A New Bathroom Addition in Gardena, Built From the Foundation Up

Nikolic Construction recently completed a bathroom addition in Gardena for a homeowner who needed more bathroom space without disturbing the existing floor plan inside the house. Rather than remodeling an existing bathroom, the homeowner chose to add brand new square footage to the side of the home.

This bathroom addition in Gardena required a new concrete foundation and footing, full wood framing tied into the existing roofline, plumbing rough in for a toilet, sink and shower, new electrical circuits, a new window, and an exterior stucco tie in that blends the addition into the rest of the house.

Under the direction of Daniel Nikolic, the team coordinated every trade so the structure, plumbing and electrical work all came together correctly the first time, with the addition built to pass every city of Gardena inspection.

Planning a Bathroom Addition in Gardena

What This Gardena Project Required

A bathroom addition in Gardena is not just about walls and fixtures. It means coordinating multiple trades so framing, plumbing and electrical work all come together correctly. During our evaluation and planning phase, we identified the key project requirements.

🪵 Structural & Framing Needs

New concrete footing and foundation pad for the addition
Stud wall framing tied into the existing roofline
Window installation for natural light and ventilation
Exterior sheathing and stucco tie in to match the home

🔧 Plumbing Needs

New drain, waste and vent line rough in
New water supply line rough in for sink, toilet and shower
Proper slope and support for floor drain lines
Coordination with the new foundation for pipe penetrations

⚡ Electrical Needs

New circuits for lighting and an exhaust fan
GFCI protected outlets sized to current code
Wire routing back to the main panel
Inspection ready wiring for the city of Gardena

Addressing all three trades together, rather than one at a time, helps avoid rework, keeps the project on schedule, and ensures everything is ready for final inspection. This is how Nikolic Construction approaches every bathroom addition in Gardena and throughout Southern California.

Foundation & Framing

Foundation and Framing for the Bathroom Addition in Gardena

Every bathroom addition in Gardena starts below the surface. Our crew dug and poured a new concrete footing and foundation pad sized to support the new structure, then framed the walls and roof to tie directly into the existing roofline of the home.

Foundation and Footing: A new concrete footing and foundation pad poured with anchor bolts set to meet current Gardena building department requirements

Wood Framing: Walls and roof structure framed using standard dimensional lumber, tied directly into the existing roofline so the addition looks like it has always been part of the hous

Windows, Stucco Tie In and Weatherproofing: A new vinyl window installed for light and ventilation, with the exterior stucco tied into the existing wall finish so the addition blends seamlessly with the rest of the home

This bathroom addition in Gardena was built as an attached structure off the side of the home, giving the homeowner a brand new bathroom without disturbing the existing floor plan inside the house.

Rough Plumbing

Rough Plumbing for the Bathroom Addition in Gardena

Before any drywall goes up, the rough plumbing has to be inspected and approved. Supply lines and drain, waste and vent piping were run through the new framed walls and floor, setting up the toilet, sink and shower locations for this bathroom addition in Gardena.

Drain, Waste and Vent Piping: Schedule 40 PVC piping run for the new toilet, sink and shower, matching standard practice for a bathroom addition in Gardena

Water Supply Lines: Hot and cold supply lines run through the framed walls and floor to every fixture location

Inspection Before Drywall: All rough plumbing left open for city inspection before the walls are closed up

Skipping permits or rough in inspections on a bathroom addition can create major problems when it comes time to sell the home, so we never cut that corner.

Rough Electrical

Lighting Circuits: New lighting circuits run to the addition for the vanity and overhead fixtures

Exhaust Fan Wiring: A dedicated circuit run for the bathroom exhaust fan to keep moisture under control

GFCI Protected Outlets: Outlets placed and protected to meet current code for wet location bathroom circuits
