We purchased the showerbase yesterday. Over the years we have suffered, and we have heard lots of other stories of the flimsy caravan bases breaking. When a shower base breaks there is much work required to repair and most people (including us) decide to bodge the repair whilst leaving the baser in situ.
And so we looked at more substantial domestic ones. Lots of domestic ones are really heavy which of course is not what we want. But at Wickes we found just the right one. Its made of plastic and foam. Its 1200 x 760 x 45 (all mm). We purchased a straight bath outlet with a fancy gold drain fitting and being 40mm it fits onto a straight 40mm pipe enabling us to get the waste water out. It has got an overflow outlet which we will not use and need to be able to block up but its all looking good so far
