Hi there. If the tile you have has character, you could pull a colour from some of that character, for example if the tile had a beige fleck through out you could use a similar beige tile in the bedroom, otherwise just choose something that compliments the tile well to create a soft transition. Then use the colour of the existing tile in the room somewhere, with your bed linen for example or bedside lamp. Feel free to share an image of the existing tile.

Hi there, this is very touch. But you have discovered the base principle already, soft materials or materials with a lot of surface area absorb the sound. Just shooting out some quick ideas here for you: A soft and thick rag or bath Matt on the floor. Curtains are a good sound absorber, but not to much in a moist bathroom. Potential mold issue ;-) Another idea could be to hang bathrobes on hooks or a fabric laundry hamper onto the back of your door. If you find its still not enough.... since your walls are already tiled. you could do something on your ceiling... like a timber slat ceiling or a painted plywood paneling with holes in it. Make sure you use polycaprithane paint for moisture protection on the timber.... hope this helps. If there are questions or you need more help, feel free to send me a message. Cheers Gunnar

Used beveled subway tiles for whole bathroom without thinking about internal corners so the corner looked terrible then the silicon went on and it still looks terrible I guess apart from an aluminium strip or a marker to go across the silicon there aren’t many options

Eh ? You want white or off-white or similar ? Your kitchen is white and off-white , with quite a light wood . And a nice red toaster . I have noticed the toaster , and commented on it . You have purchased the toaster . Other people will notice the toaster , and comment on it . Because it is the only mildly interesting thing in the kitchen . Dark grey doesn't sound interesting , but charcoal does , so I am hoping it is closer to charcoal than dark grey . Am I overly optimistic ? Can you swap the dark grey for black gloss , because I suspect black gloss subways would look quite good there , and tie in the oven and cooktop too . Now what would happen if you were stuck with the grey or charcoal , and went out and bought a dozen crisp white subways , and a dozen Red subways . Get your 30 or so charcoal subways , and lay them out in a rectangle on the floor . Take 6 out in a reasonably random way , and put white ones there . Then take out another 6 , and put red ones there . Depending on the grey/charcoal , it may look crap , or it may look okay . If it looks okay , put the dozen grey ones on the top , take a few more away , add more red and white . Overdone ? Underdone ? Have a play . Don't like it ? Get all the grey ones , and 'stand them up' ( lay them vertically ) . Lay a line of red ones horizontally across the top , another line of white ones horizontally across middle . Swap them . Don't like any of them ? Get some brownish Tavertine Tiles , or an Orange ( or red or yellow or citrus green or your favourite colour ) glass splashback . Experiment . Put the on the bench and imagine . Thats what I'd do anyway . But I wouldn't do only dark grey , and I probably wouldn't do charcoal on its own , but I'd see first .
