Flume Grey Sintered Stone
Flume Grey sintered stone presents a warm grey tone with a clean, uniform surface and minimal patterning that lets the colour do the work. There is a quiet authority to it that suits contemporary and minimalist interiors where restraint is a deliberate design choice rather than an afterthought. At 20mm, the slab has the presence and durability to match its understated character.
The neutral grey palette makes Flume Grey one of the more adaptable surfaces in the sintered stone range. It sits comfortably alongside white cabinetry, timber accents, concrete finishes, and dark metal hardware without pulling focus in any direction. A reliable foundation that makes the design around it feel more considered.
At 20mm, Flume Grey is well suited to high-traffic benchtops, outdoor entertaining areas, and commercial applications where a clean, consistent surface needs to perform reliably over the long term.
Resistant to heat, staining, and scratching, with zero sealing required. Built for daily use across both interior and exterior applications.
Best For: Outdoor benchtops, kitchen benchtops, bathroom vanities, splashbacks, feature walls, large format flooring

Grigio Alexis’s sintered stone draws the eye immediately. A soft ivory canvas layered with bold grey and earthy veining, this 12mm slab has the kind of natural movement and tonal depth that makes large format applications genuinely impressive.
Brown and cream tones weave through the ivory backdrop in a pattern that feels both structured and organic. It works hardest on feature walls and kitchen islands, where the full scale of the veining can be appreciated. In smaller applications, it adds richness without crowding the space.
This 12mm slab needs no sealing, no special care, and no compromise. Resistant to heat, staining, and scratching, it handles busy kitchens and commercial environments without showing it.
Best For: Feature walls, kitchen benchtops, bathroom vanities, splashbacks, flooring, exterior cladding

Antalya sintered stone brings together subtle grey tones and intricate natural patterns in a surface that feels both sophisticated and quietly serene. The cloudy veining and textured finish give this 12mm slab a depth and movement that works beautifully across modern and classic interiors alike.
The muted grey palette makes Antalya practical across a range of applications. It sits comfortably alongside warm timbers, cool-toned cabinetry, and natural materials without competing for attention. The result is a calm, considered aesthetic that lets the space breathe.
The 12mm format handles benchtops, flooring, and wall cladding with ease. Resistant to staining, scratching, heat, and chemicals, and never needs sealing. A surface that performs as well outdoors as it does in the kitchen.
Best For: Flooring, wall cladding, kitchen benchtops, bathroom vanities, splashbacks

Nero Basaltina sintered stone replicates the natural character of Basaltina stone in a consistent dark grey surface with subtle shading that gives it depth without pattern. This 12mm slab is understated in the best possible way, a surface that brings weight and texture to a space without relying on veining or movement to do it.
The slight tonal variation across the dark grey base is what keeps Nero Basaltina from feeling flat. It reads differently in natural and artificial light, shifting between a cool charcoal and a softer, warmer grey depending on the setting. A reliable foundation for contemporary interiors where consistency of tone matters as much as colour.
Resistant to heat, staining, and scratching. Zero sealing, zero upkeep, just the surface doing its job.
Best For: Kitchen benchtops, bathroom vanities, splashbacks, feature walls, flooring, exterior cladding

Calacatta Luxe sintered stone lays warm gold and fine grey veining across a crisp white base in a satin finish that sits somewhere between polished and matte. This 12mm slab has a refinement to it that works across a wide range of interiors without ever feeling out of place.
The satin finish is what sets Calacatta Luxe apart. It picks up light gently rather than bouncing it back, allowing the gold and grey veining to shift and move depending on the time of day. Morning light draws out the warmth of the gold. Cooler light in the evening lets the grey take over. It is a surface that looks different every time you walk past it.
Resistant to heat, staining, and scratching, with zero sealing required. A surface built for heavy use, indoors and out.
Best For: Kitchen benchtops, bathroom vanities, splashbacks, feature walls, flooring, exterior cladding
The Calacatta Luxe slab is available to view at our Sydney or Newcastle showroom. The satin finish, in particular, needs to be seen under real light.
