Inside every tub
Built by hand, ready at a touch
Both sizes share the same materials and details. Choose a feature to see it up close.

Touchscreen control
Set your temperature and jets from a simple touch panel on the rim. The integrated heater holds the water at temperature automatically, so it’s ready the moment you are.
Set it and step in
12 or 24 directional jets
Twelve jets in the 2-person and twenty-four in the 4-person deliver a targeted, full-body massage and keep the water circulating. Aim them where you want them and dial the pressure to suit.
Targeted massage
Ambient lighting
Soft built-in lighting turns an evening soak into something special, casting a gentle glow across the water once the sun goes down.
Made for evenings
Easy-access filter
The filter sits within easy reach for cleaning, with no dismantling and no tools. Keeping the water fresh is a simple, regular job rather than a chore.
Simple maintenance
316 marine-grade stainless steel
The tub and exterior surfaces are built from 316 marine-grade stainless steel, inside and out, the same alloy used for boat fittings. Every seam is hand TIG welded.
Built to last outdoors
Kebony timber cladding
Clad in Kebony, a sustainably sourced, modified softwood with hardwood-like durability. It weathers to a soft natural silver and needs no oiling or staining.
No oiling or sealing required
Optional access steps
Matching Kebony steps with brushed stainless legs and black powder-coated sides make getting in and out easy, and sit perfectly alongside the tub. Available as an optional extra.
Optional extra · £550, or £650 in black
Limited Edition
Also in black
The same handbuilt tub in 316 marine-grade stainless steel and Kebony timber, finished in a deep, weather-fast black. Quietly dramatic, and built in a limited run each year.
Effortless by design
How it works
No fire, no waiting, no fuss. Set the temperature once and your tub stays ready, whenever the mood takes you.
Set your temperature
Choose your temperature on the simple touchscreen panel. Just the number you want.
It heats & holds
The integrated heater brings the water up to temperature and holds it there automatically.
Jets & lighting on
Switch on the massage jets and the soft ambient lighting, all from the same panel.
Step in & relax
With the heat already there, a soak is never more than a moment away.
Good to know: day to day there’s very little to do. The easy-access filter rinses clean in minutes, and the insulated body and cover keep running costs low. Keep the water balanced with a suitable sanitiser; the water-care pack in our builder has everything you need to start.
Before it arrives
What your tub needs
A solid, level base and a power supply. No plumbing or water connection, and we’re always happy to advise on your spot before you order.
Minimum supported base
The base must support the tub’s full footprint, so it’s fully supported across its full width and length. Heights are to the top of the tub body, excluding the cover.
A level base and a power supply
- Concrete: a level slab at least 100mm thick on a well-compacted MOT Type 1 sub-base (min 75mm deep). The most reliable option.
- Paving slabs: laid flat and level on a well-compacted MOT Type 1 sub-base (min 75mm deep).
- Decking: only if it’s solidly built and rated for the full weight of the tub, water and bathers.
- Adjustable feet on both sizes fine-tune small variations in level on the day.
- Power: a dedicated 32A supply in the UK and Europe, connected by your electrician. No water connection or plumbing needed.
Delivery
Getting it into place
Your tub arrives as a single unit. In the UK, our team installs it and arranges the lift if it’s needed, with any crane or telehandler hire included in your quote.

If it can be driven to the spot
A telehandler lifts the tub off the delivery truck and drives it to where it will sit. It needs a firm, fairly level route from the road, wide enough for the machine.

If it has to go over a house or wall
A crane lifts the tub over buildings, walls or fences and sets it down in place. We’ll check where the crane can park and for overhead cables or trees.
Outside the UK, both can be hired locally with an operator, and we’ll send your lifting company the dimensions, weight and lifting details. The tub weighs around 500 kg (2-person) or 600 kg (4-person) empty.

What owners say
Exceptional quality and craftsmanship
It offers a unique blend of durability and elegance, making it a perfect addition to any home. The Tubmarine hot tub has exceeded my expectations.Richard G · CornwallElectric hot tub

How much power does the tub need?
A dedicated power supply, with no water connection or plumbing. In the UK and Europe, that’s a 32A supply. In the USA, it’s a dedicated 240 V, 40 A circuit, installed by a licensed electrician. The 3 kW heater maintains the water temperature automatically, so the tub is ready whenever you want it.
How noisy are the pumps?
The tub runs at a low noise level in circulation mode, thanks to anti-vibration mounts and the motor design. It’s comparable to a modern fridge, around 40 dB or lower.
Can I use the tub in winter?
Yes. All our tubs are fully insulated and come with an insulated cover, giving excellent heat retention and comfortable year-round use, even in colder temperatures.
What are the lead times?
Every tub is handbuilt to order in our Dorset workshop, which takes 12–16 weeks from order. In the UK, delivery and optional installation are usually scheduled within a week of completion. Shipping to Europe takes around 1–2 weeks, and to the USA around 4–5 weeks, door to door. Rest of the world: shipping time on application.
Do you offer installation?
In the UK, yes. Most installs take a day. Pricing is £650 within 100 miles of our Dorset workshop and £930 within 200 miles. Beyond that, price on application. Outside the UK, we deliver your tub and work with your local builder or electrician, advising on siting, the base and the power connection.
Do you ship abroad?
Yes. Each tub is delivered fully assembled and fully insured in transit, and can travel in a secure, custom-built timber crate. For European orders, prices are shown excluding VAT, and local VAT is payable on delivery. For the rest of the world, local import taxes and duties are payable on delivery. US customers can see US pricing and shipping here.
How do I pay?
All prices are in pounds sterling. UK prices include VAT. A 50% deposit secures your build slot, and the balance is due one week before delivery (UK) or one week before shipping (outside the UK).
What is the warranty?
We offer a 10-year structural warranty on the stainless steel shell and Kebony timber, covering manufacturing defects and material failure. Heating equipment, pumps, plumbing and electrical components, and the lid and steps, are covered for 2 years. Normal wear, natural weathering of the timber and maintenance items are excluded. Full terms are in our Terms & Conditions.
How do I look after the stainless steel?
Wipe with a soft microfibre cloth, always in the direction of the grain to preserve the brushed finish. A gentle stainless cleaner handles light marks. For water spots or limescale, a limescale spray works well but must be rinsed off and dried. Avoid abrasive sponges and harsh chemicals.
How do I look after the Kebony timber?
Kebony is low maintenance by design. No sealing or oiling is required, and it weathers naturally to a silver-grey patina. To keep the original brown colour, apply a clear UV-protective finish annually. Clean once or twice a year with warm water and mild detergent, using a soft brush rather than a pressure washer.
