Metal Pergola
A solid corrugated metal roof gives complete rain cover and full shade, and the steel frame can stand freestanding beside the spa or attach to the house.

A spa gets used far more when it has a roof over it. Rain, frost on the lid and a neighbour's upstairs window are the three things that stop people getting in, and the right structure deals with all three.

Prefer it bright? Polycarbonate roof panels let through 25–88% of the light depending on tint, so you can soak under the stars on a clear night with a clear panel.
Retractable outdoor blinds close off one or more sides for privacy and wind, with shading options from 2% to 20% and beyond.
