Blue Thumb Hollowed-Out Basalt Fountain Kit

Triple Basalt Columns with Pooling Water Features

The Blue Thumb Hollowed-Out Basalt Fountain Kit creates a stunning multi-column water feature with a unique twist—each basalt column features a hollowed-out top that creates a pool of water 6-8 inches deep before overflowing down the sides. This distinctive design adds visual depth and the soothing sound of cascading water to gardens and outdoor spaces of any size.

Sourced directly from premium quarries, these dense basalt columns are paired with Blue Thumb's engineered AquaBox™ basins designed specifically to support the substantial weight of natural stone. Available in three height configurations, each kit includes three graduated columns, a matched pump, flow control valve, complete plumbing, and 200 lbs of black polished pebbles for a turnkey installation.

Why Choose Basalt Fountains?

Blue Thumb works directly with quarries to source only the highest-quality basalt columns for fountain applications. These dense natural stone columns require properly engineered support—the AquaBox™ basins are specifically designed with the right thickness and structural integrity to support basalt's substantial weight without settling or collapse over time. The hollowed-out design creates a unique pooling effect that sets these fountains apart from traditional column fountains.

Note: Basalt rock color varies by supply quarry. Please contact us before purchasing for current stone color availability.

Frequently Asked Questions

Q: What makes the hollowed-out design special?
A: Unlike traditional basalt columns where water simply bubbles over the top, the hollowed-out design creates a 6-8" deep pool of water on each column. This adds visual depth and creates a more dramatic cascading effect as water overflows from the pools.

Q: Which kit size is right for my space?
A: The Short Kit (18", 24", 30") works well for compact gardens and patios. The Tall Kit (24", 30", 36") is ideal for medium to large yards and primary features. The Extra Tall Kit (24", 36", 48") creates a bold statement in estate gardens or commercial landscapes.

Q: What is included in each kit?
A: All kits include three drilled basalt columns at graduated heights, Achelous fountain basin, matched pump (GPH varies by kit), flow control valve, complete plumbing and tubing, and 200 lbs of black polished pebbles. The Extra Tall Kit also includes a splash apron.

Q: Why is the AquaBox basin important?
A: Basalt is extremely dense and heavy. The AquaBox™ basin is engineered with proper thickness and structural support to handle the weight of multiple basalt columns without flexing, settling, or collapsing over time.

Q: How does water flow through three columns?
A: The pump supplies water through plumbing that distributes flow to all three columns. Water rises through each column, pools in the hollowed-out top, then overflows and cascades down the sides back to the basin.

Q: Can I adjust the water flow?
A: Yes. Each kit includes a flow control valve that allows you to adjust the water flow rate to achieve your desired pooling depth and cascading effect.

Q: Will the basalt color be consistent?
A: Basalt color varies by supply quarry and can range from dark gray to black with natural variations. We recommend contacting us before purchase to confirm current stone color availability.

Q: Can I install this myself?
A: While the kits include all necessary components, basalt columns are extremely heavy and typically require professional installation equipment or a team for safe handling and positioning.

Q: What is the splash apron in the Extra Tall Kit?
A: The splash apron is an additional liner component that extends around the basin to catch and redirect water splash from the taller columns, preventing water loss and protecting the surrounding area.
