Check Price on Amazon

The Broan-NuTone FG600 redefines what a bath fan cover can do by integrating a 750-lumen LED array directly into the grille. Rated at 3000K with a CRI of 80, it bathes the bathroom in warm, natural light without the dim glow of a separate bulb-and-diffuser setup. The pass-through plug design lets you daisy-chain the fan motor through the grille, so installation takes less than five minutes with zero wire nuts.

Fewer ventilation slots aren’t just a design choice — they reduce the surface area where dust and moisture accumulate, helping the white finish stay bright years longer than grilles with dense slot patterns. At 16 ounces, the unit feels substantial and the baffle-style filter dampens motor noise noticeably compared to skeleton-style covers. Replacing a 28-year-old Broan fan cover with this unit immediately modernizes the room’s lighting and air extraction.

Compatibility is the only catch: the FG600 requires a Broan or NuTone housing with a standard pass-through receptacle. It does not work with spring-mounted frames or third-party housings. Measure your existing cutout at 9.75 x 10.25 inches before ordering. For anyone willing to confirm fitment, this is the single most transformative upgrade a bathroom vent can receive.

Designed for NuTone models in the 663, 669, 763, and 770 series, this grille-and-lens assembly restores the factory appearance of fans that attach via a reflector and wing nut rather than springs. The grille measures 12.125 x 10.75 inches, and the separate lens covers a 10.75 x 5.125-inch area — the exact dimensions needed to diffuse light from an exposed A19 bulb. Owners of 15-year-old units regularly report that the swap takes under two minutes with just one wing nut.

The plastic construction feels more rigid than many budget covers, and the white surface resists the yellowing that plagues original 2000s-era parts. Unlike spring-loaded options, this grille stays locked in place via the metal reflector, so there’s zero risk of it sagging or popping loose over time. The cutout does not include springs or a lens frame — it relies entirely on the existing housing hardware to stay secure.

Critical note for buyers: this assembly does not fit models 655–659 or the B695/B696 series. If your fan uses springs to hold the grille, this part will not attach. The reverse side of the grille confirms this with a molded compatibility list. For any NuTone fan with a reflector-and-nut mounting system, this is a direct OEM-quality refresh.

Targeting Broan-NuTone models 655, 656, 657, 659, 695, and 696, this two-piece kit replaces both the outer grille and the plastic light lens in one box. The ABS material is noticeably stiffer than the polypropylene used in budget grilles, and the lens is manufactured with a higher translucency that eliminates the dim, yellowed output of original covers from the 1990s and 2000s. Installation involves removing the existing reflector and bulb, placing the new grille, then snapping the lens into place.

Owners of vintage 659 units (often found in 1970s and 1980s homes) report the grille is slightly larger than the original, which actually helps mask imperfections in the ceiling cutout. The powder-coated finish resists the chalky oxidation that develops on older ABS parts exposed to decades of steam. The kit ships without a bulb, so you’ll need a standard A19 LED to complete the light upgrade.

The assembly uses forced air movement around the lens, so there is no risk of overheating the LED bulb. Buyers should note the grille does not include springs — it fastens via the existing reflector hardware. Double-check that your housing uses a removable reflector plate before ordering. For anyone dealing with a yellowed, brittle cover on a classic NuTone fan, this kit delivers an authentic refresh at a fraction of OEM part prices.

This two-pack targets the most common Broan-NuTone housing sizes — models 663, 670, 671, 675, 688, and 689 — with a 9.25 x 9-inch grille designed to fit a 7.25 x 7.5-inch internal opening. The bright white finish matches standard ceiling paint and the spring clips are pre-attached, reducing installation to a single press-up motion. Owners of bathrooms with multiple fans can renew both rooms without ordering separate parts.

