Replacing a bathtub you never use with a walk-in shower is one of the most popular bathroom projects in Maryland, especially for homeowners planning to stay in their house as they get older. Here is what a tub to shower conversion costs, what makes one project cost three times another, and how to choose between a prefab shower and a custom tiled one.
Key takeaways
- National data from HomeAdvisor shows most conversions between $1,500 and $8,000, and custom tiled walk-in showers from about $3,500 to $15,000.
- Tile, glass and moving the drain are the biggest cost drivers.
- Hidden water damage behind old tub walls is common in older homes; budget a contingency.
- Accessibility features like a bench, grab bars and a low curb add little cost when planned up front.
Tub to shower conversion cost ranges
| Type of conversion | National planning range (HomeAdvisor) | Good for |
|---|---|---|
| Prefab acrylic or fiberglass shower kit | $1,000 to $8,000 installed | Budget projects, rentals, fast turnaround |
| Solid surface or cultured marble wall panels | Mid range | Low maintenance, few grout lines |
| Custom tiled walk-in shower | $3,500 to $15,000 | Primary baths, design flexibility |
| Curbless or barrier free shower | Upper end or above | Aging in place, wheelchair access |
In Maryland, labor, permit requirements and the age of many homes push real projects toward the middle or upper end of these national ranges. Your estimate depends on the details below.
What affects the price
Shower base
A prefabricated pan is fastest and least expensive. A tiled mortar bed or a linear drain system costs more but allows any size, a curbless entry and a custom look.
Walls
Acrylic panels install in a day. Tile requires a waterproofing system, setting time and grout, so it takes longer and costs more, but it is the look most homeowners want.
Plumbing changes
A tub drain is usually in a different spot than a shower drain needs to be, and the valve often moves higher. Moving the drain on a slab or in a joist bay adds cost. Upgrading to a pressure balanced or thermostatic valve is a smart time to do it.
Glass
A curtain costs almost nothing. Framed doors are moderate. Frameless glass panels and doors are the premium option and need a measurement after the tile is done.
Hidden damage
Old tubs often hide rotted subfloor, mold or failed backer board. Ask your contractor how unforeseen conditions are priced before you sign.

Make it safe for every age
- Install blocking in the walls for grab bars, even if you do not want bars yet.
- Choose a low curb or curbless entry.
- Add a fold down or built in bench.
- Use a hand shower on a slide bar.
- Pick small format or textured tile on the floor for grip.
These features are the core of the universal design bathroom in the Cost vs. Value report, which recouped about 61 percent of its cost at resale in the South Atlantic region in 2025.
Will removing the tub hurt resale?
Many buyers with young children want at least one bathtub in the house. If you are converting the only tub, think about who will buy your house. Converting the tub in a primary bathroom while keeping one in a hall bath is the safest choice.
How long does a conversion take?
A prefab conversion can be done in two to four days. A custom tiled shower usually takes one to two weeks, including waterproofing cure time, tile, grout and glass measurement and installation.
