SereneDrains 39" Offset Outlet Linear Shower Drain – Side Outlet for Off-Center Plumbing, Floor Joists & Concrete Slabs

39 Inch Offset Outlet Linear Drain: The Solution for Off-Center Plumbing, Floor Joists & Concrete Slabs

When your shower drain won't line up with the plumbing, this is the fix.

You cut into the floor and find a floor joist directly where the drain needs to go. The existing plumbing is off-center. Or you're working over a concrete slab where the drain rough-in was installed years ago, and moving it means breaking concrete, relocating plumbing, or creating a much bigger remodeling job.

The SereneDrains 39" Offset Outlet Linear Shower Drain is designed for these challenging installations. Its 2" offset outlet is positioned 2.8" from the drain end, giving you more flexibility when the shower drain can't connect directly to a centered waste line. Instead of forcing the plumbing to match a conventional center-outlet drain, you can plan the shower drain around the existing rough-in, floor framing, or slab conditions.

As an offset outlet linear drain, the 39" size fits any shower layout and works well for larger shower footprints. Other lengths are available if you need something shorter or longer, see the sizes below.

Designed for Off-Center Plumbing

A centered shower drain isn't always possible. This 39" offset outlet linear drain is built to work around:

• Off-center shower drain plumbing
• Existing drain rough-ins
• Floor joists beneath the shower
• Concrete slab plumbing
• Existing side-positioned plumbing
• Shower remodel constraints
• Projects where relocating the drain would mean unnecessary demolition

Important: If a floor joist is directly beneath the desired drain location, always follow applicable structural requirements and consult a qualified professional before cutting, drilling, or modifying framing.

2" Offset Side Outlet Linear Drain, Built for Installation Flexibility

The 2" outlet is positioned 2.8" from the drain end rather than centered in the middle of the channel. This offset configuration can give installers more flexibility when the shower waste line doesn't line up with a conventional center-outlet drain, helping the layout work with existing plumbing conditions rather than requiring relocation. If your plumbing is already centered, SereneDrains also offers standard center outlet linear drains: shop center outlet linear drains.

Always verify your existing rough-in dimensions before ordering.

Ideal for Remodels & Concrete Slabs

Moving a shower drain during a remodel can mean breaking concrete, opening floors, or reworking structural framing. If your existing plumbing is positioned within the offset outlet's workable range, this configuration may allow you to use the existing rough-in without relocating the drain line or cutting into the slab. Well suited for:

• Bathroom and shower remodels
• Concrete slab installations
• Slab-on-grade construction
• New builds with plumbing restrictions
• Curbless showers
• Walk-in showers
• Barrier-free, wheelchair-accessible showers

Built to Last

16-gauge 304 stainless steel drain channel with a brushed stainless steel finish and electropolished surface treatment. Fully welded and leak-tested before it ships, built for use in residential showers and other wet areas. No special cleaning is required for everyday maintenance.

Pre-Sloped for Efficient Drainage

The channel is pre-sloped toward the outlet for consistent water flow. Approximate flow rates:

• 6.3 GPM when installed at the shower entrance
• Up to 9.5 GPM when installed against the wall

Actual performance varies with slope, grate style, and installation conditions. Intake area is approximately 19.39 sq. in. for the 39" size.

Choose Your Grate Design

• Tile Insert – install matching tile into the grate for a seamless, integrated floor look
• Ocean Wave – decorative flowing wave pattern for a spa-like feel
• Square – classic square-pattern grid, clean and modern
• Broken Lane – staggered contemporary pattern

Easier Tile Installation

The linear channel design has straight edges that are easier to measure and cut around than a round drain. It's built to align with common tile sizes, helping reduce complicated cuts and tile waste. With the Tile Insert grate, matching floor tile sits inside the grate itself for a low-profile, integrated look with a minimal grout rim.

Before You Order

Because this is an offset outlet linear shower drain, verify your existing plumbing location before ordering. The 2" outlet center is positioned 2.8" from the drain end. Measure your existing rough-in and available shower space to confirm the outlet location works for your installation.
