Serene, soothing, and just plain pretty, sea and sky hues are ideally suited to spa-like bathroom designs. But you'll note as you browse our blue bathroom ideas that blue, in all its lovely hues, provides the foundation for a diverse collection of bathroom designs. You'll see how aquamarine glass tiles and white bathroom vanities partner to establish beach-house character, and how cream walls set off slate-blue woodwork and cabinets to create country farmhouse charm. Learn how to correctly use blue bathroom tiles to produce striking wall treatments, sparkling shower alcoves, and style-appropriate floors. Try combining indigo granite countertops and bluestone floors with awning-stripe fabrics to fashion a blue bathroom with a nautical bent; or pair turquoise tiled or painted walls with vibrant citrus-hue and pale blue bathroom accessories for personality plus. Got a yen for elegance? Look to saturated blues like sapphire, royal, and cobalt to set a sophisticated stage that glitters with gilded mirrors and shiny brass fittings. Spaces done up in earth tones, crisp whites, or silvery grays benefit from touches of blue. Peruse our gallery of bathroom pictures to see how blue bathroom accessories -- including porcelain and glass knobs, countertop vessels, window treatments, and plush area rugs -- energize neutral rooms.
