@LazyVirus - Everything you mentioned to me, i mentioned to the layout designer. I was told to not worry about any of this and to proceed, the main purpose was to show the layout he had in mind to a customer.
There is no mirror because the client said he had not chose a specific model yet, so i was told to ignore that, same for other “Un Necessary objects” such as the toilet roll holder and floor rug etc.
And the tiles were added in the last 20 minutes before i hit my deadline and had to get some renders out for the next day before i ran out of time.
They are just a placeholder really, as the actual tiles he wants havn’t been decided on yet.
I appreciate the in depth feedback mate :), and if it was up to me, all of the mentioned aspects would not be missing/un-realistic. I just ran out of time and had to rush.
But the person i did this for was more than happy with it. Who knows, maybe the customer will bring up some of the issues you raised, and i will be back at work on this scene again 
@jorgedct2 - Thanks mate
I rendered these out at larger resolutions for print, these images have been scaled down
the originals were average 2.5k resolution at about 750 - 1000 samples on a GTX660 2GB (Using 1.65GB to render the scene)
and most of that memory was taken up with large textures (3 - 4k)
