Gerber

Gerber makes plumbing fixtures for contractors who need reliability and performance specs they can count on. Founded in 1932 specializing in plumbing fixtures, this isn’t some flashy brand chasing homeowner trends. They focus on quality craftsmanship, utilizing brass for their faucet bodies and waterways to ensure longevity. Designed with professionals in mind, Gerber emphasizes performance, ease of installation, and long-term durability.

Maxwell ADA Toilet - Built for Accessibility and Performance

The Maxwell ADA (MX-21-928) delivers on the two things that matter most in commercial bathrooms: accessibility compliance and clog-free operation. The 16.5-inch ErgoHeight bowl meets ADA requirements while giving you a 2-inch fully glazed trapway and 3-inch flush valve for maximum flow.

SpecificationValue
Bowl Height16.5” (ErgoHeight™)

Trapway2” fully glazed
Flush Valve3”
Water UseDual-flush 1.28/1.6 gpf
Weight51-53 lbs (bowl only)
Water Surface7-3/8” x 8-7/8”

That 3-inch flush valve isn’t just a number on a spec sheet. Combined with the dual-fed siphon jet and front jet flushing action, it moves waste reliably without the double-flushing that kills water efficiency numbers. The dual-flush option lets facilities meet conservation goals without sacrificing performance.

Suitable for public restrooms, healthcare facilities, and assisted-living environments. Fully ADA compliant for use in accessible restrooms. The tool-free installation when paired with tank saves labor time on multi-unit projects.

Replacement Parts That Actually Fit

The 88861 shower diverter shows Gerber understands what drives service plumbers crazy: replacement parts that almost fit. This single-knob diverter gets the details right with 2-3/8 inch diameter x 2-1/2 inch height dimensions and zinc/metal construction with chrome plating.

Direct replacement for original Gerber tub/shower diverter handles — it’ll work with their single-handle tub and shower valves without modification.

The Bottom Line on Gerber

Known for its professional-grade performance, Gerber emphasizes durability, water efficiency, and innovative design, partnering with programs like EPA WaterSense to promote water conservation. They’re not trying to win design awards or impress showroom browsers. Known for durable, water-efficient products like the Avalanche, Viper, and Maxwell series, which are trusted by professionals for their performance and reliability. Customer reviews highlight the durability, powerful flushing performance, and comfort of Gerber toilets.

For Montana contractors dealing with hard water, temperature swings, and commercial bathroom demands, Gerber delivers products built to last through actual use, not just warranty periods. Their focus on brass internals, oversized flush valves, and multi-fit replacement parts shows they understand what matters when you’re billing by the hour and callbacks eat into profit.

Skip them if you’re chasing the lowest bid on a tract home project. But for commercial work where ADA compliance and long-term reliability matter more than saving twenty bucks on a toilet, Gerber’s professional focus earns its place on the spec sheet.
