Sukabumi stone: what it is, where it comes from and what it brings to a pool

Sukabumi stone is a green natural stone quarried in the Sukabumi region of West Java, Indonesia. In Spain it is often called “Bali stone” because it became popular in the pools of Balinese villas and hotels, although it comes from Java.

What it is and how it is supplied

Origin

Sukabumi region, West Java (Indonesia).

Colour

Green, with natural variation between pieces and batches.

Finishes

Natural (sawn cut, semi-smooth surface) and textured (surface with relief).

Formats

10×10, 20×10 and 20×20 cm, approximately 1 cm thick.

What it brings to a pool

• A turquoise-green reflection in the water. Intensity depends on light, depth and water treatment.
• A mineral surface with tonal variation, far from the uniform look of glass mosaic or liner.
• Two finishes to solve both the pool shell and the surrounds with the same material.
• Small formats that adapt to steps, benches and curved shapes.

Claims worth checking

Some very optimistic descriptions of this stone circulate online. We removed these from our site because we have no documentation to support them:

• “It purifies water thanks to zeolite”: we have no analysis proving it. The pool still needs its usual water treatment.
• “It is non-slip”: slip resistance is measured by testing and depends on the finish. In Spain, the building code (CTE) requires class 3 in barefoot areas and in pool floors up to 1.50 m deep. Ask for the documentation of the specific finish.
• “It lasts for decades”: durability depends on installation, setting materials, sealing and maintenance.

Quick recommendation

Natural finish for the inside of the pool, because it is easy to clean and enhances the colour of the water. Textured finish for copings, surrounds and outdoor steps, after checking the regulatory requirements of your project.
