My camp has french doors into the master bath. Why???? We only use the one door. The other is always secured in place. The only time it is opened is to clean the floor underneath it.

Function, thanks. How wide is each door?

Those are very narrow openings, so there is probably not a standard double door available. So you are already talking about custom doors. What is driving you to consider this? Is there a functional reason or just aesthetic? Would you be able to install a pocket door instead?

We rented a house while building and the front door and master bathroom doors were double doors. I don't find anything positive about double doors in those locations.

In the new house all interior doors are 36" wide, which we really like.

Thanks, Kardrewspa. We would like to replace the hollow doors with solid doors, and since they are not standard sizes, we would probably need to get custom doors whether we go with single or double doors. The current doors open into tiny bathrooms < than 34 square feet, so it is difficult to maneuver in the bathrooms. Once the door is open, one must squeeze around to close the door or to get to the tub or shower.

A pocket door would necessitate losing 2" from the adjoining bedrooms because the frames are only 4.6" deep (and the contractor wants $5K per pocket door). In one, it would necessitate replacing doors to 2 sets of double closets. In the other, it would jut out into the room and block a large window. That space hasn't been demoed yet, so we may not have enough space inside the wall. The powder room currently opens into and blocks a narrow hallway, which is not ideal, but cannot be reversed because the room is only 17 sf in an L shape, impossible to navigate if reversed.

And you think any of this will be under 5K? Stick with what you have or find a bigger house to move into.

Thanks, chispa. If we could make the openings larger, we would. Unfortunately, that is not possible in any of the locations.

A double entry door works best when you are entering a large space. In addition, you do not want to have to open TWO doors when you are rushing in to use the facilities ;) !

Like chispa, while we were building we rented a house that had double doors into the master bath. I hated it!

Can you do this? Sure. Any lumber yard can order doors that match your existing doors but that are half the width, they can be trimmed to fit your slightly off width. One door will have to have a pin that locks it down to the floor or up into the jamb so it can be secure for the other door to lock to it. Meaning when you want to lock the door you pull one door shut, slide a bolt to lock that door, close the second door, lock it to the first. 100% not something I would want. Your house your party

You cannot get into the bathroom with only a 15" opening. You have to use both doors, every time. Also, they take up twice the room when open as does a single door, so your actual opening is reduced even more.

The opening is really too small to do paired doors you walk in and out of, as opposed to a closet or semthing.

The locking mechanism will be cumbersome.

Sound transmission will be higher than with a solid hinged door unless there is an astragal on one door which means the order of how the doors open and close will be specific.

I would only do such a thing with an ensuite bathroom, I would not expect guests to deal with something like this and compromised privacy. However if it were an ensuite bathroom and I was not overly concerned with privacy I doubt I would even put locks on it. In our house a closed bathroom door is not an invitation to open it, so generally it's not necessary for us to use locks to keep other people out. (But the doors do have them)

The bathroom off my bedroom is 4' X 5'. The std. door swings into the bedroom. The house next door has 'double doors' that I describe as saloon swinging doors. Yes they have to push on each one every time and the doors are always shut BUT they didn't lose space to a pocket door or have the door in the bedroom.

And think about where your light switches would need to be.

For elisamama. A special invite for you!

In a custom home we built, both the MBR and the MB had a set of small double doors, but the opening was larger than yours. They don't need anything on the floor to keep the shut. A ball catch is used on the top of each door. All of the doors had dummy knobs (levers in our case). Neither set of doors locked or had wood strip to cover the tiny opening, but I suppose a strip could easily be added. Switches were not an issue in either location. Doors were left open most of the time.

You can certainly have the doors bores for a lockset for the active door as long as the stiles are wide enough. The inactive door would need to have surface bolts of some type for the lock to work as designed. As far as the space between the doors, you can use a wood astragal to cover that, it would be face mounted to the inactive leaf. This all being said, doors this narrow will need to have both opened to be passable and they will be a pain in the a** to use constantly, quite honestly.

since they are not standard sizes, we would probably need to get custom doors whether we go with single or double doors

28" & 32" doors are standard and likely the size intended for the existing steel frames. Probably no need to go with custom.

As mentioned, if possible, look into reversing the swing to gain more usable space in the bathroom. My master bath door was changed by a previous owner to swing out into the bedroom to better utilize the space.

Our house came with double doors between the kitchen and foyer, and kitchen to basement stairs, and dining room to family room, and dining room to living room. (There used to be double doors between the living room and foyer, thank goodness someone removed THOSE, as it’s a wide opening and those doors would really take over the living room.) The doorways are standard 31.5” widths, so each door is 15”. The good news is, it is easy to keep all the doors open because they don’t block anything too much. The bad news is, IF the doors are closed, it takes two hands, or a hand and a foot, to widen the opening enough to go through.

Keep in mind, if there are walls on the sides, one or both doors won’t open all the way, narrowing the doorway.

I lived in a house with double doors to the master bath. But, they led to the vanity area, and the tub and toilet were off to the left of the vanity with their own door, and the closet to the right of the vanity with its own door. The double doors to the vanity area were open nearly all the time, but then I lived by myself so I didn’t care.

Our last house had a hall bath where the door opened in, but the bath was so small it didn’t open all the way, not in either direction. When we remodeled it, we considered having the door open out, but that would block the hall. We ended up with pocket door. I suppose we could have considered double doors, but the privacy would have been less than even the pocket door, and a pain to use, besides.

l don’t recall installing the pocket door necessitating making anything smaller.

And yes, the light switches. The kitchen switch is behind a door. We also have double doors from kitchen to dining room (someone had stock in double-doors when this house was built!) and the switch is behind the door. What a pain. At least the kitchen door is narrow enough that it isn’t so bad to reach around and hit the switch, and the kitchen windows and flow-through light anyway. The dining room, well, it’s just a bother, especially when at the table and you want to dim the chandelier, having to move the door to get to the switch.

Would a bifold door work at all? (Please don't yell at me if this is physically impossible. We have one into our small office but I have no idea what size the opening is and was too lazy to go downstairs to measure.)
