If there's enough head room then putting the toilet under the stairs could work. I like the layout you suggest with the tub/shower on the 6' wall and sink on the longer wall. Or you could possibly find a way to use the area under the stairs for storage.

Then maybe shift the W/D to next to the window which gives the toilet more room to face the way it was. Put the shower next to the door with a narrow linen closet separating it from the W/D. Maybe add a stackable small laundry closet there and still have a very large closet. In both of these cases, it seems like the w/d would cover up a window, which I was hoping to avoid. It's a row home with other taller buildings around it, so I like to keep as much light as possible. Do you think it's worth covering up the window anyway? It is more inconvient, disruptive and expensive to change your toilet location in reality. I didn't actually move the toilet flange location, I just rotated the toilet and changed it to a 14 inch rough-in instead of the 10 inch version I currently have. (Specifically looking at the Kohler Wellworth Classic Five.) My cursory googling seemed to indicate this was ok. Is that a bad idea? If you had a spacious well layout bath you might find your closet is no longer your favorite room, I sure did. The shoes and bags live in the closet, so I don't think that's ever going to change! Haha! :)

We just finished the layout stage of our basement renovation. Our basement is almost exact the same size as yours so I'm very interested in seeing your progress! We chewed on plans and ideas for more than a year. We only came up with a layout we both feel good with once we finally figured out what we really want to use the basement for and what should be possible in the future. Our house is one bedroom short for our family so we really need a bedroom or sleeping area in the basement. Our house only has one bathroom (one toilet) for 5 people so we need an extra bathroom too. We have an exit to the garden in the basement so we wanted to have some kind of mudroom, laundry and mechanical room needed to stay downstairs too. First we thought of making a bedroom for or oldest son. But the square footage we have to work with is not big and making a bedroom, bathroom, mudroom and mechanical room would divide the space in a lot of little rooms and a hallway which takes in space as well. Furthermore, in this area basements are typically used for recreational functions. So we fear the resale value of our house might decrease with no obvious recreational space down there. We decided to turn the basement into an open concept bedroom/office for ourselves and have the bathroom for ourselves too. This way the basement will be our own little studio, the kids will each have a bedroom and one bathroom upstairs. When the time comes that our kids move out, we can simply take our bed out of the basement and replace it with a couch or two to turn it into a recreation room. I hope this can help in some way! Maybe you too can combine the functions of the rooms you want, like: bathroom/laundry or recreation room/guestroom ? This is roughly the new layout of our basement, the dimensions of stairs and doors are a bit off but you'll get the idea :)

are there bedrooms down there as well? if someone will be using the bedroom in the basement, then they will want a decent bathroom to go with it. 6 inches really isn't worth the hassle of taking down or moving a wall. A foot, maybe, 6" ? no. once you put on the wall or tile, you've got maybe 4" total. Maximize the space by choosing a good vanity w/storage, and possibly building a niche into the wall for additional storage. (use the area between the studs as a built in cabinet) using a prefab shower is fine, but pick a decent one as opposed to those flimsy acrylic pieces. you don't say want the resale value is, so i have no way of knowing how much you should invest. You say you bought mid-range, but I don't know what else you need to redo. anything under a 15% profit really isn't worth it. as for fitting it over the existing drains, usually you will need the new drain cover. if the drain needs to come up, there are extensions. I would advise your husband to do some research on how to fit those into an existing bathroom. If he's handy and can build his own slope, mortar bed and waterproof the shower, then he could prob tile it himself. Just depends on how much work you want to do and what the return is on what you choose. by the looks of what you have there currently, you may have some water damage underneath all the mess. Tear out what you can and then determine what you need to do.
