Right across CX's The Arrival there is a Plaza Premium Lounge. With your Amex Platinum I believe you get free access. Otherwise it's 200HKD for a shower and 270HKD for a shower and breakfast. Their shower room is slight more right than The Arrival if I remember correctly, but more than sufficient. The lounge area is quite a bit bigger and likely with less crowd than CX's The Arrival.
