The kids will enjoy it until then.

What an amazing little invention! The sheer power wielded by those fortunate enough to own one is immense – at least in it's ability to prevent water from flowing straight out of the bath.

The sturdy yet aesthetically pleasing chain that comes pre-attached is simply an engineering feat that feels like it would survive the ages and the test of time. Oh and there's a Unicorn that changes colours as well. Tons if bath time fun for everyone! Well… Everyone except for us tough rugby league fans – we shower…
