Retrofit vs New Construction: Installing Recessed Urinal Flush Systems in Commercial Buildings

Recessed urinal flush systems offer improved durability, hygiene, and modern aesthetics compared to exposed flushometers. However, installation requirements differ significantly between retrofit applications and new construction projects. Proper planning ensures long-term performance and reduced service interruptions.


New Construction Installation Strategy

In new construction projects, recessed flush systems can be integrated during wall framing and plumbing rough-in stages.

  • Wall cavity coordination with plumbing design
  • Power routing (AC or hybrid systems)
  • Structural support for carrier systems
  • Flush volume calibration during commissioning

Retrofit Installation Considerations

Retrofitting from exposed flushometers to recessed systems requires wall modification and structural assessment.

  • Existing plumbing line compatibility
  • Wall opening and reinforcement
  • Electrical routing (if upgrading to hardwired)
  • Temporary restroom shutdown planning
