The company says the new product will be a UK first for the sector, giving customers far greater choice and control over how their spa looks and feels.
Further details will be released nearer the launch date of 1 April 2027.
Capstone founder Shaun Cremins will oversee the launch programme, covering customer experience strategy, marketing and brand development, and employee engagement.
RotoSpa’s own team will keep full ownership of product design and manufacturing.
Karl Rowntree, director at RotoSpa, said: “This is one of the most significant projects in RotoSpa’s history, and personalisation at this level simply hasn’t been done in our sector before.
“We wanted a partner who could hold the whole picture together, our customers, our team and our brand, and that’s exactly what Shaun and Capstone bring.”
Shaun Cremins said: “RotoSpa has built an incredible reputation over more than two decades as the UK’s only hot tub manufacturer, and this launch is a chance to bring that same craftsmanship to a genuinely personalised product.
“My focus is making sure the experience is exceptional at every stage, for RotoSpa’s customers and for their team, who are central to making this launch a success.”
Founded as a family business in 2003, RotoSpa says it is the only hot tub manufacturer in the UK.
Its products are installed in thousands of homes and used by hire agents, retailers, dealers and more than 300 holiday parks.
