Why Huatulco?

A range of spas so good, we put our name on them!  Castle Hot Tubs have partnered with the UK’s market leading distributor of hot tubs to bring you the Huatulco Range.

Before re-joining the family business in Pembrokeshire, Castle Hot Tubs Sales Director, Yan Koob lived and worked as a diving instructor in the beautiful Huatulco National Park region of Mexico.

Less developed than Mexico’s mainstream resorts, Huatulco’s bays and coves are home to many stunning scenic beaches.  Boasting fine white sand and kissed by the Pacific Ocean in shades from cobalt blue to emerald green.

We can’t think of anywhere else we would rather take some time out than Huatulco – but our hot tubs certainly come close!


Exceptional Build Quality

Our spas are built by one of the world’s largest hot tub manufacturers, at the worlds’s largest hot tub factory in China.  The spas undergo a thorough build checklist, but they also are fully tested and inspected in the factory to ensure your spa is built to our highest standards.

American Aristec Acrylic means that your hot tub not only looks great but is one of the best available.  It’s hard wearing and long-lasting.

The Huatulco hot tub range uses Gecko electronics, one of the best control boards and panel systems available.  Based in Canada, Gecko are experts at delivering state-of-the-art electronic components and they rigorously test their products in the harsh Canadian climate down to -40 degrees C.

Our superior LX Hydrotherapy Pumps deliver the ultimate powerful massage experience.

Advanced SpaQuilt Insulation

Control running costs

Our Advanced SpaQuilt Insulation offers our users one of the most efficient running hot tubs with optimal heat retention in the market.  Built for the most extreme conditions that Wales has to offer.  Our Advanced SpaQuilt Insulation uses the heat generated from the pumps to keep your hot tub warm, reflecting this heat back into the spa whilst keeping out the colder outer air.  This ultimately reduces your running costs so that you can sit back and relax for years to come.
