Basement Bathroom Addition · Roselle Park, NJ
Add a functional bathroom to your basement with interior-only work focused on code, waterproofing, and efficient layouts. We handle design, permits, and finish carpentry.
We build full basement bathrooms in Roselle Park and Union County: rough plumbing tie-ins, sealed shower pans, subflooring, ventilation, lighting, tile, fixtures, and trim. We coordinate electric and plumbing inspections and keep work inside the existing foundation unless an addition is required for living space.

FAQ
Typical costs vary with scope and site conditions; expect a broad range. We provide a free walkthrough to assess plumbing access, grade, and finishes, then deliver a written estimate with itemized line items.
Average timeline is 6–10 weeks after permits, depending on complexity and inspector availability. We schedule work in phases to minimize delays and keep you updated weekly.
Interior basement work limits dust and noise mostly to the basement. We isolate the work area, run negative air when needed, and protect common areas. We’ll review access and staging during the walkthrough.
Request a consultation and on-site walkthrough. We measure the space, check plumbing and grade, discuss finishes, then provide a written estimate and permit plan to move forward.
