Shower Niche & Bench
Handis frames and builds the recessed shower niche and the built-in tile bench that turn a wet-area enclosure from a place you stand into a place you can actually use — from $700 for a single standard niche in a stud-bay-spaced box up to $2,000 for a full corner-bench-and-niche combo coordinated to the wall tile. The shampoo bottles lined up on the shower-pan curb that knock over every time anyone moves. The plastic over-the-showerhead caddy that has stained the tile under it for three years. The two-by-six built-in box-store niche kit with the visible seam at the bullnose. A purpose-framed niche set into the stud bay, built with KERDI-Board, seamed with KERDI-Band, tied into the wall membrane, and tiled to coordinate with the surrounding pattern is what a real shower niche looks like — and a built-in bench is the same construction laid flat. Hardwired niche-light fixtures or LED strip wiring routes to a licensed Washington L&I electrician as a coordinated subcontract.

What Does a Shower Niche & Bench Build Include?
A shower-niche and bench build is the recessed-storage-and-seating scope inside a tile shower — covering layout and stud-bay measurement, framing modifications where the niche has to cross a stud (cross-blocking and sister-stud framing to keep wall load intact), KERDI-Board panel cuts for the niche box or bench sides, KERDI-Band seam tape at every inside corner of the niche or bench, tie-in to the surrounding wall membrane and pan, and tile finish coordinated with the surrounding wall pattern. The shelf in a niche (single or double-shelf layouts) is a tempered-glass piece on stainless clips or a tiled-over edge built into the framing. The bench top is sloped one-quarter inch per foot toward the open shower side to shed standing water. From $700 for a single standard niche up to $2,000 for a corner-bench-and-niche combo. Hardwired niche-light wiring routes to a licensed Washington L&I electrician as a coordinated subcontract.
Layout — Standard Stud-Bay or Custom Size
Standard shower niches sit between two studs (14-and-a-half-inch interior width on standard 16-inch-on-center framing) with a height between 12 inches (single-shelf) and 24 inches (double-shelf). That layout requires no framing modification — the niche box drops into the existing stud bay. A custom-size niche (wider than 14-and-a-half inches, or set across a stud line for a centered layout) requires cross-blocking the wall studs, adding sister studs at the new opening edges, and a header above and a sill below the niche opening. We measure the wall layout on the booking visit and tell you on the spot whether the niche you want is a standard drop-in or a framing-mod build.
Framing — KERDI-Board Box or Pre-Fab Insert
Two niche-build paths. The KERDI-Board box path frames the niche directly with KERDI-Board panel cuts — back panel, two sides, top, and bottom (or one or two shelf dividers on a double-shelf layout) — fastened with KERDI-Fix sealant and panel washers, seamed with KERDI-Band at every inside corner. This path gives the most flexibility on layout, depth, and finish — and is the standard Handis build on every niche. A pre-fab insert (Schluter KERDI-BOARD-SN, Wedi Niche, or a third-party stainless-tray insert) is an option on a quick budget build, set into the framed opening and seamed to the surrounding membrane with KERDI-Band. We recommend on the booking call based on the layout and finish you want.
Bench — Floating Wall-Mounted or Built-In Corner
Two bench-build paths. The floating wall-mounted bench is a KERDI-Board panel cantilevered from blocking inside the wall, finished with tile on the top, the front face, and the bottom (which is visible from the shower-pan side). The built-in corner bench is a triangular or rectangular framed seat in a shower corner, framed with cement-board substrate and KERDI-Board over the top, with a mortar-bed top sloped one-quarter inch per foot toward the open shower side to shed standing water. Both paths seam into the surrounding wall and pan membrane with KERDI-Band. Bench load capacity on the floating wall-mounted style is rated for a 350-pound static load when properly blocked; the built-in corner bench has no load limit because it transfers load to the pan and the wall framing directly.
Membrane Tie-In — KERDI-Band at Every Seam
Every inside corner of the niche box, every joint between the niche and the surrounding wall, every bench-to-wall transition, every bench-to-pan transition gets KERDI-Band seam tape bedded in thinset and rolled flat. The niche tie-in to the surrounding wall membrane is the failure point that distinguishes a real waterproof niche from a leak waiting to happen. We do not skip seam tape on a niche or a bench. No exceptions.
Tile Finish — Coordinated with the Wall Pattern
Niche back tile usually carries an accent material that contrasts with the surrounding wall — small-format glass mosaic, large-format porcelain in a contrasting color, marble or other natural stone for a feature back, or the same field tile turned 90 degrees for a subtle accent. Niche shelf is tempered glass on stainless clips for the cleanest look, or a tiled-over edge for a continuous tile read. Bench top is the same field tile as the wall in most layouts, or a contrasting top for a feature seat. We sample the layout on the wall before tile install starts so the finished look matches the homeowner's expectation.
