We removed the hard sliding doors on ours and installed heavy drapes. DW sewed 2-sided drapes with fabric on one side to match the LR and different on the other side to match the BR. The fabric absorbs sound instead of reflecting it like a hard door so you have better privacy, and the dog can go in/out of the BR easily without scratching at the door. Drapes also take up less room. I know the hard door is "fancier" but not nearly as practical as a curtain IMO. Unless you are talking about one of those pleated fabric curtains, had one on the previous Sunnybrook and it was crap.
