Onyx Bathtubs – Hand-Carved Translucent Stone Tubs for Luxury Interiors

Discover the striking beauty of natural onyx bathtubs, handcrafted in Indonesia from single blocks of semi-precious stone. Unlike reconstructed or resin-filled tubs, each Lux4home™ onyx bathtub is carved from a solid, flawless boulder - ensuring uninterrupted light transmission, structural integrity and exceptional visual depth.
Onyx is naturally translucent. When illuminated, it reveals warm amber tones and crystalline veins, creating a glowing centerpiece for luxury homes, spas and 5-star hotels. With over 20 years of experience, Lux4home™ remains one of the few manufacturers capable of producing large, structurally stable, backlit-ready onyx tubs and exporting them safely worldwide.
Our collection includes Yellow Onyx, Honey Onyx and Sunset Onyx — each selected manually to avoid internal cracks and guarantee long-term durability.

Why Choose Lux4home™ Onyx Bathtubs?

True Translucency (Illumination Ready)
Onyx is the only natural stone bathtub that can be backlit. Because our tubs are carved from single blocks, without glue or fillers, light passes smoothly through the stone’s crystalline structure. When fitted with LED lighting, the entire bathtub glows - a dramatic effect impossible to achieve with marble or granite.
Single-Block Integrity
Many onyx tubs on the market are assembled from smaller pieces, which results in visible seams and weak areas. When illuminated, these seams appear as dark, broken lines. Lux4home™ uses only whole, flawless blocks to ensure perfect light diffusion and long-term structural strength.
Strict Stone Selection (No Micro-Cracks)
Onyx is naturally sensitive during carving. We reject any boulder with internal fractures. Only high-density blocks are approved, guaranteeing stability for everyday use in hotels and private residences.
Perfect Thermal Comfort
Onyx absorbs heat and slowly releases it, allowing long, relaxing soaks. Once warmed, the stone remains pleasantly warm to the touch.

Onyx Bathtubs FAQ

Yes. Natural onyx is translucent and allows light to pass through its crystalline structure. With LED panels installed behind or underneath the tub, the entire vessel glows. This effect is only possible with solid-block onyx without resin or glue.

Yes - when carved from a high-density, flawless block. Cracking occurs primarily in multi-piece tubs or stones with hidden fractures. Lux4home™ eliminates these through strict selection and multi-stage inspection.

Onyx is a semi-precious stone and more sensitive than granite. We deliver tubs pre-sealed, but acidic cleaners (e.g. vinegar, hair dyes, descalers) should be avoided. Clean with pH-neutral soap to maintain its jewel-like clarity.

Depending on shape and dimensions, an onyx tub typically weighs 450–850 kg. For upper-floor installations, structural consultation is recommended.

Onyx is a rare stone with high translucency, difficult extraction and a high rejection rate during production. Only a small percentage of raw blocks are suitable for carving a seamless bathtub — this rarity defines its value.

Yes. Because onyx is vibration-sensitive, each tub is packed in a foam-lined, reinforced wooden crate. We have successfully delivered onyx tubs to the USA, UK, EU, Middle East and Australia.
