The Planning Decisions That Determine Shower Performance, Cost, and Longevity
When planning a shower renovation, many homeowners focus first on finishes and fixtures. However, long-term performance, usability, and cost are far more influenced by foundational decisions made early in the process.
After decades of hands-on remodeling experience, I can confidently say that shower design choices made during planning either protect a homeowner’s investment or create long-term maintenance problems that are expensive to correct later.
At MHM Remodeling, we’ve built and repaired hundreds of showers across Austin and the surrounding areas, and the difference between a shower that lasts five years and one that lasts decades almost always comes down to decisions made before tile is ever installed, particularly during the planning stage of a bathroom remodel.
This article explains the real differences between curbless and curbed showers, followed by three must-have features that apply to any properly built shower, regardless of style or budget.
Curbless vs. Curbed Showers: What Really Matters
In my experience, the single most important factor in determining whether a curbless shower is feasible is the home’s structure. This is not a design preference decision. It is a construction limitation. To build a true curbless shower correctly, the floor typically must be dropped approximately 2.5 to 3 inches to allow for proper slope, drainage, and waterproofing.
- Concrete slab homes require cutting or chipping the slab, which increases labor, dust control requirements, and overall cost
- Wood subfloor or pier-and-beam homes require framing modifications to recess the shower area
- Homes built with engineered or web trusses may not allow for the necessary floor drop without engineered solutions or alternative systems
One of the most common misconceptions I encounter is that curbless showers are a minor upgrade. In reality, they typically start $1,000–$2,000 higher in labor and structural work alone, before tile and finishes are even considered. Costs can increase further based on shower size, drain location, waterproofing method, and tile layout complexity.
For homeowners considering Bathroom Remodeling services, especially in homes with slab foundations, this cost difference should be evaluated early rather than after design expectations are set.
Because of this, I often advise against curbless showers when budget is a primary concern or when the goal is a cosmetic update. That said, curbless showers are an excellent solution for homeowners planning to age in place, those with mobility considerations, or anyone prioritizing a seamless, modern aesthetic.
Homeowners focused purely on short-term resale value are often better served by a properly built curbed shower.
When structure or budget is a limiting factor, alternatives such as low-profile prefabricated pans or ADA-style curbs can provide safer entry and a cleaner look without the complexity of a fully recessed floor.
Must-Have Feature 1: Seating That Improves Safety and Daily Use
When space allows, built-in seating is one of the most valuable functional upgrades in a shower.
In larger walk-in showers, benches improve comfort, convenience, and long-term usability. In smaller showers or tub-to-shower conversions, a properly placed footrest is often the more practical option.
- Free-floating benches provide a modern appearance and are easier to clean and maintain
- Box-style benches can work, but only when waterproofed correctly from the start
- Seating and footrests should always be planned during the design phase rather than added later
From a construction standpoint, adding seating after waterproofing is completed introduces unnecessary risk. Proper planning eliminates that risk.
Depending on layout and use, homeowners may benefit from a bench, a footrest, or both.
Must-Have Feature 2: Proper Storage That Works Long-Term
Shower storage is a daily-use feature and one of the first things homeowners notice when it is poorly planned.
Most homeowners choose recessed niches, and for good reasons. In many projects, I recommend a niche approximately 14 inches high by 24 inches wide, placed on the largest wall when possible.
Niches are integrated into the wall assembly, they must be planned before tile installation. Retroactive changes often lead to compromises or additional expenses.
- Standard showers typically include one oversized niche
- Larger or double showers often include separate niches for each shower station
- Niche placement can affect cost if plumbing must be relocated
While prefabricated waterproof niches are sometimes used for cost reasons, we typically build niches on site. We also never tile the niche sill. Instead, we install a solid surface sill, usually granite or engineered stone at 3cm thickness, for improved durability and better water control over time.
Must-Have Feature 3: Handheld Sprayers for Function and Flexibility
In nearly every shower renovation, I recommend including a handheld sprayer.
Handheld sprayers provide everyday practical benefits that fixed shower heads cannot.
- Easier cleaning of tile, glass, and fixtures
- Easy rinsing after daily use
- Improved usability for seated showering or mobility needs
- Easy to wash your four-legged friends
Placement depends on layout and use.
- In most showers, the handheld is placed on the same wall as the valve and main shower head
- When a bench is present, the handheld is often placed on the back wall for easier access while seated
- Flexibility (can be placed almost anywhere needed).
