Flank the mirror with fixtures placed at eye level (around 66 inches), ideally spaced 36 to 40 inches apart. Try to see fixtures in action before you buy to make sure the amount and quality of light is sufficient. If there's no room for side sconces, install a long fixture on the wall above the mirror. Don't rely on a recessed ceiling fixture (think Dracula face).
The special-order fixtures, fittings, shower pan, tile and glass block panel can take weeks to get in hand, so do the necessary legwork and ordering well in advance. Before gutting the bathroom, check to make sure that there are shutoffs for all the fixtures or a master shutoff for the entire bathroom. If not, buy ball valve shutoffs sized to fit your pipes. Then turn off the main water supply line where it comes into the house from outside, cut the pipes feeding the bathroom and install the new shutoffs right away (see Photo 7).
