BOOK A CONSULTATIONA compact architectural column carved from solid Indian rainbow sandstone, combining natural colour, vertical water movement and integrated lighting in a relatively small footprint.
Standing approximately 50cm high and 20cm in diameter, this Caldera is designed for gardens where you want clear vertical presence without the scale of the taller 70cm sandstone column.
Water bubbles from the top before flowing over the smooth sandstone surface and travelling down the full height of the feature into the concealed reservoir below.
Once wet, the stone changes considerably in character, with softer dry tones developing into richer oranges, reds, browns and purples. An integrated LED light illuminates the top water effect after dark.
The 50cm sandstone Caldera is designed for spaces where the taller column could feel too dominant, while still providing a strong upright silhouette and full-length flowing water effect.
Tall enough to remain visible amongst low planting while being easier to integrate into smaller patios, borders and courtyards.
The slim column delivers strong visual height while taking up very little space within the finished garden.
The top water effect can be enjoyed after dark as the LED draws attention to the point where the water emerges.
Water is pumped internally through the sandstone and emerges gently at the top of the feature.
It spreads over the upper surface before flowing around the edge and travelling down the smooth stone exterior.
The water creates a thin shimmering layer across the sandstone, intensifying its natural colour before falling into the concealed reservoir and being continuously recirculated.
The simple cylindrical column form gives the Caldera a cleaner and more architectural appearance than a carved twist or irregular natural stone feature.
At approximately 50cm high and 20cm across, the proportions are compact enough for smaller gardens while retaining enough stone surface for a clearly visible vertical water effect.
Rainbow sandstone is naturally layered, with colours and mineral markings formed within the stone itself.
When dry, the surface can appear relatively soft and pastel. Once wet, the colouring becomes much stronger, revealing richer orange, red, brown and purple tones.
Because the stone is natural, the exact position and strength of those layers will vary from one Caldera column to another.
Exact colour, mineral banding, surface markings, weight and subtle dimensions can vary naturally between pieces. These differences are part of the character of genuine stone.
Natural daylight and flowing water reveal the individual layers within the sandstone, with the wet surface appearing noticeably deeper and more saturated than the dry stone.
The integrated LED illuminates the bubbling water at the top, creating a brighter focal point before the water continues down the darker stone surface.
The 50cm Caldera is particularly useful where there is not enough space for a larger sphere, bowl or taller statement column.
Its narrow footprint makes it easy to position within a planted border, beside a patio, within gravel or as a focal point in a smaller courtyard.
The warm natural sandstone also softens the clean cylindrical form, allowing it to sit comfortably within both contemporary and more traditional landscapes.
The supplied 66cm diameter heavy-duty pebble pool is installed below the finished garden surface, allowing the column to appear to rise directly from the surrounding landscape.
Select a firm, level area with access to a suitable outdoor electrical supply.
Prepare an opening for the supplied 66cm diameter heavy-duty pebble pool.
Install the reservoir securely and ensure it is level below the finished garden surface.
Position the supplied mains-powered pump inside the reservoir and connect it to the column.
Ensure the support area is stable and suitable for the approximately 60kg natural stone column.
Carefully centre and level the 50cm sandstone column over the concealed reservoir.
Conceal the reservoir with decorative pebbles while retaining suitable access for pump maintenance.
Fill the reservoir and switch on the pump. Water rises through the column and flows back into the hidden pool below.
Decorative pebbles are available separately, allowing the reservoir to be concealed and the finished installation coordinated with surrounding paving, gravel or planting.
The sandstone displays softer pastel and earthy tones, with the natural layers and mineral markings visible but relatively restrained.
Flowing water deepens the stone dramatically, bringing orange, red, brown and purple tones forward and increasing contrast between the natural bands.
Explore Caldera designs in rainbow sandstone, basalt, granite, slate and Corten, with compact 50cm columns through to taller statement features approaching a metre in height.
