Our yard is too small for a built-in swimming pool, so we purchased the largest hot tub we could find and had the 10 x 10 patio gazebo installed over the hot tub (the tub sits on a concrete pad & has a deck built off one side of it).  The metal roof is almost a perfect match with the metal roof on our home. We planted some lovely queen palms near the hot tub and it looks like an island paradise.   Everyone loves it (and my neighbors in the two-story house behind us can't see us in the hot tub!)  Great purchase.
