Division 22 plumbing specialties is the finishes division with the most direct dependency on the licensed plumbing subcontractor’s work. The trim kits that Division 22 supplies must be compatible with the rough-in valves that the licensed plumbing sub installed during rough plumbing, months before the finishes phase begins. If trim kit and valve compatibility is not confirmed before the rough plumbing phase, the discovery of incompatibility at trim-out requires either a product substitution or a rough-in correction, both of which add cost and time to the project.
Trim kit and valve compatibility
Plumbing fixture trim kits are manufacturer and model-specific. A Delta Monitor trim kit fits only the Delta Monitor rough-in valve. A Moen Posi-Temp trim kit fits only the Moen Posi-Temp rough-in valve. Cross-brand compatibility does not exist at the trim kit level, and even within a single manufacturer, trim kits are series-specific and may not be interchangeable between product lines.
The most reliable approach to trim kit and valve compatibility is to specify the complete fixture package, including rough-in valve and trim kit, from the same manufacturer and product family, confirmed with the licensed plumbing sub before rough-in begins. When the rough-in valve and trim kit are both part of the same manufacturer’s specified package, compatibility is confirmed at specification.
When the rough-in valve is specified by the licensed plumbing sub independently of the trim kit, the Division 22 sub must obtain the exact valve manufacturer, model number, and series from the licensed plumbing sub before ordering any trim kit. A trim kit ordered from a manufacturer’s product catalog without confirming the specific valve model in the wall may not fit.
Fixture grade selection by unit type
Plumbing fixture trim kits come in three broad grade categories for multifamily construction.
Production grade fixtures are manufactured for high-volume residential construction, offer limited finish options, and are typically available from regional plumbing supply houses within one to two weeks. Production grade is appropriate for workforce and Class B multifamily where the fixture aesthetic is secondary to function and durability.
Mid-grade fixtures offer expanded finish options including matte black, brushed gold, and spot-resistant finishes, provide better flow rates and valve feel than production grade, and are the appropriate specification for Class B to Class A multifamily. Mid-grade fixtures coordinate more effectively with the premium hardware finish packages specified at the Class B and Class A tier.
Premium grade fixtures from manufacturers including Kohler, Moen’s premium lines, Delta’s premium collections, and specialty brands provide the design statement appropriate for Class A luxury multifamily. Premium fixtures have longer lead times, typically three to six weeks, and higher material costs, but their visual quality differentiates Class A units in ways that leasing teams can point to during tours.
Sink cutout template coordination
As covered in the Division 22 supply depth article, the sink cutout template must be provided to the countertop fabricator before fabrication begins. The sink model must be confirmed before countertop fabrication so the cutout dimensions in the template match the sink being installed.
A sink model change after countertop fabrication requires re-fabrication if the new sink’s cutout dimensions differ from the fabricated cutout. Confirm the sink model as a locked specification before countertop fabrication begins and treat any sink model change as a change order that triggers a countertop re-fabrication evaluation.
Lead time management for specialty fixtures
Standard production plumbing fixtures are available within one to two weeks from regional supply houses in most western US markets. Specialty fixtures, including premium brands, matte black finish options, and non-standard configurations, may have lead times of four to eight weeks. Confirm lead times for all non-standard fixtures before finalizing the project schedule.
How Innergy manages Division 22
Innergy confirms trim kit and valve compatibility with the licensed plumbing sub before any fixture is ordered, provides the sink cutout template to the countertop fabricator, establishes fixture lock dates with the developer at pre-construction, and confirms lead times for specialty fixtures before finalizing the procurement timeline.

Garbage disposal supply scope
Garbage disposals are a Division 22 plumbing specialties item in multifamily projects where the developer specifies disposal installation. The disposal model must be confirmed against the sink configuration, because some single-bowl sink configurations have disposal space limitations and some double-bowl sinks require a specific disposal mounting configuration.
Garbage disposals in multifamily construction are typically supplied by the fixture supply sub and installed by the licensed plumbing sub. The scope boundary between supply and installation must be confirmed explicitly in both the Division 22 subcontract and the licensed plumbing subcontract to prevent a gap or double-assignment of the installation scope.
Shower valve and trim coordination depth
The shower valve and trim kit coordination described in the main Division 22 article is the most time-sensitive coordination in the division because the rough-in valve is installed months before the trim kit, and discovering incompatibility at trim-out requires either a valve replacement or a trim kit substitution. Both corrections are expensive and time-consuming.
For projects where the developer has specified a specific finish aesthetic, such as matte black, that requires coordinating a specific trim kit with a compatible rough-in valve, confirm the valve and trim kit compatibility with the manufacturer’s product compatibility documentation before the rough plumbing phase begins. A matte black trim kit that requires a specific valve series must be specified to the licensed plumbing sub before they purchase the rough-in valves.

Innergy covers Division 22-Plumbing Specialties for multifamily construction under a single subcontract.
Division 22 plumbing specialties is the finishes division most vulnerable to the specification gap between what the licensed plumbing sub installed at rough-in and what the finishes sub is planning to deliver at trim-out. Closing that gap requires trim kit and valve compatibility confirmation before any fixture is ordered, and it requires it early enough that a compatibility problem can be resolved before the rough-in phase is complete. Innergy’s Division 22 process makes this confirmation a pre-procurement deliverable on every project.
