Free plumbing estimate template built the way plumbers bid

By Autumn Harris, Staxen. Updated 2026-09-08.

Here is a free plumbing estimate template split the way the job actually runs: water supply, drain-waste-vent, fixtures, equipment, and labor by phase. Pipe is priced by the linear foot, fixtures and valves by the each, and the fixture allowance question is handled in writing. You can download a PDF version of the template on this page.

Water supply

Drain, waste, and vent

Fixtures and trim

Equipment

Labor by phase

Example scope

Repipe a 1,900 sf single-story house with 3 baths: replace all supply lines with PEX on a central manifold, new angle stops and braided supplies at every fixture, new hose bibbs front and rear, and a 40 gallon gas water heater with expansion tank and pan. Two days, drywall access cuts included, patching and paint excluded.

What a plumbing estimate must include

Scope split by phase

Rough-in, top-out, and trim are three site visits with an inspection between each on new work. Write the scope in those phases so the client understands why the toilet shows up months after the pipe did, and so your payment schedule can follow the same three beats.

Pipe by the foot with the material named

Half-inch PEX runs about $0.43 per linear foot in material while half-inch copper runs about $3.40, an 8x spread on the same run. An estimate that just says water piping invites the client to price-shop it against a bid using the other material. Name it.

Fixture allowances in dollars

If the client has not picked fixtures, carry a written allowance per fixture: toilet, lav faucet, kitchen faucet, shower trim. State that the allowance is the installed material budget and anything above it is a signed change order. This is the single most argued line in plumbing, so put a number on it.

Water heater code adders

Swapping a water heater is rarely just the heater. Closed systems need an expansion tank, about $48 in material, and many jurisdictions want a drain pan, seismic strapping, or a flue correction. List these as their own lines so your bid does not look $300 high against a hack's.

Exclusions for what you cannot see

Exclude repair of concealed galvanized or failing cast iron discovered during work, slab penetration surprises, wall and floor patching, and tile work around a valve cut. Cast iron replacement runs about $17.50 per foot in material alone, so a discovered stack cannot ride inside a fixed bid.

Expiration and change order terms

Give the price 30 days. State that fixture upgrades, relocations after rough-in, and concealed-condition repairs are priced and signed before work continues. Moving a shower valve three inches after the wall is closed is a change order, not a favor.

Estimating mistakes that cost plumbers money

One lump sum with no fixture allowance

The client picks a $485 farmhouse sink against your $248 budget and expects the price to hold. A written allowance per fixture turns that conversation into arithmetic instead of an argument.

Billing everything at the end

Plumbing front-loads cost: pipe, valves, and the water heater all leave your account before trim day. Tie payments to rough-in, top-out, and trim so you are not banking the job for sixty days.

Quoting PEX and getting shopped against copper, or the reverse

At $0.43 versus $3.40 per foot of material, two bids on different pipe are not the same job. Name the material and say why, and if the spec demands copper, show the client the delta rather than absorbing it.

Ignoring the water heater's supporting cast

Expansion tank, pan, straps, gas flex, flue correction. Skip them at bid time and you either eat them or make an awkward pour-day phone call. List them and let the code carry the explanation.

Touching a slab at a fixed price

Nobody knows what is under the concrete until it is open. Bid slab penetrations and under-slab drain work with a discovered-condition clause, priced per foot, or walk into the job carrying all the risk yourself.

Frequently asked questions

What goes in a plumbing estimate?

Scope split by rough-in, top-out, and trim, pipe by the linear foot with the material named, fixtures by the each or by written allowance, equipment with its code adders, labor, exclusions for concealed conditions, and an expiration date. The phases matter because inspections and payments both hang off them.

What is a fixture allowance?

A dollar budget written into the estimate for a fixture the client has not chosen yet, for example $250 installed material for a toilet. If they pick a $545 wall-hung unit, the difference becomes a change order. It lets you bid now without gambling on their taste.

Should I bid PEX or copper?

Bid what the job and local code call for, and name it on the estimate. Material alone is about $0.43 per foot for half-inch PEX against $3.40 for half-inch copper, and labor is faster on PEX too. An unnamed water piping line is an invitation to be undercut by the cheaper material.

How do plumbers usually structure payments?

A deposit at signing, a draw at rough-in inspection, a draw at top-out, and the balance at trim. On a straight water heater or fixture swap, payment on completion the same day is normal. Whatever the split, it belongs on the estimate the client signs.
