LIGHTWEIGHT (FIBREGLASS AND ACRYLIC) BATHTUB OR SHOWER BASE FLEXES AND CREAKS
Lightweight bathtubs and showers may flex and creak when installed in accordance with Manufacturer’s specifications.
One-Year - Work and Materials
Bathtubs or showers not meeting the acceptable condition shall be repaired.
Fibreglass and acrylic bathtubs and shower enclosures are lightweight yet strong. Flexing or creaking sounds can often be heard especially in large soaker-type tubs as they are filled and emptied. These fixtures are designed to withstand this type of flexing; it does not generally represent a manufacturing or installation defect.
