Showers & Wet Areas

The 1990s fiberglass insert that has yellowed in the band where the showerhead runs every morning and is finally ready to come out. The down-to-the-studs master remodel where the new walk-in shower has to go in curbless because the homeowner is planning to age in place. The pinhole leak at the shower-pan-to-wall seam that has been bothering the bedroom ceiling below it for two winters and a leak detector pinned to the back-left corner. The recessed tile niche the previous owner cut into a wet wall without waterproofing, that has been weeping at the lower lip ever since. Showers and wet areas is the trade for the entire shower envelope — custom tile builds in five material categories, curbless walk-ins, full Schluter or Wedi sheet-membrane waterproofing on every install, recessed niches and benches that wrap into the membrane assembly, tub-surround tile, steam-shower-ready tile prep, and leak diagnosis and repair on existing assemblies. Handis self-performs every tile-trade step end to end — substrate prep, mortar or prefabricated pan, full sheet-membrane waterproofing, every tile, every seam, every grout joint. The few regulated handoffs (a new in-wall mixer on a custom build, a steam-shower generator) sub to a licensed Washington L&I plumber or electrician. From $500 for a small wet-zone caulk and waterproofing repair up to $18,000 for a custom natural-stone walk-in shower with a curbless pan and a frameless glass enclosure.

What Showers & Wet Areas Covers

Showers and wet areas is the trade for the residential shower envelope — every surface inside the shower, every membrane behind the tile, every seam where the wet wall meets the pan, and every penetration through the waterproofing for a niche, a bench, a mixer, or a drain. Seven service families, each with its own scope, price floor, and prep sequence. Handis self-performs every tile-trade and membrane step on every project: substrate inspection, framing checks, full Schluter KERDI or Wedi sheet-membrane waterproofing assembly, mortar or prefabricated pan, every tile, every grout joint, and every seam-seal. The few regulated handoffs (a new in-wall mixer rough-in on a from-scratch shower build, a steam-shower generator and its 240-volt circuit) sub to a licensed Washington L&I plumber or electrician with the line item named on every quote.

Custom Tile Shower

From-scratch custom tile showers in five material categories — porcelain (versatile, low-maintenance, the most common choice), large-format (clean grout lines, fewer joints, modern look), natural stone and marble (premium, requires special thinset and seal), subway (timeless, budget-conscious, traditional 3x6 layout), and mosaic accent (cost-effective premium look as an accent strip or full wall). Full Schluter KERDI or Wedi sheet-membrane waterproofing on every build. Niches, benches, and curb integration. Five variants live on dedicated pages below. From $5,000 for a subway-tile build up to $18,000 for a natural-stone walk-in.

Custom Tile Shower — porcelain, large-format, stone, subway, mosaic

Curbless / Walk-In Shower

Curbless walk-in showers with a mortar-bed pan sloped to a linear drain, full Schluter or Wedi sheet-membrane waterproofing tied into the surrounding bathroom floor, large-format porcelain or natural-stone walls, and a frameless glass enclosure. The aging-in-place and accessibility-forward shower choice — no curb to step over, wheelchair-rollover access where the bathroom plan supports it, the same waterproofing rigor as a curbed shower (curbless is harder to waterproof, not easier). From $8,000 for a single-wall walk-in up to $16,000 for a three-wall curbless with bench and stone walls.

Shower Pan & Waterproofing (Schluter KERDI / Wedi)

Standalone shower pan and waterproofing assembly — the part of the shower that lives under the tile. Schluter KERDI orange polypropylene-fleece sheet bonded with unmodified thinset and KERDI-BAND sealed seams; Wedi closed-cell extruded-polystyrene panels with Wedi 320 sealant on every seam; equivalent sheet-membrane systems (Hydro Ban, Mapelastic AquaDefense for crack isolation). Mortar-bed pan or pre-formed Schluter KERDI tray. Pan-to-wall seam, curb wrap, niche wrap, bench wrap, valve flashing, drain assembly. From $1,500 for a small pan rebuild up to $6,500 for a curbless mortar pan and full three-wall membrane wrap.

