How can I use this empty space in my bathroom?

I would put a cabinet in the space that will fill it as much as possible. Enclose the side if needed but you probably want to leave access on the wall.

Slide some kind of wood to fit on the side to make a wall , and maybe one for the back but just so it fits in snuggly, in case something needs to be worked on and it can be removed.clean and paint everything white and use as more storage.

Depending on what the wires, pipes are for, if you'll need access to them for repair or something at some time, you'll at least want to mark the area some way so you'll know where to access it. But I'd wall off all sides and put in some sort of storage. If this space runs to the ceiling (hard to tell my photo), then put in a closet. If nothing else, a linen cabinet with shelves. Most homes never have enough storage! How big is this area? That might help give other ideas/

I like the built in hamper, I'd put another one in.

If wooden crates from the craft store would fit, ithat could be a quick and easy fix. You could slide two of them in there for easy in and easy out. Keep your toilet paper, personal supplies, cleaning supplies could go there.

Finish the sides and install the metal pull out wire shelves. You could then use the space for whatever you want to store.

Have a small access door for wiring and pipes. Wall it up put shelves, a closet rod, use for storage.

I don't know about your house but if this was in MY house, it would be a front door for mice. I would add walls inside this space to enclose it as suggested above and attach those walls with screws in case you ever need to access that plumbng or wires.

Once that is done and painted you could:

1. add shelves for storage, with or without a door.

2. Put your laundry hamper or waste basket in the open space.

3. Or a large basket for storage.

4. Make and hang a curtain over the opening.

If storage isn't needed add the walls inside and use the open space for decor; maybe something that has lights for a night light. Battery lights could be used.

Or simply close it with a panel of wall board of your choosing.

I want to express my deepest appreciation for the very thoughtful responses I have received.

Quick backstory on this home. I purchased it less than 6 months ago as a foreclosure. The previous owners walked away from their hard work of updating this 1925 farm house. They had an eye for the farm house decor that is prevalent today. They did some marvelous updates including corrugated tin ceilings, new wood vinyl flooring throughout, a generous pantry, large laundry/mudroom with a toilet, shower & plumbing for new sink. Unfortunately, every update was left incomplete. I call my new home "The Finisher Upper".

The utility wiring, etc., shown in these pics are for the new wiring & hoses for the new HVAC. The home has many of the original built-ins common for the day. In this bathroom alone, I have 1 built in drawer, 2 large built-in cabinets, 1 small closet & this space which housed the built-in hamper. I do believe turning this space into some sort of additional storage is ideal. I love the suggestions of making the back panel removable for future access to the wiring.

Again, thank y'all for your wonderful suggestions. I deeply appreciate the help!

Enjoy!

Secret door for access

I like Lorraine's idea about adding wood or something to make a wall and painting it. How about adding some built in or free standing shelves? Or maybe a full length mirror? Or install a closet rod for extra clothing storage? Just a few ideas. Take them or not as you wish.

drywall back of it,paint it & add shelving, maybe a recycled sliding barn door

I agree with Shore grandma's suggestion to put a hamper back in the space.

No more wet towels on the floor!

Picture 1 and 2 show a purchased slider box shelf, 3 and 4 a wire slider.

Picture 4 shows a standard small trash bin, which could easily be used as a hamper, or as a garbage. If you did not want it to be on view, put the door back on the cabinet.

Hello, you could finish off the inside of this space with some wall panels or drywall, then put a shelf like this attachment has in.

Put a sheet of plywood over and paint. You can put a hamper or toiletries if you add shelves.

Obvious answer would be for storage since there never seems to be enough in the bathroom. Great place to store towels, blankets, sheets, etc.

Panel out the back to hide the pipes etc. (Use Screws incase you ever need access). Then add shelving for Linen, Towels etc. and space or Storage bins for Dirty Linen

Add Louvre doors to close it off.
