Using this Brizo shower drain wall trim is easy. First, unpack the trim and the special mounting kit. Make sure the area where you'll install it is clean and dry. Use the mounting kit to attach the trim to the linear shower drain. If you want to install it against the wall, just follow the same process. As for maintenance, wipe it with a soft cloth regularly to keep it looking new. Avoid using abrasive cleaners as they can damage the stainless - steel finish. Also, check the mounting periodically to ensure it remains secure.
