Using the Brizo 48-inch linear shower drain wall trim is easy. First, check if your shower drain needs an extension. If so, use the special mounting kit included to attach the wall trim to the drain. For wall-mounted installation, simply choose the optional wall trim. When it comes to maintenance, regularly wipe the stainless - steel trim with a soft, damp cloth to keep it clean. Avoid using abrasive cleaners as they may scratch the surface. Also, make sure to check the mounting kit periodically to ensure it's secure. This will help keep your shower drain wall trim in good condition for a long time.
