interiors, offering the inviting warmth of wood with the modern practicality of steel[10].

Maintenance: Care and Upkeep Needs

The level of maintenance required depends on the material, which impacts both the time you’ll spend on upkeep and how well the tub performs over the years.

Stainless Steel: Minimal Effort

Stainless steel tubs are relatively easy to care for, thanks to their non-porous surface that resists bacteria. For daily upkeep, rinse the tub and towel-dry it to prevent mineral deposits from forming[15]. Once a week, give it a thorough cleaning using mild soap, warm water, and a soft microfiber cloth to avoid scratches. Water spots can be removed with white vinegar or Windex[15][18].

Calcium deposits may occasionally leave a scum line, but you can minimize this by regularly wiping the surface with a microfiber cloth dampened with pool water. If tea staining occurs from prolonged non-use, it might require professional treatment. Avoid using harsh chemicals, as they can damage the surface[18].

Cedar: Higher Maintenance Commitment

Cedar tubs require more frequent attention to keep them looking great and functioning properly. After each use, sanitize the water and check the pH levels to ensure water quality stays balanced[13][14]. Taking a quick shower before using the tub and opting for non-toxic sanitizers, like ozone or hydrogen peroxide, can help reduce bacteria buildup[13].

On a monthly basis, deep clean the tub using natural cleaning products. Additionally, it’s a good idea to drain and inspect the tub 2–3 times a year. During these inspections, scrub away any buildup with a Scotch-Brite pad and check the tension hoops to ensure the wood isn’t swelling or starting to rot[13][17].

Cedar tubs also need seasonal care to maintain their longevity. Apply Teak Oil and a protective coating every 6–12 months. After applying the coating, let it cure for a full 24 hours before using the tub again[19]. Maintaining an ambient temperature of at least 65°F can help prevent wood damage, especially during colder months[19].

Water management depends on the type of system you have. For wood-fired cedar tubs without circulation systems, you’ll need to change the water every 2–3 weeks. However, tubs with electric systems that include circulation and filtration can go up to 3 months before requiring a water change[16]. Skipping these tasks can lead to faster deterioration of the wood and shorten the tub’s lifespan[9].

The maintenance requirements for each material not only affect your time investment but also play a role in long-term costs, which we’ll dig into next.

Cost: Upfront Price vs. Long-Term Expenses

When deciding between stainless steel and cedar for your outdoor cold tub, it's not just about the initial price tag. You also need to weigh the ongoing costs that come with each option. Let's break it down.

Stainless Steel: Higher Initial Cost, Lower Maintenance Over Time

Stainless steel tubs tend to have a steeper upfront cost, largely due to the materials and the complexity of manufacturing. For example, the Dynamic Cold Therapy Pacific Cedar Barrel with a marine-grade 316 stainless steel interior is priced at $3,499.00, while models with the standard 304 interior are more affordable[22].

However, the good news is that stainless steel tubs are easier on your wallet in the long run. Replacement filters cost around $6 each and should be swapped out every 20 uses[20]. Chemical treatments average about $150 and can last anywhere from 6 to 12 months[20]. Thanks to the smooth, non-porous surface of stainless steel, cleaning is a breeze, which helps minimize repair needs over time. In contrast, cedar tubs might save you money upfront but can rack up higher maintenance costs as the years go by.

Cedar: Lower Initial Price, Higher Ongoing Costs

Cedar tubs typically start at a lower price, around $4,199.00, though premium options like the VITALPLUS US Cedar Ice Bath & Chiller can go as high as $6,995. With the CEDAR1000 discount code, the latter is currently available for $5,995[21][23].

But here's the catch: cedar tubs come with higher upkeep costs. The natural properties of wood mean that temperature changes can cause expansion, leading to leaks and potential repair expenses. Each drainage and refill session costs about $2–$3, and the wood's tendency to contaminate the water might require more frequent changes[20][9]. Proper installation is crucial - placing the tub on a level, well-drained foundation can help prevent wood rot. And if you need to winterize your cedar tub, professional services for draining, scrubbing, and resealing can cost between $200 and $300[9].

Energy use is another factor. A 2.7 kW heater can take up to 20 hours to heat a four-person cedar tub, which can add a noticeable bump to your utility bill[9].

When you look at the bigger picture, cedar tubs might hold their resale value if well-maintained[8]. But for those seeking predictability and lower ongoing costs, stainless steel tubs could be the smarter long-term choice.

Conclusion: Which Material is Right for You

Deciding between stainless steel and cedar comes down to your priorities: budget, aesthetics, and how much maintenance you're willing to handle. Both materials can provide a fantastic cold therapy experience, but each has its strengths.

If convenience and modern design appeal to you, stainless steel might be the way to go. While it comes with a higher upfront cost (around $3,499), it requires minimal maintenance over time, making it a smart long-term investment. Its excellent resistance to corrosion and hygienic qualities mean you can enjoy a hassle-free experience.

On the other hand, if you’re drawn to the timeless beauty of natural materials, cedar is hard to beat. With proper care, cedar can last 25–30 years, thanks to its natural oils that protect it from decay and pests. As Stacy Kovats, Marketing Director at Issaquah Cedar and Lumber, explains:

"Cedar wood is extremely durable as well as beautiful, making it a great choice for fencing, decorative wood chips and mulching" [3].

However, it's worth noting that cedar requires more upkeep over time. Regular water changes and sealing every 3–5 years can add up, with costs typically balancing out with stainless steel around the 12–15 year mark [24].

Each material has its unique advantages: stainless steel excels in corrosion resistance and durability, while cedar offers natural insulation and a warm, inviting aesthetic. If you're planning a permanent setup where longevity is key, stainless steel might be your best bet. But if you’re after a more grounding, sensory experience, cedar’s natural warmth and aroma create a relaxing, therapeutic atmosphere.

Ultimately, the right choice depends on your lifestyle, budget, and how much effort you’re willing to put into maintenance. Select the material that aligns with your outdoor space and long-term cold therapy goals.
