Walk-In Shower Installation Cape Cod Homeowners Trust

A walk-in shower installation on Cape Cod, MA is the gut-and-rebuild of an existing tub or shower bay into a curbed or curbless shower enclosure built from waterproof substrate, sloped pan, tile, and tempered glass, engineered to drain water for 25+ years without leaking into the subfloor below. WM Construction installs walk-in showers across Mid-Cape, Upper Cape, and Outer Cape towns using Schluter Kerdi-Shower bonded waterproofing membranes, RedGard liquid-applied waterproofing, or Mapei Mapelastic systems matched to the substrate and tile we're setting. We pull plumbing permits under 248 CMR and building permits under 780 CMR before demolition begins, and we install brass-bodied valves and pressure-balancing trim from Kohler, Toto, and Hansgrohe rated for the chloramine levels on Cape Cod municipal water.

We are not a national franchise booking jobs through a 1-800 line, we are a Cape Cod general contractor headquartered at 1550 Falmouth Road, Suite 26, Centerville, MA 02632. Every walk-in shower we build is permitted by a WM project manager, framed by our own carpenters, waterproofed by our tile lead before flood-testing, and signed off after a final inspection by the local building department. Approved Hanscom Air Force Base vendor since 2015.

Walk-In Shower Configurations We Build on Cape Cod

Standard Alcove Walk-In Shower (32–60" Width)

Three-wall enclosure built into the existing tub footprint, typically 32" to 60" wide by 32–36" deep, with a low-profile curb, single fixed glass panel or pivot door, and Schluter Kerdi-Shower waterproofing under tile. We rebuild the alcove framing to 16" on-center, install Kerdi-Board or 1/2" cement board, set the pre-sloped foam tray, and tile the walls 6" above showerhead height per Massachusetts plumbing code recommendations. This is the most common Cape Cod tub-removal upgrade in master and guest baths.

Corner Walk-In Shower with Two Glass Panels

L-shape or neo-angle enclosure tucked into a bathroom corner, frees up wall space for vanities or linen storage, with two tempered glass panels (often one fixed, one swing) meeting at a 90° or 135° angle. We waterproof with Kerdi membrane on Kerdi-Board, slope the pan to a single linear or center drain, and use stainless 304 hardware rated for the salt-air corrosion conditions found in coastal Cape Cod homes from Sandwich to Provincetown. Glass panels are 3/8" or 1/2" tempered with a clear EnduroShield coating to resist hard-water spotting.

Tile-to-Ceiling Frameless Walk-In Shower

Floor-to-ceiling tile with a frameless tempered-glass enclosure, the high-end Cape Cod master bath build. We frame with FSC-rated lumber, hang Kerdi-Board to the ceiling, set a custom mortar pan with linear drain at 1/4" per foot slope, and install 12x24 large-format porcelain or natural stone tiles with epoxy grout in wet zones. The frameless glass is custom-measured, tempered to ANSI Z97.1, and hung on stainless brackets through tile-and-blocking, never just into substrate. Hansgrohe rain-head and handheld combos are common in this build.

Curbless Wet Room Configuration

Aging-in-place and accessibility-driven build, eliminates the curb entirely, sloping the entire bathroom or shower zone toward a linear drain so wheelchairs and walkers can roll directly in. We frame the subfloor with a recessed pan, install a Schluter Kerdi-Line or Quick-Drain linear drain, waterproof with bonded membrane up the walls 6" beyond the wet zone, and tile with slip-resistant porcelain rated DCOF ≥ 0.42 per ANSI A137.1.

Why Cape Cod Homeowners Choose WM Construction for Walk-In Shower Installation

Schluter Kerdi-Shower Bonded Waterproofing on Every Build

We install Schluter Kerdi-Shower systems, Kerdi membrane bonded directly to substrate with unmodified thinset, Kerdi-Drain or Kerdi-Line drain assemblies, and Kerdi-Band sealing every seam, corner, and pipe penetration. The system carries a 10-year manufacturer warranty when installed per Schluter spec, which is the standard our tile leads work to. No silicone-only joints, no roofing tar, no tar paper, just bonded sheet membrane that turns the tile assembly into a sealed waterproof envelope before tile is set.

