We actually didn't do too much. We love it.
We replaced the floor tiles with some large format white tiles and did some waterproofing work first, including resealing the terrazzo in the shower. Then we replaced all the tapwear, and installed a new vanity and mirror. We also replaced the fan and lighting, including a pendant light over the bath.
Ah, the memories. I remember sharing the exact same colour bath, & terrattzo floored bathroom as a kid, but our bathroom had primrose tiles, with the black accent strip. We had a pedastal basin, & a shower curtain, so yours having a glass shower door, & a vanity cabinet, puts it in the $multiK/night, invitation only league. ; )
Nice job, but someone pinched your electric toothbrush.
