Condensate Disposal Options on a Dehumidifier
Short answer: Dehumidifiers get rid of collected water 3 ways on a listing: a bucket you empty, a continuous drain hose that sends water to a floor drain by gravity, and a built-in pump that can lift water to a drain above the unit. Read the disposal words before the capacity, because disposal decides where the unit can sit. Ask the maker for pump lift and hose length.
What condensate disposal means on a listing
Condensate is the water a dehumidifier removes from the air. The U.S. Department of Energy defines a dehumidifier as a product with a refrigerated surface that condenses moisture, a refrigerating system, a fan, and "a means for collecting or disposing of the condensate." On a listing, that collecting or disposing means appears as words: bucket, drain hose, continuous drain, gravity drain, pump, or built-in pump.
A title may name 1 disposal method or several. A model may carry the word "pump," another "drain hose," another just "bucket." The disposal words matter because they decide where a unit can be placed: a bucket-only unit needs a person to empty it, a gravity drain needs the hose end lower than the unit, and a pump can send water up to a drain that sits above the unit. The comparison between gravity drain and pump is covered in the article on gravity drain versus pump.
Questions about moisture and mold in a home are covered by the EPA and CDC pages in the sources; this article reads the listing words only.
Bucket-only: emptying by hand
A bucket is the standard disposal method on portable dehumidifiers. ENERGY STAR describes most portable units as using a removable plastic bucket and warning lights to indicate when the bucket is full, with an automatic shutoff so the bucket does not overflow. The listing may say "bucket," "tank," or "removable water tank," and the "bucket full shutoff" or "tank full shutoff" words describe that automatic stop.
For a rental apartment, a closet, or a bathroom, a bucket-only unit can be the simplest choice. The emptying routine is described in the unit's manual, and a person carries the bucket to a sink or drain. The shutoff mechanism is explained in the article on bucket full shutoff.
Continuous drain and gravity drain
ENERGY STAR notes that some dehumidifiers come with a fitting that allows you to hook a hose directly to the bucket, which can then be directed into a floor drain or sump pump, so there is no need to empty it. On a listing, that feature appears as "continuous drain," "gravity drain," or "drain hose."
Gravity drain means the water flows out through a hose when the hose end sits lower than the unit. The hose may be included in the box or sold separately, so check the listing and the maker's page before planning a setup. The manual describes where the hose goes and how to keep it clear; this article does not cover routing a hose through walls or floors. The limits on hose length are a maker question, explained in the article on drain hose length.
A finished basement with a floor drain is the usual situation for a gravity drain. A garage or workshop with a drain at the same level also suits it.
Built-in pump and pumped drain
A condensate pump is a small pump that lifts the collected water so the drain can sit above the unit. The listing may say "pump," "built-in pump," or "with pump." ALORAIR, for example, names one of its units the Sentinel HDi90 with the words "(Built-in Pump)" in the product name, which is how disposal words appear in real titles.
A pumped unit is useful in an unfinished basement with no floor drain, where the water needs to reach a sink, a laundry standpipe, or a drain on a higher level. The pump adds a part to maintain, and pump maintenance is covered in the article on condensate pump care.
The maker's page states pump lift height, and the lift spec is a maker question covered in the article on water lift pump spec. This site gives no figure because no measured lift data exists in the catalogue: the numbers live on the maker's page.
Questions to take to the maker's page
Before a purchase, take the disposal words from the listing to the maker's page and ask: What is the pump lift height? What length and diameter of hose does the unit accept? Is the hose in the box or sold separately? Does the bucket full shutoff still work while the pump is running? What does the manual say about where the hose end goes?
The answers determine whether a unit fits the room. A listing that says "pump" but does not name the hose length is not enough information for a finished basement with a drain far from the unit. The general review process on this site is explained in the dehumidifier reviews guide.
Choosing disposal for your situation
Match the disposal words to the place where the unit will sit. A finished basement with a floor drain nearby suits a continuous drain or a bucket. An unfinished basement with no floor drain suits a pump. A garage or workshop with a drain at floor level suits a gravity drain. A closet, bathroom, or rental apartment suits a bucket-only unit.
For a small business back room or a job site, pump models appear often in commercial listings because the drain position varies. The commercial dehumidifier guide compares stated details, including disposal words, model by model.

Questions
What does "continuous drain" mean on a listing?
It means the unit has a fitting where a hose can be attached, and water flows out through the hose by gravity when the hose end is lower than the unit. The hose may be included or sold separately.
What does "pump" mean on a dehumidifier?
It means the unit has a built-in condensate pump that lifts the collected water so the drain can be above the unit. The maker's page states the lift height.
Is the drain hose included in the box?
The listing does not always say. Read the box contents on the listing and the maker's page; a hose can be a separate purchase.
Can a unit empty the bucket and run a hose at the same time?
Most portables work in 1 mode or the other. The manual describes how to switch from bucket to continuous drain.
Do whole-home dehumidifiers have a bucket?
Most whole-home units are equipped with a drain only, which is routed to a floor drain or condensate pump during installation by an HVAC professional, per ENERGY STAR.
What is "bucket full shutoff"?
It is the automatic stop that keeps the unit from overflowing when the bucket is full, described by ENERGY STAR for most portable units.
