hi there thanks for the update. The one flaw in this beautiful bathroom? There's always one thing! Thank you for letting me know about this detail, because I was seriously thinking of doing it this way myself. In terms of your bathroom, I wonder if a very neat bead of silicone on the top only - of the join between the glass and the vanity - could help? This way the underneath is still fee to breathe and not gather gunk. But I guess then you don't get that lovely clean glass feeling from inside the shower.....

Hmm potentially although I suspect I couldn't reach to the back of it. Definitely not to do the alternating coloured panels I initially wanted but maybe with a roller on a pole....thanks for your suggestion, will look into it!

I would choose a light, warm colour for the walls. If you are uncertain what to use, you can pay for a colour consultant will go to your house to put forward their recommendations. According to their website, Dulux charges $150 for this service. I think it's worth that amount if undecided on colour. I love plantation shutters, however, with the extra large windows and doors in your house it would cost a lot to install them. Alternatively you could use layered curtains or insulated curtains. Use heavy fabrics or layered curtains over the windows to keep out drafts. Or, purchase insulated curtains with built-in thermal backing. Window pelmets are also good for keeping out the cold.

Do you have any photos, so that we can better understand what you want to do?
