Walk-In Shower vs Bathtub: Which Is Right for Your Boise Bathroom?
The shower-vs-tub decision shapes your daily routine, your home's resale value, and your long-term accessibility. Here is a data-driven comparison tailored to Boise-area homeowners — covering cost, space, water usage, aging-in-place considerations, and what the Treasure Valley real estate market actually rewards.
Every bathroom remodel in the Boise metro area eventually arrives at the same question: walk-in shower, bathtub, or both? The answer depends on which bathroom you are remodeling, who uses it, your home's overall tub count, and your plans for the property over the next 10 to 20 years. There is no universal right answer — but there are clear best-fit scenarios that we see play out across hundreds of Treasure Valley bathroom projects every year.
Walk-in showers have surged in popularity in Boise master bathrooms over the past five years, driven by the demand for spa-like retreats, accessible design, and the visual openness that frameless glass enclosures provide. Meanwhile, bathtubs remain essential in family bathrooms, guest bathrooms, and any home where resale value to families with young children is a priority. The Boise real estate market consistently rewards homes that offer at least one bathtub — but it also increasingly values walk-in showers in the primary suite.
Below is a comprehensive, side-by-side comparison covering the seven factors that matter most to Boise homeowners making this decision: cost, space, accessibility, water usage, resale value, maintenance, and installation time.
This comparison reflects real-world pricing and performance data from bathroom remodels we have completed in Boise, Meridian, Eagle, Nampa, and surrounding Treasure Valley communities. All cost figures are 2026 installed prices including labor and materials.
| Factor | Walk-In Shower | Bathtub |
|---|---|---|
| Installed Cost (Boise) | $5,000–$18,000 | $2,500–$12,000 |
| Space Required | 9–15 sq ft | 13–21 sq ft |
| Accessibility | Excellent (curbless option) | Poor (high step-over) |
| Daily Water Usage | 12–20 gallons | 36–50 gallons |
| Resale Value Impact | High (master bath) | High (family homes) |
| Cleaning/Maintenance | Moderate (glass, grout) | Low (simple surfaces) |
| Installation Time | 5–8 days | 3–5 days |
Cost ranges reflect standard to premium tier installations. Walk-in shower high-end includes curbless entry, large-format tile, frameless glass, and multi-head plumbing. Bathtub high-end includes freestanding soaking tub with custom surround tile. Actual costs vary by bathroom layout, plumbing complexity, and material selections.
Walk-in showers generally cost more than bathtub installations in the Boise market, primarily because of the custom tile work, waterproofing systems, and glass enclosures involved. A basic alcove bathtub replacement with a standard tile surround runs $2,500 to $5,000 installed. A mid-range walk-in shower with ceramic tile, a pre-formed shower pan, and a framed glass door starts at $5,000 to $8,000.
The cost gap widens at the premium tier. A custom walk-in shower with a curbless entry, linear drain, large-format porcelain tile, frameless glass enclosure, built-in niche, and rain shower head can reach $13,000 to $18,000 in Boise. A comparable premium bathtub installation — freestanding soaking tub with deck-mount filler, custom tile surround, and integrated storage — typically runs $8,000 to $12,000.
For tub-to-shower conversions specifically, expect to add $1,000 to $3,000 above the cost of a new-construction shower installation due to plumbing relocation, drain repositioning, and subfloor modifications required to convert the existing tub footprint.

The Boise real estate market has a clear pattern when it comes to showers and tubs. Walk-in showers in the master bathroom are considered a premium upgrade that appeals to a broad range of buyers, from young professionals in the Boise Bench to empty nesters in Eagle. Listing agents in Ada County consistently report that a well-executed walk-in shower with frameless glass is one of the top three features buyers comment on during showings.
However, removing the only bathtub in the home is a resale risk. Families with young children — a significant buyer demographic in Meridian, Star, Kuna, and Southeast Boise — strongly prefer homes with at least one tub for bathing kids. Homes listed without any bathtub in the Treasure Valley MLS data tend to sit on the market 8 to 15 days longer and receive 3 to 5 percent lower offers compared to comparable homes with at least one tub.
