Old post but thought I'd update. We have finally moved into our forever home and on occasions, obviously in winter, we still have crying window (sob). We have the wet windows on the south side of the home which is the shady side so not unexpected but also on the north side where we still get lovely warm winter sunlight streaming in and I still do have all my windows slightly cracked open and it does help. Incidentally I have glass bricks in our bathroom on the south side and there is no condensation on this window at all. Our home has insulation in both the exterior and interior walls and we have double insulation in our roof, so factor 7 unlike the usual factor 3.5 not that it probably has any bearing on the moisture issue. We have a 1.8mtr wide veranda surrounding the entire home so the windows are some what protected from the elements but when the temperature gets fairly low and can be almost zero in winter, it seems impossible to prevent this crying window sindrome but I can live with the fact it is fairly easy and quick to remove with a Karcher window vac now, brilliant little machine at $99 and it only takes a few minutes. We have an exhaust fan in both bathrooms that is vented outside so the moist air does not go into the roof space and in fact even my rangehood ducting is vented outside too!! We even had condensation in the roof cavity as well to the point of having a rainforest up there but since fitting another whirlie into the roof making it three in total now, it appears to have almost entirely eradicated that problem. I can say catagorically now that crying windows are a very difficult problem to eradicate in very cold climates where obviously the inside of the home being heated at night is going to create the perfect conditions for the condensation to settle with the inside being far wamer than the outside and there in lies the problem which canot be changed. I have blinds and curtains that I close ever day before dark but it makes no difference. As I have aluminium windows and doors throughout, so no timber anywhere, it isn't such an issue for damage but annoying none the less but life goes on and I do so love my beautiful new home!!

@ Luke Buckle yep that’s the one. Has 1000w/200w switchable. I just put an oil heater in there 2 days ago to trial and room was toasty in under 5mibs WITH A non instant oil heater so a fan type wouldn’t take long. Also consider the heat lamps are 250w so 1000w total if all 4 are on. They feel like they are frying your head off from above when blazing all 4 lamps so depends on what “feel” you want also. As someone mentioned, let alone the cost of lamp replacement. Having been in lighting industry they wouldn’t last super long either (perhaps newer ultra violet do but their also pricier again)... I’m no better either!

I do bathrooms every day of the week and I can tell you now that, If you really want a bath in that space and shower just do a shower over bath I noticed your shower was 800mm wide this is to small for a shower 900mm minimum. Forget the bifold doors put in a cavity slider or if this is not possible do a face of wall sliding door on the out side of the bathroom. If you really really want separate bath & shower move the toilet into the laundry. Get an 1800mm deep soaker bath and run it along the 2000mm wall run your shower along the 2100mm wall opposite the vanity. I take it your on a timber floor not a slab as moving a toilet on a slab can get costly.

A summer must have for me is a big glass jug — whether it's used to hold infused water or a fruity cocktail to share, it's something I'll definitely be buying to ensure I stay hydrated.
