Can I add a bathroom without breaking through walls in Hackensack NJ?
If you're converting existing space (large closet, unused room corner) and plumbing lines are accessible, you may minimize wall opening. However, new bathrooms need supply lines, drain lines, and venting — which almost always requires some wall or floor access. A licensed plumber in Hackensack NJ can advise on the least invasive approach.
