GMT Spas International

Born out of the concept to manufacture superior quality spas, using the best materials available GMT Spas International was set up in 2008 by Managing Director, Darren Tillyer.

GMT Spas International supplies mosaic tiled spas, swim spas and hydrotherapy pools. The unique business model of supplying only to the trade and not installing, enables the company to concentrate on, and remain true to its ethos of manufacturing superb high-end pools.

GMT Spas International's in-house design team uses the latest Solidworks 3D computer technology with the recent addition of a program that enables the design team to stress test a spa before it has even been built.

The desire for bespoke, out of the ordinary and something different continues to grow. Add to this the endless tile choices that are now available and the finish of any project can be truly unique.

Due to this increased demand GMT Spas International recently invested in a new production method that has enabled it to save time in the manufacturing process whilst also improving quality and accuracy of the finished item.

Marine grade gel coats and resins, stainless steel leg kits with adjustable feet, and industry approved adhesives and grouts are used in the manufacture.

GMT Spas International's success is entirely due to its conscientious and highly talented team.

Mirimar Hotel

The brief for this spa was to manufacture a large mosaic tiled oval spa to sit above ground level. The spa had to include an integrated mosaic tiled skirt to allow the spa to be dropped into place quickly. Due to access issues of the building, the spa also had to be manufactured in two sections and joined on site. One of the first issues GMT Spas had to overcome was incorporating the joining flange and volcano feature in the spa without increasing the height of the spa too much. This was achieved by altering the stainless steel support frame.

Another issue that had to be taken into account was allowing access to all of the jets and features, as there was no access from below. This was achieved by incorporating hidden tiled access panels in the surrounding skirt.


This project was a new spa to sit on the deck of a yacht. The main design features required were to incorporate a curved glass panel with stainless steel trim as well as panels to surround the spa. Installing a pre-made curved glass panel meant GMT Spas had to work to high tolerances when manufacturing the pattern. This was also the case with the stainless steel trim and outer panels. The high level of accuracy was added to further by the stringent requirements for spas installed on yachts.

The customer wanted a large spa with loungers and external steps for a high end ski chalet. The client chose a large slate mosaic tile finish. This meant altering the features used in the spa to allow for the thickness of the tile whilst still providing an enjoyable user experience and a high end look to the finished product.
