Stone Bathtubs

Stone Bathtubs – Manufacturer of Solid Stone Freestanding Tubs for Homes, Hotels and SPA

Our stone bathtubs are handcrafted in Indonesia from single blocks of natural marble, granite, river boulder, onyx and petrified wood. For more than two decades we have focused exclusively on natural stone manufacturing, selecting only flawless boulders suitable for carving bathtubs. Every tub is shaped from one solid piece of rock – no glue, no bonding, no reconstruction.
Trusted by architects, developers and 5 star hotels in more than 57 countries, Lux4home™ delivers technical precision, strict multi stage quality control and reliable worldwide shipping for both residential and commercial stone bathtub projects.

Buying directly from Lux4home™ means you can discuss your bathtub with the people who make it. Start with the shape and natural colour you prefer, then explore each model’s dimensions, finishes and available size range. Choose an existing design or discuss a custom bathtub for your space. We help you establish which options are feasible for the selected stone, so you can make an informed choice before production.

Why Choose Lux4home™ Stone Bathtubs

Single block construction for maximum structural strength
Each stone bathtub is carved from one solid block rather than assembled from separate panels. Its walls and base therefore have no bonded panel joints on which watertightness depends. This avoids the risk of those assembly joints separating or leaking. Natural stone still needs careful selection, inspection, handling and support: single-block construction does not make it immune to natural fissures or damage.
Strict multi stage quality control
Every block is inspected for micro cracks, natural fissures, color inconsistencies and density before carving begins. Stones that fail our tests are rejected and never used for bathtub production. This process ensures long term durability under hot water exposure.
Expertise in difficult materials
We manufacture stone bathtubs from:
• river boulders (granite like density, ideal for indoor and outdoor use)
• cream and grey marble
• onyx (high translucency, requires precise carving)
• petrified wood (fossil material millions of years old)

Each material requires different cutting angles, polishing speeds and structural reinforcement techniques. Our artisans have more than 20 years of experience in handling these natural stones.
Thermal mass and heat retention
Natural stone has thermal mass: its walls absorb heat as the bath fills and store it as they warm. This is different from insulation. Water temperature also depends on the starting temperature of the stone, water volume, room conditions and the tub design. Plan the hot-water supply for the chosen model rather than assuming a fixed soaking time or a universal advantage over acrylic or metal.
Global installation experience
Lux4home™ stone bathtubs are installed in more than 200 hotels, resorts and residential developments. We regularly supply stone tubs for upper floor installations where weight distribution, subfloor reinforcement and access routing are required.
Verified manufacturer documentation
We provide material origin confirmation, production documentation, pre shipment inspection photos and videos, plus optional quality reports required by contractors and hotel chains.

Stone Bathtubs FAQ

Yes. Natural stone has extremely high density and compressive strength. When carved from a single block, a stone bathtub can last for decades with minimal maintenance. This makes natural stone tubs ideal for hotels, SPAs and high use environments.

Weight depends on the material and size.
Typical ranges:

Onyx bathtubs: 350–550 kg
Always verify load capacity with an architect for upper floor installations.

River Stone bathtubs: 600–1200 kg

Marble bathtubs: 400–700 kg

Stone absorbs and stores heat, but a cold bathtub also draws heat from the water as it warms. How long a bath stays warm depends on the stone and water temperatures, water volume, room conditions and tub design. Thermal mass is not the same as insulation, so there is no single cooling time or guaranteed advantage over every acrylic or metal bathtub.

Yes, provided the structural capacity is sufficient. Many hotels install our stone bathtubs on upper levels using reinforced subfloors or weight distribution platforms. We provide weight data and technical guidance for installers.

Absolutely. Nearly all of our production for architects and designers consists of custom models: round soaking tubs, oval freestanding tubs, rectangular baths or organic rock shaped tubs.

Every bathtub is secured inside a reinforced wooden crate with internal supports and shock absorbing materials. We ship globally via sea or air freight and support clients with unloading and access instructions.

Prices depend on the stone type, size and complexity of carving. Standard marble or granite tubs begin around 1900 USD, while rare materials such as petrified wood or crystal stone reach higher ranges. Contact us with your specifications to receive a manufacturer direct quote.

Plan your natural stone bathtub with the manufacturer

Once you have shortlisted a shape and colour, consider where and how the bathtub will be used. Our guide to stone bathtub weight and floor support explains the information needed for an upstairs installation. For an example of a completed project, see the Eclipse bathtub at Twinpalms Phuket. Discuss your preferred dimensions and installation conditions directly with our team before finalising your choice.
