Would you like to have single shower or twin showers?

And how many people is this bathroom for?

I was hoping for a bath. Would it be possible? It’s just a paper from a note pad lol

Show what surrounds it......as it will be one very inconvenient/tiny bath unless you find more space

Corner showers are great for small bathrooms.

There is such a thing as a sink attached tonthe toilet back. they use them in rvs and tiny houses. you could put a tub on the window wall and a toilet/sink on the left of the door wall.

another idea, tub and toilet inside the room with a sink outside the room. we had that setup in our first home.

One option works better, if the toilet is on an interior wall using an in-wall tank carrier. The other would require a bifold or outswinging door, most likely. Because of the swing. We can have 24" doors into baths here. If the room is very small there is no point having a wide door for accessibility because the bathroom has limited accessibility inside it anyway.

I think we need to know where the toilet is now for sure since moving toilets is a big deal. I need pictures of the space since th windows could be an issue or not .With no info all we do is guess .

Moving the toilet won’t be a big deal for me

The wall with the window is an exterior wall

The door is inswing 24” right now

I think I would go with Mary Lut's corner shower idea and swing the entry door towards the wall on the right.

If you really want a tub, I think Palimpset's tub against the window , toilet on left and a a small sink across from the toilet might work. I would swing the door to the right wall. If you get a vanity under 20 inches long and under 12 inches depth, you will have more room to maneuver around the sink upon entering the bathroom.

This one is 19 inches long by about 9 inches deep.

Marylut's design does not meet code. There needs to be 30" between the wall and the shower for the sink to go there.

If the doorswing is 24" swinging only 5" past the left wall, the second one would work with a regular door. You could not use my first one because of the in wall tank/carrier.

I usually like bathtub showers in small bathrooms that have a 60" dimension because you can go with a 60x29-30 tub and still have some sense of being able to move around if you use a shower curtain. I grew up with a 32 square shower and it was fine, but with a square enclosed shower the only thing you can not do is step out of the spray, like you can if you've got a rectangle to work with.

Local codes vary. Would help if you posted your local code requirements. Here you must allow 30” clearance in front of toilet, 24” is not enough. You also must allow about 7” clearance between wall and long side of toilet, and toilet tank can’t be on a wall shared with a BR.
