Cover to 'Dutchtub Loveseat'

For quite some time I am a fan of the funny Dutchtubs. Here in it bathes with one or more loved ones in the great outdoors. Or simply in the home garden, of course.

As of today, I have some accessories for the Dutchtubs.

For the loveseat, I discovered this clever cover: a specially insulated lid that makes the water heat up faster. Works like cooking: When a cover is on, the water boils faster.
