A couple of points to add with regard to the functionality side of things: Grey tiles, means grey grout which will be infinitely easier to maintain, every home that has cream or white floor tiles will ultimately end up with dirty grout lines, no matter how well you look after the floor. Grey tiles also hide dirt/hair etc better than light coloured tiles. From a design perspective, as long as you choose a tile that is quite simple and elegant, grey is almost always in style. Matching things to this colour palette is not so difficult, maybe stay away from microfiber chocolate couches though!

Cleaning the bathroom is a breeze, I have a nylon scrubber that I buy from Coles or Woolies and the cheapest shampoo I can find, after my shower I put a couple of squirts of the shampoo on the scrubber, run it from top to bottom all round my shower ( I have a large double head shower ) and over the floor then spray clean warm water from the top of the wall and let it run down the walls and glass area till the soap has gone, the shower in our 2nd bathroom doesn't have a spray so I use an empty Peters 2 litre icecream container keep filling it up with warm water and run this down the walls, hop out of the shower walk away and let it dry by itself -- once it is dry I have a perfectly streak free shower, for the bath and the vanity basins I use the same method, wipe them over with the scrubber and shampoo, flush with the warm water and leave, wipe the vanity tops, the area around the bath and window area with a damp cloth and hey presto a beautiful clean bathroom, this all takes only a few minutes and I always have a clean bathroom.

Thank you Monty. The tiles I have are actually across multiple areas aside from the kitchen, so am erring on not going with another set. Additionally the current tiles are the right style for the house and kitchen options I'm going with. A conundrum, but will continue scouring the options. Cheers

From what you have said, I think smaller separate pieces such as couch and chair(s) rather than a large sectional is likely to work better in the space and still allow for traffic flow. However, if you still have lots to do then don't rush to make large purchases. In the meantime, if your current sectional looks better pulled away from the wall a bit, then perhaps you could rotate the side table so that the long side runs parallel with the sofa arm instead of the wall. Would that help to stop it blocking the doorway and resolve the 'not quite right' placement?