The highest-return configuration in the Boise market is a walk-in shower in the master bathroom combined with a standard tub (or tub-shower combo) in the secondary bathroom. This layout satisfies both the spa-lifestyle buyer and the family buyer, maximizing your resale audience. If your home has only one full bathroom, we strongly recommend keeping the bathtub or choosing a tub-shower combination rather than converting to a shower-only layout.
Bathroom falls are the leading cause of home injury for adults over 65, and the bathtub step-over is the single highest-risk movement in a typical bathroom. Standard bathtub walls are 14 to 16 inches high — a significant obstacle for anyone with limited mobility, balance issues, or joint pain. Walk-in showers, particularly curbless designs, eliminate this barrier entirely.
For Boise homeowners planning to age in place, a curbless walk-in shower is the gold standard. The design allows zero-threshold entry from the bathroom floor directly into the shower, accommodates a built-in or freestanding shower bench, and provides clearance for a wheelchair or walker if needed in the future. Key accessibility features to include during your remodel:
Curbless Entry with Linear Drain
Eliminates any step or lip. The floor slopes gently toward a linear drain at the shower perimeter, keeping water contained without a physical barrier.
Blocking for Future Grab Bars
We install solid wood blocking behind the tile at strategic locations so grab bars can be mounted securely later without tearing into finished walls.
Anti-Slip Flooring
Small-format mosaic tile (2x2 or smaller) with more grout lines provides superior traction compared to large-format floor tiles. Textured porcelain is another excellent option.
Handheld Shower Head on Slide Bar
Allows the user to adjust the shower head height from seated or standing positions. A dual shower head setup (fixed rain head plus handheld) offers maximum flexibility.
Minimum 36" x 60" Shower Footprint
This dimension provides adequate space for wheelchair access and caregiver assistance if needed in the future, meeting ADA residential guidelines.

Space is often the deciding factor in Boise bathroom remodels, especially in older homes on the Boise Bench, in the North End, and in mid-century ranches throughout Garden City and West Boise where bathrooms were built to 1960s and 1970s standards — typically 40 to 55 square feet for a full bathroom.
A standard alcove bathtub occupies a 30" x 60" footprint — 12.5 square feet of floor space. A walk-in shower can be built as compact as 32" x 36" (8 square feet) or as generous as 48" x 60" (20 square feet) depending on your layout goals. For small bathrooms under 50 square feet, a walk-in shower frees up 3 to 5 square feet of usable floor area compared to a standard tub — enough space for a wider vanity, additional storage, or simply more comfortable movement within the room.
Walk-in showers with frameless glass enclosures also create the perception of a larger bathroom because the glass allows sightlines to continue through the shower space. This visual openness is especially valuable in compact Boise bathrooms where a solid tub surround or shower curtain makes the room feel smaller than it is.

Water conservation matters in the Treasure Valley. Boise's water rates have increased steadily over the past decade, and the semi-arid climate of southwestern Idaho makes responsible water use a community priority. When comparing showers to baths, the daily water usage difference is significant for most households.
A standard bathtub filled to a comfortable soaking level uses 36 to 50 gallons of water per bath. A shower with a standard 2.0 GPM showerhead uses approximately 16 gallons for an 8-minute shower. A WaterSense-certified low-flow showerhead at 1.5 GPM drops that to about 12 gallons — less than one-third of a full bath.
For a household of two adults showering daily instead of bathing, the annual water savings is approximately 14,000 to 28,000 gallons. At Boise's current tiered water rates through Suez/United Water, that translates to roughly $80 to $160 per year in water and sewer cost savings — not counting the reduction in water heating energy. Over a 15-year period, the cumulative utility savings from switching from daily baths to daily showers can reach $1,200 to $2,400, partially offsetting the higher upfront cost of a walk-in shower installation.
