I lost my shower

i bought me a animated sexgen shower.
By removing it from my house - rightclick, take - i lost it! It´s definitly NOT in my inventory. It´s still 3 says ago. Where can i get it back?

First thing to do: clear your cache (under Preferences > Network), and relog. It's the bog-standard Help Request answer, but it does tend to fix things.

Otherwise, is your shower in your Lost and Found folder? In the trash?
Start a search in your inventory with part of the name of the object. It's probably called "Shower" something or other. Maybe it has been packed away in an inventory you haven't checked yet.
