Simply Light Designs Bathtub Floor. 30″ x 90″ x 3″ deep. Four 7″ titanium stakes included (0.9 oz for the set). Tiny struts in each corner. Never in the wilds. This was a garage project.

About a dozen pinholes in the perimeter where I added snaps as part of a bug screen experiment. Changed my mind and pulled them. See pics. Corners are sealed.

$45 gets it to your doorstep.
