bathroom remodel question ..

No not pregnancy related but get best responses here! Lol pic of bathroom currently where I'm moving.. HATE the floor so going to try a little diy... Shower curtain is the color in second picture with a black rug... Which flooring of the 4 options on last pic would match best? Or do i need to paint this dang cabinet too? Or the gray flooring on bottom? Or is that to much gray ? Need help cause husband is none !
