Cultured marble for showers is an engineered stone product specifically formulated to meet the demands of wet, high-humidity shower environments, combining the luxurious aesthetic of natural marble with enhanced durability, moisture resistance, and low maintenance. Composed of 70–80% crushed natural marble aggregate (sourced for consistent color and texture), 20–25% low-VOC unsaturated polyester resin (compliant with GREENGUARD indoor air quality standards), and pigment additives (to replicate natural marble hues like white with gray veining, beige with gold veining, or soft cream), this product addresses the limitations of natural marble in showers—such as high porosity and susceptibility to etching from soap or cleaning chemicals—while retaining a premium look. GHY STONE, a premier manufacturer since 1992, produces cultured marble for showers through a precise manufacturing process: first, the marble aggregate is finely ground to a uniform particle size (0.1–0.5mm) to ensure smooth texture; then, it is mixed with resin and pigments in a vacuum mixer to eliminate air bubbles (preventing internal voids that could trap moisture); the mixture is poured into custom molds (available for shower walls, shower pans, niches, and thresholds) and vibrated to ensure full mold penetration; finally, it is cured in a temperature-controlled oven (65–75°C) for 3–4 hours to achieve a dense, non-porous structure, followed by precision cutting and surface finishing. Key performance characteristics include water absorption of ≤0.1% (ASTM C97, far lower than natural marble’s 0.3%), making it impervious to mold, mildew, and water damage; resistance to etching from soap scum, shampoos, and pH-balanced cleaning chemicals (tested per ASTM D1308); flexural strength of ≥10 MPa (resisting cracking from temperature fluctuations between hot showers and cool air); and slip resistance of R10 (for shower pans, per EN 14411, ensuring safety when wet). Surface finishes are tailored to shower functionality: honed finishes (matte, roughness ≤0.8μm) hide water spots and reduce glare, ideal for family bathrooms; polished finishes (gloss level 70–75 units) replicate high-end natural marble, suited for luxury hotel suites; and satin finishes (subtle sheen) balance aesthetics and practicality for residential master bathrooms. A clear, acrylic topcoat is applied post-finishing to enhance stain resistance and ease of cleaning, eliminating the need for frequent resealing (unlike natural marble). Installation is streamlined for both residential and commercial projects: shower walls are mounted using polymer-modified mortar (for concrete or waterproof drywall substrates) or peel-and-stick backing (for non-destructive renovations); shower pans are installed with a pre-sloped design (2% gradient) to ensure proper drainage, sealed at edges with silicone caulk to prevent water leakage; and niches/thresholds are custom-fitted to match wall panels, minimizing grout lines (1–2mm) and reducing cleaning needs. Maintenance is simple: daily rinsing with warm water to remove soap residue; weekly cleaning with a non-abrasive, pH-neutral cleaner (e.g., mild dish soap diluted in water); and occasional polishing with a cultured marble-specific cleaner to restore shine. GHY STONE’s sustainable practices include recycling excess material (scrap is ground and reused in new batches) and using energy-efficient curing ovens, aligning with eco-friendly building goals. Whether used in residential bathrooms, budget-friendly hotel showers, or multi-family housing complexes, cultured marble for showers delivers reliable performance, luxurious design, and low maintenance, embodying GHY STONE’s commitment to innovative, premium stone solutions for wet environments.
