Are there other design elements that you could incorporate? We have a similar mountain industrial rustic thing going on, with knotty alder trim just like your mockup. However, we also have a lot of black square iron elements throughout. So we did mirrors with the metal element and carried that through the bath hardware.

@LH CO/Fl...good idea. Only design element is the trim detail with blunt cut edge and slight overhand (like in mirror mockup). The house is kind of minimal I guess, see great room pic from this a.m. (furniture on order). The furniture is pretty contemporary but not ornate - more moutain modern I guess.

I personally would probably not do the wood mirror, simply in order to avoid overdoing the wood/cabiny effect. I think I would choose a black framed round mirror over each sink, which I know is not one of the options you gave, but just what I would do in your shoes.
Best of luck!

I would definitely not do the knotty alder, but would probably look for something a bit more special than the plain chrome frame for a master bathroom.

This is what we did

I personally like the simply mirror frame so that they windows with the fantastic views are the focus of your bathroom.

@emily Simple and sleek sounds good. I wonder if there are frameless mirrors with contemporary attachments (wall holders)?

Are you looking for something like this:

The mock up mirror is too visually heavy for the design of the room. I'd go with a frameless, or a very thin fram using the wood.

Could you create them from clear alder? Knotty alder is busier.
