Don't Apollo Blinds do every kind? Cleaning blinds is a horrible task. They sell some crazy looking brushes for that task but i have not tried one.

External doors should be solid not hollow core. Beyond that it is as Tribbletrouble44152k7 Trek said, depends on budget and other priorities, and I'll add the house because the nicest most expensive door will look wrong if it looks out of place with the style/colours of the house. From everything I have been told a timber finish needs redoing more often than a painted finish. Edited to add, I thought to check what exactly the standard Hume XS45 1200 door is and for clarification the question is about the same style but the choice between the standard maple finish and the merbau finish? I therefore assume you intend to use a timber finish and amend my reply to ask whether the merbau is a better match for the other colours in your facade?

Unfortunately the door had to swing from that side due to light switches having to be a certain distance from water (shower). Plus I’d rather have the first view be of vanity and bath, rather than shower and toilet... Solution was to go for a hidden control arm (Glynn Johnson 410 series concealed overhead door stop) at the top of the door that bounces door back away from shower screen. Can’t see it when the door is shut. Plus didn’t interfere with water proofing/tiling.
