The supplied Reddit result could not be extracted because it returned a verification challenge. The usable source is the fan furniture list, so this page focuses on a safe in-game lookup method rather than asserting a shop location that may have changed.
Search by the fixture category
Open the furniture or appliance purchasing interface and search for bathroom-related fixtures. Compare the item name, category, price, and availability with the current in-game catalog.
Check the business requirement first
If you are buying a stall for a specific business, review that business's setup requirements before purchasing. This prevents adding a fixture that looks correct but does not satisfy the required item type.
Keep a version note
Furniture catalogs and store availability can change. If the item is absent, use the current map and catalog filters rather than relying on old community posts.
