A bottom connecting portion 163 extends from the lower side of the intermediate sidewall portion 161. The bottom wall 15 includes a first bottom portion 151 and a second bottom portion 152. The bottom connecting portion 163 is located between the first bottom portion 151 and the second bottom portion 152 and connects the first bottom portion 151 and the second bottom portion 152. Because the bottom connecting portion 163 is flexible, the first bottom portion 151 and the second bottom portion 152 can be folded. Because the upper connecting portion 162 is flexible, the first left portion 141 and the first right portion 142 can be folded. Because the middle sidewall portion 161 is flexible, the upper sidewall 14 and the bottom wall 15 can be folded. Here, the middle connecting wall 16 is made of flexible silica gel, and the upper sidewall 14 and the bottom wall 15 are rigid. The above structure further reduces the volume of the collapsible bathtub, making it easier to store, pack and transport. Here, the upper connecting portion 162, the bottom connecting portion 163 and the middle side wall portion 161 are integrally molded.

[0018] In this embodiment, the foldable bathtub further includes a sealing plug 5. A water outlet 18 is installed at the bottom of the bathtub body 1.
