OXO Good Grips® Tub Stopper 1 "Doesn't work if surface not flat (small bath)" Laura 08 September 2017 I have a small bath and the area around the plughole is not flat. Again this product does not work in this situation. However Lakeland gave a no-quibble refund - thank you. A note from the team Thanks for placing your review.
