Water storage tanks, also known as water tanks or storage tanks, are essential for households and buildings that require consistent access to clean water. Especially useful in areas with unstable water pressure or for high-volume use, above-ground tanks have become a practical and popular solution across homes, offices, and commercial sites.


Modern plastic water tanks are made from durable HDPE or PE materials, offering high resistance to UV rays, corrosion, and heat. They’re safe for drinking water storage, chemical-free, and designed with smooth inner surfaces to prevent algae buildup and bad odors. Many models are suitable for outdoor use without requiring additional roof coverage.


At OneStockHome, you can choose from a wide selection of tank styles—capsule-shaped, round, or vertical—ranging from 200 to 5,000 liters. We carry top-quality brands such as DOS, WAVE, all with full specifications including volume, material, dimensions, and warranty coverage.


Whether for your home, factory, resort, or commercial building, you can shop confidently for durable and certified water tanks at OneStockHome. Enjoy fast delivery across Thailand and great value for every project.

What sizes do large fibreglass water tanks come in?

DOS LITETITE large water tanks are made of composite material using continuous filament winding, with large external ribs to resist pressure. They do not rust, have built-in legs for easy levelling, and range from 10 to 100 cubic metres in both on-ground and underground versions. Examples of on-ground sizes:
