Who We Are

Engineering
Better Spaces

Huahai Technology is a leading real estate engineering solutions provider specialising in integrated prefabricated bathroom systems. We replace traditional wet-trade construction with factory-manufactured, modular bathroom units — reducing project timelines from weeks to hours. Our systems serve residential developers, hotel operators, healthcare facilities, and urban renovation projects across China, Asia-Pacific, Europe, the Middle East, and beyond.

The Problem

Why Prefabricated?

The construction industry faces mounting pressure — rising labour costs, a shrinking skilled workforce, and unpredictable quality. Traditional bathroom renovation is one of the most time-consuming and waste-intensive parts of any build.

01
Labour Shortage
The average age of construction workers is rising, and only 3.7% of new-generation workers are willing to enter the trade. Skilled tilers and plumbers are increasingly scarce and expensive.
02
Long Timelines
A single traditional bathroom takes 16+ days — wall chasing, waterproofing, tiling, ceiling work, and fixture installation across multiple trades with unavoidable waiting periods.
03
Inconsistent Quality
On-site craftsmanship varies widely. Without factory-controlled production, defects in waterproofing and tiling are common and difficult to detect until damage has already occurred.
04
Waste & Disruption
Wet trades generate significant dust, noise, and construction debris — a critical issue in occupied buildings, operating hotels, and active healthcare environments.
Our Solution

The GRC Integrated
Bathroom System

Our flagship GRC (Glass Fibre Reinforced Concrete) system delivers the authentic look and feel of a traditional tiled bathroom — with none of the on-site complexity. Every component is factory-manufactured and arrives ready to assemble. Dry installation. Same-day use. 60-year service life.

GRC Integrated Bathroom System
GRC Waterproof Chassis
The foundation of every system. GRC material integrates the tile layer, waterproof membrane, and adhesive in a single moulded unit. Suitable for same-floor and cross-floor drainage structures, with full 360° waterproofing at every joint and node. Zero leaks guaranteed.
Lightweight High-Strength Wall Panels
8mm standard GRC panels weigh just 15kg per unit, with compressive strength exceeding 40MPa and flexural strength above 34MPa. Single-point hanging load capacity of 50KG with no drilling restrictions. Safe service life of 60+ years — far exceeding international standards.
Any Size, Any Style
Using 3D printing technology, our GRC system is free from mould size limitations. Fully customisable to any floor plan, layout, and tile finish. Choose from 8 wall tile patterns and 4 floor pan options — from marble-effect to stone textures.
Integrated Ceiling & Fittings
The suspended ceiling integrates lighting, ventilation, and water supply with built-in maintenance access hatches. Matched to the room tile design for a seamless, hotel-grade finish. One-time installation — no secondary work required.
Performance

Huahai vs Traditional Construction

Huahai GRC System Traditional
Installation time 4 hours 16 days
Workers required 2 10+
Structural waterproofing ✓ ✗
Construction waste None Significant
Quality consistency Factory-controlled Variable
Custom sizing Any dimension Limited
Service lifespan 60+ years 15–20 years
4-Hour Installation
2 workers, 9 standardised steps, same-day usable. Traditional construction requires 16 days across multiple trades and waiting periods.
Reliable Quality
Every unit manufactured under factory conditions. Zero dependence on on-site craftsmanship — consistent results across every project, every time.
Lower Total Cost
Shorter timelines mean lower labour costs and faster project handover. Long-term maintenance costs are also significantly reduced by design.
Process

Installed in 4 Steps

All bathroom components are pre-manufactured at our factory. 2 workers complete on-site assembly in under 4 hours — no wet trades, no curing time, no disruption.

STEP 01
Measure & Design
Submit your floor plan. Our engineering team produces a custom system layout with precise component specifications within 1–2 business days.
STEP 02
Factory Production
Your bathroom system is manufactured under controlled factory conditions — chassis, wall panels, ceiling components, and fittings — delivered within 30 days.
STEP 03
On-Site Assembly
2 workers assemble the complete bathroom using dry construction methods. No wet trades, no waiting for materials to cure. Completed in 4 hours.
STEP 04
Ready to Use
Fully functional bathroom, same day. Inspected, sealed, and handed over. No snagging, no return visits, no secondary waterproofing required.
