Bathroom outlets are not always 15 or 20 amp. The outlet itself may be a different size and the amperage may vary depending on the home’s wiring. Always check with an electrician to see what size and amperage your bathroom outlets are before attempting to use them.
This is a question that we get asked a lot here at our store. The answer is actually both! Depending on the age of your home, bathroom outlets can be either 15 or 20 amp.
The code used to require that all new homes have 15 amp outlets in the bathrooms, but that has since changed and now 20 amp outlets are required. So, if you’re not sure which amperage your bathroom outlet is, just check the label on the outlet itself.

How Do You Tell If Outlet is 15 Or 20 Amps?
How do you tell if outlet is 15 or 20 amps?
There are a few ways to tell if an outlet is 15 or 20 amps. The most obvious way is to look at the outlets themselves.
If they are labeled 15 or 20, then that is their amp rating. Another way to tell is by looking at the circuit breaker that controls the outlet. The circuit breaker will be either 15 or 20 amps as well.
Do Bathroom Outlets Need to Be 20A?
Bathroom outlets do not need to be 20A. The National Electrical Code (NEC) requires that all dwelling units have at least one 120-volt, 20-amp circuit for bathroom receptacles. However, this does not mean that all bathroom outlets must be 20A.
You can install 15- or 20-amp circuits in your bathroom, as long as they are protected by a ground fault circuit interrupter (GFCI).
Can You Put a 20 Amp Gfci on a 15 Amp Circuit?
Yes, you can put a 20 amp GFCI on a 15 amp circuit. The GFCI will protect the circuit from overload and provide ground fault protection.
Can You Replace a 15 Amp Receptacle With 20 Amp?
If you’re asking if you can *legally* replace a 15A receptacle with a 20A one, then the answer is no.
The National Electrical Code (NEC) does not permit the substitution of a 20-amp receptacle for a 15-amp one unless the circuit wiring is also upgraded to 12 gauge or larger size wire. The NEC requires that circuit breakers and fuses protecting against overloads be properly sized for the amperage rating of the circuit being protected.
Therefore, installing a 20-amp receptacle on a 15-amp circuit breaker or fuse will create an unsafe condition because the overcurrent protection devices are not properly sized for the increased load.
Can I Use 15 Amp Gfci in Bathroom
There are a few things to consider when deciding if you can use a 15 amp GFCI in your bathroom. The first is the size of the room. If your bathroom is small, then a 15 amp GFCI should be fine.
However, if your bathroom is large, you may need a 20 or 30 amp GFCI.
The second thing to consider is the number of outlets you have in your bathroom. If you only have one outlet, then a 15 amp GFCI will probably be sufficient.
However, if you have multiple outlets, you will likely need a higher amperage GFCI.
The third thing to consider is the type of appliances or fixtures you have in your bathroom that could potentially cause a problem with a lower amperage GFCI. For example, if you have a hair dryer or curling iron that draws a lot of power, you will probably need at least a 20 amp GFCI.
In general, it is best to err on the side of caution and go with a higher amperage GFCI than what might be required for your particular situation. This will ensure that all of your devices and appliances are protected from electrical shocks and other hazards.
Electrical Code for Bathroom Outlets
Bathroom outlets must be GFCI protected. This means that they have a ground fault circuit interrupter built in to the outlet itself, or are connected to an outlet with a GFCI breaker. This is important because bathrooms are one of the most common places for electrical accidents to occur.
GFCI outlets work by constantly monitoring the current flowing through the circuit. If there is any imbalance, such as if the current starts flowing through a person instead of just through the wires, then the GFCI trips and shuts off power to the outlet. This prevents electrocution and other serious injuries.
There are two types of bathroom outlets: those that are hardwired, and those that plug into an existing outlet. Hardwired outlets must be installed by an electrician, while plug-in outlets can be installed by anyone.
Most new homes are required to have all bathroom outlets be hardwired GFCIs, but older homes may still have non-GFCI outlets.
It’s important to check all of your bathroom outlets and make sure they are properly protected. You can buy a GFCI tester at any hardware store; simply plug it into the outlet and push the test button. If the outlet is not GFCI protected, you’ll need to have an electrician install a new one for you.
Are Outdoor Outlets 15 Or 20 Amp
In most cases, outdoor outlets are 15 or 20 amp. However, there are a few factors that can affect this. For example, if the outlet is being used for high-powered equipment such as a air conditioner or pool pump, it may be 30 amp.
It’s always best to check with your local building code to be sure.
Conclusion
There’s a lot of debate among electricians about whether bathroom outlets should be 15 or 20 amp. The National Electrical Code (NEC) requires that all 120-volt, single-phase receptacles in wet locations be protected by a ground fault circuit interrupter (GFCI). However, the NEC does not specifically require GFCIs in 15-amp circuits.
Some electricians argue that since the NEC does not require GFCIs in 15-amp circuits, then bathroom outlets should be 15 amp. They argue that if there was a problem with the outlet, it would be easier and cheaper to replace a 15 amp outlet than a 20 amp outlet.
Others argue that bathroom outlets should be 20 amp because they are typically used for devices that require more power, such as hair dryers and curling irons.
They also argue that if there was a problem with the outlet, it would be less dangerous to have a 20 amp circuit than a 15 amp circuit.
The bottom line is that it is up to the individual electrician to decide whether bathroom outlets should be 15 or 20 amps.
