The Irvine ISD RV slow retract shower door comes with hardware options in black or platinum, while the rolling door itself is white. If you encounter uneven width after installation, applying caulk on both sides of the hardware is recommended to improve appearance and prevent water leakage. For accurate sizing, measurements should be taken from the lip of the tub or shower pan where the door will close. Make sure to measure the shower opening width at multiple points (top, middle, bottom) and use the smallest measurement to ensure a proper fit. Use a metal tape measure for best precision. This approach will help ensure a secure and waterproof installation.
