Aqua Moda Caldera / Pre-Weathered Corten Steel

Caldera Corten Steel 90cm Column Water Feature

A tall architectural water column combining a slim 20cm footprint with 90cm of vertical Corten steel and continuously moving water.

This is the larger of the Caldera Corten columns and is designed for spaces where the water feature should have a stronger visual presence without becoming physically wide or bulky.

Water rises through the centre before flowing over the top and down the four steel faces, creating a shimmering vertical surface against the warm pre-weathered Corten finish.

The simple geometric form makes it particularly effective within contemporary landscapes, where the contrast between clean lines, rust-toned steel, planting and moving water can become a defining feature of the space.

The taller Corten Caldera — slim in footprint, strong in vertical presence. 90cm high / 20 x 20cm column / Pre-weathered Corten steel

Why choose the 90cm Corten Caldera?

Choose the taller column when you want the feature to hold its own within the landscape.

Increasing the height to 90cm gives the Caldera considerably more presence while retaining the same compact 20 x 20cm footprint.

01 / STATEMENT HEIGHT

90cm vertical profile

The taller proportions make this version easier to see above planting and from further across the garden.

02 / CORTEN CHARACTER

Warm weathered steel

The rust-toned Corten surface softens the geometry of the column and provides a natural contrast against green planting.

03 / SLIM FOOTPRINT

Still just 20 x 20cm

The extra height does not require a wider column, making it possible to create significant impact in relatively narrow spaces.

The 90cm Caldera water effect

A longer vertical water path creates a more dramatic cascade.

Water is pumped internally through the column before emerging from the top of the feature.

It spreads across the upper surface and flows over each edge, travelling down the four vertical Corten faces.

At 90cm high, the water has considerably more distance to travel than on a lower feature, creating a larger moving surface and more visible reflections across the weathered steel.

Top water source Water emerges from the top of the column.

Four-sided flow Water travels across all four faces of the square profile.

90cm vertical cascade The taller column creates a longer visible journey for the water.

Hidden return Water falls into the concealed reservoir and is continuously reused.

Tall architectural proportions

A simple square column stretched vertically for greater impact.

The Caldera deliberately avoids decorative detail. Its appeal comes from proportion, material and water movement.

Extending the column to 90cm while retaining its 20 x 20cm section gives this version a noticeably leaner and more architectural silhouette than the 70cm model.

90cm Tall vertical column height

20cm Column width

20cm Column depth

Pre-weathered Corten steel

Warm colour and natural variation within a precise geometric form.

The column is manufactured from 1.5mm Corten steel and arrives pre-weathered with the distinctive orange-brown tones associated with weathered steel.

This gives the clean architectural shape a warmer and more organic quality than painted or polished metal.

Corten works particularly well within garden settings because the rust-toned surface provides strong contrast against green planting while remaining sympathetic to timber, gravel, stone and other natural landscape materials.

Natural tonal variation is part of the finish

A Corten surface is not intended to look completely uniform like painted steel. Differences in tone and weathered appearance are part of the material's architectural character.

Designed to stand out

The taller Caldera works particularly well where the feature needs to be seen from a distance.

At 90cm high, this version can hold its own within larger planting schemes and more open landscape designs.

Position it amongst grasses or evergreen foliage for strong colour contrast, against a contemporary wall for a cleaner architectural composition, or at the end of a sight line to create a defined visual destination.

Despite its extra height, the narrow 20cm footprint keeps the feature practical for spaces where ground area is limited.

Concealed reservoir installation

Hide the working system and leave the 90cm column visually uninterrupted.

The supplied reservoir measures approximately 66cm in diameter and 40cm deep. Installed below the finished surface, it allows the tall Corten column to appear to rise directly from the surrounding gravel, paving or planting.

Choose the position

Select a firm, level location with access to a suitable outdoor electrical supply.

Excavate

Prepare an opening for the 66cm diameter reservoir, allowing for its approximately 40cm depth.

Level the reservoir

Install the pool securely and ensure it is level beneath the finished landscape surface.

Install the pump

Position the mains-powered pump inside the reservoir and connect the water feed to the column.

Position the column

Centre the 90cm Corten column securely over the reservoir and ensure it stands vertical.

Check the flow

Run the pump and adjust the water flow so it distributes cleanly over the top edges.

Finish the surface

Conceal the reservoir with decorative pebbles or your chosen landscape finish while retaining maintenance access.

Fill & enjoy

Water continuously cycles from the reservoir, through the column and back into the hidden pool below.

No permanent water supply required This Caldera uses a self-contained recirculating water system, so no permanent plumbing connection is required. The supplied pump is mains powered and includes a 10m cable. Periodically top up the reservoir to replace water lost through evaporation and splash.

Complete water feature kit

Supplied with the main components required for installation.

90cm Corten Steel Column Pre-weathered 1.5mm Corten steel column measuring 90cm high x 20cm wide x 20cm deep.

66cm Pebble Pool Reservoir Concealed water reservoir measuring approximately 66cm diameter x 40cm deep.

Mains-Powered Pump Suitable recirculating pump supplied with a 10m electrical cable.

Self-Contained System Water continuously recirculates between the reservoir and column without requiring a permanent water connection.

Decorative pebbles are available separately, allowing the reservoir to disappear beneath a finish chosen to complement the Corten steel and surrounding landscape.

Weathered steel and moving water

The taller surface gives water more room to transform the appearance of the steel.

When dry

The column displays the warm orange-brown tones and natural variation of pre-weathered Corten steel.

When flowing

Water darkens sections of the surface and adds moving highlights across the full 90cm height, making the steel appear more dynamic and visually layered.
