Corner shelves at Ikea include ones in the Rågrund, Rönnskär, Grundtal, Ivar and Immeln lines. They serve different purposes and are mounted or placed accordingly.
The Rågrund and Rönnskär shelves are stand-alone designs, while Grundtal and Immeln shelves are meant to be attached to the wall in bathrooms. Ivar shelves depend on the side units from that product line. Carousels are available from the Utrusta line.
Ikea also retails a number of corner cabinets, such as ones from the Sektion, Pax and Billy product lines. Customers must purchase shelves separately for the Billy and Pax lines. The shelves for the Pax line are similar to a wardrobe style.
