Best of luck. Attaching photos like you did greatly improve your chances IMO.

@Dytecture: you might want to read the rules for the contest.

Thanks for all the great advice and information. Attached is a possible floor plan...it shows outside measurements of the existing space. And also a photo of the stream which I initially mentioned that runs beside the home.

So you want a powder room in there and a laundry space? A shower too?
And the door at the top of the drawing is the one you'd like to have to go outside?
Plus, the adjecent hallway with the old heater is in the right bottom corner outside the floorplan?
Could this space be added to the laundry and bathroom? Would you be ok if the laundry and bathroom were joined together in a nice finished way?

Note: could you please post the measurements you've written down, they became too little too read. Thank you.

The overall measurements are 9 ft x 12 ft 2 inches...with a box in the upper right corner 30 inches x 33.5 inches which cuts into the room due to a chimney.

I would love a shower. And since I live on a lake I am actually considering an indoor/outdoor type of shower arrangement so that people can shower when they come in from swimming. Especially since this side of the house is fairly private along the creek...it also has an additional natural water supply...any artesian spring which may be incorporated for a water effect in the design. But due to the harsh winter temperatures I don't know if introducing such design features would actually be possible??

Here's a layout for you. I hope you will get the oppurtunity to build your dream bathroom.

You see I've taken out the wall, because the sense of space is more important than seeing the washer and dryer. You could have a cabinet built around it (or a simple curtain in front), I only drew a full height panel on the side to finish it off and maybe hang a towel rack (for example) on the window side.

Toilet and sink speak for themselves, the cabinet next to the sink could be extra counterspace or a full height closet, depending on your needs. Under the window is room for a hamper, bench or clothes rack (in front of the heater?). I kept the toilet in that corner, because the main pipe will probably be somewhere over there.

The bathroom has a tiled floor slightly sloping towards the shower drain, so the shower has an open feel and is easy to clean. A normal slider door can be closed to prevent splashing sideways.

You'd like to have an outdoor shower, but because of the risk of frost damage I kept the shower indoors. Large (aluminum) sliding doors with (partially etched) glass make the outdoor connection.

Tell me what you think. :)

Thank you very much for your good work. I realize how hard it is to understand the space when you are not here. Since I have a very large home and laundry is quite a production when many guests are staying in the home I did not want the guests to have to walk through the laundry room in order to use the bathroom. This is the reason the initial design sketch calls for the two entrances. Plus I do need storage space for my linens to be hung in preparation for beds to be changed to avoid the need for re-ironing. With all these laundry needs....this is why I thought the only way to also incorporate a shower would be to go out on the same wall that has the window...plus as mentioned it would be great if people could shower off after swimming in the lake and utilize the bathroom as a space to change. But at last, I know it is asking a lot from such a little space.

What will happen to the space where the old heater is, plus the hallway, could it be incorporated to the laudry or bathroom? If so, could you please add that to the drawing? I understand the nook next to the door is a chimney, yes? Adjecent rooms that can be of any help?

Still quite possible. Moved the inbetween door more towards the middle, filled up the old doorway with milky glass blocks, so it lets some light through. Made the toilet 'area' a little wider, so the corner sink (little vessel on top of a tiny corner cabinet) wouldn't look/be too cramped. A wall-hung toilet would look nice. From inside the house you'd still need to go through the laundry to get to the bathroom, but you could lock that, so it can only be used from the outside by guests. Machines are tucked away under a huge countertop for folding etc. Open area on the left side can be used for numerous purposes, such as hanging linen.
