A Schluter Kerdi shower kit typically costs $450-$1,100 for the kit alone, with a common midrange price around $700-$800 before tile and installation. The final budget depends mainly on shower dimensions, drain style, included waterproofing parts, local labor rates, and whether the project is a new installation or a full shower replacement.

| Kerdi shower kit | $450 | $750 | $1,100 | Kit size and included components vary |
| Additional waterproofing supplies | $50 | $150 | $350 | More may be needed for niches or benches |
| Installation labor | $1,200 | $2,500 | $4,500 | Waterproofing and pan work, excluding some tile scope |
| Installed shower project | $3,500 | $7,500 | $14,000+ | Tile, demolition, plumbing, and finish choices drive totals |
What a Kerdi shower kit costs by size and scope
For the kit itself, most homeowners should budget about $450-$1,100, with roughly $750 typical for a standard shower package. Smaller or simpler packages may include a foam shower tray, curb, drain, waterproofing membrane, and sealing accessories. Larger packages or versions with additional components can cost more. Retailer prices, availability, drain configuration, and package contents change the quote, so the included-parts list matters as much as the label price.
A compact shower kit for a footprint around 32 by 60 inches often falls near $450-$700. A more complete or larger package for a shower near 38 by 60 inches can land around $650-$1,100. These ranges refer to the system components, not tile, thin-set mortar, plumbing changes, or installation labor. Some kits are built around a specific drain location or tray shape, which can affect whether extra parts are required.
For a professionally installed, tiled shower, a broad budget is $3,500-$14,000 or more. A straightforward replacement with accessible plumbing, economical tile, and limited demolition may be near the low end. A custom shower with premium tile, a bench, niche, new valve, or extensive substrate repairs can exceed the high end. Assumptions: U.S. pricing, standard residential bathroom, ordinary access, and no major structural or mold remediation.
How tray, drain, membrane, and labor shape the quote
The kit is only one part of the bill; labor, tile, and site preparation often cost more than the waterproofing package. The table below separates common components for a standard-size tiled shower. Actual quotes may group tasks together, and some installers include consumables in their labor charge.
| Quote component | Typical range | Unit basis | What changes the price | Usually included |
|---|---|---|---|---|
| Kerdi kit | $450-$1,100 | Per package | Tray dimensions, drain and package contents | Tray, membrane, drain parts, curb on many kits |
| Extra membrane and seals | $50-$350 | Per shower | Niche, bench, corners, and wall coverage | Only when kit quantity is insufficient |
| Tile and setting materials | $500-$2,500 | Per project | Tile grade, layout, mortar, grout, and waste | Often priced separately |
| Waterproofing and pan labor | $600-$1,800 | Per shower | Substrate condition and drain alignment | Tray, membrane, seams, and flood test |
| Tile installation labor | $1,200-$4,500 | Per project | Tile size, pattern, niche work, and finish detail | May exclude demolition and plumbing |
| Demolition and disposal | $300-$1,500 | Per project | Existing tile, access, and debris volume | Frequently quoted as a separate task |
Contractors may also charge for cement board or other approved substrate preparation, plumbing adjustments, a new mixing valve, and local permit fees. Get the quote to distinguish kit materials from installation supplies and confirm whether the contractor is responsible for checking seams and drain connections before tile covers them.
For example, 20-35 hours of combined preparation and waterproofing work at $60-$100 per hour represents about $1,200-$3,500 in labor, before tile-setting time. Some contractors quote by the project rather than showing this calculation.
Which shower dimensions and drain details raise the price?
Shower footprint, tray fit, drain position, and added wall features are the most direct system-specific cost drivers. A tray that matches the framed opening can reduce cutting and floor preparation. If the base must be trimmed, the subfloor needs leveling, or the drain needs relocation, labor and materials can increase even when the kit price stays the same.
A 32-by-60-inch shower generally uses less tray and wall coverage than a larger footprint, while a 38-by-60-inch or custom-size space can require a higher-priced package or additional membrane. Verify the finished inside dimensions and the tray’s permitted cutting limits before ordering. A mismatch can create extra work or require a different base rather than a simple field adjustment.
Drain style and location matter, too. A standard center drain may fit an existing rough-in, but moving plumbing can add roughly $300-$1,200, depending on floor access and pipe routing. Linear-drain configurations can add several hundred dollars or more to materials and may require precise floor slope planning. Confirm drain compatibility with the selected tray and the installer’s preferred system components.
Each niche, bench, curb change, or complicated corner creates more seams and detailing. A single recessed niche may add about $150-$500 for materials and labor, while a built-in bench can add $400-$1,500 or more depending on size and construction. Extra membrane, seals, and labor should be listed rather than assumed to be included in the base kit. Assumptions: Typical residential labor; difficult access and extensive repairs can increase these ranges.
How installation hours and crew rates affect the total
Waterproofing installation is a precision task, and the schedule often includes curing or inspection time between work stages. For an uncomplicated shower, preparation and tray installation may take one workday, with membrane installation and detailing taking another half to one day. Tile installation is a separate phase that can take several additional days depending on the pattern, tile size, and grout schedule.
Residential tile and remodeling labor commonly runs about $50-$100 per hour per worker in many markets, though local rates can fall outside that range. A small crew may spend 15-30 labor hours on demolition, substrate preparation, tray fitting, and waterproofing for a straightforward job. Tile setting, plumbing changes, and finish work add hours beyond that.
