Statement of Work
Ref: 2026-001 • Standard Business Template
Overview
This agreement outlines the professional relationship between the Plumber and the Client for the specified bathroom remodel, emphasizing that the Plumber is responsible only for the installation and integrity of the plumbing systems. Due to the nature of renovation, the Plumber shall not be held liable for pre-existing conditions, including but not limited to, corroded pipes, inadequate venting in adjacent rooms, or structural deficiencies found upon demolition. All work will be performed in accordance with local building codes, and any required permits obtained by the Plumber will be billed as a pass-through cost to the Client unless otherwise specified.
To protect both parties, the Client agrees to provide a clear workspace and timely access to the main water shut-off valve. The Plumber’s liability for water damage is strictly limited to issues directly resulting from the new installation and does not extend to the failure of client-provided fixtures or secondary damage caused by pre-existing plumbing. Any changes to the original layout or fixture selection after the rough-in phase has commenced will result in additional labor charges and must be documented via a formal change order to ensure project continuity and billing accuracy.
Concealed Pipe Corrosion
Opening a wall to find galvanized pipes that crumble upon touch requires an immediate change order to avoid system-wide failure during the install.
Subfloor Structural Integrity
Notching joists for a new 3 inch drain line can compromise the floor, leading to liability issues if structural reinforcement was not in the original bid.
Fixture Compatibility
Installing homeowner-supplied fixtures often leads to missing parts or non-standard thread sizes that halt production and cause unpaid downtime.

Why Bathroom Remodel Plumbers need a clear contract
Bathroom remodeling is one of the most high-risk niches for a plumber because you are working in tight spaces where water, electricity, and expensive finishes meet. Without a solid contract, you are liable for everything from a slow leak in a new PEX line to a cracked custom shower pan. Clients often assume that a quote for a simple swap includes fixing decades of corrosion in the main stack or upgrading venting to meet modern code. A written agreement defines exactly where your pipework starts and stops. It prevents the homeowner from holding your final payment hostage because they bought a non-standard vessel sink that requires a wall-mounted faucet you did not bill for. In this trade, clarity is the difference between a profitable week and a lawsuit.
Real-world scenario
You agree to a flat-rate master bath remodel for a client who says they just want to swap a tub for a walk-in shower. Once you demo the old cast iron tub, you find the subfloor is saturated with rot and the drain line is a rusted mess of drum traps and lead bends. Without a clear contract, the client expects you to rebuild the floor and replace the entire drainage branch for the original price. You spend three extra days on your knees fixing someone else's 50-year-old mistakes while your other scheduled jobs fall behind. Because you did not have a clause for Discovery of Non-Code Compliant Plumbing, the homeowner refuses to pay the extra 1,500 dollars in labor and materials. You end up making less than minimum wage on the project after accounting for the materials you had to buy out of pocket just to finish the job and get out. You also face the risk of the homeowner blaming you for the existing damage because it was not documented before you started.
🛡️ What this contract covers:
- ✓Rough-in plumbing installation including the layout of drain, waste, and vent lines along with hot and cold water supply lines for all designated fixtures.
- ✓Installation and connection of finish fixtures including the bathtub or shower valve, toilet, vanity sink, and faucet hardware.
- ✓Final pressure testing of all systems and a comprehensive leak inspection to ensure compliance with local plumbing codes and manufacturer specifications.

Frequently Asked Questions
What happens if mold or rotted subflooring is discovered after the walls are opened?
Discovery of mold, hazardous materials, or structural rot constitutes 'unforeseen conditions.' Work will pause and a written change order will be required to address these issues before plumbing installation continues.
Are the decorative fixtures like the bathtub and faucets included in the service price?
Unless explicitly stated in the estimate, the client is responsible for purchasing finish fixtures, while the plumber provides all internal rough-in materials like copper, PEX, and PVC piping.
