Product Overview

Fujiwa RIVERA-26 Sahara is a high-performance 1" x 2" glazed porcelain mosaic tile engineered specifically for swimming pool waterlines, spas, fountains, and outdoor aquatic environments. Drawing inspiration from rich desert sands and warm mineral tones, the Sahara colorway features a multi-tonal reactive glaze blend of warm amber, bronze, subtle copper highlights, and earthy sand undertones.

Manufactured by Fujiwa Tiles, a recognized leader in aquatic and architectural ceramics, this tile features an impervious porcelain body with near-zero water absorption (< 0.5%). Pre-assembled on flexible mesh-backed sheets in a classic staggered mini-brick pattern, it is built to withstand severe freeze-thaw cycles, prolonged UV exposure, and pool chemical treatments without fading, cracking, or crazing over time.

Technical Specifications

Recommended Applications

• Swimming Pools & Spas: Pool waterline tile runs, raised spa spillways, submerged bench accents, and step marker highlights.

• Aquatic Architectural Features: Outdoor fountains, waterfall spillways, reflecting pools, and water walls.

• Exterior & Interior Surfaces: Patio wet bars, outdoor kitchen backsplashes, primary bathroom accents, and shower walls.

Installation & Handling Guidelines

⚠️ CRITICAL WARNING: AQUATIC & POOL MORTAR PROTOCOL

• Thinset Mortar Selection: Swimming pool and submerged tile installations require high-flexibility, polymer-modified thinset specified for submerged aquatic environments. Install using an ANSI A118.15-compliant latex-polymer modified mortar (such as MAPEI® Kerabond T / Keralastic System or LATICRETE® 254 Platinum).

• 100% Mortar Coverage: Achieving 100% mortar contact behind every 1x2 mosaic chip is mandatory in submerged applications. Voids or air pockets behind tiles trapped underwater can cause moisture accumulation, efflorescence, and eventual tile pop-offs.

• Grout Selection: Use a high-performance, water-resistant grout specified for swimming pools, such as a high-density cementitious grout (ANSI A118.7) or 100% solid industrial epoxy grout (ANSI A118.3 like MAPEI® Kerapoxy or LATICRETE® SpectraLOCK® Pro Premium) for maximum stain and chemical resistance.

Professional Recommendations

• Waterline Curing Time: Allow thinset and grout to fully cure per manufacturer instructions (typically 14 to 21 days minimum) before filling the pool with water or adding pool chemicals.

• Movement Joints: Install expansion joints at all plane changes, pool corners, and coping transitions per TCNA EJ171 guidelines.

Care & Maintenance

• Routine Cleaning: Clean pool waterline scale and body oils using a non-abrasive pool tile cleaner or a soft brush with pH-neutral soap.

• Chemical Balance: Maintain proper water chemistry (pH, total alkalinity, and calcium hardness) to prevent calcium scale buildup or mineral deposits along the waterline.

• Zero Sealing Required: Non-porous glazed porcelain is completely impervious to water penetration and never requires sealers or topical coatings.

Design Profile

• Aesthetic Inspiration: Desert Sandstone, Warm Coastal Earth, and Earthy Tuscan Sanctuaries.

• Glaze Characteristics: Multi-tonal running bond layout with light-refracting amber and bronze glaze variations that add warmth and depth along the waterline.

• Complementary Finishes: Pairs exceptionally well with natural flagstone or travertine pool coping, warm tan/beige or French gray pool plaster, and natural teak or concrete pavers.

Frequently Asked Questions

Is Fujiwa RIVERA-26 Sahara suitable for saltwater swimming pools?

Yes! Fujiwa glazed porcelain tiles are fully impervious (< 0.5% water absorption) and chemical-resistant, making them completely safe for both traditional chlorine and saltwater pool systems.

Can this tile withstand freezing winter weather?

Absolutely. Fujiwa pool tiles are tested and certified frost-proof (ASTM C1026). They are engineered to endure severe freeze-thaw winter cycles without cracking, spalling, or debonding when installed with proper movement joints and ANSI A118.15 thinset.

What is the advantage of a 1" x 2" running bond pattern over standard 1" x 1" tiles?

The 1" x 2" brick format offers a classic architectural look that lengthens the appearance of the waterline while providing high flexibility across radiused pool walls and curved spa steps.

Why is pool-rated thinset required instead of standard tile mortar?

Submerged pool tiles are subject to constant water pressure, chemical exposure, and thermal expansion. Standard interior thinsets will break down underwater over time, leading to tile detachment. Always use an ANSI A118.15 or ANSI A118.3 aquatic-rated thinset and grout.