Ask whether the estimate is based on a fixed project price or hourly billing, and identify what happens if damaged framing, an uneven floor, or plumbing issues appear after demolition. A written scope should state who supplies the kit, who verifies the tray slope and drain connection, whether a flood test is included, and which return visits are covered. A low labor quote that omits substrate preparation or waterproofing checks may not represent the same scope as a higher bid.
Scheduling can also affect labor charges. A contractor working around occupied bathrooms, limited access, or a tight completion deadline may charge more for repeated trips or rushed work. Allowing time for proper sequencing is generally less costly than paying for expedited scheduling or correcting concealed leaks later.
Three realistic Kerdi shower quotes for different projects
Comparing itemized examples helps show why the kit’s shelf price does not predict the project total. These illustrative budgets assume ordinary access and U.S. labor; local bids, tile selection, and concealed conditions can change each figure.
| Project scenario | Kit and supplies | Labor scope | Estimated total |
|---|---|---|---|
| 32-by-60-inch replacement, basic tile, drain unchanged | $600-$850 | 30-40 hours at $60-$85 per hour | $4,000-$6,500 |
| 38-by-60-inch shower, one niche, midrange tile | $800-$1,250 | 45-60 hours at $65-$95 per hour | $6,500-$10,500 |
| Custom shower with bench, linear drain, premium tile | $1,200-$2,000 | 65-90 hours at $75-$110 per hour | $10,000-$17,000+ |
The first example assumes limited demolition, no valve replacement, and no major subfloor repair. The second includes more detailing and tile labor, but assumes the drain can remain close to its existing location. The custom example accounts for more complex waterproofing and finish work; it may also require plumbing, framing, or permit expenses not included in every contractor’s quote.
Before comparing bids, check that each covers the same shower dimensions, tile area, demolition, disposal, plumbing, waterproofing, and finish details. A quote that excludes the shower door, fixture trim, or niche can appear substantially cheaper while leaving those items for later spending.
How regional labor and delivery shift U.S. prices
Labor markets usually create a bigger regional difference than the price of the same boxed kit. In high-cost metropolitan areas, installed shower quotes can run roughly 15%-35% above a national middle-market estimate because of higher trade rates, parking or access limits, and contractor demand. Smaller cities and rural areas may come in 5%-20% below a typical metro quote, although fewer available installers can offset the lower hourly rate.
For example, a straightforward $6,000 project in a moderate-cost market might price around $6,900-$8,100 in a high-cost city with a similar scope. In a lower-cost area, it could be closer to $4,800-$5,700. These are planning adjustments, not fixed regional price lists; local tile prices, disposal fees, and code requirements matter as well.
Shipping a heavy or bulky shower tray can add about $50-$200 when it is not included in the retailer’s price. Remote delivery, stairs, restricted parking, or carrying materials through a finished home may add handling charges. Ask whether the quote includes delivery and whether a missed delivery or damaged component would delay the crew at additional cost.
Get at least three local bids where possible, and compare labor scope rather than using percentage adjustments alone. A contractor familiar with the specific system may price the job differently from a general remodeler, but the estimate should still identify waterproofing materials, installation steps, and warranty terms.
Which add-ons and site repairs are easy to miss?
Demolition, plumbing, tile accessories, and disposal can add hundreds or thousands beyond the kit price. Removing an existing shower commonly costs $300-$1,500, with higher charges for heavy tile, multiple layers, difficult access, or extensive debris. A dumpster or haul-away fee may be separate, so the estimate should state how waste is removed.
Replacing a shower valve may add about $250-$800 for parts and labor when access is straightforward. Relocating a valve, drain, or water supply can cost more, particularly if the installer must open finished walls or reinforce framing. Subfloor repair may add $200-$1,000 for localized damage; wider water damage or mold remediation can push the expense substantially higher.
Tile edging, grout, sealant where applicable, niche shelves, and shower fixtures are often outside the kit package. These may add $150-$800 for common accessory choices, excluding premium fixtures or a glass enclosure. A custom glass door can add approximately $700-$2,000 or more, depending on size, hardware, and installation requirements.
Some jurisdictions require permits for plumbing alterations or substantial bathroom remodeling. Fees often range from $50-$500, but local rules and inspection requirements differ. Ask the contractor to identify permit responsibility and any likely code upgrades before work starts; required changes to ventilation, electrical protection, or plumbing can add costs not visible in a kit-only estimate.
Where homeowners can trim the Kerdi shower budget
The safest savings usually come from controlling scope and avoiding unnecessary plumbing or finish upgrades, not from skipping waterproofing details. Keep the existing drain location when the layout permits, choose a tray that fits the measured opening, and limit custom features that add corners and seams. Each avoided relocation or elaborate built-in can reduce both material and labor charges.
Compare the kit’s exact contents before choosing a lower-priced package. A package that lacks the required curb, drain parts, or membrane may cost less at checkout but require separate purchases. Price the complete bill of materials, including thin-set mortar, seals, additional membrane, and any system-specific accessories, before deciding that one retailer has the better deal.
Tile selection can meaningfully affect the installation budget. Straightforward ceramic or porcelain tile may cost about $2-$8 per square foot for materials, while specialty stone and mosaic products can run $10-$30 or more per square foot. Small mosaics, complex patterns, and many cuts may increase labor even when the material itself is inexpensive. Ask for separate material and installation rates before selecting a pattern.
Prepare the room by clearing personal items and confirming access, but do not remove finishes or alter framing unless the contractor agrees; unplanned work can void assumptions in the quote. Request written bids with the same dimensions and scope, and ask whether the price includes flood testing, disposal, permits, and a workmanship warranty. Assumptions: Savings depend on local labor and the existing shower condition.
