18" x 30" Mirrors | Bobrick B-1658 Tempered Glass Series | Bobrick B-165 Standard Glass Series

Schools, healthcare facilities, gyms, transit hubs, and other high-impact commercial restrooms commonly specify tempered glass mirrors instead of standard float glass — tempered glass resists breakage and provides a measure of safety from broken glass. The Bobrick B-1658 1830 is an 18" W x 30" H tempered glass channel-frame mirror that combines two features: 1/4" tempered glass for impact safety, plus the channel-frame design's frame screw that permits replacement of the glass if the mirror is damaged. Built around a one-piece Type-430 stainless steel channel frame with a bright-polished finish, the B-1658 1830 mounts to a concealed wall hanger / bracket system designed to keep the mirror secured against the wall. As a Bobrick Premier Partner, Total Restroom stocks the B-1658 series with Low Price Guarantee and 48-Hour QuickShip on in-stock sizes.

Key Features

1/4" Tempered Glass for Safety in High-Impact Areas

The B-1658 1830 uses No. 1 quality, 1/4" (6 mm) tempered select float glass, selected for silvering and electrolytically copper-plated by the galvanic process. Tempered glass mirrors resist breakage and provide a measure of safety from broken glass. That makes the B-1658 the right specification for schools, healthcare facilities, gyms, transit, and any other commercial environment where impact resistance is a priority. Note that tempered glass differs in color and reflective quality from standard glass mirrors — see the manufacturer note below.

Field-Replaceable Glass — Channel-Frame Advantage

What separates the B-1658 from welded-frame tempered glass mirrors is the channel-frame design's frame screw, which permits replacement of the glass if the mirror is damaged. Welded-frame tempered mirrors (like the B-2908) typically require replacing the entire unit. For high-traffic facilities where mirror damage is a recurring maintenance line item, the B-1658's combined tempered glass + field-replaceable design can help reduce lifetime maintenance cost compared with full-unit replacement.

Type-430 Stainless Channel Frame, Bright-Polished

The frame is roll-formed Type-430 stainless steel with a bright-polished finish — the same higher-shine, more reflective look as the standard-glass B-165 series. Type-430 is commonly used for indoor commercial fixtures where a bright-polished stainless appearance is desired. The 90° mitered corners give the channel frame a clean, architectural edge.

Concealed Wall Hanger / Bracket System

The B-1658 1830 mounts to a concealed wall hanger / bracket system designed to keep the mirror secured against the wall. At 18" wide, the B-1658 1830 uses Bobrick's "2S" tab design (per Bobrick's tech data sheet, the 2S tab design applies to B-1658 mirrors up to 36" width). An upper bracket engages the upper louver on the mirror's backplate, and the lower bracket is secured to the back of the mirror with double-sided tape after the mirror is pressed into final position. The result is a clean, fastener-free front face — no visible mounting hardware on the frame in a finished restroom.

Important Manufacturer Note on Tempered Glass

Per Bobrick: tempered glass mirrors resist breakage and provide a measure of safety from broken glass, but differ in color and reflective quality from standard glass mirrors. Modest distortion or heat-generated markings are normal in the tempered glass mirror manufacturing process. Bobrick will not accept returns of tempered glass mirrors with random distortion or markings. If pristine reflective quality is a higher priority for your project than impact safety, specify the standard B-165 float glass version instead.

Which Size Is Right for You?

The B-1658 1830 (18" W x 30" H) is part of the B-1658 tempered glass channel-frame series, available in two standard sizes:

• B-1658 1830 — 18" W x 30" H — this size
• B-1658 2436 — 24" W x 36" H — commonly specified size

If your project doesn't require tempered glass for safety reasons, the same channel frame with standard float glass and a 15-year silver spoilage warranty is available as the Bobrick B-165 channel-frame mirror — same frame profile, same construction, same outside-of-frame dimensions. If your project specifies a welded-frame tempered glass mirror instead of a channel frame, see the Bobrick B-2908 welded-frame tempered glass mirror.

B-1658 vs B-2908 vs B-165 — Choosing the Right Series

These three Bobrick mirror series cover different combinations of frame style and glass type:

• B-1658 channel-frame, tempered glass: Channel frame with field-replaceable glass + tempered glass for impact safety. Best for: high-traffic commercial restrooms with active maintenance programs (schools, transit, gyms).
• B-2908 welded-frame, tempered glass: Heavier Type-304 welded angle frame with satin finish + tempered glass. Does not have the same field-replaceable glass feature. Best for: institutional projects where welded-frame appearance is the higher priority.
• B-165 channel-frame, standard glass: Same channel frame as B-1658 but with No. 1 quality float glass and an explicit 15-year silver spoilage warranty. Best for: general commercial restrooms where impact safety isn't the primary concern.

