Unlike inflatable or flexible rubber tubs, this foldable model will probably give you the closest thing to tub-like experience. Although its more expensive than most of our other models, it could be worth the cost if sturdiness and durability is a priority. 

Its foldable design allows it to retain its rigid shape during transport, and its 8.6-inch depth when collapsed makes it easy to slide into narrow spaces. 

Constructed of TPE and and PP material, this tub is also nice and durable, and the manufacturer claims that it can be folded up 15,000 times.
