In winter, water is often harder for birds to find than food. A heated bath that stays open through a freeze is one of the best things you can do for backyard birds, and it is cheap and low maintenance.
The short answer
- Simple and cheap: Farm Innovators heated bath.
- Deck rail or small space: Allied Precision.
- Already have a bath: a drop-in de-icer.

How to choose
Heated bath or de-icer
A heated bath is an all-in-one solution. A de-icer lets you keep a bath you like, but check that it fits.
Power and safety
You need an outdoor outlet. Use an outdoor-rated extension cord and a GFCI-protected outlet, and keep connections dry.
Depth
Keep the water shallow, about one to two inches at the deepest.
Placement
Place it near cover, in a spot that gets some sun and where you can see it. Keep it away from windows to reduce collisions.
Cleaning
Scrub the bath regularly, even in winter, and refresh the water.

Frequently asked questions
Do birds need water in winter?
Yes. Birds need drinking water year-round, and in freezing weather most natural sources are frozen. A bit of open water is often more attractive than extra food.
Is it safe to leave a heated bird bath on?
Heated baths are designed to be left on outdoors, and many have thermostats that switch the heater on only when needed. Use an outdoor-rated cord and a GFCI outlet, follow the manual, and keep the water shallow.
Can I add antifreeze or salt to a bird bath?
No. Antifreeze is poisonous and salt is harmful to birds. Use a heater or de-icer to keep the water open instead.
How deep should a bird bath be?
Most small birds prefer water about one to two inches deep at the deepest, with a gently sloping edge or a rock they can stand on.
