Professional Bathtub Overflow Installation

Installing a bathtub overflow is crucial for preventing water damage and ensuring code compliance. The cost for a brass overflow kit ranges from $50 to $150, while PVC kits are typically $20 to $50. Labor costs can vary, averaging $200 to $500 per installation depending on complexity and location.

Importance of Accurate Overflow Installation

• Water intrusion is a leading cause of warranty callbacks.

• Incorrect gasket compression can void warranties.

• Inspectors focus on overflow height and trap arm slope.

• Plumbing details impact perceived build quality.

Common Contractor Challenges

• Difficulty finding current pricing for materials.

• Unclear labor allowances in tight spaces.

• Blueprint discrepancies causing on-site guesswork.

• Manual data entry delaying invoicing.
