When designing a modern space, the first step is to get rid of (or at least hide) any unneeded clutter. Once the room is cleared, add a few multifunctional pieces. Be sure that every element you bring in has a clearly defined purpose in addition to driving home your modern aesthetic. Carefully distribute items throughout the room so that it feels balanced.
Choosing lighting is a crucial part of modern design style especially in the bathroom. There are plenty of lighting choices available to you. Modern design is all about lines and geometric shapes, so keep that in mind when shopping for light fixtures, windows, and placement of lighting. However, make sure to remember that the quality of the light is further more important than the actual light fixture. Skylights are great idea for modern bathrooms, because they add more natural light and interest to your bathroom.
