China remains an important sourcing base for freestanding bathtubs, engineered-stone bathroom products, vanity units, and complete bathroom collections. For overseas buyers, its advantage is not simply lower unit cost: it is the ability to combine mold development, surface finishing, packaging adaptation, private labeling, and export logistics within one supply chain.
However, marble bathtub can be a hand-carved natural-marble tub, a stone-resin tub with mineral filler, or a solid-surface tub with a marble-like appearance. These products differ substantially in weight, porosity, repairability, installation requirements, lead time, and export risk.
The global marble market was valued at USD 73.03 billion in 2025 and is projected to reach USD 75.98 billion in 2026. Building and construction represents the largest application segment, while Asia-Pacific accounted for 30.8% of global market value in 2025. This broader demand for premium, durable architectural materials continues to support marble-look bathroom projects, hotels, villas, and residential renovations.
This list is designed for importers seeking repeatable supply rather than one-off retail purchases. Suppliers were screened based on publicly visible product relevance and the following commercial criteria:
- Material capability: Ability to clearly identify whether the tub is natural stone, cast stone resin, acrylic solid surface, or another composite.
- Customization depth: Flexibility for dimensions, drain position, overflow configuration, finish, color, logo, packaging, and matching basins or vanities.
- Manufacturing evidence: Product specialization, factory information, production process visibility, or established export-facing operations.
- Quality-control discipline: Incoming material checks, mold inspection, curing control, surface finishing, water-retention testing, dimensional inspection, and final packaging inspection.
- Export readiness: Experience with overseas markets, project documentation, port accessibility, shipping protection, and communication speed.
- Compliance documentation: Ability to provide product-specific declarations, laboratory reports, and valid management-system certificates where required by the destination market.
A supplier should not be shortlisted only because it displays a CE logo. For products covered by the EU Construction Products Regulation, CE marking is linked to declared product performance and applicable harmonised technical specifications; buyers should request the related Declaration of Performance rather than relying on a logo printed in a catalog.
China's bathtub supply chain is concentrated in several regions, each with different strengths:
| Cluster | Typical strength | Suitable sourcing need |
|---|---|---|
| Guangdong: Foshan, Guangzhou, Shenzhen, Huizhou | Sanitary ware assembly, molds, solid surface, shower products, export services | Private-label collections, hotel projects, mixed bathroom categories |
| Zhejiang: Jiaxing, Pinghu, Ningbo area | Export-oriented home products, bathroom furniture, integrated supply, port access | Brand development, flexible OEM, small-to-mid-volume programs |
| Fujian: Xiamen, Quanzhou | Natural stone, slabs, fabrication, stone furniture and architectural projects | Natural marble, carved stone, matching stone vanity programs |
| Hebei: Quyang, Baoding area | Stone carving, sculpture, decorative architectural stone | Statement natural-stone tubs and bespoke carved pieces |
| Shandong: Qingdao area | Broad bathroom-product supply and northern export logistics | Multi-material bathtub sourcing and consolidated procurement |
For buyers of genuine natural-marble tubs, Fujian and Hebei are usually the more relevant starting points because of their stone-fabrication ecosystems. For stone-resin or solid-surface bathtubs, Guangdong and Zhejiang offer stronger options for repeatable molds, contemporary shapes, coordinated bathroom collections, and OEM branding.
The following companies are presented in alphabetical or practical sourcing order, not as a claimed audited ranking. Buyers should request a current factory audit, legal registration, product test reports, and sample approval before placing production orders.
| Supplier | Location | Primary relevance | Publicly stated establishment | Capacity / MOQ | Publicly indicated compliance or capability |
|---|---|---|---|---|---|
| Jiaxing Miluo Smart Home Co., Ltd. | Jiaxing, Zhejiang | Stone-resin, solid surface, marble-look bathtubs and complete bathroom collections | 1999; Miluo brand launched in 2005 | Quote-based; verify by model and customization | Customized bathroom solutions; quality-control and sustainability commitments stated |
| KingKonree International China Surface Industrial Co., Ltd. | Shenzhen / Huizhou, Guangdong | Solid-surface and stone-resin tubs | 2000 | 25,000 m² facility stated; MOQ to confirm | CE, SGS, cUPC, CSA and Prop 65 claims shown publicly; request product-specific documents |

Jiaxing Miluo Smart Home Co., Ltd. is a Zhejiang-based manufacturer established in 1999, with the Miluo brand launched in 2005. The company focuses on customized contemporary bathroom products, including solid-surface, resin-stone, marble-look bathtubs, basins, vanities, shower bases, and mirrors. Its location in Pinghu, close to both Shanghai Port and Ningbo Port, can simplify export planning for customers shipping to North America, Europe, Australia, the Middle East, and other international markets.
