Plug Stopper

We have just had a new bathroom which was great, but then we noticed that if moved around while in the bath you could accidently drain all the water. this due to the style of the drain plug and its location (centre of the bath). So I decided to create a method to stop this, I used generic tpu, needs to be flexiable, and designed a small gadget which will slide under the top once it is in the closed position, this then prevents the drain from being pressed down to the point that it opens the drain. Once you have done just pull the stopper out and all works as normal.
