Tubmarine, which comes with a 25-year guarantee, heats up in under two hours and requires no electricity and minimal maintenance, according to its manufacturer.
The hot-tub is made from 80% recycled materials and costs £15,450, including VAT.
“When I set up Tubmarine, I realised that I needed to use a timber that would complement the robustness of the stainless steel,” said Chris Galley, founder. “I needed a hardwood, but it had to be sustainable. After much research, I came across Kebony and it ticked all the boxes: durable, stable, environmentally friendly and aesthetically beautiful. It’s central to the stylish design and I’m delighted with the result.”
