Blue Thumb 4x4 Fountain Basin

4x4 Fountain Basin PROUDLY MADE IN THE USA! • Our 4' x 4' fountain basin is great for small fountains • Holds 70 gallons • Dimensions 49.5" square x 12" high • Max. Static Load 750 lbs. • Comes complete with basin, grate, & screen • Lifetime Warranty Overview The 4×4 GFRC Fountain Basin is crafted in Saginaw, Michigan, and built specifically for smaller, lightweight fountains. Blue Thumb’s GFRC basins feature a flat, reinforced top deck, recessed plumbing channels for clean hose routing, and a dedicated manifold pocket to support professional installation. Note: Always follow your fountain kit’s recommended basin specifications. Heavy point-load fountains, such as stone or large vase fountains, may require an AquaBox® Basin for proper long-term stability. Why This Basin Stands Out Ideal for small fountains — holds 70 gallons and designed for fountains with minimal water motion. Durable construction — supports up to 750 lbs. of static load. Complete setup — includes basin, grate, and screen. User-friendly design — flat deck, recessed plumbing channels, and manifold pocket for easy installation. Specifications Capacity: 70 gallons Dimensions: 49.5" × 49.5" × 12"H Max Static Load: 750 lbs. Includes basin, grate, and screen Made in the USA and backed by Blue Thumb’s longstanding commitment to quality. Lightweight Basin Comparison Mini Fountain Basin (PB1946): 16" × 16" × 16"H — 12 gal — Cube — For fountains up to 12" tall. 2×2 Fountain Basin (LA2000): 25" × 25" × 8"H — 12 gal — Square — For smaller fountains with minimal movement. 4×4 Fountain Basin (LA4000): 49.5" × 49.5" × 12"H — 70 gal — Square — Ideal for small fountains with low water activity. Medium GFRC Basin (PB1953): 30" × 34" × 14"H — 41 gal — Hex — For lightweight fountains up to 24" tall. Large GFRC Basin (PB1960): 40" × 46" × 14"H — 82 gal — Hex — For lightweight fountains up to 36" tall. How It Works The 4×4 basin acts as a concealed water reservoir that continuously recirculates water through a compatible fountain. Its recessed plumbing channels allow hidden hose routing, and the internal manifold pocket supports multi-outlet fountain setups. A reinforced deck distributes load evenly while the pump-access area ensures straightforward maintenance.
