Bathroom Addition Experts in Passaic & Bergen County

Add a brand-new bathroom where you need it most. We handle plumbing, electrical, waterproofing, tile, fixtures, and all permits — from planning to final inspection.

About This Service

A bathroom addition adds an entirely new bathroom to your home where one does not currently exist. Whether you need a half bath on the main floor, a full bathroom near a guest bedroom, or a second bathroom upstairs to eliminate the morning bottleneck, this project adds real functionality and significant resale value.

Adding a bathroom is more complex than remodeling an existing one because it requires running new water supply lines, drain lines, and vent stacks to a location that was never plumbed. In many Northern NJ homes, this means routing plumbing through finished walls or floors, tapping into the existing drain-waste-vent system, and upgrading the water heater capacity if needed. We assess all of this during the initial consultation so the scope and cost are clear before any work begins.

Every bathroom addition we build includes proper waterproofing, code-compliant ventilation, GFCI-protected electrical circuits, and finishes that match the quality and style of your existing home. We handle all permit filings, plumbing and electrical inspections, and coordinate every trade under one contract.

FAQ

Bathroom Addition Experts in Passaic & Bergen County FAQs

How much does it cost to add a bathroom?

A half bath addition (toilet and sink) typically costs $15,000 to $25,000. A full bathroom with shower ranges from $25,000 to $50,000+ depending on location, plumbing complexity, and finish selections. We provide a fully itemized estimate after the in-home assessment.

Can you add a bathroom anywhere in my house?

In most cases, yes. The key factor is proximity to existing plumbing and drain lines. Locations closer to existing plumbing are less expensive. We can add bathrooms in basements (with ejector pumps), attics, closet conversions, and new additions. We assess feasibility during the consultation.

How long does a bathroom addition take?

A typical bathroom addition takes 4 to 6 weeks from rough-in to completion. Projects requiring significant structural work or long plumbing runs may take longer. We provide a detailed timeline during the estimate phase.

Do I need a permit to add a bathroom?

Yes. Adding a bathroom requires plumbing, electrical, and building permits. We handle all permit applications, schedule inspections, and ensure every aspect of the work meets NJ building code requirements.
