There are plenty of acrylic spas. Tubmarine is something different — each tub is designed with restraint, built by hand in Dorset, and made to sit beautifully in its surroundings for decades, not years.
316 Stainless Steel
Marine-grade throughout. The same grade used in saltwater environments. No rust, no degradation, no compromise.
Kebony Timber
Sustainably sourced softwood, thermally modified to achieve hardwood durability. It weathers beautifully and needs no sealing or oiling.
Built to Last
10-year structural warranty as standard. Designed to age well and become a permanent part of its setting — not replaced every five years.
Made in Britain
Every weld, every joint, every piece of timber — handbuilt by our team in Dorset, England. No outsourcing, no shortcuts.
Built for a lifetime.

Our Tubmarine is still perfect and it easily must have been filled and used over 1,000 times. We are so happy with it.

Before you enquire
What to expect.
A few practical answers, so you have what you need before getting in touch.
It depends on the tub. Wood-fired tubs can be delivered and built on site, or — for tighter spots — lifted in by HIAB and dropped into position. Electric tubs arrive as a single unit and are craned or HIAB-lifted into place where access allows. Our two-person soaking tubs and ice baths can be mounted on wheels and rolled into position by hand. We'll always agree the right method with you before delivery day.
Typically 12 to 16 weeks, depending on the product and the time of year — we get busier in certain seasons. We'll confirm a firm timeframe for your tub when you enquire.
Almost anywhere. We've installed in London townhouses with no rear access from the road by craning the tub in, so difficult sites are rarely a problem. To assess yours, we usually just ask for a short video walking from the front of the property to where the tub will go, and we'll check access on Google Maps too. In practice, we've always found a way.
Made by hand.
Finished with care.
Every Tubmarine begins with laser-cut stainless steel and ends with hand-polished welds and individually selected Kebony timber. There are no shortcuts in the process — because the process is what makes the product.
