When clients contact Infinity Kitchen and Bath about a new shower, the conversation almost always starts the same way: "I want tile." It makes sense. Tile is what most people grew up with, and a beautiful custom tile shower is genuinely stunning when it is done right. But over the last decade, solid-surface "groutless" shower wall panels have become a serious alternative — and for a growing number of Prescott homeowners, a smarter one.
This is not a knock on tile. We install a lot of tile showers, and we are proud of every one of them. But we also know from years of working in Prescott homes that grout is the Achilles' heel of most tile showers, and the reality of living with tile is often more demanding than homeowners expect. Groutless panels solve that problem in a way that tile simply cannot.
This guide gives you an honest, side-by-side look at both options — what each one is, how they compare on the factors that matter most, what they cost in Prescott right now, and which type of homeowner is the best fit for each. By the time you finish reading, you will have enough information to make a confident, well-informed decision for your bathroom.
A groutless shower uses large-format solid-surface wall panels in place of individual tiles. These panels are made from engineered acrylic or composite materials and are manufactured to mimic the look of stone, marble, concrete, or large-format tile — without any grout lines between them.
Infinity Kitchen and Bath is a licensed Sentrel dealer. Sentrel is one of the leading solid-surface shower panel brands available through professional remodelers, offering panels in a wide range of finishes and patterns including marble-look, slate, linen, and solid colors. Panels typically come in 4×8 or 5×10 foot sheets, which means an entire shower wall can be covered with a single panel or two panels with a single hidden seam — rather than dozens or hundreds of individual tiles with grout joints between each one.
Installation is significantly faster than tile because there is no setting mortar, no tile layout, and no cure time. The panels are bonded and sealed directly to a prepared substrate, and the seams are treated with a color-matched sealant that is nearly invisible once finished. The result looks like a high-end stone or large-format tile shower, but it has no grout to clean, seal, or repair — ever.

A tile shower uses individual ceramic, porcelain, or natural stone tiles set in thinset mortar on a waterproofed substrate, with grout filling the joints between each tile. Tile gives you virtually unlimited creative flexibility — you can choose any size, shape, color, finish, or layout pattern you want. Subway tile, large-format 24×24 porcelain, mosaic glass, herringbone natural stone, wood-look plank tile — all of it is possible, and the design combinations are essentially endless.
The critical variable in any tile shower is waterproofing. Tile itself does not keep water out — the waterproofing membrane underneath the tile does. At Infinity, we use Schluter Systems products — specifically Kerdi membrane or Kerdi-Board — to create a fully bonded waterproof barrier behind every tile shower we install. This approach ensures that moisture never reaches the studs or the framing behind the wall, regardless of what happens to the grout over time.
A properly waterproofed, professionally installed tile shower is a long-lasting, beautiful addition to any home. The challenge is maintenance — specifically, the grout. We will come back to that in detail below.
See our tile shower installation page for more on how we approach custom tile work.
Here is how the two options stack up across the factors that matter most to Prescott homeowners:
| Factor | Groutless (Sentrel Panels) | Tile (Porcelain / Stone) |
|---|---|---|
| Installation time | 1–2 days | 5–10 days (including cure time) |
| Cost installed | $3,500–$6,500 | $4,500–$9,000+ |
| Maintenance | Zero — no grout to seal or scrub | Grout sealing 1–2x/year; regular scrubbing required |
| Longevity | 20–30 years | 15–25 years (tile lasts; grout degrades) |
| Customization | Limited to available patterns and colors | Unlimited — every size, color, texture, and layout |
| Repairability | Difficult to repair a single damaged panel | Individual tile replacement possible |
| Mold risk | Minimal — no grout joints to harbor growth | Higher — grout is porous and retains moisture |
| Water leak risk | Low — fewer seams, non-porous surface | Higher without proper waterproofing behind tile |
Grout is a cement-based material. It is porous by nature, which means it absorbs water, soap residue, body oils, mildew spores, and mineral deposits with every shower. Over time, those absorbed materials stain and discolor the grout, and no amount of scrubbing will fully restore it once the staining is deep enough. This is not a product defect or an installation error — it is simply what cement-based grout does when it is exposed to a wet environment every day.
Sealing the grout slows the process, but it does not stop it. Most grout sealers need to be reapplied once or twice a year to remain effective, and even diligent homeowners often miss this step. By years three to five, many tile showers start to show significant grout discoloration, and by year eight to ten, a significant percentage require either a full regrout or a complete shower tear-out and rebuild.
In Prescott specifically, the problem is compounded by water quality. Yavapai County water has high mineral content — what most people call "hard water." Mineral scale from hard water deposits on grout surfaces more aggressively than it does in areas with soft water, and it accelerates the discoloration and degradation of grout joints. Prescott homeowners often find that their grout looks good for a shorter window than the manufacturer's maintenance schedule would suggest.
