I've seen in several places recently where people say the maximum dryer duct length is 25 feet or 35 feet. I don't know where the 25 foot number comes from (maybe an old code?) because IRC M1502.4.6 says 35 feet ...but that's not the end of the story. There are actually 3 different scenarios.Another thing to keep in mind are the fittings and their type, because each can shorten the efficient length of the duct.
DRYER EXHAUST DUCT FITTING TYPE | EQUIVALENT LENGTH |
4" radius mitered 45-degree elbow | 2 feet 6 inches |
4" radius mitered 90-degree elbow | 5 feet |

Is your washer fixed in that location? It can't be pulled out another inch to allow a 4" duct behind it?
Yes, I've been thinking about some kind of clean out at the bottom of the vertical run because it makes sense to do so but I've never seen one. What does a "Cleanup" look like?If longer radius fitting are used, the length reduction is reduced. Also, when there is a vertical rise, in the material exhausted system, a cleanup needs to be installed, because of the promoted condensation.
Yes, I think that's the case with most people. Also, though, dryer safety should be an issue. The dryer transition hose, in most cases I've seen, is a problem. If you want to have maximum room in the laundry, the dryer needs to be pushed back as far as possible but that often times (almost always) means the transition hose gets kinked and becomes a lint trap and an airflow restriction. Both of those things are a hazard. That's why I like the idea of the Dryer Box.I think that in shan2themax's case, she's attempting to reorganize the space for convenience of use, but that the space size will constrain her.
Yes, In my case, I have to move the 30a outlet. The dryer duct needed attention anyway so I'd be re-doing the duct even if I didn't move the dryer.The other difficulty will be the additional length of the connected services, and their protection.
What about one of these? You can put it together so it forms a "U" instead of the "S" pictured.

Another question would be, have you measured the space to ascertain, if, any configuration of venting, will actually fit between the washer and the wall?So this is how the washer and dryer are now. You can see the ventilation exit at the bottom right.

This is the wall I want them on and it is more narrow. So the washer would be on the right and the dryer on the left. I would use that metal dryer vent to go from dryer along the back of washer. The distance left ooen running along the depth of the washer isn't 4". So however deep the washer is would have to be smaller ventilation tubing until it got back to the front of the washer and then it would go back to 4" to the exit.

Ignore the mess.... I did just work 72 hours in 6 days lol
Haha looks like someone was in a hurry.
Yes, I have measured and have put a washer and dryer there in the past to see how much room there would be and it's a tad more than 3 inches. As far as a door, there currently is no door there, however I have a bifold door that I will be putting there once I figure out what I am doing.Another question would be, have you measured the space to ascertain, if, any configuration of venting, will actually fit between the washer and the wall?
Another thought would be, if there is an active door for this space, and it swings in, reversing the swing would then add a flexibility of the need for a narrower vent, while still allowing accessibility.
