Of every room we remodel, the primary bathroom is the one where homeowners have thought hardest about what they want and least about what it costs. The Pinterest board is full. The budget is a question mark.
So here's the straight version. A master bathroom remodel in NJ runs $35,000 to $85,000 and up in the Central NJ towns we serve. That's the primary suite tier: large walk-in shower, freestanding tub, double vanity, full tile package, and usually heated floors. Where you land in that range comes down to three decisions.
Decision one: does the layout change?
Keeping fixtures where they are keeps plumbing costs down and puts you at the lower half of the range. Moving the shower to steal space from a closet, or splitting the toilet into its own water closet, means re-running supply and waste lines through the floor. In a slab-on-grade home that means cutting concrete. Worth it when the existing layout is genuinely bad. Not worth it to move a toilet eighteen inches.
Decision two: the shower
The walk-in shower is the centerpiece of every primary bath we build, and it's the line item with the widest swing. A quality tiled shower with a frameless glass panel and a single valve is one number. A curbless entry, a bench, body sprays, a rain head plus handheld, and floor-to-ceiling large-format tile is a different number, sometimes $15,000 different. Our take: spend on the pan, the waterproofing, and the glass. Skip the body sprays. Nobody uses them after the first month, and every penetration in a tiled wall is a future maintenance point.

Decision three: heated floors and the comfort layer
Electric radiant floor heat adds roughly $1,500 to $3,500 depending on the room and it is the upgrade clients thank us for a year later. January in Mercer County makes the case better than we can. The same goes for a properly sized exhaust fan on a humidity sensor: cheap, invisible, and it protects the tile work you just paid for.
What's actually worth it
After building these across Hamilton, Princeton, and West Windsor, our honest ranking: waterproofing and tile execution first, because everything else sits on top of it. The shower second. Heated floors third. The freestanding tub last. Half our clients tell us a year later they use the tub a handful of times. If the tub is what pushes your budget past comfort, that's the item to cut, and you can always keep the plumbing rough-in so a future owner can add one.
