Hi. It's hard to tell colours online but your tiles seem to have a green undertone, wonder if farrow and ball mouses back (1st pic) would work? I'd add a wooden bath mat, this one is available from Victorian plumbing. On the wall opposite the sink a towel holder with a hammam towel, this is from not on the high street and available in a few colours. Do you also have room for art on that wall? I'd add a potted plant at the end of the bath. If you have the space then 3 small dark wood shelves over the wc and mirror over the sink and add candles etc.

Very nice! The tiles are lovely in the last image.

Thanks, good luck with it! We felt that it used the space a bit more rather than just having the furniture arranged along the walls. I like the look of the free-standing bath in the corner (something i had seen on houzz!) and it seemed logical to us with the lay out of our bathroom as to have it fully away from a wall would take up valuable space so the corner seemed the perfect compromise... behind the bath provides handy hide-away storage ;)

Good for you! When you source your next contractor don’t be afraid to tell them exactly what you want - all the little details. Inspect work at the end of the day, ask questions and make sure things are on track. It feels scary, but you are paying them for their time and at the end of the day you‘re essentially the project manager as well as the client and need to be happy with the finished product. In my (limited) experience, once a builder knows how precious you are about finer details, they’ll consult you on certain aesthetic decisions.
