The light fixtures are glass. The bulbs are fluorescent.
The granite counter top was a remnant, just needed a bit of a trim and polishing. In addition to the 'pseudo-green' aspects of that approach, a "new" granite counter top cost 5 times as much (ouch!). The sink bowl is glass, which seems fairly green to me. The vanity is wood and bamboo, rather than composite materials which put formaldehyde/urea into the air. In its first life, it was a buffet.
You can't see it here, but all of the framing was recycled lumber, taken from this house when I demolished the original bathrooms and a closet. I cut the nails rather than pull them out (too difficult). Many of the studs fit with minimal, and sometimes no, trimming, I just had to use trial and error to see what fit. The drywall is mold-resistant paper-free, to avoid need for replacement due to mold issues that happened with the original bathroom. A ceiling fan will also draw out moisture, unlike the original bathroom.
The light is fluorescent - I tried to go with even more energy efficient LEDS but the ones that I could find were not bright enough. I'll keep trying when these burn out, which I hope won't be for a long time.
