Natural stone · Flowing water · Garden
Water begins within the stone.
A bubbling rock fountain conceals its pump and reservoir, leaving the stone and water in view. Water emerges from the drilled stone, flows across its surface and returns to a closed circuit. Shape, texture and scale determine whether it gently bubbles, spreads in a sheet or forms a small cascade.
How the water circulates: Water circulates through a closed system. The pump sends it up through the stone under controlled pressure, where it emerges in a smooth flow at the top.
The fountain principle
Its defining feature is where the water emerges: from inside the stone.
A Revisage bubbling rock fountain is a designed water feature with a closed circuit. Water travels upwards through the drilled natural stone, emerges at the top and follows the rock’s natural contours back down.
The pump sends water up through a vertical bore in the stone, usually 32 mm in diameter or 50 mm for large monoliths. The circuit is self-contained, with no connection to natural groundwater.
At the outlet, a film of water spreads over the rock. Small fissures, quartz veins and hollows guide its path. The pump sets the flow rate; the stone shapes the pattern.
At the base, water passes through the decorative gravel and load-bearing grate back into the reservoir. The gravel catches suspended debris, while the enclosed tank keeps the water cool.
Construction · Cross-section
The cross-section shows how a typical in-ground fountain is assembled. Above ground, only the stone and decorative gravel remain visible. The reservoir, pump and supply connections sit below ground level.
A PE or GRP basin buried in the ground for the closed water circuit. Installation depth: 35 cm. Diameter: Ø 55, 66, 90, 125 or 150 cm, depending on the model.
The pump sits inside the reservoir. The hose connects to its upper outlet; the power cable usually leaves the pump housing at the rear or side.
The hose fits onto the pump’s outlet and runs through the cover into the stone’s drilled bore.
The internal bore carries the pumped water through the hose to the outlet at the top of the stone.
Water emerges at the highest point and spreads across the stone's surface.
The water film follows the stone’s natural contours and mineral structure.
The load-bearing cover spans the reservoir and supports the stone. Decorative gravel conceals the cover and allows water to return through openings in it.
Water drains through the gravel and cover back into the reservoir.
The opening in the cover provides access to the pump. The power cable also leaves the reservoir through this opening.
The thin cable is shown separately from the hose. It rises inside the reservoir, passes through the access hatch in the cover and continues above the tank.
Stone shapes & water paths
The shape of the rock determines the water’s path. Upright columns, broad boulders, terraced ledges and stacked slabs each create a different appearance and sound.
Vertical presence
Upright monoliths and pointed columns form vertical landmarks in the garden. Water emerges at the top and divides into parallel rivulets along steep ridges. The stone’s height determines its presence in the surrounding space.
Natural calm
A boulder has irregular rounded contours and a grounded presence. Water gathers in naturally weathered hollows before gently flowing over the rock’s edges into the gravel bed.
Horizontal expanse
Inspired by the natural limestone terraces of the Aegean, these low stones have broad horizontal ledges. Water briefly gathers on each level, spreads across its width and falls in fine curtains over the edges.
Architectural layering
Hand-selected gneiss slabs are stacked to create a series of water steps. The flow drops from level to level, producing the liveliest and most audible water sound in this family of stone fountains.
Selected natural stone fountains
Six distinct stones reveal different ways for water to flow. The photographs show how each form responds to gravity, surface texture and light.
Austrian marble in a natural boulder shape. The weathered surface guides water through many fine channels. The total installed height and visible stone height differ most in this design.
Crystalline white marble with delicate violet mineral veins. A film of water gives the fine veining greater depth.
Dark grey to deep black marble with snow-white calcite veins. The wet stone reflects ambient light strongly and stands out against pale walls.
A low terraced stone in amber-coloured onyx marble. Water rests in shallow hollows before flowing over gentle edges. Its footprint determines the space it needs.
Carefully stacked gneiss slabs in warm earthy tones. Water follows the collection’s longest visible route, flowing over up to nine separate steps.
