Hi all//this is my first post and Iwish it was a happy one...Just finished of a shower room and had accident with a loose heavy show arm falling onto the white ceramic/pocelain shower base from height!!!.It bounced and left a deep chip maybe 3/4" dia and quite deep...probably nearly complete base thickness??.Is ther any recognised repair I could attemp?Any advise gratefully received as we are out in the spanish mountains,
Regards
