Sinks

• It is likely that your master bathroom is being shared by you and your significant other. In order to accommodate both of your needs and to avoid stumbling over one another, have two sinks installed in the bathroom. These sinks can be on separate vanities or on a shared vanity. Choose a sink that creates a modern look for the space. Vessel sinks are a great option for a contemporary look. To get a truly modern feeling, opt for vessel sinks made of glass, stone or pottery. Add to the modern look by having a wall-mounted or waterfall faucet installed instead.
  
  

Built-In Cabinetry

• Have built-in cabinetry installed. Pick a vanity and wall cabinets that are made of dark wood and feature clean lines. To achieve a modern look, avoid handles on doors, or if you prefer having handles, use handles that are straight, sleek and silver. Consider having a few cabinets that feature frosted glass to add interest to the cabinetry.
  
  

Shower

• If you have the space for it, consider having a walk-in shower installed. These showers don't have a frame or a door, allowing you to walk right into it. If you are going with a walk-in shower, have two shower heads installed to accommodate both you and your partner.
  
  If a walk-in shower isn't an option, have a curved wall of glass blocks installed to act as the shower's protective barrier. Another option is a spa shower, complete with a rainfall shower head and jets along the walls of the unit to provide you with the ultimate shower experience.
  
  

Audio-Visual Equipment

• To turn your master bathroom into an ultimate modern retreat, incorporate audio-visual equipment into the space. Have speakers installed in the ceiling that hook up to an iPod dock so you can play your favorite tunes while getting ready for or unwinding from your day. A flat-panel television suspended on a wall will allow you to catch up on your favorite shows while you're relaxing or catch up on the news while you're preparing for the day.
