Can I use plasterboard walls in a bathroom?

Recently I have had renovations in my bathroom, which included the installation of a plasterboard wall which is right by the bath. Tiles were fitted to the plasterboard with an adhesive it seems to have been done very neatly and correctly but I am concerned if plasterboard is okay to use so close to the bath without waterproofing beyond the tiles themselves.
The last thing I want is a structurally unsound wall of tiles right next to my bath.
Is this usual to have tiles fitted to plasterboard walls like this or should I bring this up with the bathroom fitter who fitted the wall?

"As a plasterer myself I would suggest either of two moisture boards sold in two sizes, HardieBacker board and aquapanel boards. They are sold in set sizes dependant on the project to be completed. There's a range of plasterboards on the market for any specific occasion e.g. fire, water, insulation and soundproofing."

"Moisture board plasterboard should be used in bathrooms.
But in saying that a lot of houses are the same as yours with normal plasterboard fitted then tiled on top.
Unless the water gets in a gap and as you say the tiles are fitted well you should have no issues.
Hope this helps,

"As long as the plasterboard are the moisture ones, you shouldn't have a problem. The moisture plaster boards are usually a green colour. Just make sure that these were the boards used as they are mainly used in bathrooms and wash rooms."
