Do plan your lighting design carefully to ensure it meets your needs, and dont leave decisions until the last minute. There is often a tendency to overlook lighting but it is essential to plan ahead as wiring will have to be positioned before any such wall tiles and floor fixtures and fixed in place.
Take into account the natural light in the room when planning the design. Is your bathroom flooded with light in the morning? Can you position basins and mirrors near the window to make the most of this? What other types of lighting (artificial) will be needed to act as supplement after the sun goes down, or during winter months when light is scarce? Also consider how many panels and controls you will need and where they should logically be positioned to maximize efficiency and ease of use for guests.
For the best results, ensure that your light source does not work from one switch if possible. If a complete lighting makeover is impossible, consider a minor chance for a dramatic effect - a skylight is one idea. You can also replace a single bulb with a small track of 3 or 4 low voltage spotlights.
