The Ideal Standard Concept Freedom built-in thermostatic mixer is a minimalist and contemporary alternative to bar valve showers.The built-in shower valve can be installed outside of the shower area, so you can switch it on and warm the water before getting in for an extra comfortable experience. Based on the Easybox Slim platform, this mixer is designed to fit into a 43mm wall cavity whilst being quick and easy to install, with superior water tightness because of double water sealing throughout.The Freedom built-in mixers have easy to use metal lever handles which means the shower is easier to turn on and off even with movement restrictions such as arthritis.Like all Ideal Standard products, this shower pack has undergone rigorous testing to ensure the highest quality.
