Hotel Guest Room Renovation Scenario
Testing Scenario & Pain Points: Our hotel renovation project required fast construction to minimize operational downtime, and traditional tile bathrooms had recurring water leakage issues that increased maintenance costs. We needed a solution that could meet both speed and waterproof requirements.
Actual Usage & Testing Process: We installed 50 RAUNPH prefab bathrooms in batches, using dry construction methods without cement or tile laying. We conducted 24-hour water leakage tests on each unit after installation.
Real Experience & Results: All units passed the water leakage test with zero seepage, completely solving the long-standing leakage problem. The installation speed was 80% faster than traditional methods, reducing the project’s bathroom construction period from 45 days to 9 days.
Solved Pain Points: Eliminated water leakage risks, shortened construction downtime, and reduced labor costs by 60% compared to traditional tile bathrooms.
Long-Term Operation & Maintenance Scenario
Testing Scenario & Pain Points: Hotel bathrooms are in high-humidity environments, which easily cause mold growth and require frequent cleaning. Traditional tile grout lines are hard to clean and prone to mold.
Actual Usage & Testing Process: We monitored the bathrooms’ condition for 6 months, conducting weekly cleaning and monthly mold inspections.
Real Experience & Results: The SMC surface remained mold-free, and cleaning only required wiping with clear water—no need for special mold-removing cleaners. Maintenance time per unit was reduced by 70% compared to traditional tile bathrooms.
Solved Pain Points: Reduced daily maintenance time and costs, eliminated mold growth in high-humidity environments.
