No such thing as wallpaper for floors, but there are a few good solutions for water resistant flooring. Pvc, vinyl, linoleum, epoxy or polyurethane paint, for example. I see you live in India, I have no idea what products can be bought there.

Cost is a factor also between papering and paint. 20 years ago, I painted and wallpapered everything myself. 10 years ago when I moved and bought a condo, I hired the papering and I did the painting. Last year when I downsized, my handyman and I just did the painting. No paper. I have found that at my age papering is too much for me. When I get down I can't get up and when I am up it feels too good to get down :>)

Some great advice there! You're very right - it is tricky to decide on prints and colours when there are so many to choose from. If you are still looking for inspiration, you can see thousands of images of different wallpaper styles here. Once you've found the styles you like, you can also save them to your own ideabook, to look back over whenever you want. If you need help with this, let me know!
