A soft mossy or grey green would be my first impulse but Sarah's dark blue looks good. It depends on your kitchen ware. White porcelains will pop with the blue and earthy stoneware will go more with the soft greens. I'd add a shelf to extend from the cabinet across the tile and a pot rack or hooks over the stove.

Hi. I think the overall look is good. Large tiles do make a room feel bigger as the pattern is less busy however I've seen the hex tiles in small bathrooms and they seem to work as your inspiration pic shows. I would probably lose the flowers though if I'm honest. Do you want the window for light or ventilation? Could a decent extractor be sufficient? I'm thinking that back ŵall could look quite busy. Is there any opportunity to change the layout? Moving soil pipes can be a little costly but could the sink be moved although ideally the loo would be hidden round the corner. You can pick up some great looking vintage or vintage style taps on ebay although unsure if the quality of the repro ones, If the layout can't be changed maybe have a corner loo and ŵall hung trough sink and put some storage in on the rhs as you come through the door depending on how you plan for the shower to open

It might be possible for you to make your bedroom taller by building into the roof void- measure how much space you have- you may be able to fit two floors in.

Your room looks large and lovely but with an entrance at one end and a fireplace at the other can seem a bit long. Firstly take EVERYTHING out. This will show the room in the best advantage and get rid of clutter. Only put back things you absolutely love. I would put two sofas or a sofa and two chairs (they don't have to be a suite) in front of the fireplace OR get a solid coloured L shaped sofa as it seems you are orienting the room toward the TV. You could then put a nice rug under a light-feeling coffee table (maybe glass and wood to pick up your chimney breast) in the middle. This would allow you to get rid of the multiple small side tables. I would lighten up the alcoves alongside the fireplace, either paint or light wallpaper. Get a proper piece of furniture for the TV to stand on. TV stands are ugly. There's lots to choose from. Try IKEA. Take down the heavy curtains and put in Roman blinds in a print fabric you love (try to find one with at least 3 colours) and coordinate with your rug. You could then use colours in this to make/pick throws and pillows. At the end near the door you could put in a small table and your rocking chair and make it like a separate area for music or reading with a nice standing lamp. Get some inexpensive drum light shades to update the lighting and put in another standing lamp by your sofa, as mentioned above, and lower your pictures to eye height. Good luck!
