Division 22 plumbing fixture supply on a multifamily project covers procurement, delivery, and site logistics for the fixtures that the licensed plumbing sub installs and connects. The scope includes kitchen and bath sinks, shower pans, tub surrounds, and the faucet trim kits, showerhead trim kits, and accessory trim kits that complete the plumbing fixture package for each unit type.
The value of having Division 22 under the same subcontract as the other interior finishes scopes is coordination. When fixture supply is a separate procurement from the countertop scope, the sink cutout in the countertop must be coordinated against the sink dimensions from a separate sub’s order. When fixture supply is separate from the cabinet scope, the base cabinet dimensions and the sink undermount depth must be coordinated between two subs who are not in regular communication. When one sub covers both, these dimensions are coordinated internally.
What Division 22 supply scope covers on a multifamily project
Kitchen sinks. Undermount and drop-in sinks supplied to match the countertop specification and the cabinet base dimension. Sink cutout dimensions are confirmed against the countertop fabricator before countertop production begins, and the sink is supplied to the floor in time for the countertop installation crew to set it during countertop installation. The plumbing sub makes the final connection to the faucet supply lines and drain.
Bath sinks and vanity bowls. Undermount and drop-in sinks for bath vanities, supplied in the finish and configuration specified by the unit type matrix. Vessel sinks, where specified, require confirmation that the vanity cabinet is designed to accommodate the vessel height above the countertop surface. This is a pre-procurement coordination item between the Division 6 cabinet scope and Division 22.
Shower pans. Acrylic and composite shower pans in standard and custom dimensions, supplied ahead of tile or shower surround installation. Shower pan dimensions must be confirmed against the rough plumbing drain location before procurement. A shower pan that arrives to the job site and does not align with the drain location cannot be installed correctly. The Division 22 sub should provide shower pan dimensions to the GC before the rough plumbing sub establishes the drain location.
Tub surrounds. Acrylic and composite wall surround systems for tub-shower combinations where tile is not specified. Tub surrounds install after the tub is set and after the rough plumbing is confirmed final at the shower valve and showerhead locations. The surround panels are cut at the job site to fit around the plumbing penetrations. Confirm that the penetration locations are final before the surround panels are cut.
Faucet and showerhead trim kits. Kitchen faucets, bath faucets, showerhead trim kits, and tub spout trim kits supplied in the finish and configuration specified by the unit type matrix. Trim kit finishes must coordinate with the Division 6 cabinet hardware finish and the Division 10 toilet accessory finish. Confirm the hardware finish specification before procurement.
The coordination requirement between Division 22 and the licensed plumbing sub
The licensed plumbing sub on a multifamily project is responsible for rough plumbing, drain locations, vent connections, and final connections of the fixtures. The Division 22 supply sub provides the fixtures and trim kits; the licensed plumbing sub makes the connections. These two scopes must be coordinated before procurement begins.
Trim kit compatibility. Faucet and showerhead trim kits are specific to the valve body that the plumbing sub installs during rough plumbing. A trim kit from Moen will not fit a Kohler valve body. Before the Division 22 sub places any trim kit orders, confirm the valve brand and model that the licensed plumbing sub is installing for each application: kitchen faucet, bath faucet, shower valve, and tub spout. Ordering trim kits without this confirmation is a common source of incompatibility problems discovered at installation.
Delivery timing. The licensed plumbing sub needs fixtures on site before they can trim out. If fixture delivery is late, plumbing trim-out is late, and the floor completion milestone is late. Confirm the delivery date at the time of order placement and communicate it to the plumbing sub and the superintendent so trim-out can be planned.
Sink cutout dimensions. The countertop fabricator needs the sink model number and the sink cutout template before fabricating countertops. If the Division 22 sub does not provide this information before countertop fabrication begins, the countertop is fabricated without a cutout, and a field modification is required. Confirm that the sink model is selected and the cutout dimensions are provided to the countertop sub before fabrication begins.
Shower pan sequencing and rough plumbing
Shower pan installation is the first step in the wet area finish sequence, before tile or surround installation. The shower pan must be set and leveled before any wet area finish work begins on that shower. The shower pan drain must align with the rough plumbing drain location; if it does not, either the pan or the drain must be modified.
Confirm the rough plumbing drain location before ordering the shower pan. On projects where the rough plumbing is already set before the Division 22 sub is engaged, the existing drain location governs the pan selection. On projects where the Division 22 sub is engaged before rough plumbing is set, the pan dimensions should govern the drain location.
How fixture finish consistency affects the unit
Finish consistency across plumbing fixture trim kits, cabinet hardware, and toilet accessories creates a unit that reads as intentionally designed. Finish inconsistency creates a unit that reads as assembled from whatever was available. On Class A multifamily projects where the developer is competing on design quality, finish inconsistency is a deficiency that the developer will require correction.
The Division 22 sub should receive the hardware finish specification from the GC before procurement. On full-package Innergy projects where Division 6, 10, and 22 are all our scope, this coordination is internal. On projects where these scopes are separated across different subcontractors, the GC must distribute the hardware finish specification to all three subs and confirm that each is ordering to the same finish.
How Innergy handles Division 22 on multifamily projects
Innergy covers plumbing fixture supply on multifamily projects as part of our Division 22 scope. We confirm shower pan dimensions against the rough plumbing drain location before procurement, provide sink cutout dimensions to the countertop fabricator before fabrication begins, confirm trim kit brand and model compatibility with the licensed plumbing sub before ordering, and coordinate delivery timing against the plumbing sub’s trim-out schedule. For Division 22 fixture supply as a standalone scope or as part of a full seven-division interior finishes package in TX, WA, OR, CO, UT, or NM, contact us and we respond within one business day.