A precisely cut natural stone block in Mustang slate, Azul Macaubas quartzite or granite. The geometric form connects natural stone with modern patio design.
Surface texture & water flow
Ridges divide the flow, steps form pools and edges create drops. The stone’s surface, from fine crystals to rough cleaved faces, determines how the water moves.
Geology & colour when wet
Four stone families from the Revisage collection, compared when wet. Water intensifies their appearance: dry, matt surfaces reveal deeper colours beneath a film of water.
Marble combines dense calcite crystals with natural veining. Under a steady film of water, violet, graphite and amber tones gain visual depth.
Sourced from Scandinavian deposits, Lappland Green offers a cool, emerald- and moss-green counterpoint to classic marble varieties. Extremely resistant to weathering.
Woodstone gneiss has strong horizontal banding and warm earthy tones reminiscent of wood. In the cascade design, the slabs are carefully stacked into a stepped structure.
The Quad designer fountain gives the bubbling stone principle a precise geometric form. Mustang slate, Azul Macaubas or Blue Pearl granite frame a calm, reflective water surface.
Scale & Dimension
Three measurements matter when planning a garden water feature: visible stone height, reservoir diameter and weight. A low terraced stone can need more ground space than a tall marble column.
Installation & Integration
The standard system for natural stone fountain sets. The reservoir rim sits flush with ground level. A heavy-duty grate supports the stone and decorative gravel, concealing the pump and connections below ground.
The Quad designer fountain can also be configured with a freestanding solid natural stone basin. This visible reservoir forms a base that sits naturally within patio paving.
The systems are not interchangeable: a standard natural stone fountain set with an in-ground tank cannot simply be converted to a freestanding basin. Check the requirements of the specific product before planning the installation.
Garden planning & setting
Boulders sit naturally among grasses, ferns and flowering perennials. Leave space around the planting to keep fallen leaves away from the access hatch.
The fountain’s decorative gravel can flow into a wider gravel area. The border catches splashes and creates a clear edge for maintenance.
Upright monoliths mark paths and entrances as sculptural landmarks. They need a level base and enough distance from walkways to limit wind-blown spray.
Near a seating area, the sound of water becomes part of the setting. For paved surfaces, choose the Quad with a visible basin; in-ground tanks belong in a planting bed.
Professional planning & construction
Eight practical points for a lasting installation and protection against frost. Consult a specialist for difficult ground conditions or complex landscaping.
A complete natural stone fountain set often weighs 150–600 kg, including the stone, water and decorative gravel. A compacted, stable bed of gravel or sand is essential.
The excavation size depends on the diameter of the specific reservoir (Ø 55, 66, 90, 125, or 150 cm). Revisage reservoirs have a standard installation depth of 35 cm; the rim of the reservoir sits flush with the surrounding ground level.
Natural stones have irregular contact surfaces. Ensure the stone is positioned securely on the support grid so that it cannot tip over; for tall, slender columns, mechanical anchoring is recommended.
The supplied submersible pump has a 10 m earthed power cable. It requires a weatherproof outdoor socket protected by a residual-current device (RCD). Route the power cable separately from the water hose through the access hatch.
The water flow can be precisely adjusted using the throttle valve. Plan for a border of decorative gravel at least 30–50 cm wide around the rock to reliably catch any water splashed by the wind.
Optional LED rings in warm white, blue or RGB colour change illuminate the water at the drilled outlet. Lighting is included as standard on the Quad designer fountain.
Even with a closed-loop system, water evaporates on hot days; the level in the reservoir should be checked regularly. Before the first frost, the system must be drained, and the pump should be stored in a bucket of water in a frost-free location.
Natural stone forms over time within the earth. Variations in crystal structure, veining and edges are part of its character.
Related fountain designs
Sphere fountains share the same underground circulation system. Water flows across a precisely ground sphere; on floating-sphere models, the ball rotates continuously.
Multi-part stone features such as the Woodstone cascade connect these designs. Bubbling rock fountains emphasise water flowing over stone; waterfalls and cascades focus on its free fall.
