Ok are we talking architectural designer or interior designer? Architects are more about lines and form and they grumble about the interior designers but that's who they hire to do the color boards. Either way you are the client and it's your house. It may be a great color scheme for the design but if you don't like it change it. Those sample of paint are worth every penny because you need to see more than a little chip. With your asymmetrical design you have room to vary more than the usual field or base color and a contrasting trim. I'd make a tracing of the design and copy a bunch of pages of it to use as a coloring book. (yes use crayolas:-) Another shade from the same shale grey paint chip and a one more accent color would be a good bet. If you are going subtle neutral, make it 3( not 50) shades of grey and play with where you put the darks and lights. Remember sunlight and shadows will create alot of contrast for even a "pale monochrome houses. (the computer rendering doesn't give you that.) You could add a pop a smoky teal, plum or coral if you want color as bold as you design. These would just be accents or trim. If shale grey it a really light silver you could make a monochromatic scheme with blue grays and a navy blue door and trim. The tan/beige in the rendering needs a darker grey to work. I would keep my midtone color on the lower level and a lighter shade on the second level. The top part that pop out could be a bolder accent color withe rest of the upper level almost white. Lot depends on your roof and window frames and whether you want them to blend in or pop out. Try a bunch out on paper or one of the computer programs before choosing any changes.

Just looking at them on their own (not in the context of the bath/basin) I really like the one with the black on it - 2nd... but I think you're right to try and match the bath and basin taps. That bath and matching basin are absolutely divine! Amazing shapes! And judging by the pic and your other queries, you also have a fabulous sense of styling and shouldn't need anyone else's opinions...? (imho)

We installed a Zip system during our kitchen renovation- the filtered boiling, chilled and soda. We LOVE it! Having the hot water at a moments notice is amazing. Not only do we find we're drinking more tea (great thing for health), but we use it to soak things, heat up cooking quicker, etc. I probably use it 10x a day! We start our day off with hot lemon water w/ apple cider vinegar- it's so nice to have it at our fingertips! I saw the comment about being too hot... the beauty is that you have the chilled water with the push of a button. So I know that I fill my Yeti just under 2/3 with the boiling water and then flip the function and top it off with chilled water. I can drink it instantly. The chilled filtered water is a bit noisy, but in a house with kids, dog, lots of activity... it doesn't bother us. I also saw the comment about filling Britas... with kids that play sports, filling up water bottles constantly is so much easier right from the tap. And they want cold water. They did need to reorganize the plans for the cabinet to make room for it under the sink, but it really wasn't a big deal. I also had to adjust the bubbles to get a higher volume b/c we like our soda water fizzy- it was not difficult. We were avid Soda Stream users... this is SO much easier. We used to plow through Co2 cartridges so fast with the Soda Stream. And then you have to send them back to recycle them. The tech for Zip said we'll probably have to change out the Co2 on this unit once a year. I would say that if you're going to use it- it's definitely worth the money, space and noise.

Go with your gut Tracy..... it is a big investment but I have found that if it makes you smile every time you walk into your kitchen you'll never regret it!!!! I've recently moved into a smaller downsized home with my 3rd black kitchen, with drawers, no cupboards, except for the pantry which we use as the crockery and wine glasses stash. Mine is matt but no handles = no hip bangers! I chose to use snow white stone bench tops, the walls are painted natural white while the floors are pale oak hybrid vinyl.
