Need your help!

I'm making a renovation in my flat, but I have a limited budget. So, my question is: should I spend my last money on this door:

or on new IPhone 5S, cause I also need a new phone!

I need to to finish my renovation and I don't know when will be the next opportunity to change a door, on the other hand I don't know when I will have such a sum of money that I could spend on IPhone...

so, what do you think? Any help will be appreciated!
