Wooden vs Fiberglass Wood Fired Hot Tub: Which One Should You Choose?
When choosing a wood fired hot tub for your backyard, the decision often comes down to a traditional all-wooden tub or a modern fiberglass-lined alternative. While both deliver the authentic experience of wood-burning heat, they differ significantly in maintenance demands, durability, and long-term ownership cost.
Whether you’re considering a 2 person wood fired hot tub for private relaxation or a larger family model, understanding these differences is essential. At Baltresto, we design wood fired hot tubs for sale that combine Scandinavian craftsmanship with long-term reliability – especially through advanced fiberglass construction.
1. Understanding Wooden Wood Fired Hot Tubs
A pure wooden hot tub is crafted entirely from natural woods like spruce or thermowood. These tubs provide an authentic, eco-friendly experience with a soothing wood aroma that elevates your soak. Heating via a wood stove is efficient, often reaching ideal temperatures in 2-3 hours, and they’re budget-friendly upfront.
Pros of Wooden Hot Tubs:
- Eco-friendly and natural materials that blend seamlessly with outdoor settings.
- Lower initial cost compared to fiberglass models.
- Quick heating and a rustic, therapeutic vibe.
Cons:
- High risk of leaking over time due to constant wood expansion and contraction
- Ongoing maintenance requirements, including regular moisture control and water retention to prevent the wood from drying out
- Sensitive to climate conditions, especially freezing temperatures and prolonged periods of non-use
- More demanding winterization and storage if not used year-round
- Shorter service life, typically 10-20 years, even with careful upkeep
2. Exploring Fiberglass Wood Fired Hot Tubs
Fiberglass hot tubs feature a wooden exterior with a durable fiberglass liner. This hybrid design maintains the classic look while adding modern perks, making it ideal for frequent use. The liner ensures leak-proof performance and easier cleaning.
Pros of Fiberglass Hot Tubs:
- Completely leak-proof construction – no swelling, shrinking, or resealing required
- Significantly longer lifespan, commonly 20-30+ years
- Minimal maintenance: easier cleaning, faster water changes, and superior hygiene
- Excellent thermal stability, especially in colder climates
- Lower total cost of ownership over time despite higher initial price
Cons:
- Higher upfront cost due to the reinforced liner
- Less “pure” natural feel compared to all-wood models
