If the flat was built in the 90's disregard all of what I said about different plaster types.
I've never used a one coat plaster so I can't comment, I've heard that even though it's really a DIY product, counter intuitively it's harder to use.
Thistle anything will be fine as its Gypsum based -so works fine with portland (cement) and other Gypsum stuff.
Its important that the substrate is fully dry before you plaster onto it as the plaster sticks by suction and the damp mortar won't have any. Let it dry fully (I know you didn't and started plastering already) then splash it with a bit of water (I know it sounds nuts but its to do with controlling the suction) then plaster on top. Some people PVA the mortar/render first to get even predictable suction.
I would also give a very slight fall to the front of the shelf/lower window reveal/thing so water does run off- you could do this with the tile but as you're tanking you might as well have that draining the right way.
Never used the Bal tanking system - it looks to be pretty good value actually, at the risk of sounding like a Mapei salesman their Mapegum is great, very easy to work with + clean up - its a ready mixed grey latex goop. If you go to a proper trade tile place (where are you?) you can buy all the tape, matting , primer and what not individually. Might cost a bit more but do you have Sora on your bike?
Good luck.
And Dammit "Plumbing is pretty easy" How did that iBox work out?

After 20 odd years doing building work (on and off) I still find plumbing a lesson in humility. I occasionally need my 60 year old Irish plumbing Guru called Seamus, he's only a phone call away.
