The white version features sleek, dark cabinetry and trim for a modern, professional look that suits most interiors.
When sold as a “complete system” or “plug-and-play” package, it includes key components like the sump, plumbing, auto top-off, and sometimes lighting and return pumps — depending on the retailer.
