Tub to Shower Conversions in Rapid City, SD
Get Your Free QuoteWhy Rapid City Homeowners Are Converting Tubs to Showers
Across the Black Hills, homeowners are realizing that the bathtub they never use is wasting valuable bathroom space. If your tub serves as nothing more than a shower with high walls, a tub-to-shower conversion gives you a larger, more accessible, and more modern bathing area in the same footprint. It is one of the most popular and impactful bathroom upgrades we perform at Black Hills Premier Interiors.
A tub-to-shower conversion involves removing the existing bathtub, reconfiguring the plumbing for a shower drain and valve, building a properly sloped and waterproofed shower base, and finishing with your choice of tile, glass, and fixtures. The result is a custom walk-in shower built in the space your bathtub used to occupy — typically a 60-by-30-inch or 60-by-32-inch alcove that becomes a comfortable shower with room for a bench, niche, and glass enclosure.
Owner Bruce Miller has converted hundreds of bathtubs to showers across Rapid City and the surrounding communities over his 50-year career. He understands the structural, plumbing, and waterproofing challenges that this conversion presents, and he handles every one of them as a licensed general contractor. The result is a shower that looks like it was always part of the original home — not an afterthought bolted into a tub space.
Benefits of Converting Your Bathtub to a Shower
More Usable Space
A standard alcove tub takes up the same footprint as a walk-in shower, but high tub walls make the space feel cramped and restrict movement. A walk-in shower with a glass enclosure or open entry feels dramatically larger and more comfortable to use every day. Many homeowners are surprised by how much larger their bathroom feels after the conversion.
Improved Accessibility
Stepping over a tub wall is a daily fall risk, especially for older adults, anyone with mobility limitations, and families with young children. A walk-in shower with low or zero threshold eliminates that barrier entirely. For homeowners planning to age in place in Rapid City, this conversion is one of the most impactful safety upgrades you can make.
Modern Appearance
Walk-in showers with frameless glass, custom tile, and modern fixtures are one of the most sought-after features in today’s home designs. A tub-to-shower conversion instantly modernizes the bathroom and adds significant resale value, especially in the competitive Rapid City housing market where updated bathrooms drive buyer interest.
Easier Maintenance
Bathtubs collect soap scum, hard water deposits, and grime in every crevice and seam. A walk-in shower with large-format tile and minimal grout lines is significantly easier to clean and maintain. No more scrubbing around faucet plates, overflow covers, and tub-to-wall joints that trap mold and mildew.
Water Efficiency
A typical bath uses 35 to 50 gallons of water, while a shower uses 15 to 25 gallons. If the tub is only being used as a shower anyway, converting to a dedicated shower does not change your water usage — but if family members occasionally take baths out of habit, the switch to shower-only can reduce your water bill noticeably.
Custom Features
Converting to a shower opens up options that a tub-shower combo cannot accommodate: a built-in bench, recessed niches at multiple heights, rain showerhead, body spray jets, linear drain, and full-wall tile designs. You get to build the shower you actually want instead of working around a tub you never use.
Our Tub-to-Shower Conversion Process
Free Consultation and Design
Bruce visits your home to measure the existing tub space, evaluate the plumbing layout, and discuss your vision for the new shower. He will advise on the best shower configuration for your space — including entry style, drain placement, bench position, niche location, and glass options. You receive a detailed quote covering every aspect of the conversion.
Bathtub Removal and Inspection
The existing bathtub, surround, and any tub-specific plumbing are removed. Bruce inspects the subfloor, wall framing, and drain line for damage or issues. In many Rapid City homes — especially those built before the 1990s — this is where water damage, outdated galvanized plumbing, or inadequate subfloor support is discovered and addressed.
Plumbing Reconfiguration
A bathtub drain and a shower drain are in different locations and use different trap configurations. Bruce relocates the drain to the proper position for the new shower, installs a new shower valve at the correct height, and updates the supply lines. This plumbing work is where the general contractor license is essential — improper drain slope or trap configuration causes problems that are expensive to fix later.
Shower Base and Waterproofing
A mortar shower bed is built with proper slope toward the drain, or a prefabricated shower base is installed depending on the design choice. A continuous waterproof membrane is applied to the floor and walls, with careful attention to every seam, corner, and pipe penetration. This waterproofing layer is what prevents moisture from reaching the subfloor and wall framing — it is the most critical step in the entire conversion.
