Batu candi
A dark volcanic stone popular for pool decks and wet areas because it feels natural, durable, and grippy underfoot when finished correctly.
Batu candi is a dark, porous volcanic stone (often described as lava stone). You see it on temples, modern villa facades, pool decks, stepping paths, feature walls, and bathrooms.
Its pores pull in water, which can help surfaces feel cooler underfoot in tropical heat—but that same porosity feeds moss and algae if cleaning slips. Many estates schedule periodic high-pressure washing alongside sensible sealing.
Quality varies by quarry, cut, sealing, and installation. If a listing highlights batu candi, still verify barefoot comfort, slip resistance when wet, and detailing at pool edges.
