Ambient lighting: This sort of lighting covers the general bathroom space. You could have a centrally fitted light - a chandelier, for example, if you want to opt for a special and creative effect - or several bright lights fitted all along the walls. If you are planning on installing recessed lights, be sure you install several recessed light fixtures or use recessed lights in combination with other styles of lights. Just a few recessed lights will not do the trick. Be sure you use glass lens over the recessed lights; plastic turns yellow with time.
By using light fixtures with dimmer control, you will alter the intensity of the light to get exactly the required relaxing feel. Dimmers are also energy-savers and your lights will last longer. Just keep in mind that you would need incandescent dimmers for incandescent and halogen lights and agreeable dimmers for any other kinds of lights.
The mirrors in the bathroom should reflect as much natural light as possible, also, artificial ones, if placed in front of windows, will reflect the light giving the impression of a wider space. The bathroom light must be clear, with controlled intensity and not bright. What ever lighting you choose, it must work with the furnishings, mirror and other decorative pieces placed in the bathroom. A classic style bathroom must have mirrors with elegant frames and shaded lighting bodies . For modern design choose mirrors without frames, spots placed strategically so that the light is not too bright.
Accent lighting: Accent lighting, as the name suggests, draws attention to a certain area or feature of the bathroom. You can use it to good effect to highlight things like an ornate mirror or an artwork or a decorative wash-basin or beautiful tiling.
