If the hose-to-drain route isn’t feasible, many dehumidifiers come with a built in pump, so it will pump water out when the tank is full. These can go against a hydraulic head, so you could even put one in a basement with no plumbing, and run the drain line upstairs to a drain.

Also, you probably know this, but for anyone else, don’t bother with any dehumidifiers that run on a Peltier element instead of a compressor. They will be slightly cheaper, but they’ll use the same amount of energy for like 1/20th of the capability. They advertise them as “quiet” or “compressor free”, but just don’t do it.
