Using your Brizo 36 - inch reversible linear shower drain is easy. First, install the rough part (which you need to order separately). Then, you can choose to install either the tile insert frame or the solid finished - matched grate according to your preference. Make sure to adjust the tile adjustable frame to match the thickness of your tiles, which can be between 7 and 18mm. If you're installing it against a wall, you can buy the optional wall trim separately. When it comes to maintenance, simply use a mild cleaner to clean the stainless - steel grate and frame regularly. Avoid using harsh chemicals as they may damage the finish. Also, check the drain end caps and spacers from time to time to ensure they're in good condition. And don't forget, this drain is c - UPC certified, so you can trust its quality and performance.
