RV water hoses typically range in length from 10 to 50 feet. The most common hose lengths are 25 and 50 feet. There are also shorter hoses available, but they are not as common. Hoses that are too long can be difficult to store and can be a tripping hazard, so it is important to choose the right length for your needs. If you are unsure, it is always best to err on the side of caution and go with a longer hose. That way, you will have plenty of reach for all of your needs.
