So many opposing, I actually love it! Just re designed our ensuite and as you walk into the bedroom you can see our beautiful bath under a leafy window! And shower is in full view- we don't have issues with nudity. The toilet is more hidden behind a book though, There is lots of airflow and no dampness. I do have an extraction ceiling fan, Obviously you can still get privacy, and we have another bathroom to use for the smelly stuff (lol) or if one is waking earlier than the other to get ready for work :)

I think you can very well still have plants in a windowless room- as long as you're willing to give them regular little 'windowsill holidays' in another room. I'd go with succulents, there are some great warm colour combos (see Pinterest for ideas) and the geometric shapes mimic your tiles. Of course, there are some incredible fake ones around too, saw one last week I could not pick from the real thing. I'd be tempted to mix in some of both to balance aesthetics with practicality! Separately, I'd be careful of adding any soft furnishings (rugs, spare towels, etc) to a small powder room. We are all aware these days that a flushed loo spreads germs a meter around it- I wouldn't want to be collecting and trapping them! I think (subtle) fragrance and votives would warm this lovely space without impeding hygiene.

The timber railings on the verandah we are replacing didnt stand the tests of time, so I was hoping for aluminium or as mentioned PVC. However this seems really hard to find, unless I settle for a contemporary chrome type number. Can anyone suggest a supplier of PVC or aluminium railings please?

you used to be able to buy Minwax at Masters when they were around I would try Mitre 10 I used it on another property and it was excellent
