I'm looking to source replacement doors for my existing standard height underbench units and wall units. Does anyone have any recommendations ? Ideally looking for something other that flat profile.

My comment would be that fluted glass would be a bit harder to keep clean??

I'm looking for a door lock suitable for a cavity slider that can be locked/unlocked from either side regardless of what the other side is. Sounds confusing???? Let me try and explain, and please see attached photo... we have a cavity slider between our main bathroom and our guest room (Bedroom 4), like a Jack n Jill bathroom or a Poor Man's Ensuite as they're sometimes known by, and I need a lock for it so that if there are guests they can have the door locked from their side but if someone else uses the bathroom it can also locked from that side.

That looks like a NZ house . and possibly even an ex-State House . They were solidly built ( money wasn't a problem ) . But it would need a builder and some investigation , because there will be studs and power and it may even be load bearing . Back in that era , most water and piping was pretty much straight out and down , but there may be piping for water or sinks or showers or similar . You could buy a $100 door at the demo yeard , or a $2500 masterpiece . Tiy might want a small deck and some stairs , you might want a small roof , you might want something more solid . Then you'll need a door jamb , some framing , then presomably paint and maybe wallpaper , Possibly lino or tiles or carpet . And can you match everything , including the paint tones etc , or will you have to redo a whole wall or even the whole room ? Then theres permits and fees and inspections . I'd suggest you won't get much change out of $10k if basic , maybe $25k if you want to go a bit luxe and/or strike problems . But then again , I'm not a builder -- give one a call .