Miluo is particularly relevant for emerging brands, regional wholesalers, boutique hotel programs, and buyers that need a coordinated bathroom collection rather than a single tub SKU. Its stated approach covers concept development through production and after-sales communication, making it a practical candidate for projects requiring close sampling feedback, customized dimensions, finish selection, drainage adjustments, branded cartons, and mixed-container orders.
OEM/ODM suitability:
- Custom freestanding bathtub dimensions and profiles
- Matte, gloss, white, gray, black, and dual-tone surface options
- Coordinated basins, vanities, shower bases, mirrors, and bathroom packages
- Responsive development support for small and medium-sized brands
- Export-oriented communication and post-delivery follow-up
Due-diligence questions: Ask for the current factory audit, monthly output by material family, mold ownership terms, warranty policy, sample lead time, and inspection checklist for each bathtub model.
KingKonree is a solid-surface and stone-resin manufacturer established in 2000. Its public materials indicate more than 80 solid-surface bathtub styles, a 25,000 m² facility in Huizhou, and shipment experience across 126 countries. The company reports solid-surface bathtubs, basins, countertops, and sheet materials, making it suitable for buyers seeking a standardized collection with customization options.
For procurement teams, KingKonree's strength is its category concentration in mineral-filled, non-porous, stone-like bathroom products rather than hand-carved natural marble. This can be preferable for projects where weight control, consistent color, repairability, and repeatability matter more than natural veining.
OEM/ODM suitability:
- Standard mold selection with customized sizes or finishes
- Stone-resin and solid-surface bathtubs
- Matching washbasins, shelves, countertops, and shower components
- Hospitality, residential development, and distributor programs
KingKonree publicly lists CE, SGS, cUPC, CSA, and Proposition 65-related credentials. Buyers should still request the certificate number, issuing body, covered product model, report date, scope, and any applicable destination-market documentation before using these credentials in a tender or customs file.
Guangzhou Liangjing Bathroom Equipment is listed with bathtubs, acrylic sheets, vanity tops, and solid-surface products. This product mix may be useful for buyers developing a collection that includes acrylic, engineered-stone, and vanity-top categories under one supplier relationship.
The reviewed public listing does not provide a verifiable founding year, factory area, monthly output, MOQ, or certificate scope. It should therefore be treated as a qualification candidate rather than a fully verified production partner.
OEM/ODM suitability:
- Bathtub and vanity-top coordination
- Material comparison between acrylic and solid-surface options
- Potential collection development for bathroom distributors
Verification priority: Confirm whether the company owns production lines or coordinates external production; request a live factory video walkthrough showing molding, sanding, polishing, inspection, and packing.
Foshan Nanhai Dewo Sanitary Ware is listed in Foshan with bathtubs, massage bathtubs, shower enclosures, shower rooms, and related bathroom equipment. Foshan's broad bathroom ecosystem may be advantageous when a buyer needs to consolidate several bathroom categories, rather than sourcing a bathtub alone.
Its publicly visible listing indicates product relevance but does not establish current annual capacity, founding year, or valid certification status. For a marble-look or solid-surface bathtub program, ask whether the material is cast stone resin, acrylic composite, or another formulation.
OEM/ODM suitability:
- Bathroom-category consolidation
- Freestanding and massage-bathtub product development
- Shower enclosure and bathtub project combinations
Shenzhen MSUN is listed with solid-surface sheets, solid-surface washbasins, solid-surface bathtubs, worktops, and Corian-type material applications. This makes it potentially relevant for commercial interior projects where a tub must match vanity tops, basins, and wall surfaces.
The product category suggests a solid-surface focus rather than a quarry-to-bathtub natural-marble model. It is worth considering when material consistency across bathroom elements is more important than the singular veining of natural stone.
OEM/ODM suitability:
- Solid-surface tubs and matching basin/worktop programs
- Custom color matching
- Commercial washroom and hospitality applications
Shenzhen Eshine is listed with solid-surface sheets, quartz stone, bathtubs and washbasins, kitchen countertops, and bathroom vanity tops. Its cross-category material range may suit buyers planning coordinated surface applications across kitchens and bathrooms.
