Turn on the shower in a Costa Rican guesthouse and you may find wires running into a plastic showerhead. That’s an electric shower, and it’s normal here.
Costa Rica’s electric showers, called duchas eléctricas locally and nicknamed “suicide showers” or “shock showers” by travelers, heat water inside the showerhead as it flows through. They’re common in homes, budget hotels, hostels and rural cabins because they’re cheap to buy and don’t need a water tank or gas line. Are they safe? A properly installed unit, grounded and on its own circuit breaker, is generally safe to use. The risk comes from poor installation, so check the setup, run the water before the heat, never touch the head or change the setting while it’s running, and report any tingle or exposed wiring to your host.
This guide explains how electric showers work, the warning signs and how to use one safely.

How it works
What Is an Electric Shower?
An electric shower is a small on-demand water heater built into the showerhead. Cold water enters the head, passes over an electric heating element and comes out warm. There’s no tank and no wait. Most units have a switch or knob with settings like hot, warm and off, and the head is wired to the building’s electrical supply. In older or DIY installations, those wires are often visible.
Because the element puts out a fixed amount of heat, less flow means hotter water. Turn the tap down for more heat and up for cooler water.
Why they’re common
Why Costa Rica Uses Electric Showers
- Cost: an electric showerhead is far cheaper to buy and install than a tank water heater.
- No gas network: Costa Rica has no piped natural gas to homes, and propane is mostly used for cooking.
- Warm climate: in the lowlands and on the coasts, many people shower in cool water, so a small heater is enough.
- Space: there’s no tank to fit, which suits small homes and cabins.
Newer homes, larger hotels and most resorts use tank or tankless water heaters instead. You’ll mostly find electric showers in budget lodging, hostels, rural areas and older buildings. If it matters to you, ask your hotel or vacation rental before you book.
Safety
Are Electric Shower Heads Safe?
When they’re installed correctly, yes, for normal use. Manufacturers require the unit to be grounded with its own ground wire, never the neutral, and fed by a dedicated circuit breaker with cable sized for its power. Units come in 110–127 volt and 220–240 volt versions, and the voltage must match the supply.
The problems come from shortcuts: no ground wire, undersized cable, taped splices or a breaker shared with other outlets. In those cases, you might feel a tingle from the head, the tap or even the water. That isn’t normal, and it isn’t safe.
Warning signs before you shower
- Bare copper or wires joined with tape near the head
- No green or green-and-yellow ground wire
- Scorch marks, melted plastic or a burning smell
- Water dripping from the wiring connection
- Sparks, buzzing or a breaker that trips repeatedly
How to use it
How to Use an Electric Shower Safely
- Look first. Check the wiring and the head for the warning signs above before you turn anything on.
- Set the heat with the water off. Choose hot, warm or cold while the tap is closed. Manufacturers say not to move the selector while the shower is running.
- Turn on the water. The heater switches on when water flows through it. Running water first also protects the heating element.
- Adjust with the tap, not the head. For hotter water, reduce the flow a little. For cooler water, open it up. Don’t touch or move the showerhead while it’s on.
- Turn the water off before you get out, and before you change the setting again.
Expectations
What to Expect From the Water
- Lukewarm, not hot: most units warm the water rather than heat it like a tank, especially with good water pressure.
- Low pressure for hot water: the trade-off is a gentler stream when you want it warmer.
- Cold at altitude: in Monteverde, the Central Valley highlands and other cool areas, a weak electric shower can feel chilly. Ask about hot water when you book.

Good to know
Costa Rica Electric Shower FAQ
What is a suicide shower in Costa Rica?
It’s the traveler nickname for an electric shower, a showerhead with a built-in electric heater. Locals call it a ducha eléctrica.
Are electric shower heads safe?
Generally, yes, when they’re grounded and on a dedicated circuit breaker, as manufacturers require. Poorly wired units can give shocks, so check the setup and report any tingle.
Can you get electrocuted by an electric shower?
A badly installed or damaged unit can give a shock. Properly installed units are designed to prevent it. If you feel anything, turn off the water, get out and tell your host.
How do I make an electric shower hotter?
Set it to the hottest setting with the water off, then turn the water on and reduce the flow. Less water passing through means hotter water.
Why don’t Costa Rican homes have water heaters?
Many do, but electric showers are cheaper to install, need no tank or gas line, and suit the warm climate in much of the country.
Do hotels in Costa Rica have electric showers?
Some budget hotels, hostels and cabins do. Most larger hotels and resorts use conventional water heaters. Ask before booking if it matters to you.
The short version
Electric showers heat water in the showerhead and are common in Costa Rican homes and budget lodging.
A grounded, properly wired unit is generally safe. Set the heat with the water off, adjust with the tap, don’t touch the head while it’s running, and report any tingle.