Shower Niche & Bench

Recessed tile niches and built-in benches with full membrane wrap — the storage and seating that gets cut into the shower assembly without compromising the waterproofing. Pre-formed Schluter KERDI-BOARD niche and bench panels foamed in place and seam-sealed, or a framed-and-membraned niche built in stud bay with a full KERDI or Wedi wrap. Brushed-nickel, chrome, matte-black, or matched-tile bullnose trim at the edges. Sloped niche floor for water shedding. From $850 for a single small niche on an existing shower wall up to $3,500 for a multi-niche and bench combination on a new build.

Shower Niche & Bench — recessed niches, built-in benches, KERDI-BOARD pre-form, full membrane wrap

Tub-Surround Tile

Tile on the wall surfaces around an alcove tub or a drop-in tub — three-wall surrounds on alcove tubs, two- or three-wall configurations on drop-ins, custom heights from standard 60-inch surround through ceiling-height. Cement-board or KERDI-BOARD substrate, full Schluter or Wedi sheet-membrane waterproofing on every wet wall, accent strips and niches as scope allows. From $4,500 for a standard three-wall surround on an existing alcove up to $10,000 for a ceiling-height drop-in surround with niche and accent banding.

Steam-Shower-Ready Tile

Tile assembly prepared for a steam-shower install — sloped ceiling for steam condensation runoff (1/2 inch per foot to the wall), full Schluter KERDI or Wedi sheet-membrane waterproofing on the ceiling as well as the walls and the pan, vapor-tight sealant on every penetration, and tile cut and laid for the higher humidity and condensation cycle of a steam environment. Handis does the tile, the membrane, the ceiling slope, and the seal-out. The steam generator itself and its 240-volt circuit sub to a licensed Washington L&I plumber and electrician on a paired adjacent-leaf service. From $7,500 for a standard steam-ready prep up to $14,000 for a custom large-format steam-ready build.

Shower Leak Diagnosis & Repair

Active leak diagnosis on an existing shower assembly — moisture mapping with a calibrated pin-and-pinless meter, isolation by source (pan-to-wall seam, valve flashing, drain assembly, niche lower lip, grout failure, membrane puncture), and repair scoped to the failure rather than to a default re-tile. Targeted demo to the affected area only when the failure source allows, full pan rebuild when the pan or pan-to-wall membrane has failed end to end. From $750 for a small grout-line repair after diagnosis up to $5,500 for a pan rebuild with new KERDI wrap and re-tile of the lower 24 inches.

Why Seattle Homeowners Book Handis for Showers & Wet Areas

Most of the failed showers we are asked to repair started with one of two mistakes. Mistake one — cement board treated as waterproofing, no sheet membrane, water tracking into the wood framing for years before the bedroom-ceiling stain appears. Mistake two — a niche cut into a wet wall without wrapping the membrane around the recess, weeping at the lower lip ever since. Both mistakes are invisible behind a tile face that looks fine for the first ten years. Handis builds every shower with a real sheet membrane (Schluter KERDI bonded with unmodified thinset, Wedi panels seam-sealed with Wedi 320, or an equivalent) and wraps every niche, every bench, every penetration, and every pan-to-wall seam into the membrane assembly. You see the membrane assembly before any tile goes over it. That is what makes a shower last 30 years instead of 12.

Full Schluter KERDI or Wedi sheet-membrane waterproofing on every shower

Cement board is a substrate, not a membrane. Every Handis shower build gets a real sheet-membrane waterproofing system bonded to the substrate before any tile goes up — Schluter KERDI orange polypropylene-fleece sheet with KERDI-BAND on every seam and inside corner, Wedi closed-cell extruded-polystyrene panels with Wedi 320 sealant on every joint, or an equivalent. You see the membrane assembly before the tile install starts.

