1. Without using the overflow cover, fill the bathtub to the level of the overflow drain, so that water is escaping through the overflow drain.
2. Place the cover on AND briefly lift the bottom drain stopper, this instantly creates a strong vacuum seal.
3. Top up the water level to the very top…. if you dare!
4. Enjoy your deeper bath!

Helpful tips to avoid accidental flooding :)

  • The overflow cover should never be used while filling the bathtub unattended.
  • The cover is designed to work when the water inside the tub escapes through the overflow drain and creates a pressure differential.
  • Only place the overflow cover once you are inside the bathtub and the water has started to escape through the overflow drain.
