Everything You Need to Know Before Building a Custom Tile Shower

A complete planning guide from Comfort Flooring — custom tile showers designed and installed across Michiana and Southern Michigan.

Ask anyone who has remodeled a bathroom in Granger, Mishawaka, or Goshen what made the project feel custom, and the answer is almost always the shower. A tiled shower is the one part of a home where craft, waterproofing science, and design all meet in a six-by-four-foot space — and it is the part our team has been building for more than 27 years, from classic tub-to-shower conversions in mid-century South Bend homes to curbless, spa-style walk-ins in new Granger builds.

This guide walks the full journey: choosing a layout, sizing the features (niches, benches, glass), understanding why tile size on a shower floor is a physics decision rather than a style one, what is hiding behind the tile that makes the whole thing work, and how the porcelain-ceramic-glass decision plays zone by zone. Each interactive tool below is one of the conversations we have during a real design consultation — try them in any order, then bring your results to either showroom.

Step One: Choose the Layout Your Bathroom Actually Wants

Most Michiana bathrooms fall into one of three shower stories. The tub-to-shower conversion reclaims the footprint of a rarely-used bathtub — common in homes from the 1960s through the 1990s across South Bend and Osceola — and turns it into a generous walk-in. The corner shower fits hall baths and tighter primary baths, using glass on two sides to keep a small room feeling open. And the curbless walk-in removes the step entirely: one continuous floor plane from bathroom into shower, a clean modern look that also happens to be the smartest aging-in-place decision a homeowner can make — a real consideration if you plan to stay in your home for the long haul.

The Physics Lesson Hiding in Your Shower Floor

Here is the planning detail that surprises almost everyone: the tile you love for the walls is often the wrong tile for the shower floor — not because of style, but because of slope. Every shower pan is built with a deliberate pitch toward the drain so water leaves instead of pooling. A flat, rigid 12-inch tile cannot bend to follow that compound slope; small tiles can, because every grout joint acts like a hinge. Smaller floor tile also means more grout lines underfoot, and grout is grip — a real safety consideration in a busy family bathroom.

Porcelain, Ceramic, or Glass: A Zone-by-Zone Decision

The second most common shower question is material. Our tile guide explains the core difference: porcelain is fired at higher temperatures than ceramic, making it denser, more water-resistant, and more durable, often with color running through the full tile body — while ceramic offers vivid glazes at a friendlier price and is easier to work with. In a shower, that difference is not academic; it maps to zones.

X-Ray Vision: What Makes a Tile Shower Actually Waterproof

Here is the truth every tile professional knows and every homeowner should: tile and grout are not the waterproofing. They are the armor and the finish. The waterproofing is the system behind them — membranes and properly prepared backer surfaces that direct every drop toward the drain even after years of steam and showers. It is the part of the project you will never see again after install week, and it is the part that decides whether your shower is still perfect in fifteen years. Drag the X-ray slider to peel back the tile and look at the system underneath.

Niches, Benches, and the Ergonomics of a Daily Ritual

The difference between a shower you tolerate and one you love is usually ergonomic, not aesthetic. A recessed niche replaces the wire caddy hanging off the showerhead with storage tiled into the wall itself — sized for your actual bottles, placed where reaching is natural rather than where a stud happened to be, and often doubled: one tall niche for daily products, one lower for kids or bath items. Because niches are built into the waterproofing system, they are a plan-ahead feature, not a retrofit — one more reason the design consultation comes first.

The built-in bench earns its space three ways: a comfortable seat for a long steam, a stable ledge that makes shaving safer than balancing on one foot, and a future-proofing feature that quietly supports aging in place alongside a curbless entry. Benches change the pan layout and the waterproofing details beneath them, so like niches, they belong in the first sketch. Both features cost remarkably little to include during construction compared to what they add every single day after — which is why they appear in our finishing-touches step rather than the upgrade sheet.

Tub Out, Shower In? Think Household, Not Trend

The tub-to-shower conversion is our most requested layout for good reason — most adults shower — but the decision deserves one household-level question: does anyone bathe? Families with young children, dedicated bath-lovers, and households thinking about resale often keep at least one tub in the home, converting the primary or hall bath while preserving a tub elsewhere. If the tub stays, it does not have to stay dated: custom tub surrounds are part of our tile work too, bringing the same materials and waterproofing discipline to the bathing wall. And if the whole bathroom is in play, coordinating the shower tile, floor, and a new tile or waterproof plank floor in one project keeps the room coherent and the disruption singular.

