My basement is mostly finished however I recently undertook a project to knock down a wall and build myself a small gun room. I’d like to install a dehumidifier however I don’t have direct access to a drain. There are two finished rooms between my new gun room and the utility room where the sump is.

What options are available where I’m not going to be constantly emptying a tank and walking through finished rooms to empty it?

Going to need a drain feed
Aprilaire 80 is what we use, set and forget except to occasionally clean the air filter

It does not have to be exactly in the same room.   It will work like a sponge "Sucking" humidity from surrounding areas.  (One reason why, when you set one to absolute minimum it never stops because it is absorbing humidity from outside and such.

An adjacent utility room... Is that where your sump pump is?  The basic ~$150 ones from the big box store will work fine and have a nock-out; you can run a hose to have it drain into the sump.

They make dehumidifiers with built in pumps.
Our basement has no floor drain.
Mine came with a 1/4" drain hose 25 feet long. I drilled a 1/4" hole in the corner of a window and ran it outside.

You can use a condensate pump to get the water out if there's no drain

But like said above, I'd just put it in the utility room and it will pull the humidity from the surrounding areas

Does the house have central air? If yes, install a whole house unit with zone control. 2 zones, zone 1 the rest of the house, zone 2 gun room.

my utility room is 2 rooms away from where this new gun room will be. I'm not sure how much sponging from surrounding areas will occur with all those walls between.

I wonder how far that pump will go. I don't think 16' would make it to my sump. I'd have to go up into the ceiling and run it over two rooms before I could drop it down into the sump.

Yes, I have central air, but the house is not set up in zones, I'm not sure how I could just dehumidify that area. Our basement is already quite a bit colder than the main floor. When we had to have our furnace replaced a couple of years ago, I asked about this and the HVAC guy said that since the house wasn't set up with baffles/zones there isn't much they can do to direct heat to just the basement.
