Hi ysteb1 I found a tile that looks like a light beach style hardwood from National Tiles. They are long (1200mm) and narrow but I think the look will be nice. They are suitable for a bathroom so going to try them out.

For those still reading this thread. We just recently completed a bathroom reno in almost identical sized space though turned the other way. A lot of reflection in the photos sorry but there is a lot of glass and mirror. A cavity slider, while an added big expense, made the whole thing possible. To create the space I used the adjoining separate toilet room for the 1200 x 900 shower and shallow tall cabinet on the left and gained a closet in the hall outside with the rest of that corner. I also recessed the towel rail which helped give room to the shower entrance and not stick out in front of the loo. Wall hung vanity and toilet. Porcelain wood planks on floor with underfloor heating and also used in shower base. Excuse the towels, they are not my normal ones ! It was a big decision about joining the rooms and whether to keep the bath / shower but I think it paid off. There is just the two of us and it's a real pleasure to use and no longer feels like "standing room only"

I have a power point on the wall above the vanity and between it and the bath but I don't plan to have anything plugged in permanently or ready to use even though I could, as I have a hob at the end of the bath which is over 700mm wide so the bath water is quite a distance from the powerpoint. There appeared to be no issues with putting it where I did but to my knowledge plenty of bathrooms have a powerpoint beside the vanity but based on your layout, I would at least put it on the shower side assuming you have a screen there.

don't think it would matter, if you wanted to match a mirror to anything at it would be the vanity and that doesn't have to be. either. Perhaps some photos and bathroom layout might help give you some suggestions. Also use the new Houzz Ap, go to the your Houzz top right of page and click on "create new Sketch"