Tile, Glass, and Finish Work
Tile is installed on the shower floor and walls with precision cutting and consistent grout lines. The bench and niches are tiled and sealed. Grout is applied and sealed. Glass panels or doors are measured, ordered, and installed. Fixtures are mounted, caulking is applied at every junction, and the shower is tested with running water before the final walk-through with you.
Why Choose Black Hills Premier Interiors for Your Conversion
Plumbing Expertise Built In
A tub-to-shower conversion is fundamentally a plumbing project with a tile finish. Moving the drain, reconfiguring the trap, relocating the valve — these are the steps that determine whether your new shower works correctly for decades. Bruce’s general contractor license and 50 years of experience mean the plumbing is done right, not just the tile.
Waterproofing You Can Trust
The number one reason tub-to-shower conversions fail is inadequate waterproofing. Bruce uses proven waterproof membrane systems, seals every penetration and seam, and tests the installation before tile goes on. When your shower is built on a bulletproof waterproof foundation, you do not worry about leaks, mold, or rot behind the walls.
50 Years of Conversions
Bruce has converted more bathtubs to showers than he can count across Rapid City, Spearfish, Sturgis, Box Elder, and communities throughout western South Dakota. He has seen every plumbing configuration, every subfloor condition, and every complication that tub spaces can present. That experience translates directly into a smoother project and a better result for you.

Important Considerations Before Converting
Before committing to a tub-to-shower conversion, there are a few factors every Rapid City homeowner should think about. Bruce discusses all of these during the free consultation to make sure a conversion is the right choice for your home.
Keep At Least One Tub
Real estate professionals in the Rapid City market generally recommend keeping at least one bathtub in the home for resale value. Families with young children need a tub for bath time, and some buyers simply prefer having the option. If your home has multiple bathrooms, converting one tub to a shower while keeping a tub in another bathroom is the ideal approach. If you have only one bathroom, weigh the daily convenience of a shower against the potential impact on resale.
Conversion Options
You have several choices for the finished shower: a custom tile shower with glass enclosure is the premium option, while a prefab shower base with wall panels is a more budget-friendly route. Bruce can also build a curbless (zero-threshold) shower for maximum accessibility, though this may require more significant floor modifications. He will explain the pros and cons of each option for your specific space and budget.
Tub to Shower Conversion FAQs
How much does a tub-to-shower conversion cost in Rapid City?
Tub-to-shower conversions in Rapid City typically range from $3,500 to $10,000 depending on the approach. A prefab shower base with wall panels is on the lower end, while a custom tile shower with frameless glass, built-in bench, and niches is on the higher end. The price includes tub removal, plumbing reconfiguration, waterproofing, and all finish work. Bruce provides a detailed quote during the free consultation.
How long does a tub-to-shower conversion take?
A standard conversion with a prefab shower base and wall panels can be completed in two to three days. A custom tile shower with glass enclosure typically takes five to ten days depending on the tile layout, waterproof membrane curing time, and grout drying time. Bruce provides a specific timeline during the consultation based on your chosen design.
Will converting my only tub hurt my home value?
If you have multiple bathrooms, converting one tub to a shower typically increases home value — walk-in showers are among the most desired bathroom features. If you have only one bathroom, some real estate agents recommend keeping the tub for buyer appeal. However, a well-built walk-in shower can be more attractive than an old, dated tub. Bruce and your real estate agent can help you decide what is best for your situation.
Can I convert my tub space to a walk-in shower with no threshold?
Yes. A curbless (zero-threshold) shower is possible in most tub alcoves, though it requires modifying the floor structure to create the proper slope for drainage. This is a more involved conversion than a standard curbed shower, but the result is a beautiful, accessible shower that is especially popular for aging-in-place modifications. Visit our walk-in showers page to see more options.
Do you need to modify the plumbing for a conversion?
Yes. The drain location and trap configuration differ between a bathtub and a shower. The tub drain is typically at one end while a shower drain is centered or positioned for optimal flow. The shower valve also mounts at a different height than a tub faucet. Bruce handles all plumbing modifications as part of the conversion — no separate plumber needed.
What if I decide I want a new tub instead of a shower?
If you are not ready to give up the tub, our replacement bathtub service can install a new, modern tub in the same space. For the fastest option, our one-day bath installation can have a new tub in place within a single day. Bruce will walk you through all options during the free consultation so you can make the right choice for your household. Call (605) 636-2284 or visit our contact page to get started.
