Thanks Guys for the feedback
There is more fall on the pipe from the sink waste that than can been seen in the picture so i think this will be ok, No problems so far 12 months
The bath panel is removable and is only secured by a bead of silicone and magnets on the back so i can remove it if needed
I have added a pic of the tiles and the ceiling how its finished.
Also a pic of the toilet as requested, Roding point inside the cupboard for building inspector
This complete panel behind the toilet is also removable you can see the clearance gaps. I have sealed these gaps post this picture with white silicone to neaten the finish it and it now visually looks like the bath panel
I am not a tiler and i know my job is just average but it looks ok and is functional
It is just the spare bathroom in the annex
Also in reply to the question about access to pipe work in kitchenette, yes i have full access to get to all my pinwork in case anything needs changing
This looks a lot different from when i started the extension.
