If your kitchen is already delivered and in storage ( In your garage or at your joiners ? ) then you can unwrap some of the large cupboard doors, a couple of large side panels or your fridge freezer housing.
A drawer front is too small to get a good idea of how it will look. They are just in cardboard with a bit of sellotape, it’s easy to repackage. Just be careful you don’t chip the panels when you are manoeuvring them around the room.
If you have a 3m length of worktop, two of you can easily lift that.
Put the worktop flat on the floor / boxes / existing units and the panels vertically in front of it, just as you will have them in the room.
You are spending thousands on this so don’t be afraid to put it in the kitchen and have a good look at it.
It IS a wishy wishy muted shade, which is why I personally think it needs the contrast of very light or very dark colours in the other main surfaces - wall, worktop, flooring . And of course all kitchens need good lighting . But it can look absolutely stunning in the right room.
So can the grey oak worktop - I used it on the refurb of a kitchen earlier this year. The room had existing cream units and a brown tiled floor which were in very good condition, but the worktop, handles and tiles made the whole room look dated.
Worktop colour choices were very limited as the brown floor ruled out greys / black and the cream units meant white didn’t work. So we used that grey oak worktop and a tiled splash back in cashmere . The worktop and walls toned and the contrast was in the units and floor.
I think it looked lovely. But this is all just my opinion of course. Everyone has their own taste.
