1/4" per foot — planned below the tile
Precise floor slope
The shower floor falls consistently toward the drain without creating a lip at the entry. That slope is engineered into the substrate, not corrected with grout.

Built right from the floor up
What makes a curbless shower work
A zero-threshold shower is not a standard shower with the curb removed. The floor, drain, membrane, and surrounding room have to work as one system — planned before a single tile goes up.
Drainage designed into the layout
Linear drain placement
A linear drain at the wall or shower edge simplifies the floor plane and keeps water moving where it belongs. Placement is confirmed before framing and tile begin.
One sealed system — floor to wall
Continuous waterproofing
The membrane connects floor to walls, drain flange, niches, and every penetration. Tile is the finish. The membrane is the protection. We never confuse the two.
Design options
Choose the format that fits your bathroom
From $18,000Classic walk-in
A dedicated zero-threshold shower with a controlled entry, tiled floor, and frameless glass selected for the room's layout. The most popular format for master and primary bathrooms.
From $30,000Wet room
A fully waterproofed bathing zone where the shower area and surrounding floor drain as one coordinated surface. A statement design for larger bathrooms.
From $25,000Barrier-free ADA
A mobility-focused shower with proper clearances, support blocking, accessible controls, and drainage that performs without a curb. Designed for aging in place.
Built for real life
Who gets the most from a curbless shower
Modern design
Clean floor lines, open sightlines, and seamless tile make the room feel larger, quieter, and more deliberate. No curb means nothing interrupts the visual flow.
Aging in place
Step-free access keeps a bathroom practical as needs change — without making it look institutional. The design works for today and for years from now.
Easier cleaning
Fewer ledges, less trapped grime, and a floor that drains correctly make routine cleaning faster. No curb means no scrubbing a hard-to-reach edge.
Comfort & openness
A walk-in shower with frameless glass and a seamless floor feels more spacious than the footprint suggests. The open entry makes the whole bathroom feel bigger.

Our curbless shower installation sequence
01
Assess the existing structure
We inspect floor framing, drain location, plumbing, and surrounding conditions before a scope is set. No surprises mid-project.
02
Plan the recess and drainage
We establish finished floor elevations, required slope, and drain location before the shower pan is built. The geometry is confirmed on paper first.
03
Build and test the waterproof system
Membranes, seams, drain connections, and penetrations are completed as one system and tested before tile goes up.
04
Set finishes and complete the walkthrough
Tile, glass, fixtures, and transitions are installed over the verified system, then reviewed with you at completion.

Curbless shower FAQ
How much does a curbless shower cost?
Our curbless showers start at $18,000. Final cost depends on the amount of structural work required, drain relocation, tile selection, glass configuration, and accessibility features. We provide a written estimate after inspecting your bathroom.
What makes a curbless shower different from a standard shower?
A curbless shower requires a recessed floor, precise slope toward the drain, and a continuous waterproofing system that connects the floor, walls, and drain as one unit. You can't simply remove the curb from a standard shower — the floor structure has to be built for it.
Does a curbless shower need a 1/4-inch-per-foot slope?
Yes. The shower floor needs a consistent minimum slope of 1/4 inch per foot toward the drain. The challenge is creating that slope while keeping the entry truly zero threshold and the surrounding floor level where it needs to be.
What drain options work for a zero-threshold shower?
Center drains, point drains, and linear drains can all work when they are planned with the floor geometry. Linear drains are often useful for a single-plane slope, but the right choice depends on the room and plumbing.
How is a curbless shower waterproofed?
We treat the shower as a continuous waterproofing system: floor, walls, drain connection, seams, niches, and penetrations. Tile and grout are finishes — the membrane behind them protects the structure.
What glass options work with a walk-in shower?
Depending on the layout, a walk-in shower can use a fixed glass panel, a partial enclosure, a door-and-panel configuration, or no glass at all in a larger wet-room design. We select glass after the drainage and entry path are resolved.
Are curbless showers easier to clean?
They can be. A properly sloped floor moves water to the drain, and the absence of a curb removes one of the hardest edges to clean. Tile selection and glass layout also affect ongoing maintenance.
Is a curbless shower good for aging in place?
Yes. A zero-threshold entry reduces the step into the shower and can be coordinated with grab-bar blocking, a bench, accessible controls, and appropriate clearances. We design the full system around how it will be used.
Can any bathroom have a barrier-free shower?
Many can, but the existing floor framing, drain height, plumbing route, and room layout determine what is required. We assess those conditions first and explain the structural work needed before we recommend a design.