Every penetration wrapped into the membrane

Recessed niche back walls and floors wrapped in KERDI or built from KERDI-BOARD pre-form. Built-in benches wrapped on every face. Curb wrapped on three sides (top, inside, outside). Pan-to-wall seam sealed with a continuous KERDI-BAND inside-corner. Mixer and showerhead penetrations sealed with KERDI-SEAL-PS flanges. Drain assembly fitted to the membrane with the manufacturer-spec bonding flange (Schluter KERDI-DRAIN, Wedi Fundo, Laticrete Hydro Ban Bonding Flange). Every penetration is a potential leak path; every penetration gets the right membrane detail.

Mortar-bed pan or KERDI-BOARD pre-formed tray, sloped 1/4 inch per foot

Curbed showers get a mortar-bed pan with a sloped pre-pan over a vapor-barrier layer, a PVC liner, and a deck-mud topping with the slope built in (the modern alternative is a Schluter KERDI-SHOWER-T pre-formed tray bonded to the subfloor and KERDI'd over the top). Curbless showers get a recessed mortar pan with the slope cut into the deck mud below the surrounding bathroom floor level. Either way the slope is 1/4 inch per foot to the drain — verified with a 4-foot level before the membrane wraps over.

Substrate inspection before any membrane goes up

Studs checked for plumb and rot. Subfloor checked for soft spots and slope. Existing wall panels demoed to bare stud on every full custom build to confirm the framing is sound before the cement-board or KERDI-BOARD goes up. Hidden rot from a previously leaking shower routes to framing repair before the new assembly bonds in — there is no way to waterproof over a soft sill plate or a delaminated subfloor and expect a 30-year install.

Honest licensed-trade handoff, named on the quote

The few regulated handoffs in a shower build — a new in-wall mixer or shower valve rough-in on a from-scratch custom shower, a steam-shower generator and its 240-volt circuit — sub to a licensed Washington L&I plumber or electrician. Their hours and their portion of the cost are named line by line on the quote. Permits are pulled by the appropriate licensed party. Handis runs the project and self-performs every tile-trade and membrane step.

FAQ

Frequently Asked Questions

Common questions about Handis shower and wet-area work — waterproofing, custom builds, curbless, niches, leak diagnosis, and pricing.

