What size aquarium sump will fit inside your stand?

Height rules first. Four ESHOPPS RS models and Bashsea's two 10 in-wide sumps stand 14 in tall; others stand 16 in.

ESHOPPS gives skimmer chamber sizes; Bashsea gives operating water levels. Use your skimmer's depth guidance.

How the comparison works

Your choices are compared with each model’s product details. A missing or conflicting value stays unknown and cannot satisfy a choice you select. The starting order helps you browse; it does not rate real-world performance.

Source dates appear with each link below. A source date does not confirm today's price or stock.

Cabinet access can rule out a sump before chamber size does

External lengths range from 18 to 44 in and widths from 10 to 20 in. ESHOPPS Royale is at the large end of both ranges; Bashsea Bio-Fuge includes narrower configurations. Measure the cabinet interior and the opening through which the sump must pass. Leave space for plumbing and maintenance rather than treating a footprint match as a complete installation plan.

Fit the equipment inside its intended chamber

The Bashsea Bio-Fuge configuration at 24 in long has a first section measuring 10.5 in by 9.5 in and a water-depth range of 4 to 8 in. ESHOPPS Royale has a skimmer chamber measuring 19.5 in by 14 in. These are measurements of specifically named sections; exterior width cannot substitute for either chamber’s usable space.

Compare your equipment footprint and operating water depth with the exact layout, then account for access to remove it. The sump enclosure and chamber dimensions here come without a plumbed system or an overflow-behavior assessment.

Before you buy

Will a sump that fits the cabinet go through its door?

Not necessarily. The filters compare the body with the space inside, and a 36 in sump may still need tilting through a narrower door, so measure the opening too.

Why don’t the chamber sizes line up across brands?

ESHOPPS names a skimmer chamber, while Bashsea numbers its sections and adds water levels. Treat them as different measurements, since a Bashsea section 1 isn’t automatically a skimmer chamber. Inside, ESHOPPS gives skimmer chamber sizes and Bashsea a water level (4 to 8 in or 5 to 9 in), which matters if your skimmer needs a set depth.

Can I work out water capacity from the outside size?

Not safely. Outside dimensions include walls and baffles, and the water that drains down when the pump stops has to fit on top of your running level. Size for drain-down from your own system, or a power cut could overflow the sump.

Why is there no gallon rating?

The RS-300 page lists inconsistent gallon and liter capacities, and some compartment conversions disagree with the inch figures, so volumes were left out for every model.