Installation & ADA Compliance

Under ADA Standards §603.3, mirrors located above lavatories or countertops must be installed with the bottom edge of the reflecting surface no higher than 40" (1015 mm) above the finished floor. Mirrors not located above lavatories must be installed with the bottom edge no higher than 35" (890 mm) AFF. The B-1658 can be used in ADA-compliant restroom layouts when installed at the required mounting height — the product's suitability for accessible restroom layouts depends on proper installation height and project requirements; mounting height is the installer's responsibility.

For installation of the B-1658 1830, provide 2-7/8" (75 mm) minimum clearance above the centerline of the mounting screw holes (so the mirror can be lifted onto the wall hanger), 1" (25 mm) minimum clearance at the bottom, and 1" (25 mm) clearance on each side. Provide concealed wall backing to comply with local building codes; mounting screws are not furnished and should be selected based on the wall substrate.

Frequently Asked Questions

What are the actual dimensions of the B-1658 1830?

The Bobrick B-1658 1830 measures 18" W x 30" H (46 x 76 cm) outside-of-frame to outside-of-frame. The frame itself is a one-piece 1/2" x 1/2" x 1/2" (13 x 13 x 13 mm) Type-430 stainless steel channel with a bright-polished finish. Bobrick's stated manufacturing tolerance on framed mirrors is ± 1/8" (3.2 mm).

Is the B-1658 1830 ADA-compliant?

The B-1658 1830 can be used in ADA-compliant restroom layouts when installed at the required mounting height. ADA §603.3 requires that mirrors above lavatories be mounted with the bottom of the reflecting surface no higher than 40" (1015 mm) above the finished floor; mirrors not above lavatories no higher than 35" (890 mm) AFF. The product's suitability for accessible restroom layouts depends on proper installation height and project requirements; mounting height is set during installation.

Why specify tempered glass instead of standard mirror glass?

Tempered glass mirrors resist breakage and provide a measure of safety from broken glass, making them appropriate for environments where impact is a realistic concern. Common applications include schools, healthcare facilities, gyms, transit hubs, and any high-traffic commercial environment. Tempered glass differs in color and reflective quality from standard float glass mirrors.

Does the B-1658 have a silver spoilage warranty?

Bobrick's published B-1658 product information emphasizes the tempered glass safety properties rather than stating a specific silver spoilage warranty period — unlike the standard-glass B-165 series, which carries an explicit 15-year silver spoilage warranty. For warranty terms specific to the B-1658, refer to Bobrick's current warranty documentation or contact a Total Restroom Project Manager at 877-234-3520.

Can the glass be replaced if it breaks?

Yes — the channel-frame design is what differentiates the B-1658 from welded-frame tempered glass mirrors like the B-2908. Per Bobrick's tech data sheet, the frame screw permits replacement of the glass if the mirror is damaged. For high-traffic facilities where mirror damage is a recurring expense, this can help reduce lifetime cost compared to welded-frame mirrors that typically require full-unit replacement.

How does the B-1658 compare to the B-2908?

Both use 1/4" tempered glass. The B-1658 has a Type-430 stainless channel frame with bright-polished finish and a frame screw that permits replacement of the glass — its key cost-of-ownership advantage. The B-2908 has a Type-304 stainless welded angle frame with a satin finish; it has a more substantial architectural look but does not have the same field-replaceable glass feature. B-1658 is typically chosen where lifetime maintenance cost matters; B-2908 where welded-frame appearance is the priority.

How does the B-1658 mount to the wall?

The B-1658 1830 mounts to a concealed wall hanger / bracket system. Bobrick's "2S" tab design uses an upper bracket that engages the upper louver, with the lower bracket secured using double-sided tape after the mirror is pressed into final position. Mounting screws are not furnished and should be selected based on the wall substrate.

Are tempered glass mirror imperfections returnable?

Per Bobrick, tempered glass mirrors may show modest distortion or heat-generated markings as a normal part of the tempered glass manufacturing process. Bobrick will not accept returns of tempered glass mirrors with random distortion or markings. Buyers prioritizing pristine optical quality over impact safety should consider the B-165 standard float glass channel-frame series instead.
