I would suggest your plumber links the hot and cold fill pipes to the supply UNDER the sink - this gets rid of unsightly pipes and while he's there get him to move the taps to the L side of sink. I would then create a broad drop down counter top to create a place to sort your laundry ready for hanging out to dry or to fold ready for ironing This drop down counter top to be hinged to R side of washing machine and ensuring the taps are not impeded. If you can't do the drop down version then create a free standing top made out of a piece of MDF/laminated board to put over the sink and washing machine for clothes sorting & folding. This free standing top can 'live' at the side of the washing machine when not needed. I would then put shelves above the folded back counter top to store washing powder and sundries. I would store the washing powder etc in colourful or white boxes to keep the place looking tidy and uniform. Handles on the boxes for ease of access. Oh I do love organising - can I pop round and do this for you? Hope all goes well with the changes.

I would look at this room from 2 angles, in this order: convenience (as you have young kids and need everyone to be able to fully use it) and aesthetics. Equipment and accessories: #1 - first look at what is necessary to have in this bathroom: a place where to keep soap, toothbrushes, toothpaste -- all within easy reach for all users (including not-tall-enough kids) #2 - a cosmetic mirror ? #3 - a towel rail #4 - a small cabinet for storage Ideally, #1 should be stored directly on the sink, as it's lower, within easy reach for the kids (see below photo from one of our baths): You can do this also witha smaller sink, like the one we use in the half-bath: If you'd like to keep the one you have (which is really nice), you'll have then to use a shelf (as also suggested by someone else above), and I'd propose one of white porcelain and not one of glass, as it's a lot less reliable with children around. Below, an example of what I mean. The shelf should be installed as low as possible to be reachable by the kids, but also the mirror should be much lower, so that they can use it (much more interesting for them) without having it too low so the adults can't see themselves anymore. For #2 look on the left of the mirror in this photo (if you need it): A towel rail (#3) is absolutely necessary and make sure it's one where you can stretch the towel for faster drying (like the one in the 2nd photo). The cabinet storage (#4) could be placed on the wall from the right of the mirror, as you can see we have in our half-bath (also 2nd photo): Aesthetics: I agree that blinds on the window make no sense, light should be let to flow in as it's much needed in a bathroom. If you don't have time or disposition to paint the walls (and maybe they should remain white anyway, or a light color, because this is a small space), you might use decorations from your DYI center and stick them on the walls (see an example below from my daughter's bedroom, but there are other smaller ones for any kind of space): This way, the room becomes more attractive, more welcoming and more colorful (with very low cost). I hope this helps :-)

We have that exact sink! And a very small powder room stuck in the 80s. Only difference is our door is on a side wall, and there is no window. We're no where near finished, but just ripping down the pink floral and stripey wall paper has made a huge difference (including revealing the toilet is in fact white, not pale pink). We're going to replace the rather unappealing plastic sink with a tiny ceramic one with new taps, and the old plastic cistern with a new colonial style ceramic one, and new seat (keeping the toilet base as it is in good condition, and classic style). Then new paint, and a good clean and regrout to the floor, new light shade, toilet roll holder, storage in one corner and art.

windows in master bedroom need to allow views and privacy and much as i would prefer bed on NE this keeps the bed in view towards and from family room so prefer bed on south wests wall and small sliding doors pushed towards north side of room with tall narrow window beside sliding door and highlight window for light with privacy and wall space for chest of drawers...acknowledging theta the pwdr doesn't have a window but my suggested arrangement uses less total space more efficiently and is better for older kids and long stay visiting parents (more people can use the various options at the same time) and a small ventilating skylight will exhaust and brighten the toilet and vanity area ...the wide door into the lounge can be a stacker or stable door so you need to investigate local options (and everything is expensive unless it does what you want...we always use solid core doors that can be ten times the price of a basic hollow core door but love them so we economise elsewhere) and barn door between entry and family would be OK as long as you like them and it doesn't compromise lounge doors but could look ok if both doors are the same style and different widths...and location of dishwasher is personal and if you have already been unhappy with sink in main kitchen then have it in the scullery...main advantage of my suggested kitchen location is that it's closer to the front and the family area and external doors and the pantry uses the central space that can be much better illuminated with another ventilating skylight instead of a tiny external window and noisy exhaust fan
