Toilet/ Shower room

Next job for me was to build the Toilet/shower room, the position of this was governed by the caravan seats bought of eBay, I seem to have forgot to take any picture during this stage which is annoying really as much work went in to it. What the picture doesn't show is I have built a frame first either side then fitted waterproof board on the toilet side and 3mm veneered board on the out side, the door side is 15mm veneered as a shower curtain will cover it.
