Lovely area! You have done a great job! Just a thought i would have put decking to one side and only had one side with stone and plants as putting the decking in the middle looks like a runway. Just my opinion. Black stone would look great instead of white. And painting the back bricks would have been better with a darker colour to make timber "pop" like the colour of your fence or black like the posts. Loving your ideas and transformation is fantastic!

You never mentioned your budget that you're willing to spend. You could add a thicker fill backed insulation blanket - 50mm, 75mm or 100mm are the common thicknesses. Steep roof pitch so would need scaffolding, harnesses, etc.. which adds up quickly. Probably still not enough insulation though but probably cheapest option. Insulation under existing timber linings then reline over the top of that as some have suggested. Working at height though so would need scaffold set up again and working overhead is not fun nor easy. You could replace the roof with a sandwich panel roof. Try Versiclad or Kingspan or comparable. They have a polystyrene type of insulation between an outer metal roof sheet and a metal inner sheet. These are heat laminated together. Again different thickness available from 50mm up to 180mm is common. The 180mm has a R rating of 4.7 which is quite good. Again steep pitch, etc., probably need new ridge capping, etc.. Probably most expensive option...... Keep us all posted on your decision though!

We had a guy who printed posters print the photo and stick it on the glass for us (to make sure there were no air bubbles). He delivered it to the glazier who was installing the splashback. There was so much interest as it sat in the showroom, the glazier then started offering glass with pictures actually printed onto them... If your wall was smooth, you could put the 'poster' print onto ther wall as another option.

Hi dreamer, thanks for the suggestion. Im wondering though, how do I treat the junction between the vanity and the fixed panel of the shower screen? The diagram I uploaded above leaves out the shower head, so there will in fact be a shower-over-bath in the above scenario, with a fixed panel adjacent the bath. If I have the vanity hard up against the bath, I'll need to tile the side of the vanity, no?
