This was the experience with my room actually, so if you want everything 'new' I'd suggest specifying that at check in so that you are not given one of the partially-renovated rooms, which, while nice enough, do not provide the full 'treatment'. Some Signature rooms have not yet (as of this review) been fully renovated however, and so still have the former countertops and sinks (functional and clean, but fairly old). The hotel's website has some representative pictures of what to expect. My room was also a 'connecting room' to another room if needed. My room (and I assume all of them) also had a HUGE full-length mirror right outside the bathroom, which was nice.

The SIGNATURE ROOMS are a nice upgrade from their previous standard rooms, and all have (or will eventually have) nice new bathroom countertops, tiled bathroom walls, a long desk by the window (or in some cases a nice couch instead), big TV, fridge, safe etc.
