Best ready mixed plaster for shower room?

[bawbster]

Will be starting this in the next few days, removing peeling paint from the shower room, new skim of plaster and repaint. I'm a novice when it comes to plastering and want the ready mixed kind for quickness and ease of use. What would be the most suitable ready mixed plaster for a shower room.
I have B&Q,Screwfix and Toolstation within a 15 minute drive. Could use Amazon too, but seeing some of the tubs arrive damaged kinda puts me off.

Cheers

I'd use one or two boxes of toupret powder filler for many reasons.
Quicker drying.
Easier to sand.
If you are stuck on ready-mix they are all similar. Just pick one but I'm never keen on them
