Walk-In Shower vs. Tub-to-Shower Conversion: Which Is Right for You?

Two different projects, one label

A tub-to-shower conversion removes an existing tub or tub-shower combo and installs a shower in that exact footprint. Because the plumbing rough-in and the opening already exist, this is generally the faster and lower-cost path, and it's the most common way to retire a tub nobody in the house actually uses.

A walk-in shower is the broader term of the two. It can describe that same in-place conversion, or it can mean a larger, custom build — sometimes curbless with a zero-threshold entry — that expands past the old tub's dimensions entirely. The range runs from a prefab acrylic kit installed in a day to a fully tiled, glass-enclosed custom build.

What each path actually costs

Tub-to-shower conversion sits at the lower end because it reuses the existing footprint and rough plumbing — a prefab or acrylic swap is the affordable version, while converting that same space into a custom tiled shower runs higher. The two biggest swing factors are whether the plumbing has to move and which surround and floor materials you choose.

A standalone walk-in shower build climbs with size and finish level: a prefab acrylic kit is the entry point, and a fully custom tiled, glass-enclosed walk-in — especially one that expands beyond the tub's original footprint — is a considerably larger investment.

An accessible or curbless walk-in — zero-threshold entry, grab bars, a slip-resistant floor, comfort-height fixtures — runs about $9,500 on average with a $3,000–$15,000 range, per Fixr (2025/2026).

Clark County, Washington sales tax applies to both labor and materials on any of these scopes and is worth budgeting for separately, since it isn't always broken out in a rough estimate.

The safety and moisture case for a shower

The daily argument for converting is largely about safety: stepping over a low or zero threshold is measurably easier than swinging a leg over a tub wall, and that difference is not trivial — the CDC reports that 81.1% of nonfatal bathroom injuries are falls, with roughly 37% occurring while bathing, showering, or getting in or out of a tub.

There's a moisture argument that carries extra weight in a Pacific Northwest climate, where humidity and standing water are a near-constant condition rather than a seasonal one. A curbless or low-threshold shower with a properly sloped pan sheds water more predictably than an aging tub surround with worn caulk, and a large-format or grout-light surround gives mildew fewer seams to establish in. Pairing either option with a correctly sized exhaust fan — the Home Ventilating Institute recommends roughly 1 CFM per square foot of bathroom floor area — clears humidity before it lingers long enough to become a mold problem, something the EPA notes can begin within 24 to 48 hours of sustained dampness.

• Safer, lower-effort entry — meaningful for aging in place and limited mobility
• A properly sloped, low-threshold pan sheds water more predictably than an old tub surround
• Fewer seams and grout lines give mildew less of a foothold, especially with adequate exhaust ventilation
• Accessible remodels recoup roughly 64% of cost at resale (Remodeling 2025 Cost vs. Value)

The honest case for keeping a tub

Converting every tub in a house can work against you when it's time to sell. Standard real-estate guidance is to keep at least one bathtub somewhere in the home — ideally a main or family bathroom — both for resale appeal and for households currently or eventually bathing young children. Buyers shopping with small kids frequently pass on homes with no tub at all.

So if the bathroom you're considering holds the house's only tub, pause before converting it. A freestanding soaking tub added to a primary suite can satisfy a love of baths while a walk-in shower handles daily use elsewhere in the home.

• Keep at least one tub if this is the home's only one
• Households with young children often need a tub for bathing
• A freestanding tub in a primary suite can coexist with a walk-in shower elsewhere
• A completely tubless home can narrow the buyer pool at resale

Working through the decision

A short list of the factors that usually settle this, worked through in order:

• Household and life stage — aging in place or mobility needs favor a curbless walk-in; young children favor keeping a tub.
• Existing bathroom and tub count — with multiple bathrooms, converting one is low-risk; with only one bathroom, keep a tub somewhere.
• Budget — a straight conversion is the lower-cost path; a larger custom or curbless walk-in costs more.
• Layout — staying inside the existing footprint points to a conversion; expanding or reconfiguring points to a custom build.
• Resale strategy — keep at least one tub for buyers and families; lean on accessibility features for added value.
• Climate and upkeep — fewer grout seams and a properly waterproofed, curbless floor stay drier and more mildew-resistant than a tiled, curbed enclosure in a wet climate.

How this plays out at resale

Bathroom work holds its value well overall. A midrange bathroom remodel recoups about 80% of its cost nationally — the highest level since 2007 — per Remodeling's 2025 Cost vs. Value report, while accessible / Universal Design bathroom projects recoup roughly 64%.

Put simply: a thoughtful conversion or walk-in shower is generally a sound investment as long as the home isn't left without a single tub. Weigh the upgrade you'll use every day against what a future buyer is likely to expect.
