Definitely the white melamine rather then the wood grain............The bamboo floors will look much better next to the white cabinets.......

Is your kitchen a contemporary design......? What are your other choices rather then steel for the toe space / kickboard ?

Agreed. Don't do wood on wood unless they are similar. Real wood next to artificial is always a mistake.
I would also stay away from a stainless kicker, and opt for the white.
My personal suggestion is to select a laminate timber decor that is as similar to the floor as possible and use is in the kitchen but not the bare cupboard, for example, an open overhead shelf, or a feature panel on a return island back or island back. This way th timber unifies the flooring with it, making it feel more considered and homely, rather than plain stale white. Also introduce bamboo accents like a chopping board against your splash back and a nice bamboo fruit bowl. Consistency is key to making things interesting.

If you have time or are interested, I have provided some 3d images on a similar kitchen topic on this site, where you can see a kitchen with both these ideas being used.
It was regarding a small kitchen.

Thanks so much for your comments @ midesign0401 - where will I be able to view the images? Would love to have a look. Won't a white kicker get very dirty? I thought silver as the appliances will be stainless steel (sorry the kicker isn't stainless steel its just a silver look)

Hi Kim, the post was called 'ideas for a small kitchen' it's still on diseign dilemmas page three. Poster is hechlan.
Yes, a white kicker will get as dirty as a stainless steel one. Although maybe hidden a little better. M reason for mentioning this, as stainless kickers are an early 90's thing, and will prematurely date the kitchen. I have designed kitchens for around 10 years now, and while they have a place, as in you want to tie into your stainless appliances then go for it. I would just consider your options first.
The positive is that they will coordinate with an kitchen, however with a white kitchen, they may take some attention that the kitchen itself deserves.
Try to create something in your kitchen unique to your layout, and that is long lasting enough to enhance your own aesthetic.
Kitchens with personality usually have quirks from the owner, and this may well be one of them for you. My only reasoning is that I wouldn't want you to just do it as the cabinetmaker has been doing this for several years now. White get dirty, so does stainless, they both get mopped, and the stainless actually has a scribes surface which I know is harder to get the dirt out of. We used this in showrooms, and know from experience that flat standard laminate is far easier to clean that stainless kicker, regardless of the colour.
Ask your joiner for a piece of laminate and stainless kicker, feel them for yourself.
They often use HPL, high pressure laminate to make kickers, and not often LPM, low pressure melamine, as the HPL is far more durable. The joiner can explain th difference, or atleast know that you have looked into it.

Thanks so much midesign0401. Another quick question please (sorry). Matt white or gloss? The stone bench top is called clamshell (light grey)