Because the listing alone does not confirm whether a particular "marble bathtub" is natural stone, quartz composite, or solid surface, buyers should request a material formulation sheet and cross-section photographs before comparing quotations.
OEM/ODM suitability:
- Bathtub, basin, countertop, and vanity-top coordination
- Quartz- or stone-look surface concepts
- Private-label collections requiring multiple product categories
Guangzhou Sarhang Stone Solutions is listed with marble, granite, onyx, limestone, and travertine products. It is more relevant to buyers seeking genuine stone sourcing, slab selection, or natural-stone fabrication than to buyers seeking mass-produced cast-stone tubs.
Natural-marble tubs require specialized hollowing, structural thickness control, drain machining, crack inspection, and export crating. Before proceeding, confirm that the supplier fabricates bathtubs in-house and can provide completed-project photos rather than only slab or tile references.
OEM/ODM suitability:
- Natural-marble material selection
- Vein-bookmatching and custom block selection
- Bespoke villa, showroom, and luxury hospitality projects
Xiamen TSP Stone Industry is listed with marble, marble slabs, granite, granite slabs, and granite tiles. Xiamen is a major export-oriented stone-processing area, so this type of supplier may be valuable when procurement requires natural-stone selection and project-specific fabrication.
It should be qualified carefully for bathtub production because slab fabrication is not equivalent to producing a safe, drain-ready, water-bearing tub. A suitable supplier should demonstrate cavity machining, wall-thickness control, stress-crack inspection, sealing treatment, and wood-crate design.
OEM/ODM suitability:
- Genuine marble or granite bathtub projects
- Stone vanity, wall cladding, and bathtub matching
- High-value, low-volume custom orders
Quanzhou Tianyuan Stone is listed with granite, marble tiles and slabs, countertops, vanity tables, slate, sandstone, pebble, and travertine. Its product range indicates relevance for comprehensive natural-stone bathroom projects, particularly where tubs need to coordinate with vanity tops and wall finishes.
For procurement, do not assume a stone countertop manufacturer can safely deliver a bathtub. Require a sample section or full pre-production sample, water-fill test records, dimensional drawings, and crate drop-protection details.
OEM/ODM suitability:
- Natural-stone bathroom packages
- Custom vanity-and-bathtub coordination
- Project-based stone fabrication
Qu Yang Sheng Ya Sculpture Factory is listed with stone sculpture, marble fireplaces, marble fountains, statues, planters, and OEM/ODM capabilities. As Quyang is associated with stone carving, this supplier type can be relevant for highly sculptural, hand-finished, natural-marble tubs that standard sanitary-ware factories may not produce.
The commercial risk is that artistic stone carving and bathroom manufacturing are different disciplines. The buyer must validate drainage engineering, base flatness, sealing, installation instructions, waterproof packing, and export experience for bathtub-sized stone products.
OEM/ODM suitability:
- Sculptural natural-marble tubs
- Boutique hotels, villas, spa suites, and showrooms
- Hand-carved, low-volume statement pieces
| Factor | Natural marble bathtub | Stone-resin / solid-surface bathtub |
|---|---|---|
| Main composition | Natural quarried stone | Mineral filler plus resin binder or acrylic resin system |
| Appearance | One-of-a-kind veining and color variation | More consistent appearance; marble-like effects can be controlled |
| Weight | Very high; often requires structural and handling planning | Heavy but generally more manageable than solid natural stone |
| Porosity | Requires correct sealing and maintenance | Often lower porosity when properly manufactured |
| Repair | Professional stone repair may be needed | Minor scratches may often be refinished, depending on construction |
| MOQ | Frequently project-based | Often more flexible when existing molds are used |
| Typical risk | Cracks, hidden fissures, staining, inconsistent block quality | Low mineral loading, uneven curing, thin walls, color inconsistency |
- A full material declaration identifying resin type, mineral filler, pigment system, coating, and wall construction.
- Unit weight and packed weight for every model.
- Dimensioned technical drawing showing drain center, overflow location, base footprint, and recommended installation clearance.
- Water-retention test evidence for every new mold or first production batch.
- Finish standard: gloss level, color tolerance, allowable pinholes, sanding marks, edge consistency, and repair acceptance criteria.
- Packaging drawing showing foam density, edge protectors, crate material, pallet dimensions, and container-loading plan.
- A retained golden sample signed by both parties before mass production.
The most overlooked risk is not the visible surface—it is the hidden underside and drain-zone construction.
