Measuring: Measure the shower area to ensure proper fit of the flashing
Before installing shower flashing, precise measurements of the shower area are crucial to ensure a proper fit. This involves measuring the length, width, and height of the shower space, as well as any protrusions or irregularities that may affect the placement of the flashing. Use a measuring tape or a laser measurer for accuracy, and record your measurements to refer to during the installation process.
When measuring, consider the type of flashing you will be using, as different materials may require slightly different measurements. For example, if you are using a peel-and-stick flashing, you may need to add an extra inch or two to your measurements to account for the adhesive backing. Additionally, take into account any fixtures or fittings that will be installed in the shower area, such as a showerhead or soap dish, and adjust your measurements accordingly.
