Give it some time and more knowledgeable people will come and answer. I know a red-taged item cannot be put in service. It would be against the law for someone to turn on your fan, or to hook up electrical service to it if it were not hooked up already. For a professional, it would likely be a licensing issue. For you, it is an outstanding violation that probably means you cannot sell your house. There is essentially a lien against your title if you continue to ignore it. These are all my guesses, based on things I have read. I googled, "What happens if I don't fix a red-tag violation in my house" and found one town said this: "Red tags must be recalled for inspection and paid, if applicable, within seven working (7) days. Failure of the contractors or owner/builders to request and receive re-inspections before proceeding with additional work may result in disciplinary action or a fine against the contractor or owner/builder." If you live in an incorporated city or village, go to the website, there is likely a FAQ with lots of info and maybe your question is answered. If you are not in an incorporated area, go to the county site - whatever governmental entity sent out the inspector. See if you can figure out the answer. Or just call the permit office and ask what happens when a red tag is ignored.

It is a little overwhelming to start. You have the functionality aspect of planning the bathroom and then the fixtures/look aspect. I definitely find it less exciting to research the functionality options but that usually ends up being where I wished I spent more time. For the functional - some of the things I think I remember is making a decision - do you want your vanity standard at I think 30 inches (this is our hall bath) our taller at 34 1/2 (our masterbath), or even taller at 36". The 34 1/2 is definitely more comfortable for me than when I use the 30" tall vanity in the hall. Someone else made the point of working around the pipes with the drawer so you can gain more storage. I wasn't able to get that in the cabinet line and every time I see the false drawers I think of what can't be stored there. You may also want to think, where else can you get more storage. In one case - had a niche build in the wall and added a glass shelf - this it the side wall that is next to the vanity. With the fan - someone mentioned making sure it vents properly thru the roof. In addition to that, you may want to see if a skylight is possible and how much it would cost. I wasn't a big skylight person (worried it would leak), but now I love having the extra light in the bathroom and extra ventilation. Not sure if you decided on a grab bar for the shower. Also if you are going with a shower niche (they have the plastic molds that can be tiled into the shower - I think that is easier for contractors to work with, but it is defined sizes) For the fixtures - I used faucetdirect with no problem and did a lot of online shopping. Where I had problems was with the valves and drains and I am not sure if that was because I didn't utilize the sales people enough or that you had to be familiar with my setup specifically to know which product. In one case, the drain wasn't quite right even though it was recommended to go with the tub. The contractor made it work. In another, luckily my contractor told me to order the pop-up drain for the sink. That's another one that doesn't necessarily match for me online. Since my faucet controls were in the wall, I needed the popup drain in the sink. With the valves, in a custom shower, I didn't do my homework on the 1/2 inch versus 3/4 inch and that I needed a transfer valve to switch between the handheld and the main shower. Last thing - I think the tile from HD or Lowes is fine. Tile can get pricey and that is where I wish I had found something that looked nice but was less expensive. If you do want to splurge on something - maybe look into the Benjamin Moore Bath and Spa line paint. It is made for bathrooms and has a matte finish.

Thank you David! When having this house renovated post purchase, much of the bathroom was gutted and the sink I had installed is one I bought new some years before and was waiting to use (American Standard Standard Collection Console sink with oval glass shelf.) Because the works underneath are totally exposed I bought the best chrome P-trap and fittings a local plumbing supply house had. In a month or so I'll have my plumber back to install a pump for my utility sink, and he will need to add another vent stack I believe, so I'll have him see if the sink is connected to the bath vent, and if the vent has any blockage. I'll ask him about the air admittance valve - thank you so much for that information!

Code is the worst that a builder is legally allowed to get away with. Just because something meets code doesn't mean that it's good or what you want. Code or not (and window or not) you want a powered exhaust in every 3/4 or full bath (and IMO every 1/2 as well). The only exception I would make is in a local where windows are kept open nearly 100% of the time so that the space is effectively outdoors.