ANSI A108 Pan Slope and Flood-Tested Before Tile

Every shower pan we build is sloped to TCNA Handbook standards, minimum 1/4" per foot toward the drain per ANSI A108.01-3.6. We flood-test the pan for 24 hours before any tile is set, holding water above the threshold and checking for any drop in level. If the pan fails the flood test, we tear it out and rebuild, we do not warranty over a leaking pan. This is the single biggest reason walk-in showers fail on Cape Cod homes within the first decade.

Brass-Bodied Valves Rated for Cape Cod Water

We specify pressure-balancing or thermostatic valves from Kohler, Toto, or Hansgrohe, brass-bodied, ASSE 1016 / ASME A112.18.1 certified, and rated for the chloramine and chloride levels present on Cape Cod municipal water from Barnstable Water and Sandwich Water districts. Plastic-bodied bargain valves crack within 5 years on Cape Cod due to chloramine attack on plastic seals. We install brass.

Frameless Glass Tempered to ANSI Z97.1 and Custom-Measured On-Site

Frameless tempered glass enclosures are measured on-site after tile is set, never pre-ordered to drawing dimensions, because tile thickness and grout joints shift the opening 1/8"–1/4". We use 3/8" or 1/2" clear tempered glass certified to ANSI Z97.1, hang it on stainless 304 brackets fastened through tile into solid blocking, and seal the perimeter with neutral-cure silicone.

MA Permits Pulled and Inspected Before We Tile

We pull a building permit under 780 CMR for any walk-in shower install that touches structure or framing, and a separate plumbing permit under 248 CMR for valve and drain rough-ins. The local building inspector signs off on the rough-in before we close walls, then again after tile and trim are complete. No permit, no install, that is non-negotiable on every WM Construction job, residential or federal.

Our Walk-In Shower Installation Process on Cape Cod

1

Step 1, On-Site Design Consultation and Measure

A WM project manager visits the home, Centerville, Falmouth, Mashpee, Yarmouth, anywhere on Cape, measures the existing tub or shower bay, checks subfloor condition, locates the drain rough-in, and reviews venting and supply-line access from below. We discuss configuration (alcove, corner, tile-to-ceiling, curbless), valve brand, glass style, tile selection, and curb height. You receive a fixed-price written quote within 5 business days that includes permit fees, demolition haul-off, and final inspection.
2

Step 2, MA Permit Pull and Material Order

Once contracted, we pull the building permit under 780 CMR and the plumbing permit under 248 CMR through the local building department (Barnstable, Falmouth, Mashpee, Bourne, etc.). Permit timelines run 5–15 business days depending on town. In parallel, we order Schluter Kerdi-Shower kits, valve trim, tile, and tempered glass templates, lead times are 2–6 weeks for custom tile and 3–4 weeks for frameless glass.
3

Step 3, Demolition, Framing, and Plumbing Rough-In

We protect floors and adjacent rooms with ZipWall barriers and Ram Board, then demolish the existing tub or shower down to studs and subfloor. We replace any rotted blocking, sister joists if needed, and reframe to 16" on-center for tile backer support. A licensed Massachusetts plumber re-pipes valve and drain rough-ins to the new configuration, and the local inspector signs off before we close walls.
4

Step 4, Waterproofing, Pan Build, and Flood Test

We hang Kerdi-Board or 1/2" cement board on the walls, set the Kerdi pre-sloped foam tray (or build a mortar pan sloped 1/4" per foot to the drain), bond Kerdi membrane to all walls and corners with unmodified thinset, and seal every seam with Kerdi-Band. Pipe penetrations get Kerdi-Seal gaskets. We then flood-test the pan for 24 hours, water held above the threshold, checked at hour 12 and hour 24 for any drop. Only after the pan passes do we tile.
5

Step 5, Tile, Grout, Valve Trim, and Glass Install

Wall tile is set with modified thinset (porcelain) or unmodified thinset under Kerdi (per Schluter spec), grouted with epoxy or stain-resistant cement grout in wet zones. Valve trim, showerhead, handheld, and body sprays are installed and pressure-tested. Tempered glass is measured on-site after tile cures, fabricated, and installed 7–14 days later on stainless 304 hardware. Final building inspector walk-through closes the permit.