The plastic feels denser than single-pack budget covers at similar per-unit cost. The flat face design sits nearly flush with the ceiling, avoiding the recessed look of older, deeper grilles. Airflow remains unrestricted because the stepped slot pattern creates a 360-degree intake path that prevents the motor from starving for air. Users with older NuTone HD80NT housings have confirmed the 9-inch dimensions line up correctly, though some report the springs are shorter than OEM parts and may require swapping original springs for a perfect tension fit.

The only drawback is the flat profile — if your fan motor or wiring box extends below the dryline, the grille may not sit flush against the ceiling. In those cases, adjusting the fan mounting bracket slightly solves the issue. For standard-height installations, this two-pack offers the best per-unit value among spring-loaded grilles.

Built for 12-inch-square openings, this cover uses thickened ABS plastic that resists the warping common in thin polypropylene grilles exposed to continuous bathroom steam. The 7-inch spring spacing matches most large-commercial-style fan housings, and the package includes a pair of 9-inch extended springs plus non-slip gloves to assist with overhead installation. The stepped grille design distributes airflow uniformly, which prevents condensation from pooling in one corner of the duct.

Buyers with NuTone 671 housings confirm the larger face (12 x 12 inches) provides ample coverage to hide ragged drywall edges left by a previous oversized cutout. The hinge slot locations align with OEM patterns, making it a drop-in replacement for many 2000s-era large fans. The included mold strips can be applied to the rear lip for a tighter seal, improving ventilation efficiency by reducing air bypass around the edges.

Some users note the plastic, while thicker than entry-level options, still flexes slightly when pressure is applied at the corners. The finish is pure white with a painted texture that matches ceiling paint more closely than glossy alternatives. If your fan opening measures a full 12 inches in both directions, this cover eliminates the gap problem caused by 11.5-inch panels sold as “12-inch” covers.

At under 13 dollars, this polypropylene 12×12-inch panel covers oversized openings that smaller 9-inch grilles would leave exposed. The 0.3-inch thin profile sits nearly flush, and the matte finish avoids the high-gloss shine that highlights ceiling texture imperfections. Two pairs of springs at 7.5-inch and 11.6-inch spacing accommodate different clip locations inside larger commercial-grade fan housings. Buyers replacing old 1990s fan covers report the wider spring pair often works where single-spacing covers fail.

The stepped grille design maintains 360-degree intake, preventing the restricted airflow that flat panels sometimes cause when the filter area is too small. Several users note the cover looks better than the original plastic it replaced — cleaner lines and a brighter white that instantly lifts a dated bathroom ceiling. The spring attachment is straightforward: push the cover up until the hooks grab the housing clips, then release.

Where this cover falls short is material rigidity: the PP plastic flexes more than ABS when inserting into tight openings, and some owners with non-standard clip inserts found the spring hooks didn’t capture securely. Older homes with irregular mounting points may need a dab of silicone or a shim to keep the panel flush. For standard-level big-box fan replacements, this is a cost-effective solution that beats leaving bare wires exposed.

The FGR101 is the entry-level workhorse for Broan and NuTone fans with a 7.5 x 7.25-inch housing opening. The outer dimensions of 9.75 x 9.25 inches overlap the ceiling cutout enough to cover minor drywall imperfections, and the bright white finish matches standard ceiling paint out of the box. Installation is a true snap: align the springs with the housing clips and push up — the grille locks in place without tools, screws, or adhesive.

Compatibility spans models 670, 671, 688, 689, 695, 696, 771, E050, and E070, covering at least three decades of Broan-NuTone production. The low-profile design keeps the grille within 1 inch of the ceiling, which eliminates the protruding “nipple” look of older deep-dish covers. Users consistently report zero rattling because the spring tension holds the plastic tight against the housing rim.

The plastic is lightweight and does not have the same impact resistance as the ABS on premium covers, but at this price point, replacing it every few years is still cheaper than a single premium panel. Some buyers note the springs are shipped compressed in the packaging, which can cause them to lose tension over time if the grille sits in a hot attic space before installation. If your old cover is simply yellowed or cracked, the FGR101 restores a factory-clean look with minimal effort.
