debrak2008, I have to figure out how to post a pic here first :P. But the countertop is those yellowish cultured marble top (you see a lot of those in the older houses) but it's not one-piece. The sink is an undermount sink, so it's just like the typical granite top with undermount sink you see now. BUT mine is not granite top obviously, and the sink is rusty and scratched. sjhockeyfan and weedyacres, Thanks for your link! Yes I looked on craigslist and saw some ads for prefab granite tops too. And my friend told me about this too. But my problem is I can't find my size, esp. the 72 inch SINGLE sink countertop... :(. And if I custom made that one, it's expensive. The worst is that I need one 60 inch (I found that this countertop is the only one that's the most typical size) and one 72 inch that's matching right, cuz they're in the same jack & jill bathroom! For the 36 inch countertop for the half bath, the problem is the depth is 1 inch more shallow than the typical tops, so it's 20 inch. And I can't go any deeper because the top is right next to the door opening so 21" countertop won't work! So yes, my house has some strange bathrooms and I figured either we spent more money to hire someone to renovate (but we don't have that funds now) the bathrooms, or we try to make small changes. Of course, I wish I could be as handy as most of the members here then the problem can be solved easily :( Anyways, thanks for all your answers! Please do share if you have any more insights. Thanks again!

If I were to live with this green marble bathroom for a long while, I'd embrace it, as Palimpsest says. My wallpaper would be bold and I'd consider pairing the green with gold, pink, purple and/or navy. Perhaps I'd paint the vanity and wall cabinet. Not sure if I'd use the wallpaper everywhere. Here's a picture from Barbara Sallick's The Perfect Bath. Green and gold powder room. I found these wallpapers that tickled my fancy as a possible pairing for this marble. (I found a bunch of other options but I found them a bit too pricey for a "temporary" refresh.) Amazonia from WallpaperDirect: JewelBox from Spoonflower: Palm Leaves from WallpaperDirect: Justina Blakely's Nana at Hygge & West: If you are tempted by wallpaper, make sure you get samples. There are so many shades of green out there and monitors are rarely true. Another idea that might work: use wallpaper samples as your art. Good luck and please keep us posted!

no 50 voc is as much as some interior paints

The cold tones of your previous choices suggest a cold toned paint to accompany them.
