Walk-In Shower vs Bathtub in Boise: Which Is Better for Your Home's Value?

Should you keep the bathtub or convert to a walk-in shower? It is the single most common question we hear from Boise homeowners planning a bathroom remodel, and the answer is more nuanced than the internet makes it seem.

Walk-in showers have dominated bathroom design magazines and social media for years, creating an impression that bathtubs are relics of a bygone era. But the reality in Boise's housing market is more complicated, and the honest answer is a conditional one: it depends on which bathroom you are remodeling, how many bathrooms your home has, and who is likely to buy your home when you sell.

In neighborhoods like Eagle, North Boise, and Southeast Boise, where homes tend to have multiple bathrooms and attract buyers who prioritize design and lifestyle, walk-in showers are the clear preference for master bathrooms. But in starter-home neighborhoods throughout Meridian, Kuna, and parts of West Boise, where homes often have only one or two bathrooms and young families are the primary buyers, removing the only bathtub can actually hurt resale value.

This guide breaks down every factor — cost, value, accessibility, water usage, space, and design — so you can make the right choice for your specific Boise home. Whether you are remodeling a master suite, a hall bath, or the only bathroom in a historic North End bungalow, the right answer is here.

Resale value is often the deciding factor for Boise homeowners, so it is worth being straight about what is actually known and what is folklore.

What is not known: there is no published, Boise-specific figure for how much a walk-in shower adds to a home's price, how much longer a tubless home sits on the market, or what share of buyers insist on a tub. Numbers like that circulate freely in remodeling content and none of them trace back to a source you can check. We are not going to invent one here.

What is reasonable to say: Remodeling Magazine's Cost vs. Value report has consistently shown a midrange bathroom remodel recovering roughly three-quarters of its cost at resale (about 74%, 2024 national). That figure is for the remodel as a whole, not for the shower-versus-tub decision inside it.

The structural logic that does hold up:

• A home with no bathtub anywhere excludes a category of buyer. Anyone bathing small children needs a tub, and a buyer who needs one and does not find one moves on. This is not a statistic; it is arithmetic about who can use the house.
• A walk-in shower in the primary bathroom is a broadly safe choice when at least one tub remains elsewhere in the home, because it adds appeal without removing a function.
• Converting a hall bath tub to a shower in a home whose primary bath already has a tub is generally the low-risk version of the same move.
• A shower and a freestanding tub as separate fixtures is the configuration buyers expect at the top of the market — but it needs real square footage, typically 100+ SF for the wet area alone, so it is a space question before it is a value question.

The practical key is matching the bathroom configuration to how many bathrooms you have and who realistically buys homes like yours — not to a percentage.

Bottom line for Boise: do not remove the only bathtub in a home that attracts family buyers. In homes with two or more bathrooms, converting the master tub to a walk-in shower while keeping a tub in the hall or secondary bath is the winning strategy for both lifestyle and resale.

Understanding the cost difference between shower and tub options helps you align your budget with your goals. Here is what each option costs in the Boise market as of 2026:

Standard Bathtub Replacement (tub-in-tub)

• Alcove tub with tile surround: $3,000-$6,000
• Freestanding soaking tub (installed): $2,500-$8,000
• Whirlpool/jetted tub (installed): $4,000-$10,000

Tub-to-Shower Conversion and New Walk-in Showers

Shower work in Boise runs $8,500 to $35,000, averaging around $17,500. Those figures include the waterproofing and substrate work that sits behind the tile, which is where the money that matters actually goes. The tiers:

• Basic tub-to-shower conversion — $8,500-$14,000. Remove the original tub, build a properly waterproofed shower pan (Schluter KERDI or equivalent), tile the walls and floor, and fit a basic frameless or semi-frameless enclosure, staying inside the existing alcove.
• Mid-range — $14,000-$22,000. Large-format tile (12x24 or 24x48), a recessed niche, a built-in bench, a full frameless glass enclosure, and better fixtures.
• High-end — $25,000-$35,000+. Premium materials, book-matched stone-look porcelain, custom frameless glass, linear drains, or a steam system — and typically a full bathroom gut rather than a shower swap.
• Secondary or hall bath refresh — $8,500-$12,500. Re-tile over new waterproofing, replace a failing pan, new valve and fixtures, practical tile. Same waterproofing standard, less of the luxury scope.

Substrate remediation found after demolition — rot, mold, compromised framing — is quoted separately and is more common in pre-1980 Boise homes than most homeowners expect.

The cost differential between keeping a tub and converting to a shower depends heavily on scope. If you are simply swapping an old alcove tub for a new one with fresh tile, the tub option is cheaper. But most homeowners converting to a walk-in shower are also expanding the shower footprint, upgrading tile, installing frameless glass, and improving the drain system — all of which add cost but also add significant value and daily enjoyment.

