The Problem with “Standard”

OEM cultured marble vanity tops provide the perfect solution for developers and designers seeking flexibility beyond standard products. Finding the right vanity top for a large-scale hospitality project or residential development can be a frustrating problem. Standard catalogue dimensions are almost right, but not perfect, and the basin shapes are often common. Your unique design vision is forced to fit a standard product.

This compromise can lead to installation challenges and a final product that fails to stand out.

This is why a true OEM (Original Equipment Manufacturer) partnership is the solution. At Vina PolyStone, we have built a clear, 4-step manufacturing process designed specifically to solve this challenge and build your unique product at scale.


The 4-Step OEM/Private Label Process

Stage 1: Technical Consultation & Design Plan

The process begins with a detailed technical consultation. Our engineering team works directly with you to create a precise technical plan, ensuring your idea can be built correctly before production begins.

This stage applies our deep customization skills. We offer true design freedom, with capabilities that include:

  • Exact Custom Dimensions: We build to your precise measurements (e.g., 31.5-inch) to fit your architectural plans perfectly.
  • Unique Basin Shapes: We create exclusive molds for your special collections.
  • Specific Sink Placements: We configure sinks exactly where you need them: left, right, or center.

By confirming all technical details first, we help you save time and prevent costly errors.

Stage 2: Custom Mold Development

After you approve the technical plan, we begin crafting the most important part of a Custom OEM Project: your exclusive mold.

Developing these molds in-house is a proven skill, a capability validated by our partners. As an example, a new client in the United States recently committed a deposit for our team to develop a custom mold for their project. This process gives you a unique product that no one else has, securing a strong competitive advantage for your brand.

Stage 3: Sample Production & Quality Approval

Next, we produce a complete sample for your approval. This sample is not just a model; it is a finished product that must pass our complete Quality Control (QC) tests before we send it to you.

Our QC process includes: 

  • Mechanical Testing: To confirm strength for a long life in high-traffic areas.
  • Stain Resistance Testing: To protect the surface against common bathroom products.
  • Measurement & Visual Inspection: To ensure every detail matches the approved design.

You can then approve a production-ready product with confidence, knowing all future pieces will have this same high quality.

Stage 4: Mass Production & Global Delivery

After your final approval, mass production begins. This stage is supported by the industrial strength of Nhat Huy Group, which provides the foundation for our reliability.

This backing ensures a large-scale factory, over 20 years of manufacturing experience, and a Closed-Loop Supply Chain to control material quality and cost. The result for you is consistent quality on every order and reliable Global Supply to over 60 countries, ensuring your project stays on schedule.

Closed-Loop Supply Chain