Niche Lighting — Licensed Electrician Subcontract
LED strip lighting set into the top edge of a niche (the under-shelf accent that makes a niche read at night) requires a hardwired 12V or 24V transformer, a low-voltage feed cable, and the strip fixture itself rated for wet-area exposure. The hardwired electrical work — running the new circuit or branch wiring, mounting the transformer, and connecting at the panel — routes to a licensed Washington L&I electrician as a coordinated subcontract on a separate invoice. Handis frames the chase for the strip, sets the strip fixture, and tiles around it. The electrician handles the wired connection.
How a Shower Niche & Bench Build Works
Seven sequential steps from layout to tile finish — measure, frame, KERDI-Board cut, seam tape, membrane tie-in, tile, and final caulk. The actual sequence we follow on every niche and bench.
Measure, Lay Out, and Confirm Stud-Bay vs Custom Size
Niche or bench location chalk-lined on the wall. Stud locations confirmed with a magnetic finder and a probe hole at the niche corners. We tell you on the spot whether the niche you want is a standard drop-in (between two studs, no framing mod) or a framing-mod build (cross-blocked, sister-studded, header and sill added). Bench layout sketched and confirmed for height and depth.
Framing Modifications Where Required
For a custom-size niche or a built-in bench, the wall framing is modified — cross-blocking added where the niche crosses a stud line, sister studs added at the new opening edges, header and sill added at the top and bottom of the niche opening, blocking added inside the wall for a wall-mounted bench cantilever. Standard stud-bay niches skip this step and drop directly into the existing bay.
KERDI-Board Box or Bench Frame Cut and Set
KERDI-Board panels cut to the niche box dimensions or the bench frame dimensions, set into the framed opening with KERDI-Fix sealant and panel washers. Shelf dividers added on a double-shelf niche. Bench cement-board substrate set first on the built-in corner style, with KERDI-Board overlay on top.
KERDI-Band Seam Tape at Every Inside Corner
KERDI-Band bedded in thinset and rolled flat at every inside corner of the niche box, every joint between the niche and the surrounding wall, every bench-to-wall transition, and every bench-to-pan transition. The niche-to-wall tie-in is the failure point that separates a real waterproof niche from a leak path. We do not skip a seam.
Membrane Tie-In to the Surrounding Wall and Pan
Niche or bench membrane tied into the surrounding KERDI sheet (or KERDI-Board panel) wall membrane and the pan membrane below. KERDI-Band runs continuous from the niche-corner seam onto the surrounding wall membrane. Every change-of-plane is covered. Visual walk-through with the homeowner before tile install.
Tile the Niche, the Bench, and the Surrounding Wall in Sequence
Field tile on the wall around the niche set first to establish the layout. Niche back tile (accent material, mosaic, or feature stone) set next. Niche shelf installed (tempered glass on stainless clips or a tiled-over edge). Bench top tile set on the sloped mortar bed, bench face and visible-bottom tile follow. Grout, sanded or unsanded by joint width, applied and sealed.
Final Caulk in 100% Silicone at Every Change-of-Plane
Inside corners of the niche, niche-to-wall front edge, bench-to-wall corner, bench-to-pan corner — every change-of-plane where the tile movement could open a grout joint is caulked in 100 percent mildew-resistant silicone instead of grout. Silicone moves with the wall; grout cracks. Final caulk skins in 30 to 60 minutes and reaches full cure in 48 hours.
Shower Niche & Bench Pricing
Final pricing depends on whether the niche is a standard stud-bay drop-in or a custom-size framing-mod build, the bench style (floating wall-mounted, built-in corner, or full bench combo), the accent material on the niche back, and whether a niche-light is in scope. Hardwired niche-light wiring routes to a licensed Washington L&I electrician; their portion passes through transparently with the line item named. Tile material cost is separate from the install labor priced here. Request a free estimate for an accurate quote.

Why Handis for Shower Niche & Bench Builds
A niche is the cheapest visible upgrade a shower can get and the easiest to get wrong. The big-box pre-fab niche kit at $79 with the visible bullnose seam at every edge, the field-cut KERDI patch around a non-bonded niche tray, the eight-by-twelve niche box set across a stud line with no cross-blocking and a wall above it that flexes under the niche edge every time someone closes the bathroom door — these are the niches we get called to rebuild three years after they were installed. A purpose-framed KERDI-Board niche tied into the wall membrane with KERDI-Band at every seam is what a niche should look like, and it costs $700 to do right the first time versus $1,500 to rip out and rebuild after the wrong one fails. The bench math is similar — a real built-in is framed to carry the load and sloped to shed water, not a slab of plywood with a tile veneer.
