How to setup diaper changing area without the changing station?

I Believe 🌈
Our bathroom has a reasonably sized (see picture) platform which i believe will fit the changing pad. I am not sure if just the changing pad is enough or is there an option to buy a wooden base to prevent the changing pad from slipping? Many people I have spoken to recommend a changing station which comes with its own storage and can be kept in the nursery or bedroom. However I am not keen to add an extra furniture hence looking for a space efficient but safe +stable solution. Any recommendations?
