In the Caribbean, where outdoor living is central to the experience of the home, the luxury swimming pool is rarely an afterthought. At the finest residences, it becomes something more: architecture, landscape and art held in a single frame of water.

For more than 25 years, Miami-based artisan Ray Corral has been creating underwater artworks that belong firmly in that category. Through his company, Mosaicist, Inc., he has earned an international reputation for transforming pool interiors into hand-crafted works composed from thousands of individually cut pieces of glass. Commissions span from Miami to destinations including Cyprus, Switzerland, Abu Dhabi and throughout the Caribbean.

Stand beside a completed pool and the effect registers at once: sunlight fracturing across Venetian glass, colour deepening and softening through the day, a floor reading as mural, water as part of the composition.

FROM STAGE TO STUDIO

Corral’s route into mosaics was far from conventional. Born and raised in Miami, he spent his early years in the city’s 1990s music scene, working as a percussionist before another creative language began to call. “I performed at night and made mosaics during the day, selling
them on consignment,” he recalls. “I grew a passion for mosaic art.” He travelled throughout Europe to study traditional techniques, learning the discipline of hand-cutting tesserae, the small pieces of glass or stone from which a mosaic is built, setting patterns and understanding how colour, texture and geometry work together within a composition. Those lessons remain central today, rooted in patience, precision and the human hand.

THE CONVERSATION COMES FIRST

Every custom pool design begins not with tile samples but with conversation. Corral meets with clients to understand the architecture, the surrounding landscape, how the pool will be used and the atmosphere they hope to create. Some seek classical symmetry and old-world detailing. Others want contemporary minimalism, reef-inspired movement or a family crest worked into the floor.

“Since 90% of my jobs are new construction, I get the architect’s plans of the unbuilt pool and design on top of it,” he explains. “I consider the architectural style of the home and its relation to the surrounding landscape.”

Concepts are refined into scaled renderings, then developed into layouts that map every curve and tonal shift across the pool structure. Because pools are often viewed from terraces and upper floors, designs must perform from multiple vantage points.

CHOOSING THE MATERIALS

Materials are chosen with equal care. Venetian glass and Italian smalti remain favoured for their depth of colour and ability to hold light beneath water. Iridescent finishes create movement as the sun travels across the surface. Earth glass tones add warmth, while select projects incorporate gold-leaf glass, in which a fine sheet of precious metal is sandwiched between two panes of molten hand-blown glass to produce a shimmer.

Every material must also withstand chlorine, salt, UV exposure and constant immersion, with colour stability weighed alongside aesthetics so the work remains beautiful for decades.

THE MASTER’S HAND

Corral’s craft has been shaped by several masters of the discipline, a handful he counts as lifelong mentors and under whom he apprenticed. Of notable mention is Master Mosaicist Luigi Scodeller, who for many years was the commercial director of the respected Perdomo Family – MVM mosaic studio. Scodeller was a formative influence from Corral’s earliest years. Following Scodeller’s passing, that mentorship has continued through Master Mosaicist Giuseppe Semeraro, a leading figure on the industrial manufacturing side of the mosaic industry. Both trained and taught at Scuola Mosaicisti del Friuli in Spilimbergo, founded in 1922 and widely regarded as one of the world’s most prestigious mosaic institutions, where Corral himself now lectures.

In the Studio and On Site

Fabrication remains hands-on. Each piece of glass is cut and shaped by hand. Sections of the composition are dry-assembled first so tones can be adjusted by eye, then fixed onto numbered panels so they travel intact. On-site, Mosaicists’ in-house installation artists transfer and align each section with millimetre precision.

“Underwater mosaic applications remain relatively young compared with centuries-old mosaic traditions,” Corral notes. “It’s still a specialist discipline and one that is evolving.” Grouts and adhesives are now selected specifically for submerged environments, ensuring permanence and longevity.

DESIGNED FOR THE CARIBBEAN

For a Caribbean pool, a mosaic must be intimate at close range, striking from above and built to endure chlorine, salt, UV exposure and years of constant immersion. Many residences are built around negative-edge pools designed to read as extensions of the sea. Before a single tessera is cut, Corral studies the colour of the water at the time of year owners will most often be in residence. “A lot of clients want me to match the colour of the sea in their pools,” he explains. “We study the average hues and tones, then manufacture custom colour tones and glass finishes to tie the whole environment together.”

When marine life enters a design, species are always native to the region, rendered with accurate colouring and drop shadows so the scene reads as biologically real from above. “It makes the experience as real and relatable as possible,” he says.

The best of these pools give themselves up slowly. First the field of colour, then the pattern, then, the longer you look, a quieter layer of detail beneath.

A Ray Corral mosaic pool is, of course, a place to swim. It is also a place to pause, to look through clear water and see that luxury, in the right hands, can still be made piece by piece.
