The wallpaper full of famous painting seems kindof hip to me. I'm not big on the antlers myself but, I don't know that it feels "dated". That said, it's your bathroom that you are putting a lot of work and money into and are going to live with. If you love it, I say go for it!

I like it until I see it. It’s fun but too creepy for me. I think it could spook young ones.

Interesting...but I fear I would grow tired of it quickly. Also, if you ever intend to sell the house, it could be a turnoff for some buyers (you know, the kind who rule out buying a house because they don't like the shade of yellow in one bedroom).

Wallpaper is easily enough removed these days. And it's just a powder room.

No, it doesn't feel "dated". It feels like something I'd enjoy as a guest:) if you know you'll enjoy it as a homeowner-even better. It's a powder room, perfect place to have some fun.

(thank you for the link btw..I liked the hopscotch))
