Detail 01
18 in.
Head size is the shell diameter, not the depth. An 18-inch drum takes an 18-inch head, whatever its depth.

Independent shopping perspective
An 18-inch tom head from Aquarian's Performance II line. A low-cost replacement for a floor tom that needs to sound controlled rather than exotic.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Head size is the shell diameter, not the depth. An 18-inch drum takes an 18-inch head, whatever its depth.
Detail 02
Built for tom tension ranges. Snare and bass drum heads are constructed differently and are not interchangeable.
Detail 03
Aquarian's general-purpose tom head. Sits between a bright, thin head and a heavily muffled one, so tuning stays predictable.
Detail 04
Covers one side of one drum. Re-heading both sides of a four-piece kit means buying eight heads.
Detail 05
Priced as a consumable. Heads are wear parts and get replaced, so cost per head matters more than on hardware.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes. An 18-inch head fits an 18-inch shell regardless of the drum's depth. Measure across the shell itself, not the outer rim of the old head.
It can go either side, but it is made to be struck. Most drummers put it on top as the batter and leave a thinner head on the bottom.
One. Each drum takes one head per side, so re-heading a full kit means buying several.
A drum key. Everything else you need is already on the drum, since the existing hoop and tension rods are reused.
