Bathroom fan query

[tscott22]

Hi all, I have a few questions that I would be grateful if you could help me with in relation to bathroom fans. I want it to come on with the lights.

1. Can the fan go directly above my bath (which is also used for showering)?

2. Is there anything specific I need to look for in choosing a fan (I need it to be ceiling mounted), or will any fan do?

3. I intended to put the light switch outside the bathroom. Does the light switch need a DP isolator next to it?

Thanks

1 yes but preferably not

2 yes see //www.diynot.com/forums/viewtopic.php?t=126634

4 no but the fan needs an isolator, usually 3-pole as most have timers

5 this is notifiable work