Converting a bathtub to a walk-in shower is one of our most frequently performed projects in Boise. The process is well-defined, but understanding each step helps you plan effectively. Here is what a tub-to-shower conversion looks like from start to finish:

Step 1: Design and Planning (1-2 weeks)

We assess the existing bathroom layout, determine if the shower footprint can be expanded (often possible by borrowing space from an adjacent closet), select tile, fixtures, glass, and drain configuration. If the shower will be barrier-free (curbless), a pre-slope evaluation of the subfloor is essential.

Step 2: Demolition (1 day)

The old tub, surrounding tile or surround panels, and the tub drain are removed. The subfloor and wall framing are inspected for water damage — in older Boise homes, particularly those in the North End and Bench neighborhoods built before 1980, compromised subfloor around the tub is a common enough find that it belongs in the contingency rather than in the surprise column. Repair costs for water-damaged subfloor range from $300-$1,200.

Step 3: Plumbing Rough-In (1 day)

The tub drain is converted to a shower drain (relocated if the layout is changing). The mixing valve is updated — modern shower valves from Moen, Kohler, and Delta are pressure-balanced and thermostatic, a significant safety improvement over the older two-handle valves found in many Boise homes. If adding body sprays or a handheld, additional supply lines are run during this phase.

Step 4: Waterproofing (1-2 days)

This is the most critical step. A proper waterproof membrane system (Schluter KERDI, Laticrete HYDRO BAN, or RedGard) is applied to the shower walls and floor. The shower pan is built with proper slope to the drain — a minimum 1/4" per foot. Every seam, corner, niche, and penetration gets waterproof treatment. Skipping or rushing this step is what puts a shower on the path to failure, and in Boise's dry climate, a leak behind a shower wall can go undetected for years before mold becomes visible. Learn more in our waterproofing systems guide.

Step 5: Tile Installation (2-4 days)

Wall and floor tile are set over the waterproof membrane. Grout is applied and sealed. In Boise, we recommend sealing grout lines annually in showers because our hard water — about 6 grains per gallon system-wide and up to roughly 13 in well-fed zones, per Veolia Water Idaho's 2023 water quality report — accelerates mineral buildup and staining in unsealed grout.

Step 6: Glass Enclosure (1 day, after tile cure time)

Frameless glass enclosures are custom-measured after tile is installed to ensure precise fit. Lead time for custom glass in Boise is typically 2-3 weeks from measurement to installation.

Step 7: Fixtures and Finish (1 day)

Shower heads, handles, drain covers, towel bars, and accessories are installed. The shower is tested for leaks and proper operation.

Total timeline for a typical tub-to-shower conversion in Boise: 7-14 working days, with glass lead time potentially extending the calendar duration to 3-4 weeks.

Accessibility is one of the strongest arguments for walk-in showers, and it is a factor that Boise homeowners increasingly prioritize — regardless of their current age.

The step-over problem with bathtubs: A standard bathtub has a 14-16 inch high rim that must be stepped over to enter. For adults over 60, individuals recovering from surgery, anyone with balance issues, or parents carrying children, this step-over is a fall risk. The CDC reports that falls are the leading cause of injury and injury-related death among adults 65 and older. Climbing over a wet, slick 14-16 inch wall on one leg is exactly the kind of movement that produces them, which is why the step-over is the first thing to go when a bathroom is being designed for the long term.

Walk-in shower advantages for accessibility:

• Low-threshold or curbless entry: A well-designed walk-in shower can have a threshold as low as 1/2 inch (or zero for fully curbless showers). This eliminates the step-over hazard entirely and allows wheelchair access if ever needed.
• Built-in bench seating: Tiled shower benches provide a comfortable and safe place to sit while showering. For post-surgery recovery, this can be the difference between needing assistance and showering independently.
• Grab bar integration: Grab bars installed during construction are mounted to blocking in the wall framing, providing rated support (250+ lbs). They can be designed to look like sleek towel bars or shower shelves rather than institutional assists.
• Handheld shower head on a slide bar: Adjustable height for seated or standing use. This is standard in ADA-compliant showers and is increasingly popular in Boise master bathrooms for all ages.

For Boise homeowners planning to age in place, we recommend installing the structural blocking for grab bars during any shower remodel, even if you do not install the bars immediately. Adding blocking to a finished shower wall later requires opening up the wall — a much more expensive proposition. Our accessible walk-in shower service includes ADA-compliant design options, and our accessible bathroom remodel guide covers the full spectrum of aging-in-place features.

When a tub is the accessibility choice: For homeowners who have mobility limitations that make standing difficult, a walk-in bathtub (Kohler Walk-In Bath, American Standard Liberation) provides seated bathing without the step-over. These specialized tubs have a door that opens to allow entry while seated and seals watertight when closed. Cost: $5,000-$12,000 installed in Boise. They are larger than standard tubs and require adequate space and a dedicated water heater capacity for the higher fill volume.

