Bathroom remodel cost.
A bathroom remodel's price swings on scope and whether plumbing moves, not just square footage.
Bathroom remodel cost by project scope
| Cosmetic refresh (fixtures, paint, vanity) | $3,000 – $8,000 |
| Mid-range full remodel | $8,000 – $18,000 |
| High-end / luxury remodel | $20,000 – $45,000 |

Bathroom remodel cost by type
One decision splits the whole budget: does anything move?
Bathroom remodels price by tier and square foot, but the tier is set by a single question. A cosmetic refresh that swaps fixtures in place runs about $80–$120 per square foot. A mid-range remodel runs $120–$280. The jump between them is almost entirely whether the toilet, tub, or shower drain changes position, because that means opening the floor and rerouting drain lines and vent stacks.
What actually moves the price
Moving the toilet, even a few feet
This is the single most reliable budget blowout in the trade. Relocating a toilet means new drain routing and often a new vent stack, work that is invisible in the finished room and expensive in the floor. Keeping fixtures in their existing positions is the highest-impact cost control available.
What the walls are hiding
Older homes routinely reveal galvanized or cast-iron supply and waste lines that have to be replaced once exposed, adding roughly $500–$2,000. This is not a contractor upsell; it is code and common sense once the wall is open.
Pipe material for the runs you do replace
PEX runs about $1.50–$4.00 per linear foot installed. Copper runs $4–$12. Copper lasts longer and costs more; on a small bathroom the difference is modest, on a whole-house repipe it is not.
Access, which is a labor multiplier not a line item
Open walls and exposed joists mean fast work. Tile walls and finished ceilings that must be cut and patched add roughly 20–40% to labor hours. The same scope in a second-floor bathroom over a finished room costs materially more than in a basement with open framing.
What a complete quote names out loud
- Whether the layout changes, stated plainly, and what plumbing that entails
- Who pulls the permit for drain and vent work (rough-in plumbing requires a licensed plumber virtually everywhere)
- An allowance for replacing old supply or waste lines found once walls are open
- Waterproofing method behind tile, which is where cheap bathroom jobs fail first
- Fixture allowances stated as dollar figures, not as 'builder grade'
- Who patches and repaints ceilings below if the floor has to be opened
The one to watch: A quote that prices a layout change at the same rate as a fixture swap. If the drain moves and the bid does not name the drain work, the change order is already written.
Bathroom remodel cost: FAQ
How much does a bathroom remodel cost?
Most bathroom remodels land between $10,000 and $30,000, with a national average near $16,500. Mid-range projects run roughly $120–$280 per square foot. Size, whether the layout changes, and fixture quality move the number more than anything else.
Why does moving the toilet cost so much?
Because it is drain work, not fixture work. Relocating a toilet means opening the floor, rerouting the drain line at the correct slope, and often extending or adding a vent stack. None of it is visible in the finished room, which is why it surprises people.
What does a $20,000 bathroom get you versus a $50,000 one?
At $20,000 you are typically getting a full mid-range remodel in the existing footprint: new tile, vanity, fixtures, lighting, and a properly waterproofed shower. At $50,000 you are usually paying for a layout change, a larger footprint, custom tile work, higher-end fixtures, and finish carpentry.
Do I need a permit for a bathroom remodel?
For cosmetic work, often not. For anything touching drain lines, vent stacks, or electrical circuits, generally yes. Rough-in plumbing requires a licensed plumber in nearly every jurisdiction, and unpermitted work tends to surface at resale.
