I love it, and are considering this myself which is why I can offer an insight to installation. Yours is luckily freestanding, however I would install this central to the long part of your L and enclose it within cabinetry, actually yours is Likely to just be faced with fake doors and no carcass behind, still a place to utilize storing buckets or baskets, even laundry powder, just not a standard cupboard. I would then actually install a stone benchtop making this technically undermount trough. You would still have the practical size and aesthetic impact this concrete relic has to contribute. Only, with the bench top area to make it a useable space.

So the primary focus of a splashback really should be function for sure – it needs to be a smooth surface that can be wiped clean quickly, effectively and bw waterproof. But that’s not to say the splashback shouldn’t look terrific in the process, either. These days they are anything from tiles, glass, acrylic, pressed metal.. even art! :) I'm gauging from the responses so far mirrors 'do' tend to go 'hand in hand' with hand washing. On this particular project it wasn't a necessity and offered an opportunity to try something away from conventional design so to speak and allow for a corner art splashback to take pride of place in an unexpected place. I'm enjoying the comments and the thoughts Houzzers are sharing on this poll. Civic Steel I've been informed more selfies have been taken in that small bathroom than any other place in the home recently which was amusing to find out :) and Jmm1837 I've completed many feature walls and art installations, I may possibly have to consider working 'around' a mirror on future backsplash projects. Thanks also for the compliments re the work. :)

After much consideration of your photo, I really think you have it right! The gold mirror matches the gold towel rail ! All your other elements, i.e. the plant and stand, match perfectly with and enhance the room's overall look. I think the suggestion of painting the wall behind the mirror, is an excellent one, in a shade of green which would tie in with the tiles on the floor and the plant. You have the ceiling height to handle it. I wouldn't be shy with a dark emerald green to complement the tiles, I think the gold would then really shine and blend with the gold hand rail. Photocopy the pic of the room and using a texta, colour in the wall and see what you think before committing. Be brave. Congrats on a beautiful room! Good luck.... i do hope you'll show us the end result whatever you choose to do.

looks wrong as it is currently - IMO it would look way better centred in height between ceiling and vanity and also possibly better centred to the basin, since it's offset to the vanity - a mirror centred to the vanity but offset to the basin could look odd - but it's hard to judge accurately from those photos as it's hard to gauge the scale of all the various elements.............like with everything to do with design it's always about balance