Equally important is how the handheld sprayer is controlled. We recommend using a dedicated diverter system rather than tying multiple functions into a single outlet. In most showers, a Delta three-way diverter allows two fixtures to operate independently or together at the same time. For more complex showers, a six-way diverter can control three individual fixtures and provide shared operation between them. Choosing the correct diverter at the planning stage ensures proper functionality, avoids flow issues, and prevents compatibility or warranty problems later.
Common mistakes include tying the handheld into the shower arm or mixing hardware brands. Both can lead to warranty issues and long-term compatibility problems.
While the final decision always belongs to the homeowner, in practice, every well-designed shower benefits from having a handheld sprayer.
Final Thoughts on Shower Design and Long-Term Performance
A well-built shower is about far more than appearance. Long-term performance depends on proper planning, correct construction methods, and attention to detail at every stage of the build.
In my experience, most shower failures are not caused by materials. They are caused by shortcuts, poorly constructed shower pans, or incomplete waterproofing systems. Once tile is installed, those mistakes are hidden until damage has already occurred.
When each component is installed correctly and in the proper sequence, the result is a shower that performs reliably for decades, not just a few years.
For homeowners considering professional shower remodeling, prioritizing proven construction methods and experienced installation is the most effective way to protect your investment and achieve long-lasting results.
Shower Design FAQs Homeowners Ask Before Remodeling
Is a curbless shower better than a curbed shower?
This comes up more and more during consultations, and the answer depends heavily on the home and how the shower is built. Curbless showers often get labeled as an upgrade, but they are not automatically the better choice. In slab homes especially, a traditional curbed shower is often simpler to build, less invasive, and easier to control water long term. Curbless showers can be a great option in the right situation, but they are not something we recommend blindly just because they look modern.
Do curbless showers leak more than curbed showers?
Not typically, unless something was missed during the construction phase. Curbless showers leave very little margin for error, so slope, drain placement, and waterproofing must all be done correctly. When we are brought in to evaluate failed showers, the issue almost never comes down to whether there was a curb. It is usually a shortcut taken early that did not show up until years later.
Is a curbless shower better for aging in place?
It can be, but this often surprises homeowners once we talk it through. Accessibility has more to do with how the shower is laid out than whether there is a curb at the entry. Low-profile curbs, properly placed seating, grab bars, and a handheld sprayer often provide nearly the same benefit without the added structural work a true curbless design requires. In many homes, that approach ends up being the more practical and cost-effective solution.
Is converting a bathtub to a shower a good idea?
In many Austin homes, tub-to-shower conversions are one of the most practical and popular upgrades available. They improve accessibility, make better use of space, and are often easier to maintain over time. The key is proper planning, especially drainage, waterproofing, and layout, to ensure the new shower performs reliably for years to come.
From a resale standpoint, removing a bathtub does not usually hurt home value and can often improve buyer appeal, especially in primary bathrooms. Many buyers prefer a well-built walk-in shower over a tub that rarely gets used. The main exception is homes with only one bathroom or properties targeting families with young children, where keeping at least one tub in the home is typically recommended. When the conversion is planned correctly and professionally built, it is generally viewed as an upgrade, not a liability.
Are tub-to-shower conversions more affordable than building a new shower from scratch?
In most cases, yes. When a homeowner already has a bathtub, converting that existing tub space into a shower is usually more cost-effective and far more predictable than building a new shower from scratch. The existing footprint, plumbing location, and drainage are already in place, which reduces structural unknowns. Costs can increase when a project expands beyond the tub area, such as taking space from a closet, combining a separate tub and shower into one larger shower, or relocating plumbing. Both structural changes and finish selections affect the final cost. Even then, tub-to-shower conversions usually remain easier to plan and budget for than entirely new shower builds because fewer unknowns exist during construction.
What actually makes a shower last 20 or 30 years?
Most people expect this to come down to tile or fixtures, but that is rarely the case. Long-term performance depends on what is happening underneath the surface: a properly built shower pan, a complete waterproofing system, and correct sequencing during installation. The failures we see almost never trace back to materials. They come from rushed steps that were hidden once the tile went in.
That said, homeowner upkeep also plays a role in longevity. Regular cleaning, proper ventilation, and routine maintenance help prevent moisture buildup and surface deterioration. Showers with natural stone require periodic sealing and ongoing care to maintain both appearance and performance over time.
