The Stylish Baku Back-to-Wall Toilet Is Modern, Practical and Perfect for A Family Bathroom. This Toilet choice is a practical, space saving choice, ideally for smaller bathrooms or en suites. A Back-to-Wall Pan is designed for use with a concealed Cistern, usually inside the wall (this item does NOT include a Cistern). The Rimless Technology means there won’t be a build-up of limescale and bacteria, improving cleaning efficiency and hygiene standards, as well as giving your bathroom an elegant feel with the Toilet Design’s Curvaceous and Sleek Lines. The soft-close toilet seat that is provided protects against mechanical damage as well as minimising excessive noise when dropping the seat down.
