In the competitive landscape of bathroom fixtures, success often hinges on a manufacturer’s ability to iterate based on direct consumer feedback. Recently, Сантехника HanYu partnered with a leading vessel sink wholesaler in Brazil to solve a specific market gap: the demand for versatile, space-saving vessel sinks with integrated faucet mounting.
The Challenge: Adding Functionality to Proven Designs
Our client already had two top-selling vessel sinks in the Brazilian market. However, they identified a growing trend—consumers were requesting the same aesthetic but with integrated faucet holes.
The goal was to modify these existing designs to allow for direct faucet installation on the basin itself, rather than requiring wall-mounted or deck-mounted tall faucets.
Existing Designs




The HanYu Solution: Technical Precision & OEM Flexibility
To meet this request, our engineering team executed a comprehensive product development plan:
- Feasibility & Design: We evaluated the structural integrity of the existing shapes to ensure adding a faucet ledge wouldn’t compromise the ceramic’s durability. We provided detailed technical drawings and multi-angle 3D renderings for client approval.
- Precision Mold Customization: New vessel sink molds were developed to ensure the faucet holes were perfectly centered and reinforced.
- Aesthetic Versatility: To cater to diverse interior styles, we manufactured the basins in multiple finishes:
- High-Gloss & Matte White
- Custom Marble Textures (Glazed)
- Structural Adjustments: The rear of the basin was redesigned to be perfectly flat for flush-to-wall installation, optimizing space for smaller Brazilian bathrooms.




Quality Control & Project Outcomes
Manufacturing high-quality ceramic vessel sinks requires strict deformation control, especially for flat-back and rectangular designs.
- Technical Excellence: Our team maintained strict tolerances to ensure the “flat back” remained perfectly level and the rectangular edges stayed sharp without warping during the high-temperature firing process.
- Delivery: We successfully delivered 800+ pieces per model in the first batch.
- Market Impact: The first sample batch met all sales requirements on the first attempt, leading to immediate market success. The client is currently negotiating their next reorder.
