It was a 14th win in 18 SCFL premier games for Mike Hamm’s side but they remain six points behind leaders Haywards Heath, who have a 100 per cent record after 17 games.
Stan Bridgman scored two, Evan Hoarty one and there was an own goal as Steyning eased to victory.
The defeat left Shoreham just one place off the bottom.
