Painted cabinet doors are generally at the top of the price point, with polyurethane in either gloss, satin or Matt finishes being rather expensive, and hand painted doors even more so. Laminate on the other end of the scale are cheaper, but also only have the option of a flat door. If a profile is what you what, as most if not all painted doors are profiled, ( have a door shape), but the durability of laminate is wanted, then a vinyl door can provide both. Depending on your door provider, try to stick with Australian manufactured vinyl doors to ensure they meet our regulations, such as albedor or tesrol doors, and they will give you best of both worlds. Also, being that they are cheaper than painted timber doors, modern kitchen construction means replacing doors are as easy as clipping off hinges, and ordering new ones!

What look are you hoping to achieve? When you say 'update' can you elaborate?This kitchen looks new. Compared to my old Barbie pink, laminate, falling apart beast, this is a dream! I personally would never paint a kitchen myself- especially not one like this. Lots of sharp edges means lots of future chips/scratches. If it is 2-pack poly you could get it resprayed. I can see scope to change the cabinet pulls, add a plant or 2 to the shelves, bigreaders suggestions about moulding are awesome. Even if you got a cabinet maker to pull out the open-shelves and replace them with a timber or timber-laminate as a contrast. All this would soften it and add personality. I can see your roller blind on the window- changing that to a roman blind with a pattern/texture/colour through it would add character too.

Sorry, I can't edit posts from my ancient iPad. You might see if you can find a sample of the other materials you are considering and give them the "touch test." Good luck!

Your floor and other wall colours are great but Red (orange), black and white are very harsh together, the wall cabinets either side of the range hood have been badly installed, they should have been built to the ceiling. My suggestion is because the kitchen is small, I would remove the cabinets either side of the range hood and then run a row of white cabinets across above the sink to the end of the bench top. Paint the walls white or a soft grey, the range then becomes a stand alone feature. You didn't mention what the splash back material is but I would consider a clear mirror splash back along behind the sink and up to the base of the new white cabinets so that you're not just looking at a wall. cheers