Walk-In Shower Installation Cost on Cape Cod, MA

Walk-in shower installation on Cape Cod, MA typically runs $12,000 to $18,000 for a standard tub-to-shower alcove conversion (32–60" wide), $18,000 to $28,000 for a tile-to-ceiling frameless build, and $28,000 to $45,000+ for a curbless wet room with linear drain, large-format tile, and high-end fixtures from Kohler, Toto, or Hansgrohe. The single biggest cost driver is tile selection and waterproofing system: a porcelain tile job over Kerdi-Shower runs roughly half the labor of a natural stone tile job over a custom mortar pan with linear drain.

Other cost factors specific to Cape Cod: subfloor repair (common in older Sandwich, Falmouth, and Yarmouth homes where prior shower leaks rotted joists), MA plumbing permit fees ($150–$400 depending on town), tempered glass enclosure ($1,800–$4,500 for frameless), and pre-1978 home lead-paint protocols where wall demolition exposes painted surfaces, WM Construction is EPA RRP Lead Safe certified, included at no extra cost.

Every WM walk-in shower install includes Schluter Kerdi-Shower waterproofing or equivalent, a flood-tested pan, brass-bodied valves, ANSI Z97.1 tempered glass, and the permit pulled in your name with the local building inspector signing off. We do not bid against discount installers using plastic valves and roll-on waterproofing, that is not the build we offer.

Marcelo and his team converted our master tub into a tile-to-ceiling walk-in shower. The Schluter waterproofing detail before tile was something I'd never seen another contractor on Cape Cod do. The frameless glass was measured after tile was set and installed perfectly. Worth every dollar.

WM did a curbless walk-in shower for my mother's bathroom in Yarmouth, wheelchair-accessible. They handled the permit, the building inspector signed off twice, and the linear drain is dead-flush with the tile. Three years later it still drains perfectly. Highly recommend.

Walk-In Shower Installation FAQs (Cape Cod, MA)

Do I need a permit for a walk-in shower installation in Massachusetts?

Yes. Any walk-in shower install that touches plumbing, framing, or electrical requires a building permit under 780 CMR and a plumbing permit under 248 CMR pulled with the local building department. WM Construction pulls every permit in our name, schedules rough-in and final inspections, and gives you the signed-off paperwork at project closeout. Permit fees on Cape Cod typically run $150–$400 depending on town.

How long does a walk-in shower installation take on Cape Cod?

Standard tub-to-walk-in conversions run 3–4 weeks from demo to final inspection. Tile-to-ceiling frameless builds run 4–5 weeks. Curbless wet rooms with linear drains and large-format tile run 5–6 weeks. Permit timelines (5–15 business days) and frameless glass lead times (7–14 days after tile cures) are the two biggest schedule drivers, we plan around both upfront so the project doesn't stall.

What waterproofing system do you use behind the tile?

Schluter Kerdi-Shower bonded sheet membrane is our default, Kerdi membrane over Kerdi-Board or 1/2" cement board, Kerdi-Drain or Kerdi-Line drain assembly, Kerdi-Band sealing every seam, and Kerdi-Seal gaskets on pipe penetrations. The system carries a 10-year warranty when installed per Schluter spec. For mid-budget jobs we use RedGard or Mapei Mapelastic liquid-applied waterproofing rolled or troweled over cement board to a minimum 30 mil dry-film thickness.

Why frameless tempered glass instead of a sliding door?

Frameless tempered glass (3/8" or 1/2" certified to ANSI Z97.1) gives the cleanest visual line and the easiest cleaning surface, no aluminum tracks to collect soap scum and mildew. Sliding doors save floor swing space and cost less, but tracks fail in 7–10 years on Cape Cod due to chloride corrosion. We measure frameless glass on-site after tile is set, never to drawing dimensions.

Can you make the shower wheelchair-accessible (curbless)?

Yes, curbless wet room configurations are one of our most-requested Cape Cod aging-in-place builds. We recess the subfloor framing, install a Schluter Kerdi-Line or Quick-Drain linear drain, slope the entire floor 1/4" per foot toward the drain, waterproof up the walls 6" beyond the wet zone, and tile with slip-resistant porcelain rated DCOF ≥ 0.42 per ANSI A137.1. Curbless builds need careful joist planning and are best designed before structural work begins, so call early in the planning.
