Underslab plumbing involves installing water supply and drainage pipes beneath a building’s concrete slab. This essential phase ensures efficient flow and waste removal for commercial kitchens, bathrooms, utility rooms, and other critical areas.

Rough-in plumbing is the stage where water supply and drain lines are installed within walls, floors, and ceilings before drywall and finishes go in. This step sets the framework for all plumbing fixtures and systems.

The plumbing trim-out phase involves installing all visible fixtures such as faucets, sinks, toilets, and other hardware after walls and floors are finished. We carefully fit and test each fixture to ensure optimal function and a professional, polished finish that meets the standards of your commercial space.
