Hidden water damage behind the shower or tub
Possible$800 – $3,000
Newer waterproofing usually holds, but any past leak shows up the moment the surround comes off.

Project health summary
Overall complexity
Straightforward
The scope stays close to the existing footprint, which keeps trade sequencing simple and estimates tight.
Budget confidence
30%
Unknowns in your answers widen the range. The gap between low and high is $15,100 — resolving them before signing narrows it fast.
Biggest budget risk
Labor
Labor and Fixtures together carry 71% of the expected total. A change order in either one moves the whole project.
Timeline confidence
3–6 wks
The schedule has normal slack. Material lead times, not labor, are the usual cause of slippage here.
Permit complexity
Minimal
Cosmetic scope in most jurisdictions. Confirm locally before assuming no permit is required.

Where your money concentrates
These four categories decide whether this project lands on budget.
01Labor
$13,300 · 58%
Trade time in a small, wet, inspected room is the dominant cost in almost every bathroom.
02Fixtures
$2,800 · 12%
Fixture prices vary more than any other category for near-identical function.
03Vanity & Cabinetry
$1,400 · 6%
Cabinetry is a single visible purchase, which makes it the easiest place to over- or under-spend.
04Tile & Walls
$1,100 · 5%
Tile is priced by setting labor and waterproofing, not by the tile itself.
Where you can save without cutting quality
Quartz remnant instead of full slab
A single-vanity top rarely needs a full slab. Fabricators sell remnants at 30–50% off with the same material.
−$300
Spend tile budget where it shows
Use the premium tile in the shower niche and floor, and a clean large-format field tile everywhere else.
−$300
Handle demolition yourself
Demo is the least skilled line item. Doing it yourself (with dumpster rental) typically removes most of this cost.
−$200
Buy fixtures directly
Contractor fixture markup usually runs 10–20%. Supplying your own toilet, faucets, and lighting captures that margin — confirm warranty responsibility in the contract first.

What could increase this estimate later
Every bathroom hides something. These are the surprises most likely in a home of this age and scope — priced, so you can negotiate them before they become emergency change orders.
Realistic added exposure
$1,000
Full range $2,150 – $9,900
Subfloor replacement
Unlikely$600 – $2,200
Soft or delaminated plywood under the toilet flange is common wherever a wax ring has failed at some point.
Electrical upgrades to meet current code
Unlikely$500 – $3,500
Older bathrooms often lack GFCI protection and a dedicated circuit; an inspector will require both once the wall is open.
Permit requirements broader than expected
Unlikely$250 – $1,200 plus delay
Moving fixtures or adding circuits usually pushes a cosmetic permit into a full plumbing and electrical review with separate inspections.
Hold this as contingency outside the contract price. A contractor who refuses to price these in advance is telling you how the change orders will go.
