Natural light from the window instantly brightens up a small bathroom. Where possible, leave windows unadorned with clear or frosted glass.
Light gives the effect of open space so make the most of your windowsill. Remove all clutter and put up some light or pastel-coloured sheer curtains or blinds to ensure you are maximising the chances of getting sunshine throughout the day.
In a loft conversion consider installing skylight windows. These are perfect for bringing in as much daylight as possible without worrying about privacy issues.
For windowless bathrooms; choose a lighting fixture that will bring as much of your electrical light into the room as possible. Don’t go for heavy or domineering light shades.
If you can, add more lighting fixtures around the room like sconces on either side of the mirror, for example. If you’ve got space – hang a large mirror to reflect light around the room and give the walls a fresh lick of paint with some bright or fresh white colourings.
