Product Detail
Red Sandalwood Marble Sinks, Bathtubs & Vessel Basinssins
Red Sandalwood (紫檀金沙) is a natural marble quarried in China, prized for its distinctive blend of overlapping purple tones with diagonal light grey bold stripe veins that resemble natural wood grain. The stone's steadfast, historical temperament makes it a favourite for Traditional Chinese, European Classic, and Neo-Classical bathroom and spa interiors where warmth and character matter as much as function. Apexstone carves each sink, bathtub, and vessel basin from solid Red Sandalwood marble blocks at our Shuitou factory, combining traditional hand-carving with 5-axis CNC precision for boutique hotel bathrooms, spa installations, and high-end residential master suites.tes.

The Wood-Grain Marble: Why Red Sandalwood Is Different
Most marbles are defined by their veining pattern, but Red Sandalwood is defined by its texture. The diagonal light grey bold stripe veins run across a blend of overlapping purple tones, creating a surface that looks less like stone and more like polished exotic wood. This wood-grain character makes Red Sandalwood sinks and bathtubs uniquely suited for bathroom designs that seek warmth without sacrificing the durability and water resistance of natural marble.
Red Sandalwood marble has a density of 2.6-2.8 g/cm³, water absorption below 0.5%, and Mohs hardness of 3-4. The fine-grained crystalline structure accepts a high-gloss polish that deepens the purple tones and amplifies the wood-grain vein contrast. When sealed properly, the stone performs well in continuous-moisture bathroom environments.

Solid Stone Bathtubs
Freestanding bathtubs carved from a single Red Sandalwood marble block. The purple base with wood-grain veining creates a warm, organic surface that no engineered material can replicate. The stone's natural thermal mass retains heat longer than acrylic or fiberglass tubs, making it ideal for spa-like soaking experiences. Available in oval, rectangular, and custom sculptural forms.rms.

Solid Stone Vessel Sinks - Carved from Whole Blocks
These are not thin slab sinks cut from a slab - each vessel sink below is carved from a whole, solid Red Sandalwood marble block. The 5-axis CNC router hollows the basin interior while preserving the natural wood-grain vein pattern on the exterior. The result is a monolithic stone basin where the purple tones and diagonal stripe veining flow continuously around the entire form, with no joints, seams, or slab cuts. Available in round, square, and organic freeform shapes.

Bathroom Vanity Tops with Integrated Sinks
