We have a portable indoor steam room that we wanted to use outdoors so asked Rex to build a cover for it. The steamer is oval and I removed the domed lid and brought it in to Rex along with a couple of drawings. Rex figured a way to minimize the amount of material used and also installed a zipper, a top hatch, and clips to hold the zippered door open. The cover fits perfectly, the price was very competitive, and Rex had the job done ahead of time. We really could not be happier with the job they did!!
