First of all, you should change the door swing from Left hand to Right hand, so you walk into a room not the wall. Put the bed where the dresser is now and the dresser on the other wall. Other then that there is not much room to do anything, or replace the window, insulate a wall and leave everything as is. Good luck

Kind of funny really how many people would feel exposed and would not want to use the bathroom. The more I think about it, it's a bit like a public restroom with stalls (as stall walls rarely go to the ceiling or floor and have the added issues of gaps between the wall panels and doors -- which thankfully we won't have!). Regarding the humidity control issue, I should have clarified this is only for a toilet and small hand basin (not a full bathroom with shower). The main room on the other side of the proposed toilet is our dog whelping room where we will have young litters of puppies (when we have them). Further down the hall, removed from this room, is our training room where there are likely to be other visitors but the proposed bathroom would be quite removed from that area. It would be wonderful to find more windows like the ones that are up near the ceiling! That would certainly solve the issue. I'll have to scour the demolition/restoration places.

Have you tried hitting up the place where you bought it from or had a look at the manufacturer's website?

I didn't like any of the stock standard vanities I saw being sold. By chance I happened to see a second hand vanity being sold on FB so I brought it ( see photo). I liked its shape and solid profile but didn't like its colour. I took it to a auto car spray painter and had them spray paint it in Benjamin Moore Kendall Charcoal (a greige grey). They did an awesome paint job with a mirror like finish. I brought a piece of primestone (marble look) for the top, two small towel rails to be fixed in the underside of the vanity that is sticking out so I can hang hand towels on either side. I brought a new tap for it (but kept the vessel basin). I ordered in some new legs for it online because I didn't like the legs on it (see below). Its currently at a joiners getting put together. I've actually enjoyed the process of pulling it all together. Sure by the time it has been put together I probably would have spent the same amount that it would have cost me to do a custom vanity however I think there is something to be said for re-using something a second time round rather than buying into consumerism that abounds us. All up I've spent $1,074 NZD for the vanity, the spray paint job, new legs from www.prettypegs.com, the new towel rails from Reece Plumbing & buying a new Elementi tap. That doesn't include the joiners costs - yet. I needed storage in my vanity. This one fit the bill for me. Good luck with what you choose to do! I am doing a bathroom remodel as well and enjoying it.
