I had Amber bath shower mixer taps fitted to my bath a few years ago and the seal / gasket between the taps and bath is now leaking water onto the floor under the bath. The local suppliers I purchased these from say they don't sell these taps anymore and the supplier they put me onto say they don't recognise the taps. Can anyone please tell me are these seals a standard size or can anyone suggest where I can purchase a seal from? Many thanks for any help you may be able to give. Dee
