A Tubmarine tub being built in the Dorset workshop

In the workshop

The making, by hand in Dorset.

Before it reaches a garden, terrace or retreat, every tub passes through our workshop, where it is fabricated, welded and assembled by our small team.

The process

Time, care and precision

The internal frames, the stainless shells, the insulation layers, the finishing touches. It is a process that takes time, care and precision, and it is the reason our tubs feel solid, quiet and enduring.
