Stainless Steel
Wood-Fired Hot Tubs
A testament to relaxation that seamlessly blends natural elements with opulent design
The Tubmarine wood-fired hot tub is about slowing down and doing things properly. Fire, water, and timber—combined without complication or excess.
There is something deeply satisfying about heating your tub with real fire. The ritual of lighting it, tending it, and watching steam rise as the water warms becomes part of the experience, not a chore, but a moment to disconnect. No screens. No noise. Just heat, water, and time.
Built from marine-grade stainless steel where it matters, a powder-coated structural frame, and Kebony timber cladding, every wood-fired Tubmarine is designed to live outdoors for years—not seasons. It is as much a piece of outdoor furniture as it is a hot tub made to look better as it becomes part of its setting.
This is bathing that encourages you to slow down and enjoy the moment.

FAQs
-
Fill the tub with fresh water using the built-in tap (this can be plumbed in) or a hose.
Light the fire in the stove and keep it stocked with dry logs only.
Stir the water regularly while heating, as the top layer will warm faster than the rest.
Check the temperature – once it feels comfortable, it's ready to enjoy.
If it's too hot, add a little cold water through the tap.
After use, drain the water within a couple of days. No chemicals are needed, as the tub is designed for fresh water use.

Every Tubmarine hot tub and ice bath is built using premium marine-grade stainless steel for all visible and water-contact surfaces, paired with Kebony® wood — a sustainable, high-performance material known for its durability and beautiful finish. Beneath the surface, each tub is supported by a powder-coated steel internal framework, engineered for strength and long-term stability. These materials are chosen for their resilience in all weather conditions, low maintenance, and timeless aesthetic, ensuring your Tubmarine stays looking and performing at its best for years to come.
-
All our hot tubs and ice baths are meticulously handcrafted in Dorset, England.
-
We recommend a level concrete base at least 100mm thick, laid over a well-compacted MOT Type 1 sub-base (min 75mm deep). This ensures stability and proper drainage. Paving slabs or timber decking are acceptable alternatives, provided they're laid on an equally stable and level foundation capable of supporting the tub's weight when filled with water and users. The base must also be sized to match the specific tub model ordered, ensuring full contact and support across the footprint.
-
Yes! All our hot tubs are fully insulated and come with fully insulated lids, ensuring excellent heat retention and comfortable year-round use - even in colder temperatures.
-
Our current production lead time is 12-14 weeks.

Use a soft microfiber cloth to clean all stainless steel surfaces.
Always wipe in the direction of the grain to preserve the brushed finish.
For light marks and daily use, we recommend using a gentle stainless steel cleaner such as Cif Perfect Finish Stainless Steel Cleaner.
For removing water spots or limescale, Cif Limescale Remover Spray works well—but it must be thoroughly rinsed off with clean water and then dried with a microfiber cloth to prevent new marks.
Tub Interior Cleaning:
A soft-bristled broom is ideal for sweeping out the floor of the tub, allowing you to clean without stepping inside.
Only clean the tub interior when fully drained.
Avoid using abrasive sponges or harsh chemical cleaners that could damage the surfaces or affect water quality.
Regular care like this will help keep your Tubmarine looking its best and performing well for years to come.
-
Kebony is a natural wood product treated for durability, making it low maintenance by design. However, there are a few things you can do to keep it looking its best:
No sealing or oiling is required – Kebony is designed to weather naturally to a silver-grey patina over time when exposed to sun and rain.
If you prefer to preserve the original brown colour, you can apply a clear UV-protective wood finish annually.
Clean the surface once or twice a year with warm water and a mild detergent to remove dirt, pollen, or algae.
For stubborn grime or stains, use a soft brush or cloth—never a pressure washer, as this can damage the surface fibres.
If needed, you can lightly sand the surface to remove marks or restore a smoother appearance.
Avoid leaving damp items or planters directly on the wood for extended periods, as this can trap moisture and cause discolouration.
-
Each Tubmarine hot tub is delivered fully assembled and securely enclosed in a custom-built timber crate for maximum protection during international shipping. Every shipment is fully insured throughout transit, giving you complete peace of mind from dispatch to delivery.
