After a lot of fiddling around I managed to change the ensuite taps without them leaking. The original supplied hoses leaked badly (Chinese made...say no more) so off to Bunnings and $14 later no more leaking and swear words...lol.
The pop-up wastes proved much easier...Metricon wanted $50 each which to be fair isn't too bad but I was able to do them for $17 each...so a bit more money to spend on something else now.
Noticed an interesting reflection of the flash bouncing off the splash back tiles onto the taps.
