Quartz Countertop GQ2026048 – Frost White Hotel Project Made in Thailand

Project Overview

This is a custom quartz countertop project for bathroom spaces in a high-end hotel chain in the United States. The core material is 20mm thick pure white quartz with a fine, shimmering pattern. The countertops are custom-made with sink cutouts and pre-drilled holes for fixtures. They are designed to meet the standard requirements for North American hotel bathroom renovations. The finished products are shipped to a B2B construction contractor client in the US.

Project Details

Design Pattern and Suitability for the Space

The project uses pure white quartz with a fine shimmer, produced locally in Thailand. The slab has a clean, off-white base. Tiny, sparkling particles are evenly distributed across the surface. Light passing over the surface creates a soft, dynamic glow. This gives the material a high-end, transparent look. The minimalist yet detailed texture perfectly matches the modern, simple, and subtly luxurious style of hotel bathrooms. It brightens the space and creates a clean, relaxing atmosphere.

Standardized Mass Customization Processing

This project involves manufacturing over 100 countertops for a hotel chain. It relies on CNC automated production lines. The process ensures precise cutting and shaping for countertops of a uniform size (1200mm x 550mm x 20mm). Hundreds of units per batch have identical dimensions, cutout positions, and edge finishes. Machining tolerances are strictly kept within ±0.5mm. This ensures highly consistent installation results across all hotel bathrooms. It also improves on-site installation efficiency and shortens the project delivery time.

Custom Cutouts and Pre-drilled Fixture Holes

Sink cutouts are made precisely according to the provided American under-mount sink model specifications. There are two cutout types: a square cutout (450mm x 350mm) and a round-corner cutout (480mm x 380mm). Cutout size tolerance is ≤ ±0.5mm. This ensures a seamless, watertight fit between the sink and the countertop. Three Φ35mm holes are pre-drilled for standard US bathroom fixtures (faucet, soap dispenser, drain). The hole center distances are accurately aligned. Edges are smooth without burrs. This allows for easy, standard installation of all fixtures, achieving perfect integration between the countertop and the hardware.

Precise Edge and Chamfer Finishing

All bathroom countertop edges feature an R10 rounded corner finish. They undergo an 8-step fine polishing process. This completely removes sharp edges. It prevents injury from accidental bumps during use, enhancing bathroom safety. It also gives the edges a smooth, warm feel. This further strengthens the overall high-quality impression, meeting the detailed requirements of upscale hotels.

Full Process Quality Inspection

Drawing and Cutout Parameter Verification

The project CAD drawings are checked against the actual products. Key parameters are verified, including the overall countertop size (1200mm x 550mm), sink cutout dimensions and center distances, and pre-drilled hole positions. This ensures 100% of the countertops meet the standard installation requirements for hotel bathroom vanities and sinks.

Core Dimension Re-measurement

Each countertop’s length, width, and thickness are measured with a tape measure. All dimensional errors are controlled within ±1mm. This meets North American building material industry tolerance standards. It ensures zero rework during on-site installation.

Surface and Pattern Consistency Check

Each slab surface is inspected. The goal is to ensure the shimmering particles are evenly distributed. There should be no color differences, scratches, or stains. Consistency of the pattern between different production batches is also checked. This guarantees a uniform visual look for all hotel bathrooms, preventing mismatched “pattern” issues.

Special Inspection for Cutouts and Edges

For sink cutouts, a special check is done on edge smoothness. Edges must be free of burrs and chips. This ensures the sink installs with a watertight seal, preventing leaks. The precision of the R10 rounded edge polishing is also verified to meet hotel safety standards.

Pre-shipment Packaging and Protection Verification

A professional packaging solution is used. It combines waterproof/damp-proof film with reinforced wooden pallets. Protective PE foam strips are placed between countertops. This prevents bumps and scratches during transport. Each pallet has a clear label showing specifications, order number, and batch number. The packaging meets international ocean shipping standards for moisture and impact protection. It ensures the US client receives the goods with zero damage.
