Shower isolating valve - where to put it?

What kind of shower?

Tank outlet if all else fails.

Sorry, it's an electric shower fed straight off the mains. There is already an isolating valve on the main pipe that feeds the shower but that also feeds the bath, washbasin etc., and I think a separate isolating valve is necessary for the shower.

How many valves? You start with plural then drop to singular. The obvious is answer is where they are accessible...

Or behind an accessible and removeable access panel.

I have the pipework for mine emerging from the wall under the bath, where there are isolating valves which you access by removing the bath panel (actually, hinging it up in this case, as it hangs on hinges from a piece of 3x2).

I wouldn't worry about it. If you need to fiddle with it, you turn the mains off. It's not as if there is a couple of tons of water in a loft tank you'd have to drain first (been there...)

We already had one under the bath, behind the bat panel, but I added a second even more accessible one next to the shower, one of those chrome

Do they also work to do the opposite: to keep air out? I have had times when I have drained the pipes whilst working on them but the shower instructions say the shower pump should not be used to prime the shower and that it can be damaged by pumping air.

Valves under the bath seem the easiest place but if you silicone the panel in place to keep the water out (essential if it's an mdf panel), it's not always quick and easy to get to the valves. I'm not sure where else you could put them if your pipes are not visible though.
