Types of Water Tanks Explained: Overhead, Loft, Capsule, and More

By Team Skywell · September 7, 2026 · 2 min read

Short answer: use an overhead tank for gravity-fed supply to the whole house, a loft tank above bathrooms for steady pressure, a capsule tank where space is tight, and a stainless steel tank wherever drinking purity is the priority.

Key takeaways

  • Overhead tanks are the house’s main reservoir: choose these first.
  • Loft tanks give strong, steady bathroom pressure without pumps.
  • Capsule tanks fit basements, crawl spaces, and narrow terraces.
  • Stainless steel suits drinking supply; plastic suits everything else.
  • Most homes mix two or three types. That is normal and smart.

Overhead tanks

The classic terrace tank. Water is pumped up, then supplies the house by gravity. Choose three-layer, UV-stabilised plastic or stainless steel. Our classic and marble-finish ranges cover 500 L to 5000 L.

Loft and bed-type tanks

Low-profile tanks that sit inside attics and lofts above bathrooms. They keep pressure steady at the shower even when the main tank is mid-refill. Ideal for homes with weak terrace access.

Capsule tanks

Horizontal, space-saving tanks for basements, crawl spaces, and narrow terraces where a round tank simply cannot stand. Same food-grade interiors as our classic line.

Stainless steel tanks

The premium choice for drinking water: rust-free, algae-free, 10-year warranty, in 500 L to 5000 L, vertical and horizontal. See the full stainless steel range.