Grout, Steam, and the Maintenance Truth

Tile maintenance is really grout maintenance, so choose grout strategically. Mid-tone grout close to the tile color is the forgiving path — bright white joints on a shower floor announce every season of real life, while a coordinated gray or greige stays handsome with normal care. Grout color also changes the design: matching grout makes a wall read as a single surface; contrasting grout turns the layout itself into the pattern. It is a small sample-board decision with a decade of consequences, and it is part of every material-selection session in our showrooms.

The other maintenance hero is air. Michiana summers are humid, and a bathroom that cannot exhaust steam ages faster — squeegee the glass, run the fan, and the shower you build with us stays showroom-grade for years with nothing more than routine cleaning. The waterproofing system underneath, meanwhile, is doing the structural work invisibly; that is the whole point of building it right once.

Glass Doors: The Detail That Finishes the Room

The glass is what your eye meets first, and it is a genuine custom item: we measure and install both framed enclosures — economical, forgiving, classic — and frameless glass, the clean-edged look that makes tile work feel like a showroom display. Frameless glass loves precise tile work (edges and plumb lines show everything), which is one more reason glass and tile should come from one coordinated project rather than two separate contractors pointing at each other. Ours come from one team, measured to fit your exact opening.

The Same Craft, Elsewhere in the House

The skills that make a shower watertight and beautiful — layout, cuts, waterproofing discipline, clean grout lines — travel well. We bring the same tile craft to kitchen backsplashes, where a custom design adds color and easy-to-clean protection behind the range; to custom tub surrounds, for the bath that stays; and to tiled fireplaces, the living room’s answer to an accent wall. Homeowners often discover this mid-project: the shower comes out so well that the backsplash gets added to the plan. If a larger refresh is on your horizon, mention it at the consultation — sequencing tile work together is more efficient than booking it twice, and financing can spread the combined project into manageable payments, subject to credit approval.

It is also worth saying plainly why a flooring and design center builds showers at all: tile is tile. The store that helps Michiana homeowners pick porcelain for an entryway and natural stone for a hearth keeps that same materials knowledge an arm’s reach from your shower wall — plus a showroom where you can stand in front of full displays instead of squinting at three-inch chips. Between the porcelain, ceramic, glass, and natural stone collections, the palette for your project is genuinely deep.

How the Project Actually Runs

Our shower process follows four steps, and they match the tools you just used. First, the design consultation: goals, budget, and style — bring photos of your bathroom, inspiration saved from Houzz or Pinterest, and even a paint chip or towel you love; that is genuinely what our consultants ask for. Second, material selection: tile, grout color, and glass options from the showroom wall. Third, professional installation by licensed and insured installers — demolition, waterproofing system, pan, tile, and glass with precision. Fourth, finishing touches: niches, benches, and accent details that make it yours. Bathrooms are also where floors meet showers, so many projects pair the new shower with waterproof flooring or tile for the rest of the room — one crew, one timeline, via our flooring installation service.

While you plan the budget, remember two things: financing options let you buy now and pay over time (subject to credit approval), and beyond showers we also build kitchen backsplashes, custom tub surrounds, and tiled fireplaces — if the project grows, the same team grows with it.

Small Bathrooms, Big Results

Most of the showers we build are not in sprawling primary suites — they are in the five-by-eight hall baths that northern Indiana builders repeated for decades. Compact spaces reward custom work disproportionately. Glass instead of a curtain instantly returns visual square footage; a corner layout with a glass return keeps the room breathing; light wall tile run high lifts the ceiling; and a single vertical accent stripe draws the eye up rather than across. Even the niche strategy changes: in a tight shower, recessed storage is not a luxury, it is the difference between a clean enclosure and a cluttered one. If your bathroom feels too small to bother customizing, it is usually the one with the most to gain — bring its measurements to the showroom and let the design team prove it.

A Realistic Timeline, Stage by Stage

Custom work runs on a different clock than dropping in a prefab unit, and knowing the stages keeps the project relaxed. Design consultation and material selection happen at your pace — some homeowners decide in a week, some savor a month. Once materials arrive, demolition opens the space, and the unseen stages follow in order: pan construction, waterproofing system, then tile setting, which is craftsmanship-paced by definition — layout, cuts, and detail work around niches and benches are where the hours go. Grout follows tile, cure times follow grout, and the glass enclosure is measured against the finished tile so it fits your shower rather than a theoretical one, then fabricated and installed as the finale. Stack those stages and you understand why a proper custom shower is measured in weeks, not days — and why every one of those weeks shows in the result. Your consultation produces the real schedule for your bathroom before demolition begins, so the only surprises left are good ones.
