Schluter Bathroom Remodeling Nationwide

Schluter Bathroom Remodeling: The Sunnyvale Owner’s Guide

Schluter bathroom remodeling in Sunnyvale typically runs $9,000-$28,000 for a full replacement, with Schluter-DITRA and Schluter-KERDI membrane systems installed to manufacturer spec. We stock Schluter-compatible profiles, drains, and waterproofing components for same-day starts on most jobs. Most Sunnyvale owners first notice trouble when grout cracks along shower curbs or tile loosens over a plywood subfloor that needed DITRA-HEAT decoupling from the start.

Which Schluter Systems This Applies To

We work with the full Schluter residential line: KERDI waterproofing membranes for shower walls and floors, DITRA and DITRA-HEAT uncoupling membranes for tile-over-plywood or concrete slabs, and Schluter-SHOWER prefabricated trays and curbs. Each system has a specific bonding flange thickness - KERDI is 4 mil, KERDI-DS for steam rooms is 8 mil - and mixing these up during repair work means the KERDI-FIX sealant won’t seat properly at seams.

To identify your existing system, look for the orange KERDI membrane at drain cutouts or the orange grid-pattern DITRA under removed tile. The Schluter drain assembly model (KERDI-DRAIN with 2-inch or 3-inch outlet, KERDI-LINE linear) is stamped on the stainless flange underside. We’re an independent service provider, not affiliated with Schluter Systems, and we source OEM Schluter components plus compatible alternatives from Laticrete Hydro Ban and NobleSeal when the job calls for it. The compatibility gotcha in Sunnyvale’s 1950s-1970s ranch stock: original showers often have 2-inch drains where modern KERDI-DRAIN specs prefer 3-inch, so we verify rough-in diameter before ordering parts.

Signs Your Schluter Bathroom Is Failing

• Grout cracking at shower curbs and corners. The KERDI membrane behind the tile may have a seam gap or the curb wasn’t wrapped with KERDI-KERECK preformed corners. Water wicks through, swells the curb framing, and the grout line opens within 18-24 months in Sunnyvale’s dry-season contraction cycles.
• Tile sounding hollow when tapped. DITRA wasn’t fully embedded in thinset, or the plywood subfloor flexes beyond L/360 deflection. The uncoupling function fails, and tiles “pop” loose without the membrane absorbing the movement.
• Musty odor from walls adjacent to the shower. The KERDI membrane terminated below the showerhead height, or KERDI-BAND seam tape was skimped at niche joints. Moisture hits drywall through a single gap.
• Heated floor zones not warming evenly. DITRA-HEAT cable was spaced inconsistently during install, or a cable loop was damaged by a fastener through the membrane. We find this in Lakewood Village remodels where original owners self-installed.
• Drain staining or slow drainage with no hair clog. The KERDI-DRAIN bonding flange separated from the membrane, or the clamping ring was overtightened and cracked the PVC adapter. Water tracks along the drain body instead of entering it.

Replacement Cost & What’s Included

The range depends on three factors: whether we remove existing tile and substrate or overlay where possible, whether the drain rough-in needs relocation (common in older Sunnyvale slabs), and whether DITRA-HEAT requires a dedicated GFCI circuit. Under Clause 1 of The Haven Standard, you get a written line-item price before anyone picks up a tool - material costs, labor hours, and subcontractor scope listed separately. Our 365-Day Done Right Promise covers workmanship; Schluter’s system warranty covers materials when installed to their spec, which we document with photos at every membrane seam and flood-test stage.

DIY or Call Us?

There’s honest work a homeowner can do: verify your drain diameter with a tape measure, photograph existing membrane labels before demolition, and check that your subfloor is 3/4-inch tongue-and-groove plywood (anything less needs reinforcement before DITRA).

Where DIY goes wrong is the membrane lapping and sealing. KERDI-BAND overlaps must be 2 inches minimum, KERDI-FIX needs a 3/16-inch bead at changes of plane, and flood-testing requires a 24-hour water dam at the curb - miss any of these and the warranty is void, the leak is hidden, and the repair tears out twice the work. In Sunnyvale’s tight crawl spaces and slab-on-grade construction, drain relocation also means concrete cutting that most owners don’t have the tooling for. Call (650) 405-3637 and we’ll scope it in person, with a written estimate you can compare against any other bid.
