Tremron Bathroom Remodeling: The Orange County Owner’s Guide
A Tremron bathroom remodel in Orange County typically runs $9,000 to $28,000 installed, depending on whether we’re updating a powder room or reworking a master bath with a new shower pan and full tile. Most homeowners reach out after a shower pan shifts, a curb cracks, or water starts staining the ceiling below. We stock Tremron-compatible materials and install them with a written price before any work starts.
The usual discovery moment is a damp smell near the shower or grout that won’t stay sealed. By the time you’re reading this, you’ve probably already looked behind the escutcheon plate or found tile movement near the drain. That’s the part failing: the substrate or the waterproofing layer underneath, not always the tile itself.
Key Takeaways:
- We install Tremron-compatible bathroom remodels throughout Orange County, from Irvine to Mission Viejo, with written pricing up front.
- Typical installed cost: $9,000 – $28,000 based on the size of the wet area and how far the water damage has traveled.
- Pinpointing the failed layer before you retile is everything. Retiling over a bad substrate is a six-week redo.
- We’re an independent contractor, not a Tremron dealer. We work with their products because they’re structurally sound, but the Kingswell 365-Day Done Right Promise covers our install work regardless of whose product is on the walls.
Which Tremron Models This Applies To
Tremron doesn’t make a single “bathroom system” the way some fixture brands do. What Orange County homeowners actually run into is Tremron concrete and paver products used in and around bathrooms: shower curbs, bathroom thresholds, and occasionally whole shower floors built on their concrete pavers instead of a standard mud bed or foam pan. We’ve pulled apart showers in Irvine homes from the late 80s where the curbs were Tremron pavers cut to size and mortared in place.
Here’s the compatibility gotcha: a Tremron curb unit is not the same as their landscape paver, even when the dimensions look close. Tremron bathroom-adjacent products have a tighter dimensional tolerance and a smoother top surface because they’re meant to take a waterproof membrane and thin-set. If someone sold you a landscape paver for a shower curb, it’ll hold water in the wrong places and shift under tile weight.
When we match a replacement, we measure the existing unit’s thickness, the lip height, and whether the original installer notched it for a glass enclosure. For most Orange County rebuilds, a quality aftermarket curb rated for wet-area use works just as well as OEM, but if you’re keeping the original tile pattern, we’ll find the closest Tremron spec so the line heights line up.
Styles & brands we work with
Signs Your Tremron Bathroom Remodeling Is Failing
- Damp smell that comes back after cleaning. Water is sitting in the mortar bed or behind the curb. It won’t dry out on its own, and masking it with sealant just pushes the moisture sideways into the wall cavity.
- Grout cracking along the top edge of the curb. That’s movement. The curb is flexing or the substrate under it has softened. Every shower door cycle then works the crack wider.
- Tile pulling away from the face of the curb. Thin-set has lost its bond, usually because the concrete unit was never primed before tile went on. This is repairable, but only if the waterproofing behind it is still intact.
- Water staining the ceiling below the bathroom. You’re past the point of recaulking. The pan or the curb has a real leak, and we need to open the floor to see how far it traveled.
- The glass shower door won’t square up anymore. The curb settled or cracked. In Orange County’s soil, a shifting slab will telegraph through a shower curb faster than anywhere else in the house.

AfterReplacement Cost & What’s Included
A full Tremron-compatible bathroom remodel in Orange County runs $9,000 to $28,000. The spread comes down to three things: whether we’re rebuilding the shower pan and curb only, how much of the surrounding tile and drywall got wet, and whether the existing drain location still works with today’s code. A small guest bath that only needs curb replacement and a pan liner lines up around $9,000 to $12,000. A master bath with a rotted subfloor, new shower glass, and full tile runs toward the top of the range.
| Scope | Typical Orange County Cost |
|---|---|
| Curb replacement only | $3,000 – $8,500 |
| Small bathroom remodel (curb, pan, tile) | $9,000 – $12,000 |
| Full bathroom remodel with Tremron-compatible wet area | $14,000 – $28,000 |
Every number we quote includes parts, labor, demo, and disposal. You get the written price before we start, and the 365-Day Done Right Promise covers the install for a year after we finish. If it fails inside that window, we come back and fix it at no charge. No service call fee, no re-inspection charge.
DIY or Call Us?
You can check a few things yourself: run water along the curb and watch if it pools against the tile, press gently on the top row of grout to feel movement, and look for rust-colored drips under the pan. What you shouldn’t do is pull tile off to inspect what’s behind it. Once you break the waterproofing layer, you’ve turned a contained repair into a full rebuild.
Shower pans and curbs fail in layers, and the failure you can see is usually one step behind the failure that’s doing the actual damage. We’ve reworked too many Orange County bathrooms where a homeowner peeled up a few tiles, found soggy backer board, and now the whole floor has to come out. If you’re unsure whether it’s a cosmetic crack or a structural one, call (424) 541-1701 and we’ll tell you what we’d look for before we even schedule the visit. Give you the number first, then pick up the tool.
FAQs
A properly installed Tremron-compatible shower pan and curb should last 20 to 30 years in Orange County’s climate, though we usually see failures at 10 to 15 years when the original installer skipped the primer or the waterproofing membrane. The real lifespan shortener here is our hard water, which eats at grout and forces moisture into the bed. Call (424) 541-1701 if your pan predates the 2000s; we can usually tell you what failed without opening it up.
Yes, if the crack is limited to the grout lines and the concrete unit itself is sound. We repoint the grout, re-waterproof the top surface, and reset the tile. If the concrete curb has actually cracked through, no patch will hold under the weight of a glass door, and we’ll recommend replacement. Call (424) 541-1701 for a straight answer, and we’ll send a written quote either way.
A curb-only replacement takes two to three working days including waterproofing cure time. A full bathroom remodel runs one to three weeks depending on how much demolition and drywall work got pulled into the scope. We give you a defined arrival window for every day we’re on site, not a vague “sometime this week.”
We stock standard curb units, pan liner material, thin-set, primer, and waterproofing membrane on our trucks, so most Orange County jobs don’t wait on supply. Specialty Tremron dimensions take a day or two from our local supplier. We also work with KraftMaid, Cambria, and Silestone products when a remodel extends beyond the wet area.
If your shower pan or curb is showing signs of failure, don’t wait for the ceiling below to tell you twice. Call (424) 541-1701 and we’ll schedule a walkthrough. You’ll get a written price before any work starts, and a written guarantee on whatever we install.
