I thought after s2 of Discovery, something exactly like that was already a thing?

Or am I misremembering, it’s been a while.

Holograms aren't stable in the long term. They will start to come apart after some time. That, and they constantly require power to maintain. A bed and furniture does not, and will still work if the ship needs to go without power for one reason or another. Most things someone might put by hologram can be done by replicating the thing, instead of using a hologram. Most rooms have a replicator, and excepting furniture, which you might need to ask engineering to make for you, you can just make it yourself.

Starships aren't lacking space by any means, so there's no need to stick people into a broom closet.

Though there are things like that. The Ba'ul "migration" ship was basically that, where the entire ship was meant to be a holodeck. In the 32nd century, rooms are basically holograms, except that holography has been superseded by programmable matter.

Power?

I imagine they prefer to be grounded in reality, as over-use of the holodeck is shameful.

Not everyone wants to sleep in a death trap.

Probably because it'd be too expensive and I'm not talking about money

I remember a line in at least one episode that claimed holodecks consume so much power, they run on their own independent power system and aren't connected to the warp core.

Can't remember which episode it was, but it was likely one of the two parters where the Hirogen take over Voyager and have the WW2 sim.

Maybe they are and nobody has realised 🤯

High energy use. Anytime the power goes out or gets diverted to other systems, you’d lose your bed, etc.

It’s also possible that the holodeck re-creations of things aren’t as realistic feeling as they look. It’s an illusion after all. So maybe a lot of it is just designed to fool the mind, not be comfortable/realistic.

As people said, the Holodeck uses a lot of energy, "Homeward" is an episode who show this.

Expensive?

In emergency cases most holograms can be shut off to match increased energy demands by weapons and shields.

Disengage the safety protocols and suddenly you've got weapons and shield emitters than ought to work just as well as their material counterparts, but can't be damaged (or any damage can be instantly reset). We know that holograms can be projected into space so the only limitation would be the range of the holoemitters.

1. Energy. In TNG, the holodecks burn a lot of energy. Can't imagine what would happen if you turned every room into one.
2. The holodeck isn't a Tardis. The space inside the holodeck is an illusion created by the room. The room can make the space look infinite, and the floor can function as a hard-light treadmill that let's you explore that infinite space, but the room still needs to be large enough to accommodate all the real-world things in it. That's why they're so large in TNG and Voyager. Holo-quarters would still need to be roughly the size of regular quarters.
3. Same problem with the bar. Sure, you could make anyone's quarters look like Ten Forward, but if your quarters fit 3 people, that's how many people can drink there.
4. The sickbay would still be essential because the problem isn't medical equipment, it's staff. Unless you're going to have the medical staff running all over the ship making house calls, having that staff in a centralized location and having the crew come to them just makes more sense, especially in an emergency. Emergencies are also why that equipment should never be holographic. If the ship is under attack, the last thing you want is sickbay disappearing because of a phaser hit or having to turn off the medical equipment to power the sheilds.

I thought the same. It helps to watch the first episode of the next generation. Will talks to wesely about it and its a rare thing at that time and sounds like it takes a lot of resources. Later episodes the holodeck using a lot of power comes up. People have to sign up for them and I took it there is no point in making more holodeck rooms than is prudent for the amount of power they draw just for leisure (mostly) activities. All the rooms have replicators but if someone was running it constantly it would become quite the power drain and we see in voyager that with no source of resupply have to ration replicators (although curiously I don't recall them rationing the holodecks, but maybe they did). As far as discovery in the future you see the energy issues and they use that programmable matter which I think is supposed to be more energy efficient.

Prodigy has holoemitters on every deck and is able to reconfigure the bridge using them. It is possible but they just need a reason.

They didn't go into depth at all, don't believe we even have one with a name, but they talked about seeing federation ships made entirely of 'holographic containment walls' in Discovery Season 3. Pretty sure it was when they first arrived at federation headquarters in the future.

There was also that ship in insurrection where it was just one giant holodeck, but still existing inside a regular ship. The concept just hasn't made it into something that's broadly popular in the mainstream trek fandom.

wait, does Discovery has a holodeck?

They actually seem to have what you're describing, more or less - Burnham was able to run complete holosimulations in her quarters.

I'd say the biggest reason is energy, like everyone else. But also, being able to make your room into any fantasy scenario you want would probably lead to problems with adjusting to everyday life. They don't need a whole ship full of Barclays screwing up at their job.
