The fixtures you and your designer pick will add the crowning touch to your home. The best ones to buy are solid brass. They last longest and need the least maintenance. You can tell a fixture is solid brass by its weight. Die-cast zinc alloy faucets hold up well too, and are a bit less expensive. Don't buy faucets with plastic bodies -- they won't last.

Good lighting adds to your home's glamour. Avoid fluorescent light in your bathroom because its cool-spectrum light alters the look of skin tones in the mirror. But you want to make sure you have adequate lighting for applying makeup or shaving. A skylight can add natural, warm light to your bath. Some designers are even adding lights to the vanity toe kick for a nice effect.
