I had to mount the catches up on small blocks of plywood to make them work as they are supposed to. There are two versions of the catch, this one and the one below which is designed for vertical fitting.
The small cupboard in the kitchen in front of the sink in the pic below is to store sponges, the plug etc from the sink. I intend on building a plywood box behind it andlining it with the plastic cutofs from the shower lining. This has to have another catch fitted to to the other side when the rest arrive.
The next post will look at the start of the shower/toilet lining.
