Walk-In Shower Cost Calculator: Prices by Type, Size, and Tub Conversion for 2027

A walk-in shower can cost under $3,000 for a prefab kit in an existing shower space, or more than $15,000 for a large custom-tiled, curbless design. Use the calculator below to estimate your project, then read on for prices by shower type and size, the costs people often miss, and ways to save.

Walk-in shower cost at a glance

Heading into 2027, most homeowners pay about $3,000 to $11,000 for a walk-in shower. The biggest factors are whether you’re converting a tub or replacing a shower, the wall and base system you choose, the glass, and local labor rates. A typical tub-to-shower conversion with porcelain tile and semi-frameless glass runs about $5,300 to $10,600.

Walk-in shower cost by type

These ranges include demolition, plumbing, the shower system, glass, standard fixtures, and a permit, at national average prices.

Prefab acrylic or fiberglass kits

Prefab kits include a base and wall surround, often with molded shelves or a seat. They are the cheapest and fastest option, usually installed in a day or two, and have no grout to clean. The trade-off is limited sizes and a less custom look. One-piece units may not fit through doors in an existing home, so remodels usually use three- or five-piece kits.

Solid-surface and stone-resin wall panels

Large wall panels made of solid surface, cultured stone, or stone resin go up quickly over a new base and give a seamless, grout-free finish that looks more upscale than a basic kit. Bath remodeling franchises often use this approach. Compare their quotes carefully; our Bath Fitter vs. Re-Bath vs. Jacuzzi comparison breaks down how those companies price their work.

Tiled showers

A tiled shower is built on site with a waterproofed pan, backer board or foam board, and a waterproof membrane, then finished with tile. It can be any size or shape and can include niches, benches, and custom layouts. Ceramic and porcelain are the most common choices. Natural stone and large-format tile cost more for the material and for skilled installation.

Curbless showers

A curbless shower has no step at the entry, which makes it easier to use for anyone with limited mobility and gives the bathroom an open, modern look. The floor must be recessed or built up so water drains properly, and a linear drain is often used. That structural work adds $1,500 to $3,500 compared with a standard tiled shower.

Walk-in shower cost by size

Size affects tile and glass costs most. These ranges are for replacing an existing shower with porcelain tile and semi-frameless glass.

Most building codes require a shower to be at least 30 × 30 inches. A 36 × 48-inch or larger shower feels much roomier, and a 60-inch shower fits neatly into the space left by a standard bathtub.

Tub-to-shower conversions

Replacing a bathtub with a walk-in shower is one of the most popular bathroom upgrades. It usually costs more than replacing an existing shower because the tub has to be removed, the drain often has to move to a new position and size, and a shower pan must be built. A new shower valve is usually needed at the right height too. For a closer look at conversions, including one-day systems and DIY kits, use our tub to shower conversion cost calculator.

Before you remove the only tub in your home, think about resale. Many buyers with young children want at least one bathtub. Our guide to walk-in shower vs. tub costs covers the trade-offs, and if you need a tub for accessibility, see our walk-in tub cost calculator.

What affects walk-in shower cost

Glass doors and enclosures

Glass can be one of the biggest single costs. A framed door usually costs $500 to $900 installed, semi-frameless glass $800 to $1,500, and a frameless door with a fixed panel $1,500 to $3,000 or more for large showers. A curtain or an open, doorless entry costs the least. Our shower door cost calculator goes into more detail.

Valves and shower heads

A standard pressure-balancing valve with a single head is the baseline. A rain head paired with a handheld adds convenience and costs more in both parts and plumbing labor. Thermostatic valves with body sprays need more supply lines and can cost $1,500 or more.

Plumbing changes

Keeping the drain and valve in roughly the same spot saves money. Moving them, or putting a shower where there wasn’t one before, means opening floors and walls for new drain and supply lines. A shower in a new location can add $2,000 to $4,500 in plumbing alone.

Niches, benches, and accessibility features

A recessed niche adds built-in storage for about $200 to $500. A tiled bench adds $400 to $1,200, while a fold-down seat costs less. Grab bars should be anchored into blocking or studs, and adding blocking during construction is much cheaper than retrofitting it later.

