Curbless Shower Installation

A curbless shower is a design and build decision, not just an accessibility feature — a flush, step-free entry that reads as one continuous floor from the bathroom into the shower. Getting the floor to disappear like that means recessing the substrate below the surrounding slab, sloping it precisely to a linear drain, and waterproofing every plane of that recess before a single tile goes down. We plan that structural floor work from day one so the finished line stays clean.

What's included

How it works

Our curbless showers process

The right choice for homeowners who want a clean, flush shower entry with no curb to step over, and who understand that achieving it means recessing and re-sloping the floor structure, not just skipping a lip.

  1. 1

    Floor Structure & Drain Plan

    We plan the structural recess below the surrounding floor and decide on a linear or center drain, mapping the slope needed to carry water away from the open entry before any framing changes.

  2. 2

    Recess & Waterproof

    The floor is built down and sloped precisely to the drain, then fully waterproofed across the entire recessed pan — every plane of that recess is sealed before tile begins.

  3. 3

    Tile

    Large-format tile is set to keep grout lines minimal right at the transition, where the shower floor reads as a continuation of the bathroom floor rather than a separate surface.

  4. 4

    Glass & Finish

    Frameless glass panels are sized to preserve the open, continuous sightline a curbless entry is built for. We test water containment and walk the finished shower with you.

Good to know

Curbless Showers questions

Without a curb, does water actually stay in the shower?
Yes — the containment comes from the recessed, sloped floor structure and waterproofing beneath the tile, not from a curb. Done correctly, the floor carries water to the drain before it ever reaches the open entry line.
Does a curbless shower affect resale value?
A well-built curbless shower reads as a deliberate, modern design choice, and that structural floor work is part of the home's real construction rather than a surface upgrade. How it affects any given sale depends on your local market, but the build quality itself doesn't diminish over time.
Can any bathroom be converted to curbless, or does it depend on the floor?
It depends on what's beneath the existing floor and how much structural recess is available to build down into. We assess that during planning so you know upfront whether it's a straightforward recess or a more involved structural adjustment.
