I don't have a functioning camera right now to make an electronic photo file, but will remark that it is easiest inside a nice cabinet to use combinations of pex tubing and push to connect fittings such as Sharkbite brand (among many others) to avoid sweat soldering damage. All that is needed is a means to cut the pex to a clean flat end. Mistakes are easily remedied by using a different size piece of pex. Adapters exist to go from the pex to the fitting that dangling faucet hoses use. 3/8 poly line along with John Guest type push to connect fittings will be good for RO lines or such. Pex and poly are at their limit when used for pressurized water at boiling temperatures, so the hot water source in the house needs to be under some form of temperature control. A boiler type of water heater with potential for overshoot to 220 or so would be a risk in my view without a working moderator (required anyway by code). Some water chemistries tend to degrade the modulator so that needs to be kept in mind. My primary sink cabinet base includes garbage disposal and DWV plumbing, stand pipe for dishwasher hose, hot/cold feed for main faucet and to moderating valve for dishwasher (gets mix of hot and cold). Also there is the touch faucet control box, the fiber-optic garbage disposal control box, and quad electrical outlet. RO connection to both hot and cold sides of a pull-down faucet are present. All of the plumbing is mounted on stand-offs on the back or side walls of the cabinet base. kas

Your colors are lively. Bigger pieces have far more impact. One piece on each wall. Photos that are meaningful to you are often a lot more fun. For example, a bike photo from a city you have visited (or dreamed of someday) is more fun than a photo of a bike in some anonymous place.

IMO you buy art because you love it not because it “goes “ with the decor. I think one of the giant floral wallpapers would be great on that wall. BTW wood slat blinds and that chandelier do not work together

You have so many options! If money is no object, I think you should consider commissioning a piece from an artist you like. A personal favorite artist is Deborah Lynn Irmas (http://www.deborahlynnirmas.com) - innovative, graphic and also calming. If her work isn’t for you, this seems like a great excuse for some travel and art-hunting. Get something you like that reminds you of a place you love.
