FAQs

Casa Milano offers a wide selection of premium sanitaryware for modern residential, hospitality and commercial bathrooms. The collection includes wall-hung WCs, rimless toilets, bidets, wash basins and complementary bathroom fittings from leading international brands, with designs ranging from contemporary minimalism to luxury statement pieces.

A rimless WC is designed without the conventional inner rim around the toilet bowl, reducing areas where dirt, bacteria and limescale can accumulate. This makes the toilet easier to clean while allowing water to circulate efficiently around the bowl during flushing. Casa Milano offers several rimless wall-hung WC options for modern bathrooms.

Yes. Wall-hung toilets are particularly suitable for contemporary and space-conscious bathrooms because the WC bowl is mounted above the floor while the cistern is concealed. This creates a cleaner, more spacious appearance and makes the floor around the toilet easier to clean. Casa Milano offers wall-hung WCs in several compact sizes and designs.

Consider your bathroom dimensions, installation requirements, plumbing configuration, preferred style and available space before selecting sanitaryware. Check each Casa Milano product page for dimensions, mounting type, material and technical specifications. Technical drawings and specification sheets are also available for selected products to help architects, designers and homeowners plan installations accurately.
