Natural Stone Tub MAGNUS

Often referred to as river stone tubs, our granite stone tubs are part of our best-selling collection. The Flumen tub, available in this collection, is crafted from natural river stone, adding a unique touch to any bathroom space. What distinguishes it is its finely finished edges, creating a lighter and more natural look. Each tub is meticulously crafted from a single piece of stone, without the use of glue, paint, or artificial adhesives. Our skilled craftsmen in Indonesia handle the cutting and draining process, ensuring precision and quality. With the ability to customize the size, shape, and shade according to your preferences, we source the stone directly from the quarry. This guarantees that we deliver the closest match to your desired boulder bath.
