This is the Portable Shower/Changing Room from CVT which runs $175. It is super easy to setup, has it's own water bladder and shower head, includes a couple pockets and clothes line, what more do you need? The floor has a mesh section to drain water and the material is thick, reflective and durable. Check it out at SpiritOf1876.com!

PS. The box didn't say shower but they definitely know it's a shower.
