Plumbing estimate template
A plumbing estimate built around what actually drives the price: fixture counts, the water heater, valves and supply lines, and the two clauses that prevent most disputes. The example is pre-filled with sample figures — overwrite them with your rates and download a PDF.

What a plumbing estimate should include
Plumbing estimates fail for the same reason electrical ones do: a missing line, not a wrong price. Five sections cover almost every residential job.
1. Rough-in counted per fixture
Price drain and supply rough-in separately, and count them. “Drain rough-in × 4 fixtures” is checkable by the client and adjust automatically if they add a fixture mid-job. A single “rough-in” line is neither.
2. Equipment and specialty work
Water heaters, pumps, filtration, gas lines. Quote the equipment with installation as one named line, and separate the haul-away of the old unit — it is a real cost and clients accept it more readily than a higher labour number.
3. Fixtures set
Setting a toilet or a sink is a small number that clients expect to see. Hiding it inside rough-in makes the rough-in look expensive.
4. Permits
Water heater replacements and any change to drain lines usually need one. Put the fee on its own line with the jurisdiction's name.
5. Access, restoration and hidden conditions
This is the section that saves you money. State who opens the wall, who closes it, and what happens if the pipe behind it is not what the estimate assumed. A hidden-conditions clause plus a photo is the difference between a revised estimate and an argument.
How to price plumbing work
Fixed price where the scope is visible — fixtures, water heaters, repipes. Time and materials where it is not — leak diagnosis, drain clearing, anything behind a wall. Write which basis you are using on the estimate, because a client who assumed “fixed” will not accept an hourly surprise later.
Charge a diagnostic fee that is credited against the repair if they proceed. It stops unpaid call-outs without making the first visit feel like a penalty.
Example: water heater replacement with a bathroom rough-in
Sample figures for illustration only — replace them with your market rates. Tax is left at 0% because many states do not tax residential plumbing labour.
| Line | Qty | Rate | Amount |
|---|---|---|---|
| Water heater replacement (50 gal, installed) | 1 | 1,450.00 | 1,450.00 |
| Permit & inspection | 1 | 285.00 | 285.00 |
| Shut-off valves & supply lines | 6 | 95.00 | 570.00 |
| Drain rough-in (per fixture) | 4 | 220.00 | 880.00 |
| Supply rough-in (per fixture) | 4 | 185.00 | 740.00 |
| Toilet & sink set (labour) | 2 | 150.00 | 300.00 |
| Fittings, solder & consumables | 1 | 180.00 | 180.00 |
| Pressure test, clean-up & haul away | 1 | 160.00 | 160.00 |
| Subtotal | 4,565.00 | ||
| Deposit (30%) | 1,369.50 | ||
| Balance on completion | 3,195.50 | ||
Three mistakes to avoid
- No hidden-conditions clause. Old galvanised pipe, a rotten subfloor, a joist in the way — without the clause you pay for all of it.
- Forgetting restoration. “Drywall repair by others” must be written down, or the client assumes it is included.
- Absorbing the diagnostic fee. It trains clients to call you out for a free opinion and then hire someone cheaper.
FAQ
What should a plumbing estimate include?
Fixture counts for rough-in, specialty equipment such as the water heater, valves and supply lines, the permit, and the two things plumbers most often forget: an access and restoration line, and a hidden-conditions clause for what is behind the wall.
Should I quote a fixed price or hourly?
Fixed price for work you can see and scope — fixtures, water heaters, repipes. Hourly or time-and-materials for diagnosis jobs where you do not know the extent until you open the wall. Put the pricing basis on the estimate so the client knows which one they are approving.
How much deposit is normal for plumbing work?
Twenty-five to thirty-five percent is typical on residential jobs, because the water heater or fixtures are ordered before the work starts. State it on the estimate and let the balance land on the invoice.
What do I do if I find hidden damage behind the wall?
Stop, photograph it, and issue a revised estimate rather than absorbing the cost. The hidden-conditions clause in the notes is what makes this conversation easy — without it, the client believes the original number still stands.
Can I turn this estimate into an invoice?
Yes. Switch the document type at the top to Invoice when the client approves — the line items and totals stay, and you change the number and the due date. When the job is paid, switch to Receipt.
Is the template free for commercial use?
Yes. Download the PDF and send it under your own business name. No account, no watermark, and nothing you type leaves your browser.
