Symmons at a Glance: Products and the EPD Gap

Who Symmons is and what they make

Founded in 1939, Symmons manufactures pressure‑balancing shower valves, thermostatic mixing valves, complete shower systems, touchless and metering lav faucets, and prefabricated stainless shower assemblies. The lineup spans residential and heavy‑duty commercial settings with a focus on reliability and serviceability.

Across collections like Temptrol, Ultra‑Sense, SCOT, and HydaPipe, they cover multiple plumbing categories and finishes. The active catalog appears to run to the hundreds of SKUs across faucets, valves, trims, and accessories.

Where they win in the market

Symmons shows up everywhere water has to work every time: hotels, student housing, healthcare, arenas, correctional, and facilities management. Their pitch leans on durability, easy maintenance, and a one‑valve system that takes many trims.

If you want a sustainability‑adjacent proof point from the brand itself, their water‑management platform highlights savings and leak prevention for hotels in plain language (Symmons Evolution for Hotels).

EPD coverage today

As of December 25, 2025, we could not locate any publicly available, third‑party verified Type III Environmental Product Declarations for Symmons’ flagship products on their website or major operator libraries. That does not mean they are not working on them. It does mean a specifier chasing materials credits often has to assign a conservative default, which can make a like‑for‑like swap more likely on projects that score BPDO points in LEED v5 (USGBC, 2025).

Why that matters under LEED v5

LEED v5 consolidates product disclosure and optimization and keeps EPDs as a recognized pathway inside the Materials framework. Teams are measured on transparency and optimization across product sets, so having product‑specific EPDs is still a fast way to make selection easy for architects and GCs (USGBC, 2025).

Competitors with EPDs today

Several direct and adjacent competitors already publish EPDs for high‑volume plumbing fixtures. Kohler lists 200‑plus products tagged with EPDs in its catalog in late 2025, visible by filtering their sustainability shop to “Environmental Product Declaration” results (Kohler, 2025). Sloan communicates a broad set of transparency documents and notes up to 80 sensor flushometers with EPDs, which frequently ride in the same restroom packages as valves and lav faucets on commercial jobs (Sloan, 2025). Internationally, faucet and shower‑mixer EPDs are routine, with recent examples for single lav faucets and shower thermostats in the International EPD System that US teams can reference when global brands are allowed on spec (EPD International, 2024).

A likely best‑seller without an EPD

The Temptrol pressure‑balancing shower valve is Symmons’ icon in hospitality and multifamily bathrooms. If a project owner mandates product‑specific EPDs for wet rooms, that mandate can nudge the shower package toward a thermostatic mixer from a competitor that already carries a valid declaration, even when field crews prefer Temptrol’s serviceability. This is where bids get quietly optimized away from a brand without a declaration.

Product footprint and category coverage

Symmons participates across several product categories that commonly appear in EPD scopes:

• Shower valves and trim sets used in guestroom and patient‑room bathrooms.
• Thermostatic mixing valves for tempered water distribution and point‑of‑use safety.
• Touchless and metering lavatory faucets for public restrooms.
• Prefabricated stainless shower units for high‑abuse environments.

That gives them coverage across multiple MasterFormat 22 sections. On most large projects, that means dozens of line items and potentially hundreds of install points per site.

The commercial risk of staying quiet on EPDs

When a product lacks an EPD, project teams often model it with conservative factors. That can create a documentation penalty compared to a similar product with a verified Type III EPD, especially as owners standardize embodied‑carbon tracking in product packages under LEED v5 and corporate policies (USGBC, 2025). In practice, that increases the odds of being swapped at submittals for a rival with a ready declaration.

What good looks like for first‑wave Symmons EPDs

The fast path usually starts with the core families that drive the most units and appear on most submittals:

• Guestroom shower valves and trims built on a common valve body.
• High‑volume lav faucets, including touchless variants.
• Thermostatic mixing valves used in tempered water systems.

Pick the widely used construction‑products PCR reference, align datasets to one recent production year, and roll up the steel and brass supply impacts cleanly. Then publish under a well‑recognized operator to minimize RFI ping‑pong during reviews. The teams that move quickest reduce burden on engineering by collecting plant data once, then cloning the model across sister SKUs. That approach keeps specsifying teams from hunting for missing paperwork later.

Competitors you’ll often see across bids

Expect Kohler, Moen Commercial, Delta Commercial, American Standard, Sloan, Zurn Elkay, and global players like TOTO and Grohe on the same restroom packages. Many already offer EPDs for faucets, baths, urinals, or thermostatic mixers that slot into hospitality, education, healthcare, and office use cases (Kohler, 2025) (EPD International, 2024) (Sloan, 2025).

The move that unlocks specs

Symmons’ catalog breadth and installed base give them permission to win more often. Adding product‑specific EPDs to the highest‑runner lines would remove a silent hurdle for LEED‑chasing owners and simplify the work of submittal reviewers. It is a small paperwork step with outsized impact on keeping a preferred valve from being swapped at the last minute.
