it quickly fills up with leaves and debris.

Could you cut a small hole in the bottom of the wall, which would allow you to sweep out the leaves and debris?

It’s not pleasant to sit out there, it’s like sitting in a cave.

I think it could be pleasant. I'd consider covering the wall with tile -- I'm thinking something with a Mexican influence -- then two nice comfortable chairs. Let the naked sunbathing begin!

How about a hot tub for two?

How about flowers -- even a small tree -- in a container garden?

I don’t think we would use an outdoor shower. It’s so weird!

That was going to be my suggestion! I'd totally use it.

A fountain would provide you with both a nice visual plus the sound of water. Remove some of the pavers to allow for planting and it could be very charming.

What is on the other side?...cut a large glassless window?

Lizards and probably snakes too would prompt me to tear it down. They can easily hide in the garden.......Good Luck.

There is so much potential for this space! It doesn't have to be wasted anymore. I like the materials used in Grover's San Fransisco pic. with an added fountain and small bistro set. Nice visual view and soothing water sounds. Leave the slider open at night for the sound and have coffee out there on your days off.....yes please!

So is the only access through your bedroom? Yeah, I wouldn't want to schlepp dirt and water through my bedroom for plants.

Mexican tile on the wall with a wall fountain could be nice ttps://mymexicantiles.wordpress.com/2017/01/19/mexican-tiles-outside-walls/

Since you already have the stucco wall you could achieve this look with a fountain http://www.mexicantiles.com/media/images/talaveraTiles/30060-4.jpg

Oh, man. I'd reconsider the outdoor shower. Here's a link to designer Lauren Liess' old garden/shower off her master bedroom. https://www.laurenliess.com/pure-style-home/our-bedroom-secret-garden-before-after

When you look out there, what would you like to see? A fountain? Plants? Decorative tiles on the wall? A quiet place to sit?

We can come up with 3 million ideas, but YOU will have to decide what you want. What will make your heart sing? What will make you think of that space and the time you can spend out there.

You can schlepp the dirt and plants OVER the wall !!!

No breezeI'm guessing. I would get rid of the curved wall and have a seating area. Nothing you do will stop the leaves or lack of a view/breeze except that. guess

If you remove the wall, you can see the sky and trees. If you leave it there, you'll have to solve the drainage and leaf problem.

See C&B for circular outdoor sectionals.

Use the reverse action on a leaf blower to suck up debris and deposit in attached bag for clean up.

make it something to look at even if not a place to sit in. and its a great private light well.

but i guess one is either a secret garden sort of person or not. those that arent cant imagine the attraction, those that are are salivating all over their keyboards.

I see two choices here. If there is a view outside that wall, I'd tear it down, clean up or replace the patio floor, and add a chair or two to enjoy morning coffee and evening wine when the breezes are pleasant.

If the wall provides needed privacy, I would turn it into a space for viewing only. I can't imagine it's pleasant to sit out there with no air movement, and you already have a lanai. A fountain and plants--visit the horticulturist at the best nursery in town to see what will grow there--with some dramatic up-lighting at night would provide a serene accent to the room.
