Plumbing Estimate Template (Fixtures, Rough-In & Labor)
Plumbing estimates are built around fixtures and connections, not square footage. Price each fixture’s rough-in (supply + drain/vent) and finish (set the fixture) labor hours, add materials and fittings, then permits and your markup. A 3-fixture bathroom rough-in commonly runs around $3,200. Below is the structure and an editable template.
Plumbing prices by the connection. A bathroom isn’t “X square feet of plumbing” — it’s a toilet, a lav, and a tub/shower, each with rough-in and finish labor plus a pile of fittings. Estimate it fixture by fixture and the number holds.
The lines a plumbing estimate needs
- Fixture count — toilets, sinks, tubs/showers, water heaters, hose bibs, etc.
- Rough-in labor per fixture — running supply, drain, and vent. The bulk of the hours.
- Finish/set labor per fixture — installing and connecting the fixture.
- Materials & fittings — pipe, fittings, valves, hangers, solder/cement — easy to under-count, so build in a fittings allowance.
- Fixtures — supplied by you (marked up) or by the client (allowance).
- Permits & inspection — most plumbing work is permitted.
- Markup → margin on the whole job.
A real example: 3-fixture bathroom rough-in
| Line | Detail | Amount |
|---|---|---|
| Rough-in labor | toilet + lav + tub/shower, supply/drain/vent | $1,900 |
| Materials & fittings | pipe, fittings, valves (+allowance) | $650 |
| Permit + inspection | $300 | |
| Direct cost | $2,850 | |
| Price @ ~11% margin | ÷ 0.89 | $3,200 |
(Finish/set labor and the fixtures themselves are usually a second phase/line once the client’s fixtures arrive.)

Frequently asked questions
How do plumbers estimate jobs?
By fixture and connection — rough-in and finish labor per fixture, plus materials/fittings, permits, and markup — not by square footage.
What’s the difference between rough-in and finish?
Rough-in is running supply, drain, and vent before walls close; finish is setting and connecting the fixtures. They’re often separate phases and lines.
Why include a fittings allowance?
Fittings, valves, and small materials add up and are easy to under-count; an allowance keeps the estimate from going short.
Should the client supply fixtures?
Either way works — supply them at a markup, or use a fixture allowance and bill upgrades at cost so a fancy faucet doesn’t eat your margin.
