I agree that buying quality fixtures is the way to go.  We have had our best results using Moen, plus they carry a Lifetime Warranty.  There are many good models but we have had the most success with the Kingsley line for bathroom remodeling.  Not only is Moen Kingsley available in the most popular finishes of Chrome, Brushed Nickel and Oil Rubbed Bronze but you can coordinate with matching fixtures for the entire bathroom including accessories like toilet paper holders, towel bars, robe hooks, etc.  Let's face it, you get what you pay for!

Generally speaking the roofline actually determines where the gutters are supposed to be. Whenever there is water flow coming off the home there should be gutters and it should be all around the home. So, unless your home was designed by Frank Lloyd Wright and it has the proper underground drainage built-in, you should contact your local gathering contractor.
