Walk-In Shower Installation is a full system build: framing, drainage, waterproofing, and a durable finish surface that sheds water correctly. We start by verifying subfloor flatness with a laser level, then form the pan using a pre-sloped foam tray or a mortar bed with a 1/4"-per-foot pitch toward the drain. Waterproofing is completed with a Schluter-KERDI membrane or a liquid-applied ANSI A118.10 system (checked with a wet-film gauge), and we detail corners with preformed seals to reduce failure points.
A new walk-in shower install often solves issues that show up as recurring grout cracks, soft drywall near the curb, or persistent musty odor from trapped moisture. In older homes, we frequently find undersized or poorly vented drains and improperly notched studs around the mixing valve—both can contribute to slow drainage and movement that breaks tile. We inspect the P-trap connection, confirm the drain body type (e.g., Kerdi-Drain flange vs. clamping drain), and verify that the shower valve is installed with an accessible service area, using a Moen or Delta rough-in that matches the trim you want.
Our walk-in shower installation process is structured to reduce surprises: (1) protect floors and isolate the work area with ZipWall dust barriers, (2) demolition to studs/subfloor while preserving adjacent finishes, (3) verify framing plumb with a Stabila level and reinforce where grab bars or a bench may be added later, (4) set drain location and trap alignment, (5) build pan/slope and waterproof the full wet area, (6) perform a 24-hour flood test when the assembly allows it, (7) set tile with polymer-modified thinset, and (8) grout and seal transitions with 100% silicone at changes of plane. For walk-in shower replacement projects, we also confirm the fan ventilation path to help control humidity after installation.
Materials and standards matter because water exposure is constant. We use cement backer board (e.g., USG Durock) or foam shower panels rated for wet areas, and we follow TCNA Handbook methods (such as B422/B421 assemblies depending on substrate and membrane). Tile is installed with ANSI A118.4/A118.15 mortars where specified, and we use epoxy grout (ANSI A118.3) in many applications to reduce staining and water absorption. For safety, we can integrate a textured porcelain floor tile and verify slope at the threshold to support a clean entry without compromising drainage.
Quality control is built into the details: correctly sized expansion gaps, proper drain weep protection where applicable, and precise cutting around valves and niches using a wet saw and diamond hole bits. As a reference point, industry guidance commonly targets a minimum 2% slope (about 1/4" per foot) to the drain for shower floors—critical for preventing standing water and mineral buildup. Every walk-in shower installation is finished with cleanable joints, straight layout lines, and waterproof transitions that align with manufacturer instructions and code expectations.
Des Plaines homes—especially mid-century properties near Cumberland and established neighborhoods around Prairie Lakes—often have bathrooms with aging plumbing lines and earlier tile assemblies that predate modern waterproofing standards. Our Walk-In Shower Installation work accounts for seasonal humidity swings and winter dryness that can stress framing and grout lines, so we prioritize TCNA-referenced movement joints and manufacturer-approved membranes. We also plan around local inspection expectations through the City of Des Plaines Building Division and coordinate material delivery and access for typical Chicago-metro lot layouts, ensuring the shower assembly is built to manage water reliably in everyday Des Plaines use.

Walk-In Shower Installation pricing in Des Plaines typically depends on four main variables: (1) size and layout (standard alcove vs. custom footprint), (2) waterproofing system and pan type (foam tray vs. mortar bed), (3) finish choices (porcelain tile, niche, bench, glass, and fixtures), and (4) plumbing changes (moving the drain, replacing the valve, or correcting venting). Costs usually increase when subfloor repair is needed, when the drain must be relocated, or when multiple waterproofing transitions are required around niches and curbless entries. The most accurate way to price a walk-in shower install is to measure the footprint, verify framing/subfloor condition, and confirm whether the existing drain and valve locations can be reused.
Most Walk-In Shower Installation projects take about 3–7 working days, depending on demolition scope, waterproofing method, tile complexity, and drying/curing time. A straightforward replacement where the drain and valve stay in place often lands on the shorter end. Timelines extend when the drain is moved, a mortar bed is used (additional cure time), a flood test is scheduled, or custom tile patterns, niches, and benches are added.
In Des Plaines, a permit is commonly required when the project includes plumbing alterations (moving a drain, replacing a valve, changing supply lines) or electrical work (new circuits, fan changes, or receptacle modifications near the bath). If your walk-in shower installation is a like-for-like replacement without changing plumbing locations, permit needs can vary. Requirements are typically administered through the City of Des Plaines Building Division, and installations should follow the Illinois Plumbing Code and applicable sections of the local building code. We can review the scope with you and identify when permitting is likely necessary.
Common signs include: persistent grout cracking at wall-to-floor transitions; soft or swollen baseboards outside the shower; mildew odor that returns quickly after cleaning; loose or hollow-sounding tile indicating substrate movement; staining around the drain or at the curb/threshold; and recurring caulk failure at corners. If you see water marks on the ceiling below the bathroom, experience slow drainage despite snaking, or notice the shower floor holds puddles after use, those are strong indicators the current assembly may be failing and a new walk-in shower install is the safer long-term fix.
