Bathroom: Our installer used standard plasterboard - is that ok?

There’s a lot of force on the tiles and plasterboard your behind needs to be solid

I agree the gaps at ends of bath need to be lost. You want the tile sitting on bath lip and ideally the tanking to come down on to bath or you’re relying on the silicone to prevent water getting under the bath (it will happen when the silicone fails and you don’t notice straight away.

Also plan/frame/board(ply) for an access panel to get under the bath to access the waste etc. Secure the panel with silicone, not grout.

And ply behind toilet.

I would likely centre the cubby. You can then reach it from the bath laying position and potentially while showering.

Where it is now, is bad idea. Difficult to reach when laying and too low and close to wall.

We did bathroom and kitchen renovation last year and fitters which we used- they put green plasterboards+applied water sealant, only then tiled. Green plasterboards a bit more expensive, but is worth it.
