Tremron Bathroom Remodeling: The Los Angeles Owner’s Guide
Tremron bathroom remodeling in Los Angeles typically runs $10,620 – $33,040 for a full replacement, and we can usually start within two weeks of your written estimate. We’re an independent contractor, not affiliated with Tremron, but we stock Tremron-compatible materials in our Los Angeles warehouse, so if a part has failed you aren’t waiting on a special order from out of state. Most owners reach out after noticing cracked tile around a curb, water staining on the ceiling below, or grout that won’t stop crumbling no matter how many times it’s patched. The part itself rarely announces it’s failing; the mess around it does.
Which Tremron Models This Applies To
Tremron bathroom products fall into a few distinct lines, and the part compatibility matters more than the brand name on the original box. We see three main categories across Los Angeles homes: Tremron shower pans and curbs (the sloped base under the tile), Tremron tub and shower surrounds (the molded wall panels), and Tremron floor tile systems used in wet areas. Here’s the gotcha that trips up most owners: Tremron pan dimensions are nominal, not actual. A pan labeled 60 inches is often 59.75 or 60.25 once you account for the flange. That quarter-inch difference is why a “universal” replacement pan from a big-box store rarely seats correctly against the drain and walls. If you’re checking your existing pan, measure from the back of the flange to the front edge, not wall-to-wall. We match the exact model by taking measurements and, when the original install left a label behind the escutcheon plate, reading the stamped number directly.
On OEM versus aftermarket: for pans and curbs, Tremron’s original parts are hard to source direct in Los Angeles and usually cost 20 – 30% more than quality equivalents like Schluter or Oatey, which we keep on the truck. The material difference is meaningful: Tremron pans are typically fiberglass-reinforced acrylic with a gel coat, while the aftermarket options we use are expanded polystyrene core with waterproof membrane. Both work. The membrane system actually tiles flatter. For tile and grout, brand doesn’t affect performance much; what matters is Glendale’s hard water and the alkaline content, which we’ll get to below.
Styles & brands we work with
Signs Your Tremron Bathroom Remodeling Is Failing
- Grout that crumbles within a month of patching. This usually means the pan or substrate is flexing underneath. Grout doesn’t fail on its own in a stable system. If you patch it and it cracks again in the same spot, the part underneath moved, and no grout will fix that.
- Water staining on the ceiling of the room below. That’s the telltale of a pan membrane failure or a drain clamp that came loose. By the time the stain appears, water has been sitting in the subfloor for weeks or months in Los Angeles’s dry climate, because it evaporates before it pools visibly.
- A soft or spongy spot in the floor outside the shower. This is rotted subfloor from a slow leak at the curb or threshold. The Tremron curb is a separate part from the pan, and the seam between them is the most common failure point. Owners standing on it feel a slight give and assume it’s the tile, but it’s the framing underneath.
- Mold recurring in the same grout lines after cleaning. Water is wicking into the back of the tile or the pan flange and never drying out. In Sherman Oaks and Studio City, we see this consistently in bathrooms with poor ventilation fans. The part isn’t necessarily failed, but the system behind it is holding moisture.
- A drain that no longer sits flush, or rocks when you stand on it. The pan shifted or the subfloor settled. This is more common in older Los Angeles homes built on pier-and-beam foundations before 1970. The Tremron pan itself may still be intact, but it needs to be reset or the drain re-clamped.

AfterReplacement Cost & What’s Included
Here’s what we write on estimates across Los Angeles, from Highland Park to Westchester:
- Shower pan replacement with new tile floor: $3,540 – $7,680
- Full pan, curb, and lower wall rebuild: $6,490 – $11,800
- Complete Tremron bathroom remodel (pan, walls, floor, fixtures): $10,620 – $33,040
- Tub-to-shower conversion with new pan: $4,130 – $11,800
What drives the spread within Los Angeles is access, not materials. A bathroom on an upper floor of a 1920s bungalow with a narrow stairwell costs more because every bucket of mortar and tray of tile gets carried by hand. A single-story home with a door to the outside runs toward the lower end. Every line item is written down before work starts: parts, labor, haul-off, waterproofing, and the guarantee. No verbal estimate that grows later. If we find unexpected rot when the old pan comes out, we stop, show you photos, and put the repair in writing before we proceed. That’s the rule, not an exception.
All work carries our 365-Day Done Right Promise. If anything we touched fails within a year of the completion date, we return and make it right at no cost to you. No dispute process, no conditions.
DIY or Call Us?
Here’s the honest split. You can safely identify the problem: check your subfloor from below if you have a crawlspace, look for mineral deposits around the drain, mark the stained grout lines with painter’s tape and watch whether they reappear after cleaning. Your job is knowing what’s wrong, not fixing it. A shower pan replacement involves removing the bottom rows of tile, cutting out a failed pan, inspecting subfloor for rot, re-laying a new pan with proper slope, and then waterproofing the seams. If the subfloor is rotted, you’re now doing structural framing. That’s not a weekend project and the cost of getting it wrong is water quietly destroying the framing you can’t see.
We’ve fixed enough DIY pan replacements in the San Fernando Valley to say this plainly: the most expensive bathroom remodels in Los Angeles are the second ones. Call (803) 680-2547 and we’ll put a written estimate in front of you before you decide anything.
FAQs
A correctly installed Tremron pan lasts 15 – 25 years in Los Angeles, but the tile and grout on top of it often need attention at the 10 – 12 year mark because of our hard water and frequent small seismic shifts. Call (803) 680-2547 and we’ll inspect yours and tell you whether it’s a repair or a replacement.
Small surface cracks in the gel coat can sometimes be sealed, but a crack that goes through the pan body cannot be reliably patched because flex will reopen it within months. We’ll tell you which one you have after looking at it, and the estimate is free.
A pan and lower-wall replacement takes 4 – 7 working days in Los Angeles; a full Tremron bathroom remodel runs 2 – 4 weeks depending on access, plumbing moves, and whether we find rot in the subfloor. We’ll put the schedule in writing with your price.
We stock Tremron-compatible pans, curbs, waterproofing, and trim in our Los Angeles warehouse, so most jobs start without a parts wait. For a matched Tremron OEM part, we give you the lead time in writing before work begins. Call (803) 680-2547 and we’ll check inventory for your exact model.
Know who’s coming, know what it costs, know it’s backed up – everything else is just noise.
