Overview of Bathroom Addition and Conversion Services

Bathroom addition and conversion services in Berea, London, Richmond, & Lexington, KY provided by JB Plumbing focus on installing complete plumbing systems for newly created bathrooms or modifying existing spaces into functional bathroom layouts. These projects require the installation or reconfiguration of water supply lines, drainage systems, venting networks, and fixture connections.


Bathroom additions involve creating entirely new bathroom spaces within residential or commercial properties. Conversions involve transforming existing rooms, such as closets, storage areas, or part of larger rooms, into fully functional bathrooms. Both require careful plumbing planning to ensure proper water distribution, drainage flow, and system integration with existing infrastructure.

Plumbing Planning for Bathroom Additions

Bathroom additions begin with detailed planning of how plumbing systems will be extended or installed to support the new space.

  • Water Supply Extension Design

    Water supply lines must be extended from existing plumbing systems or newly installed to reach the added bathroom. This includes routing hot and cold water lines to support sinks, toilets, showers, or bathtubs.

  • Drainage System Planning

    Drainage systems are designed to ensure wastewater from the new bathroom flows efficiently into the main sewer or septic system. Proper pipe slope and connection points are essential for reliable performance.

  • Vent System Integration

    Vent systems are integrated to maintain proper air pressure within the new bathroom plumbing layout. This helps prevent slow drainage and supports smooth wastewater flow.

Installing plumbing for a new bathroom involves setting up all essential water, drain, and vent connections before fixtures are installed.

  • Rough-In Plumbing for New Bathrooms

    Rough-in plumbing includes installing pipes within walls, floors, and ceilings before finishing work is completed. This stage establishes the foundation for all bathroom plumbing connections.

  • Fixture Connection Preparation

    Plumbing connections are prepared for fixtures such as toilets, sinks, showers, and bathtubs. These connections are positioned according to the bathroom layout to ensure proper alignment during final installation.

  • Water and Drain Line Placement

    Water supply and drain lines are carefully placed to ensure efficient operation and compatibility with the overall plumbing system of the property.

Bathroom Conversion Plumbing Work

  • Flange and Seal Installation

    Toilet installation includes secure connection to the waste line using a flange system that ensures a tight seal and prevents leaks or odors.

  • Venting for Toilet Systems
