Basement Bathroom Addition · Belle Mead, NJ
Add a functioning full or half bath to an underused basement. We handle layout, waterproofing, fixtures, and code-compliant plumbing rough-ins.
We build basement bathrooms in Belle Mead and Somerset County for homeowners who need an extra bath, guest suite, or rental-ready lower level. Work includes drainage planning, sump and waterproofing tie-ins, installing vanity, shower or tub, toilet, ventilation, lighting, and tile or vinyl flooring. We coordinate plumbing hookups and electrical to meet NJ code and local inspections.

FAQ
Costs vary by size, layout, and fixtures. A basic half bath starts lower; a full bath or wet-area with tub/shower and waterproofing costs more. We provide a site-specific estimate after a walkthrough to verify drainage and access.
From signed contract to final inspection expect about 3–6 weeks for most projects, depending on permit lead times and scope. Rough-in and finishes are usually split into two main phases to allow inspections.
Expect noise and dust during demolition and rough-in. We contain dust, protect floors and furniture, and stage work to keep the rest of the house usable. We coordinate schedules to minimize consecutive noisy days.
Yes. We prepare permit-ready plans, submit to the township, and coordinate inspections with Somerset County officials as part of the project scope.
Request a consultation and walkthrough: we inspect the basement, check drainage and egress, review fixture options, and provide a written estimate with schedule. Contact us to book the on-site visit.
