1/4" per foot minimum
Floor slope
The shower floor must fall consistently toward the drain without creating a lip at the entry. That slope is planned below the tile, not corrected with grout.

Walk-In & Curbless Showers — Zero Threshold. Zero Compromise.
Curbless showers require precise floor slope and waterproofing — most contractors get it wrong. We get it right.

The technical standard
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.
Drainage designed into the layout
Linear drain placement
A linear drain at the wall or shower edge can simplify the floor plane and keep water moving where it belongs. Placement is set before framing and tile.
One sealed system
Waterproofing membrane continuity
The floor membrane must connect continuously to the walls, drain flange, niches, and every penetration. Tile is not the waterproofing layer.
Choose the right format

Built for real life
Who Benefits From a Curbless Shower?
Aging in place
Step-free access helps keep a bathroom practical as needs change, without making it look institutional.
Mobility concerns
A continuous floor removes the tripping point at a traditional shower curb and supports easier entry.
Modern design preference
Clean floor lines and open sightlines make the room feel larger, quieter, and more deliberate.
Easier cleaning
Fewer ledges, less trapped grime, and a floor that drains correctly make routine cleaning simpler.

Our installation sequence
How We Build a Curbless Shower
01
Assess the existing structure
We inspect floor framing, drain location, plumbing, and surrounding conditions before a scope is set.
02
Plan the recess and drainage
We establish the finished floor elevations, required slope, and drain location before the shower pan is built.
03
Build and test the waterproof system
Membranes, seams, drain connections, and penetrations are completed as one system and tested before tile.
04
Set finishes and complete the walkthrough
Tile, glass, fixtures, and transitions are installed over the verified system, then reviewed with you at completion.

Walk-In & Curbless Shower FAQs
How much does a curbless shower cost?
A curbless shower typically starts around $18,000 and increases with the amount of structural work, drain relocation, tile selection, glass, and accessibility features. We price from the actual conditions in your home, not a generic allowance.
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.
