Product Details

LA4000 – 4×4 Fountain Basin

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.

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.