KERDI-Board box, not a pre-fab insert
Every Handis niche is framed and built from KERDI-Board panel cuts, sealed with KERDI-Fix and washers, seamed with KERDI-Band at every inside corner, and tied into the surrounding wall membrane. We will install a pre-fab Schluter KERDI-BOARD-SN insert or a Wedi Niche on request when the budget is tight and the layout matches, but the default Handis build is a custom KERDI-Board box that fits the homeowner's layout exactly.
Stud-bay vs custom-size — honest on the booking call
A standard niche between two studs needs no framing modification and drops in at the lower price tier. A custom-size or centered-on-wall niche needs cross-blocking, sister studs, a header, and a sill — that is the framing-mod price tier. We measure the wall on the booking visit and tell you on the spot which tier the niche you want falls into, before you commit.
Bench framed to carry the load and sloped to shed water
A floating wall-mounted bench is rated for a 350-pound static load when blocked properly inside the wall — that is a Handis spec, not a wishful number. A built-in corner bench has its load transferred to the pan and the wall framing directly, no rated limit. Every bench top is sloped one-quarter inch per foot toward the open shower side so standing water rolls off; a flat bench top is a mildew incubator.
KERDI-Band on every seam — no shortcut on the niche tie-in
The seam between the niche box and the surrounding wall membrane is the single most common failure point on a niche install. We seam every corner with KERDI-Band bedded in thinset and rolled flat — no exceptions, no shortcuts on a niche tie-in because the corner is hidden.
Hardwired niche-light routes to a licensed electrician
LED strip lighting set into the top edge of a niche needs a hardwired transformer, a low-voltage feed cable, and a wet-rated strip fixture. The hardwired electrical work (new circuit or branch wiring, transformer mount, panel connection) routes to a licensed Washington L&I electrician on a separate invoice. Handis frames the strip chase, sets the wet-rated strip fixture, and tiles around. The electrician handles the connection. We name the electrician on the quote line by line.
One-year project warranty on the niche and bench scope
Handis carries general liability and workers' compensation; every technician has cleared a background screening before the first job. The one-year project warranty covers the KERDI-Board frame, the seam tape, the membrane tie-in, the bench load rating, and the tile install — if a niche seam opens, a bench shows movement, or a tile cracks inside a year because of our workmanship or prep, we come back and rebuild the affected section at no charge.
Estimate
Tell us the shower (master, guest, hall, walk-in), where on the wall you want the niche (single, double, height preference), whether you want a bench in scope (floating wall-mounted, built-in corner, or both), the accent material you have in mind for the niche back (glass mosaic, marble, contrasting porcelain), and whether a niche-light is in scope (LED strip with electrician sub). Send phone photos of the existing shower if it is already framed. We quote framing, KERDI-Board scope, seam tape, tile install, and any electrician-sub portion before booking.
Customer Reviews
Shower niche and bench reviews from real Handis customers.
Single recessed niche in the master shower wall, KERDI-Board box, tempered glass shelf at mid-height, contrasting marble mosaic at the back. The tech measured the stud bay on arrival, confirmed it was a standard drop-in (no framing mod needed), built and tiled the niche in two days as part of the larger shower rebuild. The mosaic back looks like a feature, not a storage hack.
Custom 24-inch-wide niche centered on the long shower wall. Required cross-blocking and sister studs because it crossed a stud line. Handis was upfront on the booking call that this was the framing-mod tier, walked us through the cost difference vs the stud-bay drop-in. The finished niche reads as a designed feature, not a tacked-on box. Worth the extra cost.
Floating wall-mounted bench in the master walk-in. KERDI-Board top, front, and bottom, cantilevered from blocking inside the wall, tiled in the same field porcelain as the wall. Tech showed me the load test (he sat on it and bounced) before the tile went on. The bench is rock-solid and reads as a built-in piece of the architecture.
Built-in corner bench in the guest shower with a sloped mortar-bed top. The slope is subtle enough that you do not feel it sitting on the bench, but standing water rolls right off after a shower. No mildew at the bench-to-wall corner, six months in. The KERDI-Band seam at the corner is invisible under the tile but I watched them install it.
Full corner-bench-and-niche combo in our master with a coordinated tile pattern across both. Handis ran the niche-light electrical through their vetted Washington L&I electrician for the LED strip transformer; the strip fixture set into the top of the niche reads beautifully at night. Two contractors, one coordinated project, named portions on the quote.
