Natural basalt character in handcrafted GFRC
The columns are cast from molds of real basalt formations, capturing their rugged texture and irregular profiles while weighing substantially less than comparable solid-stone pieces.
Complete recirculating fountain kit · SKU LA7950R
Create a large-scale outdoor focal point with three handcrafted GFRC columns molded from real basalt formations. Rising 42, 54, and 66 inches, this coordinated kit delivers the rugged texture and varied heights of a natural column grouping with a matched underground reservoir, two pumps, flow controls, automatic water fill, plumbing, splash protection, and your choice of polished pebbles.
Built as one matched system
The visible columns, structural support, recirculation equipment, plumbing, and finishing materials are coordinated for this specific three-piece display.
The columns are cast from molds of real basalt formations, capturing their rugged texture and irregular profiles while weighing substantially less than comparable solid-stone pieces.
The 42-, 54-, and 66-inch columns build vertical rhythm and layered water movement for entrances, landscape islands, gardens, and other prominent outdoor settings.
The buried Altum AquaBox® holds the two included pumps and plumbing beneath the decorative pebble surface, so no open pond is required.

Installation overview
This overview is for purchasing and site planning. Follow the supplied instructions and linked manuals for the complete installation procedure.
Select a prominent outdoor location with enough room for the basin and splash apron, plus practical access to water and GFCI-protected power.
The Altum guide calls for a hole slightly wider than the basin and 21 inches deep. Remove sharp rocks and roots, then level and compact a sand or small-gravel base.
Keep the basin level, orient pump access toward electrical service, install the center support, and compact backfill. With a splash apron, follow the manual’s below-grade and slope guidance.
Position the pumps beneath the access panel, route tubing clear of molded support points, and connect the single and double manifolds, ball valves, and included auto-fill kit.
Use handling equipment and help appropriate for pieces up to approximately 180 pounds. Position the columns for the planned view and install the GFRC Cable Support Kit as directed.
Fill with clean water before powering the submerged pumps. Adjust each flow with the ball valves, check splash return, and cover the grate with the selected polished pebbles.

Key details to confirm before choosing your finish and installation site.
Yes. It includes the three GFRC columns, cable support kit, Altum AquaBox® basin with screen, two Mag-Drive pumps, single and double manifolds with ball valves, three tubing sets, automatic fill kit, splash apron, 320 pounds of polished pebbles, and installation instructions. Site work, utilities, labor, exterior lighting, and landscaping are not included.
No. Water returns through the decorative pebble surface to the concealed 220-gallon Altum reservoir and is recirculated by the two submerged pumps.
The visible columns are 42, 54, and 66 inches tall. Beneath them, the Altum AquaBox® measures 52.5 × 52.5 × 20 inches high. The kit also includes a 10 × 10-foot liner splash apron, so plan beyond the basin edge for grading and splash return.
Choose Dapple Gray, Chestnut Brown, or Dark Espresso. Chestnut Brown and Dark Espresso require approximately a two-week lead time.
No. The kit includes 320 pounds of polished pebbles in the one color you select: Black or Mixed.
Plan nearby dry, flood-protected GFCI electrical service for the two three-prong pump plugs. The included ABDAUTO kit connects to a 1/2-inch water line or garden hose to replace water lost through evaporation.
No. The installation requires excavation, a level and compacted base, plumbing and utility connections, and safe handling of columns weighing up to approximately 180 pounds each. Plan a qualified crew and suitable lifting equipment; professional installation may be appropriate.
No. Exterior accent lights visible in lifestyle imagery are not listed as kit components. Lighting, plants, edging, and surrounding hardscape or landscape materials are sold or supplied separately.
Before prolonged freezing weather, unplug, remove, clean, empty, and protect the pumps from freezing; also protect vulnerable plumbing and the auto-fill line. Do not automatically drain the buried basin. Follow the supplied instructions and Blue Thumb’s current GFRC winter-care guidance for the correct reservoir level and procedure for your installation.
