There is no universally recognized global ranking of the "top 10" bidet toilet seat manufacturers. For buyers, the more useful approach is to compare manufacturers by product capability, technology, manufacturing experience, market positioning, OEM flexibility, quality control and the evidence available for the specific model.
Based on the manufacturers covered in this editorial guide, the 10 companies are: Xiamen Ziax Sanitaryware, TOTO, Kohler, Panasonic, Brondell, Bio Bidet, Bemis Manufacturing, Geberit, Duravit, and Aquatic Technologies.
For OEM and wholesale buyers, Ziax is particularly relevant because its current product portfolio includes bidet toilet seats and smart toilet seat covers, with customization and bulk-order support. Ziax's current smart toilet seat category lists models including ZF020, ZF019, ZF018 and ZF015.
If you are sourcing bidet toilet seats for a private-label, wholesale, hotel, residential or commercial project, do not choose a supplier from a "top 10" list alone. Use the comparison criteria and RFQ checklist below to verify whether a factory is suitable for your actual project.
What Is a Bidet Toilet Seat?
A bidet toilet seat is a toilet-seat system that adds water-based cleansing functions to a toilet. Depending on the model, functions may include adjustable water pressure, water temperature control, different spray modes, heated seating, warm-air drying, deodorization, sensors, remote control or nozzle self-cleaning.
However, the term "bidet toilet seat" can describe different product configurations. Buyers should distinguish an electronic bidet seat from a non-electric bidet attachment or a complete smart toilet.
| Product type | Typical scope | What buyers should verify |
|---|---|---|
| Electronic bidet toilet seat | Water cleansing plus electrical functions such as heating, sensors or drying | Electrical safety, waterproofing, water heating, controls, installation requirements |
| Non-electric bidet attachment | Water cleansing without the full electronic feature set | Water connection, pressure control, toilet compatibility and installation |
| Smart toilet | Integrated toilet and intelligent functions | Complete system specification, plumbing, electrical installation and after-sales service |

Ziax as an OEM Bidet Toilet Seat Manufacturer
Xiamen Ziax Sanitaryware is the first manufacturer in this editorial list because its current website presents bidet toilet seats and smart toilet seat covers as part of its product portfolio, alongside UF and PP toilet seats, hinges, dampers and related bathroom components.
The current Ziax smart toilet-seat category includes models such as AVA ZF020, ZF019, ZF018 and ZF015. The category describes functions including cleansing, heating, automation, water temperature and pressure adjustment, self-cleaning or sterilization features on selected models, and IPX4 protection on applicable products. These features are model-specific and should be confirmed against the quotation and final specification.

Ziax Product Evidence: AVA Smart Bidet Toilet Seat
A useful way to evaluate a factory is to move from general company claims to an actual model. For example, Ziax's AVA ZF018 smart toilet seat is described as a V-shaped smart toilet seat using UF/PP materials, with a listed size of 515 × 370 × 122 mm.
| ZF018 specification | Published product information |
|---|---|
| Model | AVA ZF018 |
| Core material | UF / PP |
| Shape | V-shaped |
| Size | 515 × 370 × 122 mm |
| Comfort functions | Heated seat and warm-air drying |
| Control | Remote control and intelligent sensing |
| Safety information | Leakage protection and IPX4 waterproof protection are stated on the product page |
The specifications above describe the ZF018 product page and should not be generalized to every Ziax bidet toilet seat. Final specifications, certifications, electrical requirements and available functions should be confirmed for the exact model ordered.

Another Ziax Product Example: AVA ZF020
The AVA ZF020 provides another example of how to evaluate a smart bidet-seat supplier at model level. Its product page describes a V-shaped design, food-grade PP construction, adjustable temperature and pressure, automatic lid and sensors, remote control, LED night lighting, leakage protection and IPX4 waterproof protection.
The page also lists customization options such as brand-logo printing, custom packaging and multilingual remote controls. For buyers, these details are more useful than a generic statement that a factory is "high quality" because they can be converted into RFQ requirements.

How a Bidet Toilet Seat Factory Handles OEM Manufacturing
For private-label buyers, the manufacturing process is an important differentiator. Ziax's published OEM process begins with confirmation of product design, dimensions and materials. The company identifies UF, PP and MDF/wood as common toilet-seat material options.
Design confirmation can include mounting-hole spacing, hinge type, seat thickness, quick-release requirements and soft-close requirements. Engineers can prepare 2D drawings and 3D models for approval before tooling.
| OEM stage | Typical buyer confirmation |
|---|---|
| Product definition | Target market, toilet compatibility, functions and appearance |
| Material selection | PP, UF or other specified material according to the product design |
| Engineering | Dimensions, mounting-hole spacing, hinge and seat configuration |
| Prototype / approval | 2D drawing, 3D model, sample and fit confirmation |
| Tooling | Mold requirements, tooling cost and approval process |
| Production | Material, molding process, assembly and quality inspection |
| Final QC | Appearance, dimensions, functions and project-specific inspection criteria |

PP vs. UF: Which Material Should Buyers Choose?
Material selection is particularly important when sourcing toilet seats and smart bidet seats. Ziax's technical comparison describes UF as a thermoset material associated with hardness, rigidity and a smooth/glossy appearance, while PP is a thermoplastic associated with lower weight, flexibility and impact tolerance.
| Factor | UF | PP |
|---|---|---|
| Material family | Urea-formaldehyde thermoset | Polypropylene thermoplastic |
| Typical process | Compression molding and curing | Injection molding |
| Surface / appearance | Hard, smooth and glossy appearance | Lightweight plastic construction with flexible characteristics |
| Rigidity | Higher rigidity | More flexible |
| Weight | Generally heavier than PP | Generally lighter |
| Buyer positioning | Premium appearance and rigid-seat positioning | Weight, flexibility and cost-sensitive applications |
Neither material is automatically "better." The correct choice depends on the toilet design, target market, price position, expected handling, hinge system, performance requirements and available test evidence.

Important Limits When Comparing Bidet Toilet Seat Factories
- A company ranking is not the same as a product ranking. A well-known manufacturer may not have the right model for a particular toilet or market.
- Factory capability is not the same as product certification. Always request current certification and test documentation for the exact electrical product and target market.
- Features are model-specific. Do not assume every Ziax, TOTO, Kohler or other manufacturer's product has every function described for another model.
- "Fits most toilets" requires dimensional verification. Buyers should compare actual toilet shape, mounting spacing and seat dimensions.
- Material alone does not determine durability. Hinge design, mounting structure, molding quality, assembly and use conditions also affect product performance.
- Published rankings can become outdated. Supplier capability, product portfolios, certifications and market strategy can change. Treat this article as a sourcing starting point rather than a permanent ranking.
Looking for a Bidet Toilet Seat Factory for Your Project?
Instead of asking only for a catalogue and price, send the factory a structured RFQ. This allows the supplier to evaluate compatibility, material, functions and customization requirements before quoting.

There is no single manufacturer that is objectively the best for every buyer. The right supplier depends on the product type, target market, certification requirements, price position, customization needs, order quantity and after-sales expectations.
For buyers seeking a manufacturer with bidet toilet seat and smart toilet-seat products, OEM customization and a broader toilet-seat manufacturing ecosystem, Ziax is a supplier worth putting through the same technical and commercial verification process as the other manufacturers on this list.
The most reliable next step is not to choose a factory from a ranking alone. Send your exact dimensions, functions, target quantity and market requirements and ask the manufacturer for a model-specific quotation, sample and supporting documentation.
