The Rock — 6mm Waterproof SPC (Republic Floor)

The Rock is a rigid-core SPC line from Republic Floor, built for rooms where water and daily wear are a given. Each plank runs 6mm total with a stone polymer core, a 20 mil wear layer, and an attached acoustic EVA underlayment, so the pad is already built in and no separate underlayment goes down at install. Planks measure 9″ x 60″ and join with an angle-drop click-lock system for a floating, glue-free install rated for above, on, or below-grade subfloors. The line ships in 6 colors spanning medium greys, light browns, and medium beiges, backed by a 50-Year Residential / 10-Year Commercial warranty and FloorScore certification for indoor air quality. The Rock is available to order through our Santa Clara showroom.

Colors in The Rock

The Rock’s 6 colors group into three families: a medium grey (Ellen), light browns (Filitosa, Zurich Tan), and medium beiges (Ivory Buff, Ivory Fantasy, Splendor Satin). That range gives you a cool, contemporary option alongside warmer neutrals, so the line works whether the room leans toward a modern grey palette or a softer, traditional wood tone. Every color shares the same 6mm SPC build, so the choice comes down to look, not performance.

Best uses for The Rock

• Kitchens and bathrooms — the SPC core is genuinely waterproof with no time limit, so spills and splashes aren’t a risk.
• Basements — rated for above, on, or below-grade installation, including slab-on-grade basements.
• Pet households and high-traffic rooms — the 20 mil wear layer and rigid core hold up to claws, foot traffic, and rolling furniture.
• Open-concept living spaces — the 9″ x 60″ plank and click-lock system run continuously from room to room without transitions.
• Rooms with radiant heat — compatible with hydronic and embedded radiant systems, provided the floor surface stays at or below 85°F.

Choosing a color from The Rock

In a bright, south-facing room the cooler grey of Ellen keeps things crisp, while the light browns and beiges — Filitosa, Ivory Buff, Ivory Fantasy, Splendor Satin, and Zurich Tan — read warmer and hide daily dust better in lower-light rooms or spaces with darker cabinetry. Because SPC color can shift slightly under different lighting, bring a sample home or view it under your own room’s cabinetry and fixtures at our Santa Clara showroom before ordering.
