Doorway Water Tanks

The Perfect Solution for Tight Spaces
You need to store a large volume of water, but your only access is a standard doorway. This common problem stops many from having a dedicated water supply. The solution isn’t to settle for a small, inefficient tank; it’s to choose a slim tank built for the challenge. At Tank Depot, our doorway water tanks are designed with an ultra-slim profile that effortlessly fits through conventional doorways, giving you access to spaces once considered off-limits for water storage....

All of our freestanding doorway tanks have a width of not more than 30” with some models as slim as 11”. We offer a full line of these plastic doorway tanks from industry leaders like Norwesco, Bushman, and ThinTanks, ensuring a reliable, long-lasting solution that maximizes your space without compromise.
