If your bathroom will be undergoing a partial renovation, then you should utilise the advice given here.
Detach and remove your shower screen from the bathroom
Good-quality shower screens can last for decades. If your shower screen is in great condition and is not going to be replaced when you renovate, then it is best to detach it from the tub or shower cubicle to which it is connected and to then take it out of the bathroom before beginning the renovations. Removing it from the bathroom area will completely eliminate the risk of it getting splattered with wet grout or paint (whereas leaving it in place and covering it with a sheet will merely reduce this risk). This will mean that you won't have to face the arduous task of removing these substances from the screen whilst trying not to damage it.
It will also mean that you (or your decorators and plumber) won't have to be constantly vigilant when using hammers near the shower cubicle or bathtub in order to avoid striking the screen and shattering it. Additionally, if your renovation plan includes changing the tiles or faucets around the tub or cubicle, then the removal of the screen will enable the person who does these tasks to come and go from this area much more easily.
Take extra care when wrapping the immovable features that are not undergoing renovation
If there are features that are too difficult to remove (like the toilet or a large bathroom vanity unit that is connected to a wall) which you plan to leave in place and protect by wrapping them up, it is important to do this properly.
For example, you may want to cover these items in bubble wrap to ensure that they don't get scratched by discarded tiles, splattered with waterproofing liquids and wall paint or broken if tools are dropped on them. If you'll be doing this, you should buy extra-wide bubble wrap so that one long sheet of this plastic will cover most or all of the object you're placing it on, without you having to leave any openings into which sharp pieces of old tiles could fall or drops of paint could seep in (which could happen if you use narrower rolls of bubble-wrap, which would need to be wrapped around each object multiple times to fully cover it).
Additionally, you may want to use some twine to tie tarp around these items; adding this as a top layer will further reduce the risk of sharp tools falling on or being accidentally laid upon these bathroom features, as whilst tarp lacks the shock-absorption qualities of bubble-wrap, it is less likely to tear if exposed to the sharp edges of any implements.
