Hi there, We have an assortment of floor tiles that you could choose from! I'd recommend any colour that's darker than the wall tiles, as it should mean you won't find yourself constantly worrying about cleaning up after yourself.

Jonathandb1972, I was thinking of going with a grout that is the same colour or lighter than the grey tile. The hex will be grouted in a medium grey. This has already been done in the loo (the hex) and looks great. Neither are grouted in the above picture. Do you think there will still be issues with where the grout lines are if they are the same or lighter than the tile? Also, where the hex tile in the shower meets the grey tile will mainly be covered by the shower's profile. However, the shower only goes up to about 2m, so there will still be a visible "meeting" of tiles above that. My builder is a little concerned about how this will look as he will have to cut small pieces of tile to fill up the edge, which may stain once they start grouting. I'm keeping my fingers crossed and hoping for the best...

A picture would really help! A large landscape mirror is a good bet in narrow hallways, as long as the frame is not obstructive. A dado rail will help break up the height (so giving the illusion of more width), and allows her to paint a bolder colour below the dado without making the space too dark (white or off white above the dado). Maybe even a picture rail too. She could use satin eggshell under the dado, it’s tougher and more easily cleaned than emulsion, and also has a sheen to reflect light. A large coir mat near the front door, spanning the full width of the hall, to help keep things clean and also reduce the visual length of the hall (to help it look wider)
