How fast does it heat a room?

It uses a fan to push heated air out, so you feel warmth within a minute or two of switching it on. A small bedroom or office reaches a comfortable temperature faster than a large open living area.

Does the thermostat actually hold a temperature?

Yes. You set a target temperature and the heater cycles on and off to hold it, rather than running flat out. Expect the room to drift a degree or two around the setting.

The fan is audible, and more so on higher heat settings. It is fine for a living room or office but may bother light sleepers in a bedroom.

Can I use it in a bathroom?

Only if it is rated for damp locations, which this type of portable fan heater generally is not. Keep it in dry rooms and away from water.

The heater itself with its attached cord and plug, plus the manual. No remote or extra parts are included.

How does it compare with a ceramic tower heater?

Both heat a single room fast. A tower heater spreads air over a taller grille and often adds oscillation, while this 16-inch unit is more compact and simpler to place.
