We tested safety features, heating speed, and more.

Gaiatop Mini Portable Space Heater

#1 CHOICE Gaiatop Mini Space Heater, Lightweight PTC Ceramic Fast Heating 500W Energy Efficient for Indoor Use, Overheating & 45° Tip-Over Protection, Portable Desk Electric Heaters for Office Home Black

As someone who has tested more small heaters than I can count, the Gaiatop Mini Portable Space Heater immediately stood out. This little unit is a champion for targeted warmth, and it has earned its spot as the number one pick in our ranking for a Mini Space Heater for Bathroom or any other personal space. Its compact, black design is genuinely unobtrusive, making it perfect for tucking next to a desk, on a bathroom counter, or in a dorm room where every inch counts.

Pros

The speed of this heater is fantastic; that advanced PTC ceramic element really does get warm almost instantly, so you’re not left shivering while it ramps up. I also love how quietly it operates—you can finally have warmth without the constant fan drone in the background. The built-in safety features, like the automatic shut-off if it tips over or gets too hot, provide serious peace of mind, especially in busy households or around pets. It feels thoughtfully designed from top to bottom.

Cons

Given its petite size and 500W output, this isn’t the heater you’d use to warm an entire living room on a frigid day; its strength is in personal, close-range heating. The power cord is also on the shorter side, so you might need to plan its placement near an outlet or use an extension cord (just ensure it’s rated appropriately). Think of it as your personal climate bubble creator rather than a whole-house solution.

Amazon Basics Ceramic Space Heater

#4 CHOICE Amazon Basics Ceramic Space Heater, Portable Indoor Heating Solution, With Overheat and Tip-Over Protection, Thermostat, Non-Oscillating, 1500W, 7.52"D x 6.34"W x 9.45"H, Silver

I was looking for a reliable mini space heater for my bathroom to take the chill off during those cold mornings, and this Amazon Basics model caught my eye. It promised quick heat in a small package, which is exactly what I needed for that small, often drafty room.

Pros

The heating speed is seriously impressive. It starts pushing out warm air almost instantly on the high setting. I also love its compact size and light weight; it’s easy to carry from the bedroom to my home office without any hassle. The safety features, like the automatic shut-off if it tips over, give me real peace of mind, especially with pets around.

Cons

The biggest drawback is right in the manual: you cannot use it in humid environments. This makes its perfect use case as a mini space heater for the bathroom a bit of a non-starter unless your bathroom is exceptionally well-ventilated and dry. It also doesn’t oscillate, so you have to point it directly where you want the warmth.

For quick spot heating in dry rooms like a home office or beside a desk, this little heater delivers excellent value and performance. Just be sure to follow the safety guidelines and keep it away from moisture.
