Zurn Z451B – 2" Shallow Trap Drain with Adjustable Strainer

A compact shallow-trap floor/shower drain engineered for tight floor builds. The Z451B pairs a 2" trapped body with an adjustable strainer to align perfectly with finished floors—ideal for restrooms, showers, balconies, and retrofits where depth is limited.

In technical terms, the Z451B integrates a shallow water-seal trap to resist sewer gas and a height-adjustable strainer assembly for clean transitions to tile or resinous finishes. In plain English: it’s a space-saving drain that controls odors and finishes beautifully, even in thin toppings.

Frequently Asked Questions

What does “shallow trap” mean?
It’s a low-profile water seal built into the drain body, helping resist sewer gas while fitting thin floor assemblies found in renovations and balconies.
How does the adjustable strainer help?
It lets installers fine-tune height so the top sits flush with tile or coatings—reducing trip edges and punch-list touchups.
Any tips for maintenance?
Establish a regular cleaning cadence for hair, sand, and debris. Periodic water priming helps maintain the shallow water seal in low-use areas.
