SPT vs ZLINE Key Differences
Installation type
The ZLINE model is a 24-inch built-in dishwasher designed for standard cabinetry. It requires professional installation to fit into your kitchen layout. The SPT unit is a countertop dishwasher.

Capacity

Width

Noise level
The ZLINE dishwasher operates at 51 dBa. This level is considered quiet for a built-in unit. You can run it during conversations without significant disruption.