Water efficiency matters in Boise. The Treasure Valley sits in a semi-arid climate, and periodic drought conditions have prompted water conservation awareness across the community. How do showers and baths compare on water usage?

Average bath: A standard bathtub filled to a comfortable soaking level uses 35-50 gallons of water. A large soaking tub or freestanding tub can use 50-80 gallons.

Average shower: The federal maximum for a shower head is 2.5 GPM; the EPA's WaterSense label requires 2.0 GPM or less. At 2.0 GPM a 10-minute shower uses 20 gallons. A 1.5 GPM head reduces that to 15 gallons for the same shower duration.

On those numbers a typical shower uses well under half the water of a typical bath, and the gap compounds over a year of daily use.

There is a caveat, however: long showers erase the advantage. A 20-minute shower at 2.0 GPM uses 40 gallons — right in bathtub territory. Luxury multi-head shower systems with body sprays and rain heads can flow at 4-6 GPM combined, which means a 10-minute luxury shower uses as much water as filling a bathtub. If water conservation is a priority, pair your walk-in shower with a WaterSense-labeled shower head and be mindful of duration.

Hot water considerations for Boise: incoming water is cold through an Idaho winter, so your water heater works considerably harder in January than in July to deliver the same showering temperature (typically 104-110 degrees). If you are converting from a tub to a large walk-in shower with multiple heads, verify that your water heater has adequate capacity and recovery rate. A 50-gallon tank water heater is usually sufficient for a single-head shower. Multi-head shower systems may require a 75-gallon tank or a tankless water heater upgrade ($2,500-$4,500 installed in Boise).

Bathroom square footage is often the practical constraint that determines whether a shower or tub makes sense. Understanding the space requirements helps you maximize your layout.

Standard tub footprint: 30" x 60" (12.5 SF). An alcove tub fits neatly into a three-wall alcove and is the most space-efficient bathing option. It provides both bathing and showering functionality in a minimal footprint — which is why it remains the default in Boise's smaller secondary bathrooms and guest baths.

Freestanding tub footprint: 30" x 60" to 36" x 72" for the tub itself, but you need clearance on all sides — typically 6" minimum, 12" preferred. Total floor area: 20-30 SF. This is why freestanding tubs only work in larger master bathrooms (70+ SF total).

Walk-in shower footprint: The code floor under the 2018 IRC (Idaho's adopted residential code) is section P2708.1 — a shower compartment must be at least 30 inches in any dimension and provide at least 1,024 square inches of floor area, which works out to about 32 inches square. That is a legal minimum, not a comfortable one. A practical minimum is 36" x 36" (9 SF), but most comfortable walk-in showers are at least 36" x 48" (12 SF) or ideally 36" x 60" (15 SF) or larger. A curbless shower with a bench and frameless glass needs approximately 15-20 SF to function well. A luxury walk-in shower with multiple heads, a bench, and room to move comfortably needs 20-30 SF.

Space optimization strategies for Boise bathrooms:

• Borrow from adjacent closets: In many Boise homes, the master bathroom shares a wall with a bedroom closet. Pulling 12-18 inches from the closet can transform a tight 36" x 36" shower into a comfortable 48" x 36" or larger.
• Linear drain placement: A linear drain along one wall allows the entire shower floor to slope in one direction, enabling wider format tiles that look more expansive. Linear drains also allow the shower to be wider at the entrance — important for accessibility.
• Glass enclosure instead of curtain: Frameless glass makes a small shower feel larger by allowing light to pass through and maintaining visual continuity. In a compact Boise hall bathroom, this is one of the most impactful upgrades.
• Niche storage instead of corner caddies: Built-in tile niches keep products off the floor and out of the way, making the shower feel more spacious. Standard niche size: 12" wide x 24" tall x 3.5" deep. Cost: $300-$800 installed during a tile shower project.

When Boise homeowners commit to a walk-in shower, they increasingly want a spa-level experience rather than a basic shower enclosure. Here are the luxury shower features driving the most demand in Treasure Valley bathroom remodels:

Rain shower heads. Overhead-mounted rain heads (8"-12" diameter) deliver a gentle, full-coverage flow that feels dramatically different from a wall-mounted shower head. Ceiling-mounted rain heads from Kohler (Statement, Rainhead line) and Moen (Velocity) are the most-requested fixtures in our Boise shower remodels. Cost: $200-$1,200 for the head, plus $500-$1,500 for the ceiling-mount plumbing rough-in.