How much does a shower or wet-area project cost?
A small shower leak diagnosis and caulk repair starts at $500. A single recessed niche add-on starts at $850. A pan-only rebuild on an existing shower starts at $1,500. A standard three-wall tub-surround tile install starts at $4,500. A custom tile shower starts at $5,000 (subway floor) and runs to $18,000 (natural-stone walk-in at the top of the range). A steam-shower-ready tile prep starts at $7,500. A curbless walk-in shower starts at $8,000. You get a written estimate before any work begins, with the licensed-plumber or licensed-electrician portion named line by line on projects with a regulated handoff.
Does Handis do the waterproofing or sub it out?
Handis self-performs the waterproofing on every shower and wet-area build. We install Schluter KERDI orange polypropylene-fleece sheet bonded to cement-board or drywall substrate with unmodified thinset, with KERDI-BAND sealing every seam and inside corner. Or Wedi closed-cell extruded-polystyrene panels with Wedi 320 sealant on every joint. Or an equivalent residential-grade sheet membrane (Hydro Ban, RedGard liquid for small repair work). We do not treat cement board as waterproofing — cement board is a substrate, the membrane goes over it — and that distinction is the single root cause of most fifteen-year shower failures we are called to repair.
Do you handle the plumbing on a custom shower build?
Handis self-performs the demo, framing, substrate prep, membrane, pan, tile, and grout — every tile-trade step on the project. The in-wall plumbing rough-in on a from-scratch custom shower (new mixer, new shower valve, new drain location) subs to a licensed Washington L&I plumber. The plumber's hours and their portion of the cost are named line by line on the quote. On a re-tile project where the existing valve and drain stay in place, no plumbing sub is needed and Handis handles the project Handis-only.
What is the difference between KERDI and Wedi waterproofing?
Both are residential-grade sheet-membrane waterproofing systems for tile showers, and either one installed correctly is a 30-year solution. Schluter KERDI is a thin orange polypropylene-fleece sheet bonded to cement-board or drywall substrate with unmodified thinset; KERDI-BAND seals the seams and inside corners. Wedi is a closed-cell extruded-polystyrene board that combines the substrate and the waterproofing in one panel; Wedi 320 sealant goes on every seam. KERDI is the more common choice on standard alcove and walk-in showers where the substrate is already prepped. Wedi is the more common choice on curbless installs and on situations where the substrate has to be lightweight and direct-bondable. We use both and we recommend the right one for the build on the booking call.
Can you do a curbless walk-in shower in any bathroom?
Most bathrooms, yes — with two structural caveats. Curbless requires the shower pan to sit recessed below the surrounding bathroom floor level so the slope to the drain can be built in without a curb to step over. On a slab-on-grade bathroom this is a saw-cut and a deck-mud recess. On a wood-joist bathroom this requires either dropping the shower joists or building the surrounding floor up to match — and both add cost and time. We confirm the structural picture on the booking call and the on-site measurement before quoting. A standard curbed walk-in is the right choice when the structural cost of curbless is out of proportion to the design value.
Can I add a niche or bench to my existing shower without a full re-tile?
Sometimes — depends on the tile layout, the membrane condition, and what the cut into the wet wall reveals. A single small niche cut into an existing shower wall is feasible when the surrounding tile field is intact and the existing waterproofing assembly can be tied into the new niche wrap (or the niche is built far enough into the wall that we are bonding to fresh substrate). A bench add-on usually requires more re-tile because the bench has to wrap into the corner where the walls meet the pan. We assess on the booking call and tell you on arrival what the cut reveals before any irreversible demo starts.
How do you diagnose a shower leak?
We start with a calibrated moisture meter (pin and pinless modes) on the affected wall or ceiling to map the moisture pattern and isolate the source quadrant. Then a low-flow water test against suspect locations one at a time — pan-to-wall seam at each corner, valve flashing, drain assembly, niche lower lip, suspect grout lines — watching for moisture readings to spike on the meter. Once the source is isolated, the scope of repair is determined by the failure mode — a small grout-line repair when the failure is surface-only, a targeted membrane repair when the failure is at a single seam, a full pan rebuild when the pan or pan-to-wall membrane has failed end to end.
How long does a custom shower build take?
Six to ten working days on a curbed custom shower, depending on the pan style (mortar bed vs Schluter KERDI-SHOWER-T pre-formed tray) and the tile-format complexity (subway is faster than mosaic, porcelain is faster than natural stone). Eight to twelve working days on a curbless walk-in (the recessed pan adds time). Add one to two days for any custom-glass enclosure lead time on the back end. The schedule drivers are the mortar-pan cure (24 to 48 hours before membrane), the thinset cure between tile setting and grouting (24 hours), the grout cure before sealing (24 to 72 hours), and any sheet-membrane cure on the waterproofing assembly. We sequence the work so the bathroom is offline for a known number of days and you see the calendar up front.
Do I need a permit for a shower build or pan rebuild?
Re-tile and regrout work on existing showers, niche add-ons that do not move plumbing, pan rebuilds that stay within the existing shower footprint, and tub-surround tile work do not require a permit on their own. Permits are required for any new in-wall plumbing supply or drain (new mixer rough-in, new drain location, tub-to-shower conversion), new electrical circuits (steam-shower generator, heated mat circuit), and any structural framing change. The licensed Washington L&I sub pulls the permit for their portion of the work as the responsible licensed party. Handis handles the coordination but does not pull plumbing or electrical permits ourselves.
Is the work guaranteed?
Yes. Handis carries general liability and workers' compensation; every technician has cleared a background screening before the first job. Our one-year project warranty covers tile setting, grout, sealer, waterproofing membrane assembly, mortar pan, and niche and bench wraps — if a grout joint fails, a tile cracks, a membrane leak develops at a seam we sealed, or the sealer wears off prematurely inside a year because of our workmanship or prep, we come back and fix it at no charge. The licensed-sub portion on projects with a plumber or electrician carries its own Washington L&I-trade warranty, also named on the quote so you know whom to call for what.