Perhaps most importantly, the biggest driver of full bathroom renovation projects is water damage behind shower walls — and failed grout is the leading cause. When grout cracks, shrinks, or degrades enough to allow water infiltration, moisture works its way behind the tile and into the wall cavity. By the time the damage is visible on the outside, the framing and substrate are often already compromised. Groutless panels eliminate grout joints entirely, which means they eliminate the primary failure point in most shower installations.
Groutless shower panels are the right choice for a specific type of homeowner — and if you fall into one of these categories, the decision is usually straightforward.
Tile is the right answer in certain situations, and when it is the right answer, there is nothing better. Here is when we recommend tile:
Pricing in Prescott varies based on shower size, material selection, plumbing scope, and whether the project involves demo and substrate repair. The figures below represent typical installed costs for a standard remodel with no major surprises — they include labor, materials, and standard trim. They do not include plumbing fixture upgrades, custom niches, or structural repairs if water damage is found.
| Shower Size | Groutless (Sentrel) | Tile (Porcelain, Schluter WP) |
|---|---|---|
| Standard 3×5 ft shower | $3,500–$5,000 | $4,500–$7,000 |
| Walk-in 4×6 ft shower | $5,000–$6,500 | $6,500–$9,000+ |
A few cost factors worth noting for Prescott specifically: labor costs in the Quad Cities area have increased meaningfully over the past few years, and material lead times can affect project scheduling. Groutless panels generally have more predictable material availability than specialty tile, which can sometimes run into lead-time delays when ordered from out-of-state suppliers. If your project timeline is firm, that is another practical point in favor of groutless.

We offer both groutless and tile showers, and we genuinely do not have a preference for one over the other from a business standpoint. We want to install the right product for each client's specific situation — not the one that is easiest to sell.
Our honest assessment, based on years of working in Prescott homes, is this: if you do not have a strong preference for a specific tile aesthetic, and you are honest with yourself about how much time and effort you want to invest in shower maintenance, groutless panels are often the smarter choice. They perform well in Prescott's hard water conditions, they hold up over time without the grout degradation cycle, and the lower installation cost combined with zero ongoing maintenance cost gives them a favorable total cost of ownership over a 10-to-15 year horizon.
If you want a truly custom tile design — a specific stone, a unique layout, a master bath that makes a visual statement — tile is absolutely the way to go, and we will install it correctly with proper Schluter waterproofing so it performs as long as possible.
The best way to decide is to see both options in person. We are happy to bring Sentrel panel samples and tile samples to your home consultation so you can see the actual material, feel the surface, and compare them side by side in your own bathroom. That is how most of our clients make their final decision, and it works better than any photo on a website.
For most homeowners, yes — especially from a few feet away. Modern Sentrel panels are manufactured to closely replicate the look of stone and large-format tile, and many guests in a finished bathroom would not immediately identify the walls as panels rather than tile. The difference becomes more apparent up close, where a skilled eye can distinguish panel seams from grout lines. If your priority is achieving a high-end look with minimal maintenance, groutless panels deliver that. If you want a truly one-of-a-kind tile installation with custom layout and material choices, tile will always have the edge on pure aesthetics.
Not typically. In Prescott, a groutless panel shower tends to run $1,000 to $2,500 less than a comparable tile shower on the initial installation — largely because tile labor is more intensive and tile projects require longer timelines with cure time factored in. When you also account for ongoing maintenance costs (annual grout sealing, grout restoration products, and potential regrout or tile repairs over a 10-to-15 year period), the total cost difference often widens further in favor of groutless.
Yes. Sentrel panels are engineered specifically for wet environments and are rated for 20 to 30 years of normal residential use. The surface is non-porous, which means it does not absorb water, soap, or minerals the way grout does. The panels resist chipping, cracking, and surface staining under normal conditions. Like any surface, they can be scratched by abrasive cleaners — but with standard care, they hold up extremely well over time.
In most cases, no. Solid-surface shower panels are designed for wall applications. Shower floors require a textured, slip-resistant surface that can handle standing loads, foot traffic, and water drainage — requirements that flat wall panels do not meet. Shower floors in groutless shower builds are typically done in a matching or complementary tile or in a prefabricated shower base. We will walk you through the flooring options during your consultation.
Cleaning a Sentrel groutless shower is straightforward: wipe down the panels with a soft cloth or non-abrasive sponge and a mild bathroom cleaner after use. Avoid abrasive scrubbing pads or harsh chemical cleaners, which can dull the surface over time. For hard water mineral buildup — which is a real consideration in Prescott — a diluted white vinegar solution works well and will not damage the panels. That is genuinely all the maintenance required. No sealing, no grout scrubbing, no annual treatments.
