Float Tank- 3D Modeling - Autodesk Inventor 2015

I want to make a blow up Float tank. [login to view URL] This is just a tent to show you the idea. This is what I want to build as blow up [login to view URL] The floor would be blow up as well. The floor would have 5 speakes placed into it. There would be an in and out to hook up a pump for return and suction. There would also be plastic hooks in the roof to instal LED lights if needed. Or even LED lights in the structure. It needs to be light proof. Door with zipper. The room needs to be round as that allows water mist to go down the sides rather than fall on someones face. Size 8 feet long, 5 feet wide depth for water 20" and aout 5 feet high. Please see Attachment basic idea. Hope this helps. The whole thing needs to be an air frame. I forgot the depth of water. about 18" or 40cm I think. This will have about 1200lbs of salt added to the water.
