Cambridge Pavers Bathroom Remodeling: The Pomona Owner’s Guide
Cambridge Pavers bathroom remodeling in Pomona typically runs $9,000-$28,000 for a full replacement, and we stock compatible materials for same-week installation across the full Cambridge line. Most Pomona owners first notice trouble when grout lines crack between the paver tiles, water pools on the surface, or the mortar bed underneath starts sounding hollow when tapped. These symptoms usually show up after 8-15 years in our climate, where thermal cycling between hot inland afternoons and cooler nights stresses the installation.
Grant Rowan likes to say, “Measure twice, then we can talk.” That habit started early - he grew up in Los Angeles watching relatives patch and pour through weekend projects, then trained at Los Angeles Trade-Technical College before the first callus hardened. His crew has worked steadily across Pomona, from residential jobs near the Fairplex corridor to commercial work closer to downtown.
Which Cambridge Pavers Models This Applies To
Cambridge Pavers produces several product lines used in bathroom applications, and matching the right material matters for warranty coverage and performance. The most common we encounter in Pomona are the ArmorTec and Sherwood series, both of which carry a textured surface finish that hides wear but also traps moisture if the sealant fails. Check the underside of a loose paver for the stamped model code, or measure the nominal thickness - ArmorTec runs 2⅜ inches, while Sherwood and the older Cobble series run 2¼ inches. That eighth-inch difference affects mortar bed depth and drainage slope calculations.
We are an independent service provider, not affiliated with Cambridge Pavers. For most Pomona bathroom jobs, we source direct from Cambridge’s Ontario distribution yard when lead times allow, or pull from our vetted equivalent stock - Belgard and Techo-Bloc pavers that match the spec sheet - when speed matters. The OEM versus aftermarket decision usually comes down to whether your existing installation is still under Cambridge’s limited lifetime warranty; mixing series voids that coverage, which we flag in writing before ordering.
Signs Your Cambridge Pavers Bathroom Remodeling Is Failing

- Grout cracking along control joints. Cambridge’s rigid substrate recommendations don’t always account for Pomona’s expansive clay soils, which shift seasonally. When the subfloor moves and the grout doesn’t, the grout loses.
- Water pooling instead of draining. The ¼-inch-per-foot slope specified in Cambridge’s installation guide degrades when the mortar bed settles or the weep screed (the drainage gap at the wall base) clogs with calcium buildup from hard Pomona water.
- Hollow sound when you tap the surface. This means the thinset or mortar bed has delaminated from the substrate, usually from moisture infiltration through failed sealant. The paver itself is fine; what’s underneath isn’t holding it.
- Efflorescence - white powder on the surface. Moisture is migrating through the paver body and depositing mineral salts. In Pomona’s low-humidity climate, this signals an active leak below, not normal evaporation.
- Loose pavers that rock underfoot. The bedding layer has eroded or the paver has fractured at a stress point. Cambridge’s ArmorTec holds up better here, but the older Cobble series shows this after a decade of thermal cycling.

AfterReplacement Cost & What’s Included
A full Cambridge Pavers bathroom remodel in Pomona runs $9,000-$28,000, with most projects we quote falling between $12,000 and $18,000. The range depends on three things: whether we’re working over an existing slab or cutting to the joists, how many fixture relocations are involved, and whether the original installation used a traditional mortar bed or a newer membrane system.
| Component | Price Range |
|---|---|
| Demolition and haul-away | $1,200-$3,500 |
| Substrate repair or replacement | $2,000-$6,000 |
| Cambridge Pavers material (OEM or equivalent) | $3,500-$9,000 |
| Mortar bed and waterproof membrane | $1,800-$5,500 |
| Grout, sealant, and finishing | $800-$2,500 |
| Fixtures and trim (if replacing) | $1,500-$7,000 |
Under Clause 1 of the Haven Standard, you get a written price before anyone picks up a hammer. The quote is flat, with line-item breakdown, and no change proceeds without a signed change order. Our 365-Day Done Right Promise covers the workmanship; material warranties run through the manufacturer. Every visit includes a documented photo record, included, not optional.
DIY or Call Us?

There’s a safe middle ground here. An owner can check for loose pavers, photograph the model stamp, and verify drainage slope with a level - that’s useful information that speeds our quote. What doesn’t work safely is breaking into a mortar bed over a wood subfloor without knowing where the plumbing runs, or disturbing a waterproof membrane that ties into wall systems. We’ve found pipes where no diagram said they’d be, especially in Pomona’s older stock near Lincoln Park where renovations stack atop previous renovations.
The real risk isn’t the pavers; it’s what you can’t see. A compromised membrane in a second-floor bathroom means water hitting ceiling drywall below, and that damage multiplies fast. If you’re seeing the symptoms above, call (626) 606-1081 and we’ll schedule a free estimate. We’ll show you the photo record, name the price in writing, and you decide from there.
FAQs
Expect 15-25 years for the paver itself, but the installation system usually fails first. In Pomona’s climate, the thermal cycle and hard water stress the mortar bed and sealant before the paver wears. Call (626) 606-1081 for an exact quote - estimates are free.
Individual paver replacement is possible if you have matching stock, but we rarely recommend it. The underlying failure - membrane, mortar bed, or slope - affects the whole field, and spot fixes create elevation differences that trip the next failure. Call (626) 606-1081 for an exact quote - estimates are free.
Most Pomona jobs run 10-18 working days from demolition to final seal, assuming no substrate surprises. We build in a 48-hour cure for each mortar and membrane layer; rushing that is how callbacks happen. Call (626) 606-1081 for an exact quote - estimates are free.
We don’t carry full paver inventory mobile - the weight and variety make that impractical - but we maintain active accounts with Cambridge’s Ontario yard and keep Belgard and Techo-Bloc equivalents in rotation for urgent jobs. Most materials are on-site within 48 hours of quote acceptance. Call (626) 606-1081 for an exact quote - estimates are free.
