If you want a shower of the future usually is requires a complete gutting of the existing one. Etoile’s thermostatic shower column by Hafro, however, lets you retrofit a shower of the future into your prexisting one and even comes in a format that will work with your shower/tub combo.
Yes, that is a digital display, which let’s you access some tunes as well as turn on the shower’s chromatherapy, a handshower or a trio of hydromassage jets. It comes in glossy white, grey and white/grey lacquer, or in red, lilac or anthracite opaque finishes. I couldn’t dig up the price, but I think it’s fair to say ‘expensive’.
