Bathroom Remodeling in Frederick & Central MD
A walk-in shower built from the structure outwards, not assembled from a kit. Framing corrected, the wet area waterproofed as a system, and the glass planned before the first tile goes on.
Quick answer
A standard alcove shower, tiled and built in place, runs $8,000 to $15,000. A larger walk-in with a frameless glass panel runs $12,000 to $24,000, and a curbless build sits above that because the floor structure has to be opened. Those figures are construction and tile; the glass is listed separately because it is ordered after the tile is finished.
The work
There are two ways to put in a walk-in shower. One is to drop in a moulded pan and a surround, which is quick, costs less and looks exactly like what it is. The other is to build the shower as part of the house — framed, waterproofed, tiled and glazed to the room it sits in. This page is about the second one.
Most of the decisions that determine whether it works happen before anything is visible. Whether the walls are plumb enough for large-format tile. Whether the floor has fall across the whole pan rather than just near the drain. Whether there is blocking behind the plasterboard where the glass channel will land, or whether the installer is going to be screwing into nothing.
The glass is the clearest example. Frameless panels are cut to a measurement taken off the finished walls, with no tolerance to hide behind. If the walls are out, the gaps show, and nobody can fix that at the glass stage. We correct the framing first and measure the glass afterwards, which is the only order that works.
Maryland walk-in showers, built in place. Tile selection and glass specification move these numbers more than the construction does.

What’s included
Written into the estimate, not assumed. If something on your job is not on this list, it gets priced and named before anyone starts.
Walls brought plumb and flat before anything closes up, because large-format tile and frameless glass both read every error in the structure behind them.
Solid timber set behind the board wherever a glass channel, hinge, shelf or shower arm will eventually be fixed, which is a five-minute job at the right stage and impossible later.
The floor formed so water runs to the drain from every point of the pan, not just the half nearest it. Standing water at a corner is a build fault, not a maintenance problem.
Membrane, corners, drain flange and curb detailed as a single continuous assembly by one crew, so there is no joint between two trades at the point where water actually sits.
Recesses formed in the wall cavity and sloped to drain, and any seat built into the structure rather than tiled over a bracket.
The panel is templated after the tile is on and set, never off a drawing, so the gap down the edge is even and the door closes against something square.

Straight answers
Not covered here? Call and ask — you’ll get a real answer, not a “depends on the job”.
If the budget is tight and the bathroom is a rental or a secondary bath, a quality acrylic pan and surround is a sensible, honest choice and we will fit one. In a primary bathroom you intend to keep, a built shower is the better purchase: it fits the actual room, there is no fixed size to design around, and it can be repaired in sections rather than replaced whole.
Yes, and this is the most common reason a tiled shower looks wrong. A 12 by 24 inch tile spans far enough to bridge a hollow in the wall, so one end stands proud of its neighbour and the grout line steps. Small tiles follow a wavy wall and hide it. If you want large format, the framing has to be corrected first, and we price that rather than hoping.
Two to three weeks for a standard alcove, three to four for a large or curbless build, plus roughly a week after that for the glass to be templated, made and fitted. The glass lead time is outside our control and we will tell you what it is at the time rather than averaging it.
Same crew, same visit
Most bathroom remodeling jobs are two or three of these at once, which is why they are priced and scheduled together rather than as separate call-outs.