One caveat: luxury rain shower systems and multi-head setups with flow rates of 5 to 8 GPM can consume as much or more water than a bath if shower times exceed 6 to 8 minutes. If water conservation is a priority, pair your walk-in shower with a quality low-flow showerhead — modern low-flow models deliver excellent pressure and coverage without the weak, unsatisfying spray of older water-saving designs.
Both walk-in showers and bathtubs offer extensive design flexibility, but the aesthetic direction differs significantly. Here is what each option brings to the table for Boise bathroom remodels.
Walk-In Shower Design Options
Walk-in showers are the primary design canvas in modern bathroom remodels. Options include frameless glass enclosures for a clean, open look; large-format porcelain slab walls that minimize grout lines; mosaic tile accent walls and shower floor patterns; built-in niches for shampoo and soap storage; bench seating in natural stone or matching tile; linear drains that integrate flush with the floor; and multi-head shower systems with rain heads, body jets, and handheld sprayers. The current design trend in Boise master bathrooms is toward large-format tiles (24" x 48" or larger) in neutral tones with matte black or brushed gold hardware — a look that pairs well with the modern farmhouse and transitional styles popular across the Treasure Valley.
Bathtub Design Options
Bathtub design has evolved well beyond the standard alcove tub. Freestanding soaking tubs — particularly in matte white, matte black, and natural stone finishes — have become statement pieces in Boise master bathroom remodels. Japanese-style deep soaking tubs offer full-immersion bathing in a compact footprint. Drop-in tubs with custom tile decks provide a built-in look with extensive material options. For smaller bathrooms, alcove tubs with decorative tile surrounds remain a practical and attractive choice. Freestanding tub fillers (floor-mounted or wall-mounted) add a boutique hotel aesthetic that resonates strongly with Boise buyers. Explore more ideas in our bathroom design ideas gallery.
The right choice depends on which bathroom you are remodeling. Here is how we advise Boise homeowners based on the hundreds of bathroom projects we have completed across Ada and Canyon County.
Master Bathroom
Walk-in shower is the top choice. The primary suite is used by adults who overwhelmingly prefer showers for daily use. A curbless walk-in shower with frameless glass, rain head, and built-in bench creates a spa-like retreat that adds significant value. If space allows, add a freestanding soaking tub as a secondary fixture for the ultimate master bath configuration.
Kids' Bathroom
Bathtub is essential. Young children need a tub for safe, practical bathing. A standard alcove tub-shower combo is the most versatile option — it serves kids now and converts easily to a walk-in shower later when they are grown. Prioritize durable, easy-to-clean materials like porcelain tile and a solid-surface tub.
Guest Bathroom
Tub-shower combo or bathtub with shower. Guests have varied needs, and a tub-shower combo covers all scenarios. If this is the only bathroom with a tub in the home, keep it — the resale value protection outweighs any aesthetic preference for a walk-in shower.
Basement Bathroom
Walk-in shower is typically the best fit. Basement bathrooms in Boise homes often have limited ceiling height and compact layouts where a walk-in shower makes better use of the available space. The lower ceiling also makes tub installation awkward for taller users.
Aging-in-Place / Accessible Bathroom
Walk-in shower is the clear choice. Curbless entry, grab bars, bench seating, and handheld shower heads make a walk-in shower the safest and most functional option for aging homeowners or anyone with mobility limitations.
Not every bathtub should be converted to a walk-in shower, and not every tub deserves to stay. Here is a practical decision framework based on what we see in the Boise market.
Convert to a Walk-In Shower When:
- Your home has two or more bathtubs and you rarely use one of them
- You are remodeling the master bath and want a spa-like daily shower experience
- Mobility or aging-in-place concerns make the tub step-over unsafe
- The bathroom is under 50 square feet and a shower would free up critical floor space
- You are adding a freestanding tub elsewhere in the home as part of a broader remodel
Keep the Bathtub When:
- It is the only bathtub in the home — removing it hurts resale in the Boise market
- Young children live in the home and need the tub for daily bathing
- The bathroom serves as the primary guest bathroom
- You plan to sell the home within 2 to 3 years and the buyer pool includes families
- You genuinely use and enjoy soaking baths as part of your routine
Does removing the only bathtub hurt resale value in Boise?
