At a glance
- Two families: the all-timber tub (authentic) and the timber-clad synthetic tub (more practical, the best seller).
- Timbers: spruce (affordable), thermowood (durable), red cedar (high end).
- Wood-fired heating usually takes 1.5 to 3 hours to reach 37–40 °C.
All-timber tub or timber-clad synthetic tub?
All-timber tub
- Authentic look and scent
- Often cheaper to buy
- Must stay wet to stay watertight
- Trickier to clean, water changed more often
Fibreglass or acrylic tub
- Smooth, hygienic surface, easy to clean
- No risk of leaks if the tub stands empty
- Compatible with filtration and jets
- A little more expensive, less “raw” look
For regular use, a timber-clad synthetic tub is the best compromise: you keep the beauty of wood on the outside, without its constraints on the inside.
Timber species
| Timber | Strengths | Weaknesses | Tier |
|---|---|---|---|
| Spruce (Nordic pine) | Light, pale, affordable | Needs regular stain or treatment | Entry and mid-range |
| Thermowood | Timber heated to high temperature: stable, resistant to damp and fungi | Brown tone that silvers over time | Mid-range and high end |
| Red cedar | Naturally very durable, pleasant scent, handsome appearance | More expensive | High end |
Heating with a wood burner
The stove heats the water by contact and by natural circulation (thermosiphon). Heating time depends on the volume of water, the stove’s output, the insulation and the outside temperature: allow roughly 1.5 to 3 hours to reach 37–40 °C. Burn dry hardwood for better efficiency and less smoke.
There are two configurations, each with its advantages: internal or external stove. If you would rather skip carrying logs on weeknights, look at hybrid models that add an electric heater.
Wooden hot tub prices
Most wooden hot tubs with a stove cost between €3,000 and €5,000 for 4 to 6 seats. Small models start at around €2,000, and large, well-equipped formats go beyond €5,000. UK buyers should also budget for delivery and any import VAT or duties. See the full price breakdown.
Caring for the timber
- Apply a suitable oil or stain to the outer cladding, following the manufacturer’s recommendations.
- Cover the tub between uses to protect the water and the wood.
- With an all-timber tub, do not leave it empty in the sun for long periods.

Frequently asked questions
Which wood is best for a hot tub?
Spruce is the most common and most affordable. Thermowood (thermally modified timber) resists damp and fungi better. Red cedar, more expensive, is naturally very durable and prized for its appearance.
Does an all-timber hot tub leak?
An all-timber tub can seep when it is filled after standing dry: the wood needs to swell again to become watertight. It is therefore best not to leave it empty for too long. Fibreglass and acrylic liners do not have this problem.
How long does a wooden hot tub last?
Lifespan depends on the timber, the treatment, the care and the climate. Well-maintained timber cladding over a synthetic liner protected by a lid lasts considerably longer than an all-timber tub left untended.