A bathtub can look flawless under showroom lighting while having insufficient reinforcement, uneven wall thickness, weak support around the drain, or an unstable base. These problems may only appear after the tub is filled with water and occupied. For natural stone, micro-fissures can also be concealed by polishing, filling compounds, or veining patterns.
To reduce this risk, include these requirements in the purchase order:
1. Require underside photographs before packing, not only top-view beauty shots.
2. Define minimum wall thickness and tolerances on the approved drawing.
3. Request a filled-water test photo or video with the serial number visible.
4. Specify that drain-hole machining, overflow drilling, and base leveling are inspected before final packaging.
5. Retain one approved production sample for color, finish, drain placement, and surface quality comparison.
This simple control point can prevent costly claims after containers arrive at a warehouse or project site.
Request the Chinese business license, unified social credit code, bank-account name, factory address, and export entity. The contracting entity, payment beneficiary, and manufacturer should be clearly explained if they are not the same company.
Do not purchase based on the name "marble bathtub" alone. State clearly in the RFQ whether you require:
- Genuine natural marble
- Cast stone resin
- Acrylic solid surface
- Quartz composite
- Gel-coat stone resin
- Marble-pattern acrylic or other decorative finish
A remote or on-site audit should verify:
- Mold storage and ownership control
- Mixing, casting, curing, sanding, polishing, and repair areas
- Dust extraction and worker protection
- In-process and final inspection stations
- Water testing and drainage checks
- Packaging and loading practices
- Traceability from raw material batch to finished product
For standard products, request one finished sample. For custom products, approve the following in sequence:
1. Dimensioned drawing
2. 3D rendering or technical model
3. Material chip or color panel
4. Prototype or first article
5. Signed golden sample
6. Pre-shipment inspection standard
Do not approve only from digital renderings, especially for marble-look colors and matte finishes.
Natural-marble tubs can be extremely heavy. Confirm floor-loading limits, crate dimensions, forklift requirements, unloading method, installation route, door openings, and bathroom structural capacity before shipment.
For container shipments, ask for:
- Gross weight per crate
- Crate dimensions
- Container loading plan
- Moisture protection method
- Spare parts carton details
- Insurance recommendation
- Replacement policy for transit damage
The right China marble bathtub supplier depends on the product you are actually buying. Choose a stone specialist for genuine natural-marble statement tubs, a solid-surface manufacturer for consistent repeat production, and an integrated bathroom supplier when your brand requires coordinated tubs, basins, vanities, shower bases, and mirrors.
For brands, wholesalers, and project buyers seeking flexible customization and coordinated contemporary bathroom products, Jiaxing Miluo Smart Home Co., Ltd. is a practical supplier to include in the RFQ stage. Its Zhejiang location, proximity to Shanghai and Ningbo ports, customized bathroom-product focus, and communication-oriented development model make it particularly suitable for small-to-mid-sized private-label programs and long-term collection building.
Send a detailed RFQ with your target material, drawings, destination market, certification requirements, annual forecast, expected order quantity, packaging expectations, and target delivery date. The quality of the supplier's reply will often reveal more than a polished catalog.
Ask for the full certificate, certificate number, issuing certification body, scope, factory address, issue date, expiry date, and surveillance status. Then check the certification body's public directory or contact it directly. Confirm that the listed scope covers sanitary ware or relevant manufacturing activities, not only trading or unrelated products.
Not automatically in the same way for every product and every market scenario. The applicable rules depend on the product type, intended use, and whether it is covered by a harmonised standard or European Technical Assessment. If CE marking applies, request the Declaration of Performance, product identification, applicable standard, and supporting documentation. Do not accept a logo alone as proof.
Ask for a cut-edge photo, material declaration, product weight, density information, and manufacturing-process explanation. Natural marble should show continuous mineral structure through the cross-section, while stone resin normally shows mineral filler embedded in a resin matrix. If the supplier refuses to provide this information, treat the material claim as unverified.
MOQ depends on the product type. Existing molds for solid-surface or stone-resin tubs may allow lower trial quantities, while a new mold requires development cost and higher volume commitment. Natural-marble tubs are often quoted per piece or per project because each block, vein, and carving requirement can differ. Ask separately for MOQ, sample charge, mold fee, and repeat-order pricing.
Inspect the approved product against the signed golden sample, then verify dimensions, drain position, overflow position, base stability, surface defects, color consistency, water retention, packaging strength, carton/crate labeling, and spare-part completeness. For natural stone, include crack, fissure, fill, and sealing inspections.
