We prefer the bifolds a LOT. We do not put the bifold on a track at the top, so we can swing it out of the way. To keep it from going into the closet, or pantry, there is a stop only at the top, The bottom of the bifold swings freely, and I do not have to worry about hurting my feet on any track, or getting dirt out of the track either. We are also going to use these bifolds on our master closet. With french door style, 10 lights per panel. We are putting clerestory windows inside our walk in closet, going into a room bumpout which will lead to removal of a pair of windows and the loss of that light source. So we will still have the light, still have the wide closet opening, and we will have privacy as well with no curtains. The bifold french style is sold by Home Depot. Check the brand Pinecroft, which they generally do not stock but do order for you. Plus, you can always mount the doors with separate hinges on either side of a doorway, making them look like a real pair of french doors. I've done that before. Looked nice.

Thank you pal for those suggestions. They are both gorgeous. The chandy is polished nickel so we don't need chrome. I will try to find some less expensive versions of the ones you posted --- or wait for a very good sale. We are going to ask the electrician to leave us extra wire so we can adjust the height. We moved the box down to 7 feet 6 inches, but it can go even lower with the extra wire (or higher). It all depends on what we can find. Carol

You can buy a mirrored medicine cabinet that has integrated LED lighting, which can also offer a nightlight with dinner function. So, you will not only have lighting from your main bathroom, but an additional light source. As for size, you can also get customized sizing where cabinets can be ganged together. Two 12 inch cabinets ganged together or two 15" ganged together would work where you can add lighting as an option and have interchangeable left or right open doors. It gives you alot of storage over your vanity without looking too wide. And if you want to spend the extra cost, you can have them recessed mounted as well. This will make them look flush with wall and less bulky over your smaller vanity. I hope this helps.

Not a hard thing to find, but mostly commercial with a price tag of $800 to $1000. Or you could buy a cheaper hollow steel door from a box store and order a Louver insert for a hundred or two depending on size and install it yourself if you have the basic skills to do so. Google "metal Louver inserts" and you'll find nearly anything you want. If your objective is to supply combustion air for the furnace your openings must conform to the uniform mechanical code for safety reasons and advise following the code. "The UMC specifies that a furnace room should receive ventilation from an adjacent room through two separate vent openings, one of them within 12 inches of the floor and the other within 12 inches of the ceiling. The vents must provide at least 1 square inch of open space for each 1,000 Btu/h total input of all appliances in the room, with a minimum open area of 100 square inches."
