Our Paradise Water Features have a very gentle water movement element to them where the water comes up through the centre of the bowl and flows over edge of the bowl, along the underside of the bowl and then back into the reservoir. They are perfect for creating a peaceful ambience in any space. it is a very simple but effective product that is easy to install with virtually no ground-prep needed.

The water feature is made up of; a corten steel water bowl (60 or 80cm diameter, with a brass hose fitting added to the bottom centre), a pump (PONTEC ‘PondoCompact 800’ 230V, 50Hz, 20W with a 10m cable), hose (approximately 75cm) and, a reservoir/sump (Finia Water Feature Reservoir 65cm or 100cm). Additionally, for the RAISED PARADISE WATER FEATURE there is a corten steel ring that the reservoir sits inside of.

Included; Decorative polished pebbles stones to cover the top of the reservoir – these are available in Black. We recommend putting pebbles in the bottom of the bowl to disrupt the water flow from the pump feed – this is because the water fed into the bowl can match the movment of the water in the bowl, causing a resonance that creates waves that increase in size, spilling water unevenly over the edge of the bowl.

Please Note: Images are of the Raised Paradise Water Feature – The corten bowl supplied may be at any stage of the weathering process – Corten steel will weather under water but at a very reduced rate – As the corten bowl weathers it will emit rust particles into the water, turning it an orange-brown colour – We recommend weathering your corten bowl dry and then sealing it using an appropriate corten steel sealer for maximum water clarity.

Corten Steel, also known as weathering steel, is renowned for its incredible strength. It starts out as a blue steel but during the weathering process, develops a protective oxidisation layer with a striking rust appearance. This creates a warm rich aesthetic that is not usually associated with metal.

Step-by-Step Corten Steel Weathering Guide

  • Stage 1 – Freshly manufactured Corten Steel. At this stage the dark oily residue coats the Corten Steel.
  • Stage 2 – The oily residue is beginning to break down, as the Corten Steel begins to weather.
  • Stage 3 & 4 – The “Run-Off” stage – This can take around 3 to 9 months depending on weather and positioning.
  • Stage 5 & 6 – The final stages of the weathering process. Some “Run-Off” may still occur as the Corten Steels patina develops to a striking, more consistent appearance.

Corten Steel Run Off

During the weathering process, Corten Steel produces carbon run off or staining to adjacent materials such as stone or concrete. To reduce this possible staining, we recommend raising the product up off the ground by using a suitable stand, blocks of wood, slabs and such like; this will prevent any direct contact with the flooring material. After the initial reactive period, Corten Steel will cure and self-seal with little to no carbon run off. The weathering process of Corten Steel is integral to this product and as such we will not accept any responsibility for damage caused to surrounding materials as a result of carbon run off. Please ensure you do not place your product on any surface that may be damaged during the weathering process.

Corten can be easily cleaned using water and a soft brush. it can be sealed using a metal specific varnish, please note this will make the steel appear ‘wet’ or darker for the rest of the item’s life.

If Corten Steel is scratched or the weathered surface is damaged, it will re-weather (heal) to form a new skin to protect itself, making the damaged area nearly undisguisable.

The Initial Weathering Process
Upon receiving your Corten Steel garden feature, it will likely appear unweathered with a dark, oily residue. This is the first stage of the weathering process, which protects the steel during transportation and initial setup. 

Place the Corten garden feature outdoors in an open area where it can be exposed to the elements. The weathering process, where the steel forms a protective rust layer, typically takes between 3 to 9 months, depending on weather conditions. 

During the weathering period, avoid placing the feature on or near porous surfaces like stone or concrete to prevent staining from rust runoff.

Guidance on Sealing and Maintenance
Once the desired rust patina has developed, sealing the surface with paint conditioning and rust inhibitor oil is recommended to stabilise the rust layer and minimise further runoff. 

Our sealing oil recommendation: Owatrol Oil

This product penetrates through the rust to the sound metal below, isolating and protecting it from additional corrosion. You can apply Owatrol Oil using a brush or sprayer and allow it to dry for 12 hours, with a full cure taking up to 48 hours, depending on environmental conditions. This treatment not only enhances the durability of your Corten Steel garden feature but also maintains the integrity of its rustic appearance.

By following these simple steps, your Corten garden feature will achieve a beautifully weathered look while being well-protected for years of enjoyment in your garden.
