The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

You are so right white is never out of fashion. I would set your budget and then look at your options. If you plan to stay in the house for many years then spend to the top of your budget (if that is going to give you a life time of pleasure), if you plan on being at the home for only a short time / few years then I would go mid range so it looks lovely, will have good resale value but you can invest your well earned money to go towards something else as well. Obviously Marble / Granite is the top of the range but there are so many cheaper and very attractive options these days that look just as good.

What is the recommended measurement between wall mounted taps and our vanity top which has the basins undermounted??

Hi - about to renovate our bathroom and so far we are keen on using a combo of large marble/carrara floor tiles which will also go into shower area and up the walls of the walk in shower. We also want to use white subway tiles on another wall. For the vanity we are thinking of black wooden drawers with plain white stone top and white basin . For the tap ware we are keen on gunmetal but worried it might look dated in a few years. We want a contemporary look though. What are your thoughts on this combo. We thought of doing the vanity drawers in pale grey but think it might need the black to “lift” it as there is already too much grey/white in the tiles. Thoughts? Anyone got pictures of similar combos? Thanks!
