Traditional Drain: Reliable and Timeless

The traditional shower drain is a circular, center-style or offset drain—typically located on the left, right, or center of the shower pan. This is the most common drain configuration found in residential and commercial showers.

Benefits of Traditional Drains:

  • Familiar and compatible with most plumbing setups

  • Available in multiple placements (left, right, or center) for design flexibility

  • Easy to install with our factory-built low profile shower pans

This classic option pairs seamlessly with both curbed showers and barrier free installations, offering a cost-effective, durable solution for most bathroom layouts.

Square Drain: Clean Look, Centered Functionality

For those wanting a more modern design, square drains offer a sleeker, architectural look while still providing central drainage performance.

Square Shower Drain Advantages:

  • Centered placement ensures even water flow

  • Aesthetic match for contemporary shower designs

  • Compatible with both curbed and roll in shower pans

  • Easier tile alignment during installation due to its geometric shape

Square drains are especially popular in ADA showers for their streamlined appearance and practical function. They're the perfect middle ground between tradition and innovation.

Trench Drain: Sleek, Seamless, and Superior Drainage

If you're looking for a luxury look with enhanced drainage, trench drains (also known as linear drains) are the ultimate upgrade.

Installed along the entry side of the shower pan, these long, smooth metal drains offer:

  • Fast, efficient water drainage

  • A nearly invisible drain line for minimalistic appeal

  • Ideal for barrier free showers and curbless showers

  • Great for wheelchair accessible showers or those needing a zero threshold entry

Our trench drains come pre-installed on select ready-to-install ADA shower pans, making installation faster and more convenient than ever.

No Wet Set Needed – Ready to Install from the Factory

Unlike traditional tiled showers that require time-consuming and messy wet set mortar bases, our shower pans arrive ready to install straight from the factory. That means:

  • No need to wait for curing time

  • Reduced labor costs

  • Consistent slope to drain every time

  • Fully sealed and leak-resistant from day one

Whether you're outfitting a senior’s home, remodeling a hospital wing, or upgrading an assisted living facility, our pre-sloped, pre-leveled shower bases make your job faster and easier.

Threshold Options: Curbed or Barrier-Free

Choosing the right threshold style is critical, especially when meeting ADA compliance or creating a wheelchair accessible shower.

Barrier-Free Thresholds

  • Entry heights as low as 0.5" for ADA-compliant roll in showers

  • Option for beveled edge for smoother transitions with wheelchairs or walkers

  • Perfect for senior living, rehab centers, and in-home aging-in-place renovations

Curbed Thresholds

  • More traditional appearance with 90-degree edge

  • Offers water containment for non-ADA installations

  • Available in multiple curb heights depending on need and layout

Whether you’re looking for a true ADA shower or simply want a modern low profile shower pan, we’ve got options that balance form and function.
