Leviton Countdown Timer DT160-1LW – 10/20/30/60 Min

The Leviton DT160-1LW timer switch automates bathroom fan and lighting loads with four preset durations: 10, 20, 30, or 60 minutes. When pressed, the device powers the circuit and automatically shuts off after the selected interval, preventing overuse of exhaust fans and lights. It supports up to 600W LED/CFL lighting, 1800W incandescent/halogen, and 1/2 HP fans, with a 15A rating for resistive loads. The device is designed to fit shallow wallboxes for easy retrofitting. A ground connection is required; it includes a Green Flex Sleeve to facilitate grounding where no neutral is present, or can be removed to connect to a neutral wire if available. Installation notes emphasize a ground wire for safety.
Leviton DT130-1LW Countdown Timer – 5/10/15/30 Min

This Leviton DT130-1LW timer switch offers four preset countdown options (5, 10, 15, 30 minutes) to automate fan or light runs in bathrooms and other spaces. Like the DT160, it features a compact profile suitable for standard wallboxes and supports 600W LED/CFL lighting, 1800W incandescent/halogen, and 1/2 HP motors. The Green Flex Sleeve provides an option for grounding even when no neutral is present, with a ground wire required for safe operation. It is designed for quick replacement of existing switches with minimal wiring changes.
ENERLITES Countdown Timer Switch – 1–30 Min

ENERLITES offers a 1 to 30 minute countdown with a neutral wire requirement. This timer switch is suitable for controlling bathroom lights, exhaust fans, and other loads. It replaces a standard wall switch to automate shut-off after the pre-set duration. The unit supports a broad range of lighting and fan loads, making it a flexible option for energy savings and consistent use in smaller bathrooms or utility spaces where timer control is beneficial.
Lutron Maestro MA-T51MN Countdown Timer

Lutron’s Maestro MA-T51MN-WH provides a versatile countdown timer for fans and lights in both single-pole and multi-location configurations. It supports energy-efficient DC and high-efficiency exhaust fans in bathrooms, helping reduce energy use without sacrificing convenience. The timer can function as a countdown for lights or fans, ensuring bathrooms aren’t left running unintentionally. It integrates with Maestro accessories for multi-location setups, though separate components may be needed for full multi-point control.
BN-LINK Digital Countdown Timer – 5/10/20/30/45/60 Min

The BN-LINK digital timer offers six preset durations (5, 10, 20, 30, 45, or 60 minutes) with a wall plate included. It supports repeat functionality for daily automation and a manual ON/OFF option to override settings. This makes it suitable for bathrooms where consistent timing is desired for fans and lights, while the neutral-required design ensures compatibility with a wide range of wiring configurations. The timer emphasizes energy savings by automatically turning off after the countdown ends.
BN-LINK Mechanical 60-Minute In-Wall Timer

This BN-LINK mechanical timer provides a straightforward 2 to 60-minute adjustment via a knob, delivering precise shut-off control without electronic components. It is a robust option for bathrooms and utility rooms where a simple, durable timer is preferred. No neutral wire is required, and the included dual-wall plates fit standard installations. The device supports a range of lighting and small appliances, making it a practical choice for basic timer needs.
Buying Guide: Key Purchase Considerations
When selecting a bathroom fan timer, consider compatibility with your wiring and loads, ease of installation, and the type of timer (digital vs. mechanical). If your wallbox lacks a neutral wire, choose a model explicitly designed for no-neutral installations, like some Leviton options, to avoid rewiring. For LED or CFL lighting, ensure the timer supports the wattage and load type to prevent device overheating or nuisance tripping.
Presets and customization matter: digital timers typically offer multiple presets (5–60 minutes) and may provide repeat functions for daily routines. Mechanical timers provide full-range timing but lack digital precision. In multi-location or smart-home setups, Lutron Maestro or compatible accessories can be advantageous, though you may need additional components for full integration.
Installation ease is also a factor: some timers are designed to replace standard switches with minimal wiring, while others may require neutral wiring or ground wiring verification. Pay attention to load ratings (watts, amps, and motor horsepower) to ensure safe operation for your bathroom fan and lighting combination. Finally, evaluate aesthetics and plate compatibility to match existing switches in style and color for a cohesive look.
