I wouldn't be able to match things without actually seeing them in person, but if you want to try matching on the sites of the big box stores, I know they have the ability to narrow search selections by color, etc.
You need to visit the company web site for this and print out what you like from each one. Other then that, you need to go to the showroom.
Several of the large manufacturers (i.e.: Kohler, Delta, etc..) have numerous "collections" that include a number of different bathroom products all based on the same design theme. Delta, for example, has a "Victorian Collection" that includes everything from faucets to towel bars to lighting fixtures. You can look for these collections on the company website as Bob (Woodbridge) suggested, or you can go to a website like www.faucet.com and search for the same thing.Go to the website; run your cursor over bathroom (on the left under "Shop Departments" and then click on bathroom lighting. Scroll down until you see a light fixture made by a name you recognize; if that light fixture is part of a collection, you will see a bullet in green. Click on the bullet. Keep in mind that faucet.com is not a manufacturer and therefore list what they sell, not everything that may be available. Good luck... Tim
Check out www.signaturehardware.com. they have s large selection in faucet. Very nice! This will help you decide what color you want to with, such as nickel, chrome, copper, etc.......and then the style. Pick something you like, and just stay with the same color.
