A bathroom is the fastest high-value remodel in Madison. It is a small room, but it holds plumbing, electrical, waterproofing and tile in about 40 square feet, so the order of work matters. If you want it done before the holidays, the decisions below need to happen in the next two weeks.
What a Madison bathroom remodel costs
Typical North Jersey ranges for a full bathroom: a cosmetic refresh (new vanity, toilet, fixtures, paint, floor tile) runs roughly $8,000–$15,000. A full gut with a new tub or shower, tile, vanity, lighting and fan runs $20,000–$35,000. Primary baths with a walk-in shower, heated floors and custom vanities start around $35,000 and go past $60,000. Moving the tub, toilet or shower drain is where budgets jump, because it means opening the floor.
What older Madison houses hide
Many homes in town date from the early and mid 1900s. Once the walls are open, we commonly find cast-iron drains that are cracked or heavily scaled, galvanized supply lines that restrict flow, outdated wiring, and rotted subfloor around the tub. Set aside 10–15% of the budget for surprises. It is cheaper to replace a bad drain while the floor is open than to open it again in two years.
Permits and inspections
Plumbing and electrical changes require permits through the Borough of Madison construction office, and rough-in work must be inspected before walls are closed. Like-for-like fixture swaps are treated differently from layout changes, so confirm the scope with the borough before ordering anything. Licensed & insured contractors handle the permit paperwork and schedule the inspections for you.
Waterproofing is the part you never see
Most failed bathrooms fail behind the tile. A properly built shower has a sloped pan, a continuous waterproofing membrane or sheet system, and a flood test before tile goes on. Skipping this is how a $5,000 saving becomes a $15,000 mold and subfloor repair. Ask any contractor exactly how the shower is waterproofed and who tests it.
Timeline and lead times
A full bathroom typically takes 4–6 weeks on site: demo and rough-in in week one, inspections and backer board next, then waterproofing, tile, and finish carpentry. The real delay is materials. Vanities, glass shower doors and special-order tile can take 4–8 weeks to arrive, and glass is measured only after the tile is set. Order early and expect the glass to finish the job last.
Decisions to make first
- Keep the layout or move fixtures (the biggest cost driver)
- Tub, walk-in shower, or both
- Tile selection and any special-order items
- Whether to fix hidden plumbing or wiring while the walls are open