Permits and your location

Most towns require a plumbing permit when you replace a shower valve or move a drain, typically $150 to $500. Labor rates vary widely by region, with high-cost areas such as California, New York, and Massachusetts running 15% to 25% above the national average. The calculator adjusts for your state.

Hidden costs to plan for

• Water damage and rot: Old tubs and showers often hide leaks that have damaged the subfloor or framing. Repairs can range from a few hundred dollars to several thousand.
• Mold: If mold is found behind walls, professional remediation may be needed before the new shower goes in.
• Outdated plumbing: Old galvanized supply lines or a corroded drain may need replacing once the walls are open.
• Asbestos: Homes built before about 1980 may have asbestos in old flooring, adhesives, or wall materials. Have suspect materials tested before demolition.
• Ventilation: A larger shower creates more humidity. If your bathroom fan is weak or vents into the attic, plan to upgrade it.

Set aside 10% to 15% of your budget for surprises like these, especially in an older home.

Ways to save on a walk-in shower

• Keep the drain where it is. Using the existing drain location avoids the biggest plumbing costs.
• Choose a prefab base with tiled walls. A factory-made base removes the cost of a custom mortar pan while still allowing a tiled look.
• Use standard-size porcelain tile and save natural stone for an accent wall or niche.
• Pick semi-frameless glass instead of fully frameless, or use a curtain or doorless entry.
• Do the demolition yourself if you can do it safely. Removing an old tub or surround can save several hundred dollars.
• Get three written quotes and confirm each includes waterproofing, glass, fixtures, and permits.
• Schedule during slower months. Some contractors are more flexible on price and timing in late fall and winter.

How to compare contractor quotes

Get at least three detailed, written quotes. A good quote lists the shower system and waterproofing method, tile or panel selection, glass, valve and fixtures, demolition, plumbing work, permits, and a timeline. Watch out for these red flags:

• A price far below the others, which can signal missing insurance, skipped waterproofing, or a scope that leaves things out
• A large upfront deposit before any work begins
• Vague descriptions such as “install shower” without listing materials
• No proof of license, liability insurance, or workers’ compensation
• No mention of a permit when the valve or drain is being replaced

Ask each contractor how they waterproof the shower, how they handle hidden damage if they find it, and what warranty they offer on materials and labor.

Long-term costs and upkeep

Prefab and panel showers need only regular cleaning. Tiled showers need grout and caulk to be kept in good shape, and cement-based grout should be sealed periodically. A squeegee after each shower helps prevent hard-water spots and mildew on glass. A WaterSense-labeled shower head, which uses no more than 2.0 gallons per minute, can lower water and water-heating costs compared with older heads.

Frequently asked questions

How much does a walk-in shower cost?

Most walk-in showers cost about $3,000 to $11,000 installed. Replacing an existing shower with a prefab kit usually costs about $2,700 to $6,200, a typical tub-to-tile-shower conversion runs about $5,300 to $10,600, and a large curbless or stone shower can pass $15,000.

How much does it cost to convert a tub to a walk-in shower?

Converting a standard tub to a walk-in shower typically costs $3,500 to $7,800 with a prefab kit and framed door, or $5,300 to $10,600 with a tiled shower and semi-frameless glass. Moving the drain and building a new shower pan are the main extra costs compared with replacing a shower.

Is a prefab or tiled shower cheaper?

Prefab acrylic and fiberglass kits are the cheapest option and install in a day or two. Tiled showers cost more because of waterproofing, pan construction, and tile labor, but they can be any size and shape and offer far more design choices.

How much does a curbless shower cost?

A curbless, or zero-entry, shower usually adds $1,500 to $3,500 to a tiled shower because the floor has to be recessed or sloped and a linear drain is often needed. Most curbless showers end up costing $7,500 or more installed.

Does a walk-in shower add value to a home?

A well-built walk-in shower can make a bathroom more appealing to buyers, especially in a primary suite. Keep at least one bathtub in the home if you can, since many families with young children look for one.

How long does it take to install a walk-in shower?

A prefab shower can be installed in one to three days. A tiled shower usually takes one to two weeks, including time for waterproofing and mortar to cure, inspections, and glass that’s measured after the tile is done.
