What a curbless shower costs in New Hampshire

A curbless (zero-entry) shower is the single best move for a bathroom you want to stay in for decades — no lip to step over, easier to clean, and it makes a small bath feel bigger. It also costs more than a standard shower, because the work that makes it possible is hidden under the tile.

The short answer

In the Monadnock Region, budget roughly $1,500–$4,000 more for the curbless build than you would for a standard curbed tile shower of the same size. A complete curbless shower — pan, waterproofing, tile, valve and glass — typically lands in the $6,000–$14,000 range on its own, and more with a large-format stone surround or a steam unit. The spread depends almost entirely on what is under your bathroom floor.

Where the money goes

• Floor structure: the shower floor has to slope to the drain and finish flush with the bathroom floor. That means either recessing the subfloor between the joists, building up the entire bathroom floor, or using a low-profile sloped tray. The recess is the most common and the most labour.
• Drain: a linear (trough) drain along one wall lets the floor slope in a single plane, which tiles cleanly with large formats. A center point drain is cheaper but needs a four-way slope and smaller tile. Linear drains run $300–$700 for the drain alone.
• Waterproofing: a continuous membrane — sheet or liquid — across the whole floor and up the walls, bonded to the drain flange, with a required cure and a flood test before tile. On a curbless floor this is non-negotiable and it is where corners get cut on cheap jobs.
• Tile & setting: curbless floors reward large-format tile or a stone slab, set flat with an uncoupling membrane. Labour is higher than a curbed shower because the tolerances are tighter.
• Glass: a single fixed panel or a frameless door, measured after the tile is set.

What makes it cost more (or less)

A curbless shower is much cheaper to build when the bathroom is already down to the studs and joists — an addition, a gut remodel, or a slab-on-grade first floor. It gets expensive when we are working around a finished floor below, a shallow joist bay, or radiant tubing we cannot cut into. We check the structure at the consult and tell you which situation you are in before you commit.

Is it worth it?

If you plan to be in the house more than about seven years, or anyone in the household has mobility to plan for, yes — the curbless build pays for itself in resale and in not having to redo the bathroom later. If it is a rental or a short-term flip, a low-threshold (half-inch) curb gets you most of the look for less risk. See aging-in-place remodeling for the related changes worth doing at the same time.

Get a real number

Run the shower tile calculator for the material quantity, price the whole room with the bathroom budget band, then bring it to us. We build the pan, waterproof it, flood-test it and set the tile with our own crews — see custom tile showers — so there is no gap between the guy who waterproofs it and the guy who tiles it.