Body sprays. Wall-mounted body spray jets (typically 3-6 per shower) provide a hydrotherapy experience. They are positioned at hip and shoulder height and deliver horizontal water streams. Body sprays require a thermostatic valve system with dedicated volume controls — a step up from the standard pressure-balanced valve. Budget $2,000-$5,000 for a body spray system including valve, sprays, and plumbing.

Steam generators. A steam shower transforms your enclosure into a personal steam room. A small steam generator (installed outside the shower, often in a vanity cabinet or closet) delivers steam through a head mounted at the lower wall. The shower must be fully enclosed (floor to ceiling glass or a solid enclosure) to contain the steam. Cost: $2,500-$6,000 for generator, steam head, and controls. The shower enclosure must also have a sloped ceiling to prevent condensation drips — a detail your contractor must plan during framing. Steam showers are popular in Eagle and North Boise luxury homes.

LED shower lighting. Recessed LED downlights in the shower ceiling, chromotherapy (color-changing) LED fixtures, and illuminated niche lighting add atmosphere. Wet-location-rated LED fixtures are required. Cost: $300-$1,500 depending on the number and type of fixtures.

Heated shower bench. Electric radiant heating under the tile bench surface keeps the seat warm before and during your shower. This is a small luxury that has an outsized impact on the showering experience, especially during Boise's cold mornings from November through March. Cost: $400-$900 for the heating element, installed during tile work.

Curbless (barrier-free) entry. A curbless shower eliminates the threshold entirely, creating a seamless transition from the bathroom floor into the shower. It is the most visually dramatic shower design and the most accessible. The floor slopes gently toward a linear drain. Curbless showers require careful subfloor engineering (the pre-slope must be built into the floor structure) and waterproofing. Cost premium over a curbed shower: $1,000-$3,000.

In real estate and remodeling circles, the "one-tub rule" is well known: every home should have at least one bathtub to maintain broad buyer appeal. Here is how to apply this principle to your Boise home:

One-bathroom homes: Keep the tub. Full stop. Removing the only tub from a one-bathroom home in Boise narrows your buyer pool, and it does so in a way you cannot undo cheaply. Any household bathing small children will pass over a home with nowhere to do it. Consider a tub/shower combination (alcove tub with a shower head and curtain or glass panel) to get both functions in one fixture.

Two-bathroom homes: Keep a tub in one bathroom. If you are remodeling the master bathroom and it is one of two, you can convert the master to a walk-in shower as long as the second bathroom retains a tub. This is the most common configuration in Boise's two-bath homes and satisfies both the desire for a modern shower experience and the resale need for a tub.

Three or more bathrooms: You have flexibility. Convert the master to a walk-in shower. Keep a tub in at least one secondary bathroom — ideally the hall bath that is most accessible to kids' bedrooms. The third bathroom can be a shower-only configuration (common for basement baths and guest suites).

Exceptions to the one-tub rule in Boise:

• 55+ communities and retirement-oriented homes: Buyers downsizing into age-restricted housing are generally shopping for accessibility rather than for a tub, so a shower-only bathroom is less of a liability — and a curbless one may be an advantage.
• The top of the market: Buyers at that level expect a primary bathroom with both a walk-in shower AND a freestanding soaking tub as separate fixtures. Here, removing the primary tub for shower-only is the risky move unless the shower is genuinely exceptional.
• Investment properties: Shower-only configurations in all bathrooms maximize durability and minimize maintenance. Tenants are less likely to cause water damage with a shower than a bathtub.

Here is our decision framework from remodeling bathrooms across the Treasure Valley:

Choose a walk-in shower if:

• You are remodeling the master bathroom AND at least one other bathroom has a tub
• You rarely or never take baths
• Accessibility is a current or future priority
• You want to create a spa-like daily experience
• Your bathroom is small and a walk-in shower will use space more efficiently than a tub
• A well-executed shower will match what buyers see in comparable homes on your street

Choose a bathtub (or keep the existing one) if:

• It is the only bathroom in the home with a tub
• You have young children or plan to have them
• You are an avid bath taker and it is a daily wellness practice
• The bathroom is a secondary/hall bath used by kids
• Homes like yours sell to families with small children, who need somewhere to bathe them

Choose both (if space allows) if:

• Your master bathroom is 70+ SF
• You want maximum resale appeal in the luxury market
• You enjoy both bathing and showering and do not want to compromise
• Your budget accommodates $15,000-$30,000 for the wet zone

Regardless of your choice, invest in quality waterproofing, proper ventilation, and durable materials. Boise's hard water — about 6 grains per gallon system-wide and up to roughly 13 in well-fed zones, per Veolia Water Idaho's 2023 water quality report — is hard on bathroom surfaces, which means matte finishes show mineral deposits less than glossy finishes, light-colored grout stays cleaner than dark, and glass treatments (like EnduroShield) that repel mineral buildup are worth the $200-$400 investment on frameless glass enclosures.
