Eco Friendly Non Electric Smart Bidet Toilet – Model 157-9249
The 157-9249 sets a new standard in sustainable bathroom design with its eco-friendly, non-electric smart bidet system. Featuring a hygienic self-cleaning nozzle and ultra-low water consumption, this toilet delivers premium performance while minimizing environmental impact. Ideal for green building projects and environmentally conscious buyers.
Key Features & Benefits
- Zero Electricity Operation – All bidet functions operate purely on water pressure. No wiring, no batteries, no power consumption. Perfect for remote locations and cost-sensitive projects.
- Hygienic Self-Cleaning Nozzle – The advanced self-cleaning mechanism automatically rinses the nozzle with fresh water before and after each use, eliminating 99.9% of bacteria without chemical agents.
- Eco-Friendly Dual Flush – Intelligent dual-flush technology uses only 3.0L for liquid waste and 4.8L for solid waste, reducing water consumption by up to 40% compared to conventional toilets.
- Water-Saving Jet Siphon – The precision-engineered jet siphon system maximizes flushing power while minimizing water usage, meeting WaterSense and international water efficiency standards.
- Soft-Close Quick-Release Seat – Ergonomically designed seat with slow-close hinges eliminates slamming noise. Quick-release mechanism allows easy cleaning and maintenance.
- Anti-Bacterial Glaze Surface – The vitreous china surface is treated with a nano-silver anti-bacterial glaze that inhibits 99.9% of bacterial growth, keeping the bowl cleaner for longer.
- Universal Rough-In Compatibility – Standard 305mm rough-in design fits most residential and commercial bathroom layouts worldwide, simplifying specification for large-scale projects.
The Science of Vitreous China
At Yingjie, every toilet begins with premium vitreous china - a material perfected through centuries of ceramic engineering. Our vitreous china undergoes a rigorous triple-firing process, reaching a peak temperature of 1280°C. This extreme heat vitrifies the clay body, transforming it into a dense, non-porous, glass-like structure with exceptional strength and durability.
Figure 1: Vitreous china fired at 1280°C achieves complete vitrification for maximum density.
The 1280°C firing temperature is critical: at this threshold, silica particles fully fuse, creating a body with water absorption below 0.5% - far exceeding the ISO 10545-3 standard. This near-zero porosity means the toilet body will never absorb moisture, odors, or stains, maintaining its pristine appearance for decades.
Triple-Layer Glazing Process: Our proprietary glazing technique applies three distinct layers: a base engobe for adhesion, a mid-layer for color depth, and a top nano-glaze for surface hardness. Each layer is fired separately, resulting in a finish that resists scratches, chemical cleaners, and UV degradation. The fully glazed trapway ensures smooth waste evacuation - no rough surfaces for debris to cling to.

Vacuum Testing Protocol: Every 157-9249 unit undergoes a rigorous vacuum test at 0.08 MPa negative pressure before leaving the factory. This process instantly reveals any micro-porosity or structural flaw - only units that maintain perfect vacuum seal are approved for shipment.
Figure 3: Each unit is vacuum-tested to guarantee zero-defect ceramic integrity.
Compared to ceramic alternatives fired at lower temperatures, vitreous china at 1280°C offers 40% greater flexural strength, 3x better stain resistance, and a lifespan exceeding 30 years under normal use. It is the material of choice for architects and designers specifying high-traffic commercial restrooms and luxury residential projects alike.

B2B FAQ
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 50 units per model for the first trial order. For subsequent orders, we can accommodate mixed-container shipments with as few as 10 units per SKU.
Q: What is the delivery lead time?
A: Standard production lead time is 25–30 days from order confirmation. For urgent projects, we offer expedited production at 15–20 days with a small surcharge.
Q: Does this toilet require electricity?
A: No. The 157-9249 is a fully mechanical non-electric smart toilet. All bidet functions operate purely on water pressure. This makes it ideal for regions with unstable power supply or projects prioritizing energy efficiency.
Q: Do you support engineering and large-scale projects?
A: Yes. We provide dedicated project support including custom packaging, palletization, technical data sheets, installation guides, and on-site training for bulk orders exceeding 200 units. Our engineering team can assist with specification compliance for LEED, BREEAM, and Green Building certifications.
Q: What certifications does this product hold?
A: The 157-9249 is certified to ISO 9001, CE, WaterMark, and CUPC standards. Additional regional certifications (SASO, SONCAP) are available upon request for specific markets.
Q: Can you provide OEM/ODM services?
A: Absolutely. We offer full OEM customization including logo printing on the ceramic body and seat, custom color matching (12 standard colors available), and packaging design. Minimum order for OEM is 100 units.
