Bathroom Remodel Cost Calculator
The plumbing question is the one that matters most. Keeping fixtures where they are can cut a bathroom project by a third, and in a slab-on-grade house the difference is larger still.
No town pages are live yet in this state.
The single largest cost variable in any bathroom. In a slab-on-grade house it means cutting concrete.
5 by 8 is the dominant footprint in this housing stock.
Cast iron waste is standard in anything built here before about 1960. Choose unknown if you are not sure.
Estimated tub to shower conversion
$8,400to$11,200
Working days on site
5 to 9 days
Working days, so a 20 day project is roughly a month on the calendar. If this is your only bathroom, ask for the toilet to be back in service overnight.
- Tub to shower conversion, standard 5x8, 40 to 60 sq ft
- $9,500
Ranges are estimates for this market based on typical scope. They are not quotes. Actual pricing depends on the house, access, and what turns up once work starts.

How this is calculated
The project type sets a base figure, which is then scaled by bathroom size and finish level. Additions follow for plumbing relocation, waste and supply pipe replacement, and second floor access. Then the geographic adjustments apply, state first and region second, and the housing stock modifiers last.
The timeline is drawn from typical scope rather than calculated, and it is given in working days. A 20 working day project is roughly a month on the calendar. Timeline is frequently the deciding factor in a one bathroom house and almost nobody in this market publishes it.
What this tool cannot know
Every one of these matters to the final number and none of them can be read off a form. They are the reason the output is a range and the reason a contractor still has to look at the house.
- What the floor framing under the bathroom looks like, which determines whether a curbless shower is possible
- Whether there is a slow leak that has already compromised the subfloor, which is common and is repaired before anything else
- Whether the house is on a slab or over a basement, which changes the cost of moving a fixture by thousands
- What is inside the wall, which in pre-1960 housing here is frequently cast iron and sometimes galvanised
Common questions
Because it is the most requested bathroom project in this region, and because the 5 by 8 footprint it usually happens in is the dominant bathroom size in postwar capes, ranches, and three-decker units across all three states.
Cast iron drain pipe is standard in housing built here before roughly 1960. It does not need replacing because it is old. Where a remodel requires cutting into it and transitioning to PVC, that adds a known amount. Galvanised supply pipe is the more urgent find, because it corrodes closed from the inside.
Usually not, because interior work generally falls outside commission review. A new vent stack penetration through the roof can be a different matter. The toggle is here because some districts do review anything that changes the exterior envelope.
No. It is an estimate for this market based on typical scope. A contractor has to see the room, and what is behind the wall in an older house is not knowable from a form.
