Ref. 4181 WC Free/Occupied

Tupai · Made in Portugal · Zamak with PVD finishing

The 4181 WC with a free/occupied indicator window — the hospitality and shared-bath specification. The free/occupied indicator window is the hospitality and shared-bath specification — a coloured insert flips with the turn-button so the door reads as available or in use from the corridor. The cleanest sliding-WC hardware in the Tupai catalog.
