Patented Egg-Shaped Artificial Stone Freestanding Bathtub – X-WGB04 | YUPURONG

Patented Stone Resin Freestanding Bathtub | Egg-Shaped – YUPURONG

The X-WGB04 is a design-patented egg-shaped freestanding bathtub handcrafted from solid-surface artificial stone (stone resin). Its continuous, seamless oval form and ultra-matte surface are engineered for high-end hotels, resorts and luxury residential bathrooms. Unlike acrylic or porcelain, our stone-resin blend retains water heat longer, is repairable if chipped, and never develops yellowing over time. Available in four lengths from 1500 mm to 1800 mm and three signature finishes — pure matte white, Carrara marble veining, and verdigris patina. YUPURONG supports OEM branding, custom finishes and project orders for importers, contractors and hospitality designers worldwide.

Protected Design PatentThis egg-shaped silhouette is registered under CNIPA Design Patent No. ZL 2024301261944. The organic oval form, tapered rim and seamless body are exclusive to YUPURONG. We supply this model to branded bathroom showrooms and hotel groups with full IP protection documentation available on request.

Why stone resin over acrylic or cast iron?

• Heat retention: dense mineral blend keeps water warm 2–3× longer than thin acrylic.

• Repairable: scratches and chips can be sanded and polished back to original.

• No water spots: matte porous-looking surface hides water marks, unlike glossy ceramic.

• Non-porous & hygienic: no glaze layer to crack; resists mold and limescale.

• Seamless form: the egg shape can only be achieved in molded stone — acrylic cannot hold this silhouette without visible weld lines.

Frequently asked questions about Stone Resin Bathtubs

1. What is an artificial stone bathtub? It is a solid-surface tub made from a mineral-resin composite (also called stone resin or engineered stone), cast in a mold and polished to a matte finish. It is heavier and denser than acrylic but warmer to touch than cast iron.

2. Do I need a special faucet for this freestanding tub? Yes. The X-WGB04 has no drilled faucet holes. It requires a floor-mounted bathtub filler (or a wall-mounted filler). We can supply matching floor-mount faucets on request.

3. What sizes are available? Four lengths: 1500, 1600, 1700 and 1800 mm. The 1500 mm model suits smaller master bathrooms; the 1800 mm is the hotel / villa flagship.

4. How much water does it hold? Approximately 180 L (1500) to 280 L (1800), depending on fill depth.

5. Is the finish customizable? Standard finishes are matte white, Carrara vein and verdigris patina. Custom RAL colors and special textures are available for project orders (MOQ applies).

6. What certifications do you provide? We are ISO 9001 certified. cUPC / CE / WaterMark testing documentation can be arranged for project bids and customs clearance on request.

7. Can the surface be repaired if scratched? Yes. Light scratches can be buffed with a fine polishing paste; deeper chips can be filled with matching resin and sanded — the tub will look new again.

8. How do I clean a matte stone bathtub? Use a mild pH-neutral cleaner and a soft cloth. Avoid abrasive scouring pads, bleach and aggressive descalers. Wiping dry after use prevents water marks.

9. What is the MOQ for export? 5 pcs for standard colors (mixed sizes allowed); 20 pcs for custom finishes. Sample orders are accepted within 15 days.

10. Do you supply for hotel and villa projects? Yes. We work with hospitality contractors, interior designers and importers. We can provide matching pedestal basins, consoles and fixtures to complete the bathroom suite.
