She's being very secretive and dramatic about whatever has happened to kill their budget on the reno. Why build it up and say "you'll find out in the next video" etc?
I was thinking that maybe they had lost their sponsor for the bathroom (think it was burlington?), but then she mentioned that there was something structural. It's big enough that they can't afford to do wallpaper in the bedroom, so must be really big!
I find it a bit strange that they are getting all the most expensive bathroom fixtures for probably free, but then can't afford anything but the "basics" (so-called "basics" being carrera marble and the like) for everything else, because of this new issue.
Also her accent is all over the place lately!
