A ground wire is required for safe operation. This model is well-suited for bathrooms needing discreet control over exhaust fans and lighting with minimal wiring complexity.
BN-LINK 60-Minute In-Wall Timer

The unit is designed for quick replacement of existing switches and fits single or multi-gang decorator or toggle plates. This option provides a straightforward, budget-friendly path for automatic shutoff of bathroom fans and lights, helping reduce energy usage when timers are all that’s needed to prevent devices from staying on too long.
Leviton Countdown DT160-1LW
The DT160-1LW from Leviton expands on the DT130 with 10, 20, 30, and 60-minute presets, maintaining the no-neutral requirement and a shallow wallbox profile. It supports similar electrical loads for fans and lighting as the DT130, including 600W LED/CFL and up to 1,800W incandescent. The Green Flex Sleeve continues to facilitate grounding in boxes without a neutral. This model is ideal for users who want a wider range of preset durations without adding neutral wiring complications.
Fosmon Countdown Timer Switch
Fosmon offers a 2-pack programmable timer switch with 9 settings and a 5-60 minute range, plus 1-2-4 hour countdown options. It requires a neutral wire and includes an illuminated button along with a blue LED program indicator for visibility in dark bathrooms. The device is designed to be compatible with standard single- or multi-gang boxes and can control bathroom fans, heaters, or lights, helping ensure devices shut off as planned and improving energy efficiency.
ENERLITES 1-30 Min Countdown Timer (HET06A)
ENERLITES’ HET06A 1-30 minute timer provides neutral-wired control for a range of bathroom appliances. It features six preset options (1, 5, 10, 15, 20, 30 minutes) and includes a manual override. This model is UL-listed and ideal for users who prefer a device with a blue LED indicator and a neutral-required configuration, suitable for fans, lights, and small motors in bathrooms or laundry areas.
Leviton DT104-1LW Countdown Timer
Leviton’s DT104-1LW focuses on a 30-minute preset along with 1-2-4 hour options, still without Neutral, and features a compact form factor for in-wall installation. Compatible with 600W LED/CFL and 1/2 HP/9.8A fan loads, its Green Flex Sleeve offers safe wiring in neutral-absent boxes, though a ground is required. This model suits users who want a classic timer experience with a broader set of short to mid-range durations.
Buying Guide: Timer Switches For Bathrooms And Heaters
When choosing a timer switch for a bathroom heater or exhaust fan, several factors affect performance and compatibility. Consider the following:
- Wiring needs: No-neutral options simplify retrofits in older homes, but some models require a neutral wire for full functionality. Check your wall box wiring before purchasing.
- Load compatibility: Verify the maximum load rating (amps and horsepower) to ensure the switch can safely control your fan or heater without overheating.
- Preset options: Decide if you need 4 preset durations or a wider range (like 6 or more). Short durations are common for fans; longer presets help with heaters or lights timed for extended use.
- Grounding and safety: Models with Green Flex Sleeve offer easier grounding in certain setups. If a ground wire is not available, ensure the installation method complies with local codes.
- Indicator features: LED indicators and illuminated buttons help locate and operate the switch in dim bathrooms or at night.
- Size and fit: In-wall compatibility matters. Choose a shallow design that fits your wallbox and matches your plate style (decorator or toggle).
- Energy savings: Timers reduce energy waste by ensuring devices turn off on schedule. Consider whether you want manual override options for flexibility.
Additional considerations include multi-pack options for homes with several bathrooms, UL or UL-listed certifications for safety, and whether the unit supports both lights and fans on a single switch or separate controls per room. Evaluating your typical bathroom routine and appliance load will help select the most suitable timer configuration for reliable, hands-off operation.
