Covana Oasis — an automated hot tub cover that lifts into a roof at the turn of a key, with privacy shades and ambient lighting. The sloping roof keeps leaves, rain and sun off the water, and it ends the two-person wrestle with a wet foam cover.

Living with it. It fits most spas without protruding headrests that measure up to 98 inches long, 92 inches wide and 34 to 48 inches tall, with at least an inch of flat surface on top of the shell — bring your spa's dimensions and we'll confirm the fit before you buy. It needs its own power and a level surface to anchor to; we install it with the spa or on an existing one.

Condition. Certified-used: inspected, tested and operated on our floor before listing.

New MSRP: $11,500 (manufacturer's suggested retail price when new). This is a certified-used unit — our price is the price shown.
