My parents house is like that, but there’s a wall with a wide doorway into the area with the vanity, so it’s open but also easy to close off by just putting a curtain rail up. It’s also oriented to the room such that if you only use enough light at the vanity to wash your hands for a midnight potty run, it really isn’t enough to bother someone in the bed if you place the bed sensibly. Getting ready in the morning would be trickier if you needed to do makeup and so on so needed proper lighting, so that’s where a screen or a curtain would come in.

Yes I have done that, and it seems everything in showrooms looks just like you've described the one from Pottery Barn, very beat up and not holding up well at all. I do have a coworker that ordered hers from PB, and has had it for 5 years, she is happy with it. But when researching reviews, I've read some awful stuff about their customer service lately, and experienced it myself with a recent small purchase with them. I'm not willing to make such a large purchase and risk having issues with their customer service. I believe another GW member recently posted on decorating about it too. The manufacturer I ordered from has many very good reviews online. It was not cheap and actually cost more than the vanity from PB without the counter. It is solid wood construction with no MDF. I will inspect it when it arrives and report back. We just had some custom cabinetry made in our bedroom, and the carpenter we worked with did a decent job but he was such a pain in the neck to work with. It also took him months to complete our small job because he had so many ongoing projects with other clients. I was hesitant to go that route again for a vanity.

I purchased this Restoration Hardware 36" Hutton vanity and had it in a guest bathroom that was used mostly as a powder room on a fairly regular basis. The vanity was beautiful and the marble top was thick and gorgeous and honed instead of the typical polished. Unfortunately within a few months the doors warped even though we never showered in the room and maybe bathed in the tub once a week at most. Restoration Hardware was good about sending repair people and replacement doors, but even the replacement doors were warped. If I set the doors on a flat surface, they wouldn't lay flat. The repair people they sent (local companies) were frustratingly incompetent. The frame was constructed nicely but the doors were a big problem. For another bathroom we purchased this Water Creation Madison 60" vanity but we only used it for a few months before we sold the house. It seemed only slight less well constructed and was significantly less expensive than the 72" RH version. We could only fit a 60" so the RH option was out anyway. The marble was a nice solid piece and equally thick, but it was polished which I liked less. Overall I felt like the Restoration Hardware vanity was only slightly better quality than the Water Creation vanity. When I've looked at Pottery Barn vanities in the stores, I have been less impressed with their marble tops which seemed to be thin. Hope that helps some.

When reviews aren't exactly as great as you'd like, always look at the return policy. I just took a look at PB's policy and they accept returns within 30 days. As long as it isn't made custom. Another thing to remember is that the "no news is good news" phrase applies to reviews. People who like it/love it usually don't leave reviews. The ones that have something to say are the ones that take the time to submit a review so that they can get it off of their chest. Good luck on your remodel! If you need mirrors, let us know :)