Yes, removing the only bathtub in a home can negatively impact resale value in the Boise market. Homes with at least one bathtub consistently sell faster and closer to asking price in Ada and Canyon County, particularly in neighborhoods that attract families with young children such as Southeast Boise, North Meridian, and Eagle. Real estate agents in the Treasure Valley generally advise keeping at least one tub in the home, even if you convert the master bathroom to a walk-in shower. If your home has two or more full bathrooms with tubs, converting one to a walk-in shower is unlikely to hurt resale and may actually increase appeal to buyers who prioritize accessible, spa-like master bathrooms.
How much does it cost to convert a bathtub to a walk-in shower in Boise?
A bathtub-to-walk-in-shower conversion in the Boise metro area typically costs between $6,000 and $15,000, depending on the scope of work. A basic conversion using a prefabricated shower pan and standard tile surround runs $6,000 to $9,000. A mid-range custom tile shower with a linear drain, frameless glass enclosure, and niche storage runs $9,000 to $13,000. A premium conversion with large-format porcelain slab walls, curbless entry, multiple shower heads, and built-in bench runs $13,000 to $18,000 or more. The primary cost variables are the shower enclosure type (framed vs. frameless glass), tile material and layout complexity, plumbing relocation requirements, and whether the subfloor needs reinforcement or waterproofing membrane replacement.
Is a walk-in shower or bathtub better for aging in place in Boise?
A walk-in shower is significantly better for aging in place. Stepping over a standard bathtub wall (typically 14 to 16 inches high) is one of the leading causes of bathroom falls among older adults. A curbless or low-threshold walk-in shower eliminates this barrier entirely and can accommodate a shower bench, grab bars, handheld shower head, and anti-slip flooring without any aesthetic compromise. For Boise homeowners planning to age in place, we recommend a curbless shower with a linear drain, blocking installed behind the walls for future grab bar placement, and a minimum 36-by-60-inch shower footprint to allow wheelchair or walker access if needed in the future. These features add approximately $1,500 to $3,000 to the project cost but can eliminate the need for a much more expensive bathroom renovation later.
Which uses less water — a shower or a bath?
A standard shower uses significantly less water than a bath in most cases. A typical bathtub holds 36 to 50 gallons of water when filled for a bath. A standard showerhead flows at 2.0 gallons per minute (the federal maximum), meaning an 8-minute shower uses approximately 16 gallons — less than half the water of a full bath. Low-flow showerheads rated at 1.5 GPM reduce that further to about 12 gallons per shower. For Boise homeowners concerned about water costs and conservation in the Treasure Valley, the shower is the clear winner on daily utility costs. However, large rainfall shower systems and multi-head setups can increase flow rates to 5 to 8 GPM, potentially exceeding bath water usage if shower times are long. The key is matching the showerhead flow rate to your usage habits.
Can I have both a walk-in shower and a freestanding tub in my Boise bathroom?
Yes, and this is one of the most popular master bathroom configurations in Boise-area remodels. A combined walk-in shower and freestanding soaking tub gives you the best of both worlds: the daily convenience and accessibility of a walk-in shower plus the resale value and relaxation appeal of a tub. This layout typically requires a minimum bathroom footprint of approximately 80 to 100 square feet to accommodate both fixtures comfortably with proper clearances. In a typical Boise master bathroom remodel, a walk-in shower with frameless glass plus a freestanding soaking tub adds $12,000 to $22,000 to the project depending on materials, fixtures, and tile selection. This configuration consistently tests as the highest-value master bathroom layout in the Boise real estate market.
