Hi Lorraine,

This particular fan has a 25 watt motor with a 134mm fan. It clears 320 cubic metres of air per hour (m3/h). Now, how you work out if that is powerful enough for your room depends on the room size and what elements you have in the room.

For a bathroom with a shower you'll need more air changes than one just with a toilet - so the basic formula is to work out your room size (length x width x height), then multiply that number by how many air changes you need per hour. In general, we say 10 changes for a toilet room, and up to 25 changes for a shower room, depending again on how steamy your showers usually get.

Once you have the room size, and the number of air changes you'll likely need, you compare that to the m3/h rating of the fan.

There's some more general info about choosing an exhaust fan in our blog if you want to have read - http://www.cetnaj.com.au/blog/how-to-choose-a-bathroom-exhaust-fan/

Hopefully that makes sense and has helped - let me know if there's anything else you need.

Thanks for your comments, its great to discuss with houzers! You are so right @decoenthusiaste the view is beautiful and one reason why I chose the apartment. the room is longer than it is wide, and I wanted the kitchen/bar to be included in the seating so the attached pic is how I was planning to lay it out. @cdrdesign I can't/change the table, its a gorgeous mahogany piece I had custom made and one I see keeping for some years yet! I dont plan a TV in this room, will put it in another room. This room in for living and entertaining guests. Sorry I dont have layout software, so you will have to make do with my scribbles using powerpoint! Could really do with help on choosing the light fitting in place of the central fan- what would look nice here or should I wait till the furniture gets here to choose the light to match?

I take it this isn't your bathroom. The glass could be handmade lead light which means bespoke by someone who makes lead light windows or it could be a transfer applied to a plain glass window. Check on ebay or online sticker/transfer stores for similar. I've never seen a piece like that in Australia so I'm thinking this might be an American antique. It's not normal to put an expensive antique piece in a bathroom and if you did it would be best in a bathroom that only has minimal use. And you would want to have a lot of good exhaust extraction to get rid of moisture. If you picked up one of those repro Indonesian mahogany pieces you would be spending a lot less money and might regard the piece as expendable. You can buy wood hardening sprays that resist moisture from the hardware store and spray the carcass (all the unstained pieces inside) with this stuff to resist moisture. You'd still need a good exhaust system however and keep the room well aired.

Hi 4eva zx, It's not optimum if you don't want to build a bespoke TV wall/console where I've placed the TV here (suggest that you get something where you can swivel the TV towards the sofa, or slightly extend that wall so the TV can be directly in front of the sofa), but in terms of spatial efficiency, your round table would be better placed like so: This is so that it's near the kitchen and you can use it for meals for more than two people. This placement will also allow you to make this family heirloom a visual focal point and conversation piece for your home. If you ever need to use a bigger table for gatherings with more people, you can simply put a rectangular top onto the round table and seat 6-8 people – the placement provides for space that allows this. Find a good ID or decorator who will work towards incorporating this family heirloom in your new home, and you'll be able to enjoy it for years to come. Hope this helps!
