What's the Most Expensive Part of a Bathroom Remodel?
2026-08-09
Short answer
Labor, not materials, is the biggest line item on most bathroom remodels — typically 40–50% of the total. Within labor, moving a plumbing line is the single most expensive change you can make, usually adding $2,000–$5,000 to a project on its own.
Where the money actually goes
Industry cost guides split a typical bathroom remodel roughly into labor at 40–50% of the total, materials at 35–50%, and permits plus miscellaneous costs making up the rest. Here's how that breaks down by trade:
| Item | Typical range |
|---|---|
| Demolition | $500 – $1,500 |
| Plumbing rough-in and fixtures | $1,000 – $4,000 |
| Electrical | $500 – $2,000 |
| Tile installation (floor + shower) | $1,000 – $3,000 |
| Carpentry and finish work | $500 – $1,500 |
| Moving a drain or supply line | adds $2,000 – $5,000 |
These are national industry ranges, not a quote — get a real, line-item DFW estimate before you budget against them.
The biggest material costs
On the materials side, tile — floor and shower surround together — and the vanity or countertop are consistently the largest line items. Both scale directly with your choices: a standard-size ceramic tile costs far less than a large-format porcelain or natural stone, and a stock vanity costs far less than a custom one.
Why moving plumbing costs so much
Relocating a drain or supply line means opening the wall or floor, running new lines to code, and closing everything back up before a single tile goes down — real demolition and rough-in labor, not a quick swap. It's the change that most reliably pushes a project from one budget tier to the next. If you're specifically pricing a tub-to-shower conversion, this is usually the deciding cost factor.
How to keep costs down without cutting corners
- Keep every fixture in its current location if the layout already works
- Choose a standard-size tile over large-format or custom stone
- Pick a stock or semi-custom vanity instead of a fully custom build
- Get a written, line-item estimate before committing so you know exactly where your money is going
