GE Opal package choice
GE Opal Ultra: standard tank, XL tank or no tank?
The Opal Ultra name covers different counter packages. Compare the tank, collection bin, output conditions and working clearance before choosing a finish.
Three water arrangements, one small collection drawer
GE's XPIO13SWSS, XPIOX3SZSS and XPIO23SWSS are nugget-ice Opal Ultra configurations with different water packages. XPIO13 includes a standard 0.75-gallon side tank. XPIOX3SZ is the one-gallon XL side-tank family. XPIO23 is supplied without a side tank. The tank changes how often you replenish water; it does not enlarge the listed three-pound ice bin. Don't combine a tank accessory's capacity with the bin or call the assembly a direct water-line connection—the linked manual describes a reservoir and side-tank feed, not household plumbing.
Use the complete package width
GE lists the XPIO13 and XPIOX3 side-tank configurations at 13.43 inches wide, 17.5 inches deep and 16.5 inches high. The no-side-tank XPIO23 is 10.5 inches wide in GE's listing. The manual asks for four inches at each side and behind the unit for air circulation. Those clearances make the needed countertop area much larger than the body measurements alone. Also leave room to open the front drawer, handle the water tank and reach the back drains. A tight 13-inch shelf is not made suitable just because the ice maker is sold as a countertop appliance.
Compare output under the conditions actually stated
GE publishes 38 pounds per day at 70°F room air and 60°F water, and 32 pounds per day at 90°F air and 70°F water under DOE conditions for the reviewed Opal Ultra models. Those are maker claims, not independent production tests. A side tank can reduce refill interruptions but cannot erase the warmer-condition difference. For a warm room, compare using the 32-pound claim. If what matters is one large pile ready at once, the three-pound bin—not the daily rate—is the more useful starting point, and it still does not provide powered frozen holding.
Choose around your routine
The XL tank is the reasonable fit for frequent nugget-ice use when fewer sink trips are worth an extra container on the counter. The standard XPIO13 tank can suit someone who wants the same general arrangement with a smaller water reserve. The tankless XPIO23 removes that side object and has the narrower listed body, but its reservoir still requires manual filling. None of the three should be chosen to meet an essential direct-plumbing requirement without an exact manufacturer connection document.
Ownership also follows the package. GE's Opal manual says to keep the side tank level with the machine, hand-wash the tank and its valve, reconnect its tube as illustrated and drain before relocating or leaving the maker off for an extended time. A tap on Clean handles a rinse or sanitizing cycle; holding it starts descaling. These cycles do not make the bin, drip tray or water path maintenance-free. If the version is an earlier model, verify its exact tank, filter and drain parts instead of assuming that an Opal name guarantees a complete package.
One status caution applies to the one-gallon XPIOX3SZ finish family: GE's sales pages say out of stock and no longer manufactured, while the Owner Center shows a May 2026-to-present manufacturing range. That conflict is why the XPIOX3SZ review is treated as an earlier reference rather than a default current recommendation. Compare its exact finish only after confirming the seller's model label and supplied tank. GE's XPIO13SWSS, XPIOX3SZSS and XPIO23SWSS product pages and the shared series manual are the primary references.
