Schluter Bathroom Remodeling: The San Francisco Owner’s Guide
A full Schluter-system bathroom remodel in San Francisco typically runs $10,620 to $33,040 installed, and most projects take two to four weeks once demolition starts. We stock Schluter KERDI membranes, DITRA uncoupling mats, KERDI-BOARD panels, and the matching profiles, corners, and drain assemblies on the truck, so a failed waterproofing layer or a cracked shower pan doesn’t have to mean weeks of waiting. The usual story we hear: a homeowner pulls up a loose tile near the shower curb and finds the substrate underneath has been soaking up water for months. Fog-driven moisture in neighborhoods like the Outer Sunset makes that failure move faster than it would in, say, the Mission, because the walls never truly dry out.
Key Takeaways:
- Schluter bathroom remodels in San Francisco: $10,620 – $33,040 installed
- We stock KERDI, DITRA, KERDI-BOARD, and the matching profiles and drains
- Most failures trace back to improper substrate prep or a failed corner seal, not the membrane itself
- Every job gets a written price before work starts and a 365-day written guarantee after it’s done
Which Schluter Models This Applies To
Schluter’s bathroom line splits into three main families: the KERDI waterproofing membranes (sheet-applied over drywall or cement board), the KERDI-BOARD foam panels (structural waterproof backer in one piece), and the DITRA uncoupling membranes (for floor tile over wood or concrete subfloors). Within those families you’ll find the KERDI-SHOWER kits, which include the pre-sloped tray, curb, and drain assembly in 48×48, 60×32, and 72×72 configurations. If you have a spec sheet or a leftover box, look for the model number printed along the edge: KERDI-SHOWER-TS for a centered drain, KERDI-SHOWER-LTS for a linear drain against one wall. The drain grate cover will also carry a part number starting with KD or KL. If you don’t have paperwork, the outside measurement between tiling flanges will tell us which kit you’re on.
One compatibility gotcha that trips up San Francisco DIYers: the KERDI-SHOWER tray requires a dead-flat subfloor, and most 1920s-era bathrooms in the Richmond and Sunset sit on a floor that has settled a quarter-inch or more. You can’t shim a foam tray to fix that. The substrate has to be leveled first, or the tray flexes and the grout lines crack within the first year. We use Schluter’s own system components rather than aftermarket equivalents because the corner seals and pipe collars are engineered to bond to KERDI’s fleece-webbing surface. A generic off-brand corner may look identical, but if the fleece backing is thinner, the thin-set won’t grab it the same way.

Signs Your Schluter Bathroom Remodeling Is Failing
- Loose or hollow-sounding floor tiles near the shower. This is usually a de-bonded DITRA membrane underneath. The uncoupling mat may have been installed over a subfloor that was too flexible, or the thin-set was allowed to skin over before the mat went down.
- Efflorescence or dark staining at the base of the shower curb. Water is wicking through a compromised corner seal where the curb meets the wall membrane. In San Francisco’s coastal zones, this shows up faster because the surrounding air is already moisture-heavy and evaporation is slow.
- Musty smell that won’t clear, even after cleaning. Water has reached the framing behind the KERDI and the wood is holding it. The membrane itself doesn’t rot, but the studs behind it do.
- Cracked grout lines running in a straight row across the floor. That pattern points to subfloor movement, not grout failure. The DITRA mat is doing its job absorbing movement, but if the subfloor deflection is beyond spec, even DITRA can’t hold the tile assembly together indefinitely.
- Water pooling at the drain instead of running toward it. The pre-sloped tray has settled or the drain assembly has shifted. A properly installed KERDI-SHOWER tray drains dry within minutes; standing water means the pitch is gone.
Replacement Cost & What’s Included
A Schluter bathroom remodel in San Francisco runs $10,620 to $33,040 depending on scope. That range is driven by three things: square footage of tile surface, whether we’re replacing the shower pan only or gutting to the studs, and what’s hiding behind the walls once we open them up. Here’s the line-item breakdown so you can see where the money goes:
| Scope of Work | Typical San Francisco Range |
|---|---|
| Schluter shower pan replacement (KERDI tray + drain + curb) | $4,130 – $8,850 |
| Tub-to-shower conversion with full KERDI waterproofing | $4,130 – $11,800 |
| Complete bathroom remodel with Schluter system (gut to studs) | $10,620 – $33,040 |
| Floor tile replacement over DITRA membrane | $2,360 – $5,310 |
Every one of those ranges includes parts, labor, demolition, haul-off, and the written guarantee. We don’t hand you an estimate with an asterisk and then “discover” problems later. If we open the wall and find rotted framing, we document it, we show you, and we give you a written change order before we touch the next stick of lumber. That’s the Garrison Standard, and it’s non-negotiable.

A Schluter system is only as good as the substrate under it and the thin-set bond holding it. The parts themselves aren’t dangerous to handle the way a garage door spring or an electrical panel is, but the failure mode here is quiet: a small gap in a corner seal lets water track behind the membrane for years before you see a single crack in the tile. If your issue is cosmetic, like a loose towel bar or a cracked corner shelf, that’s a Saturday job for a homeowner who’s handy. If the symptom involves water staining, loose tile, or a shower that’s leaking to the floor below, we recommend you stop at the inspection stage and call (831) 610-5598. We’ll tell you over the phone whether it sounds like a seal failure, a tray settlement issue, or something unrelated to the Schluter system, and we’ll give you a straight number for the fix.
Straight number, real scope, no surprises at close-out. That’s how Curtis Lane runs every job, and it’s why we put the price in writing before the first tile comes off the wall.
FAQs
A properly installed Schluter system should hold for 20 to 30 years, but San Francisco’s fog belt shortens the margin for error. In the Outer Sunset and Richmond, we inspect Schluter installs that are failing at the eight-year mark almost exclusively because of substrate movement or an improperly sealed corner, not because the membrane wore out. Call (831) 610-5598 and we’ll inspect yours and tell you what’s actually failing.
If the failure is a corner seal or a loose drain assembly, we can often repair that section without gutting the shower. If the subfloor underneath has moved or the framing is water-damaged, the repair scope grows. We won’t know until we open the tile, and we’ll give you a written price before that happens. Call (831) 610-5598 for an inspection.
A shower pan replacement runs three to five working days. A full gut-and-rebuild bathroom runs two to four weeks, depending on what we find inside the walls and whether we’re moving plumbing. We’ll give you a written timeline in the estimate, and we hold to it. Call (831) 610-5598 to schedule a site walk.
We keep KERDI-BOARD panels, DITRA mat rolls, KERDI membrane, corner seals, pipe collars, drain assemblies, and the common profile trims on the truck as stock items. Odd-size shower trays and special-order drain grates come from our supplier within three to five business days. We’re an independent contractor, not affiliated with Schluter, which means we stock and install their system because it works, not because a distributor tells us to. Call (831) 610-5598 and ask for Curtis. He’ll tell you straight whether we have the part on hand.

If you’re standing in a bathroom with a cracked shower floor or a wall that’s been seeping behind the tile, call us. We’ll schedule a site walk, we’ll open the wall if it’s safe to do so, and we’ll hand you a written price with a real scope attached. No numbers that move at the door, no surprise change orders. We also work with KraftMaid, Cambria, and Silestone for the finishes around your Schluter system, so the whole bathroom can be specified, priced, and installed by one crew.
