Plumber Price List: How to Build Flat-Rate Pricing for Common Plumbing Jobs

A plumber price list is a set of flat rates for common jobs, such as faucet and toilet replacements, garbage disposals, water heaters, drain clearing, shutoff valves and hose bibs, built from standard task time, your billable hourly rate and parts with markup. Customers see one price before you start, and every plumber on your team quotes the same job the same way.

How to calculate each flat rate

Flat rate = standard task time × billable hourly rate + parts × markup + disposal or permit fees

Use realistic task times that include setup, the work, testing and cleanup. Your billable hourly rate should cover wages and burden, vans, tools, insurance and overhead, divided by billable hours. See how to price a plumbing job.

Common items to include

• Replace a kitchen or bathroom faucet. See faucet installation cost.
• Replace a toilet, or rebuild the tank internals. See toilet installation cost.
• Install or replace a garbage disposal. See garbage disposal installation cost.
• Replace a tank water heater (by size and fuel), or install tankless. See water heater installation cost.
• Clear a sink, tub or main drain. See drain cleaning cost.
• Replace shutoff valves, supply lines, P-traps
• Replace a hose bib
• Install a sump pump. See sump pump installation cost.

Add difficulty tiers

The same faucet swap takes far longer with corroded fittings or a cramped vanity. Offer standard and difficult versions of key tasks, or a clear add-on for seized valves and extra fittings, so you don't absorb the difference.

Diagnostic fees

For leaks and unknown problems, charge a diagnostic fee and then present flat-rate repair options. Many plumbers credit the fee toward approved work.

Present options

Repair vs replace, standard vs upgraded fixture, and optional add-ons like new shutoffs give customers choices without discounting. See how to handle customers who want a discount.

Quote from photos

A photo of the fixture, the shutoffs and the space under the sink or around the water heater tells you most of what drives time. Fast Snap Pro turns customer photos into an itemized estimate from your plumbing price book. See plumbing estimating software.

Example: building a flat rate for a toilet replacement

With a billable rate of $160 per hour:

Line item	How it's priced	Example
Standard task time (1.75 hr incl. testing)	1.75 × $160	$280
Wax ring, bolts, supply line	Cost + markup	$35
Haul-away of old toilet	Flat	$40
Toilet (if you supply it)	Cost + markup	Varies
Flat rate (labor + parts, customer-supplied toilet)		$355

Illustrative numbers only. Use your own rates, production times and local costs.

Add a "difficult" version for seized flanges or a rotted subfloor so those jobs are priced properly instead of absorbed.

Frequently asked questions

Is flat-rate plumbing pricing better than hourly?

For common jobs, flat-rate usually closes more work because customers know the price up front. Hourly still suits open-ended diagnostic work.

How much should plumbers mark up parts?

It varies by company and part cost. Many use a sliding markup, higher percentage on small parts and lower on expensive equipment.

Should a plumber's price list be shown to customers?

Show the price for the job being quoted. Publishing a full list is optional; some companies show "starting at" prices online.
