Line-item breakdown
Use these ranges to sanity-check contractor bids.
- Demo and disposal: 5–10%
- Plumbing and rough-in: 15–25%
- Tile and shower: 20–30%
- Vanity, top, and fixtures: 15–25%
Where costs spike
Curbless showers, radiant heat, and moving the toilet or drain add labor and materials.
- Linear drains and curbless entries
- Heated floors with thermostat
- Custom glass enclosures
Wet-area labor is the silent majority
Homeowners see the vanity photo and miss the pan, membrane, tile labor, and glass. In a mid-range hall bath those wet lines often rival everything else combined. A breakdown that lumps “tile” without waterproofing is not a breakdown.
- Ask for shower, floor tile, and walls as separate rows if the room is a gut
- Glass is often a different company with a different schedule
- The fan, GFCI, and lighting are electrical — they do not hide inside the vanity line
How to use this page next to the budget-method guide
This page is the typical mix of dollars. The bathroom budget page is how you freeze those dollars. Do not paste national percentages into a bid and call it done; replace each percentage with a contractor line as soon as you have one.
- Percentages shift if you keep the tub and only refinish
- Moving a toilet blows the mechanicals percentage
- Use the calculator for a first pass, then throw the pass out when bids arrive
