What does it cost to move a toilet?
Rerouting the toilet drain about 6 to 7 feet costs roughly $1,080 to $2,250 as a US national planning range, plus $400 to $1,040 if the water supply moves too. The drain is the expensive part: opening and restoring the floor, not the pipe itself. Labor varies a lot by state and metro, and a concrete slab adds cost.
The ranges per distance
- Up to about 20 in from the existing drain: usually free inside a normal renovation.
- About 3 ft: $890 to $1,830.
- About 6 to 7 ft: $1,080 to $2,250.
- About 10 ft: $1,270 to $2,680, and beyond 10 ft the slope itself becomes the problem.
- Water supply moving too: add $400 to $1,040.
These are national planning ranges (validated August 2026), including opening and restoring the floor. Coastal metros run 30 to 50 percent higher; a concrete slab floor pushes toward and past the top of each range.
The 10-foot rule
A drain needs fall, roughly 1/4 inch per foot. Up to about 10 ft from the stack that usually fits inside the floor. Beyond that you need a raised floor, a furred-out ceiling below, or a macerator pump. More in the guide how far can a toilet be from the stack.
Calculate it for your own bathroom
Draw your bathroom in the free bathroom planner, place the existing drain, and drag the toilet where you want it. The planner shows the cost range for your distance live, warns about the slope line, and checks the code clearances while you drag.
Frequently asked questions
Why is moving a toilet so expensive?
A toilet drain is a wide pipe that must run at a steady slope (about 1/4 inch per foot) under or through the floor. Opening and properly restoring the floor along the new route is most of the bill; the PVC itself is a footnote.
Is it cheaper to keep the toilet near the old spot?
Yes, by far. Within about 20 inches of the existing drain a move usually disappears into a normal renovation. Every extra foot adds labor and floor work; a short move can stay near $890, a long one runs toward $2,680 and beyond on a slab.
How do I know the exact cost for my bathroom?
You cannot from a national table, and anyone who claims otherwise is guessing. Draw your bathroom in the free planner, drag the toilet to where you want it, and it calculates the range for your actual distance. Then get local quotes.
