Tremron Bathroom Remodeling: The West Covina Owner’s Guide
Tremron bathroom remodeling in West Covina typically runs $9,000 to $28,000 installed, depending on the scope and the condition of what’s behind the walls. Most homeowners call us after a specific failure: a shower pan that’s been leaking into the subfloor, tile that’s cracked along the pan line, or grout that won’t stay sealed no matter how many times it’s re-done. The fix is rarely the $30 tube of caulk you hope it is. It’s usually the waterproofing system underneath, which means opening the pan, checking the slope, and rebuilding it so water actually goes where it’s supposed to.
We carry and install Tremron-compatible shower pans, curbs, benches, and niches, and we match them to the waterproofing systems already in your home. If you’re not sure whether the part that failed is a Tremron original or a copy, we can tell you by looking at the underside markings and the drain collar fit before we quote a number. That’s what this page is for: giving you the real picture before anyone swings a hammer.
Which Tremron Models This Applies To
Tremron makes prefabricated shower pans, curbs, and niche units in a few standard series: the Classic line (basic rectangular pans with a center drain), the Neo-Angle series (corner units with a 45-degree front), and the Barrier-Free line (low-profile pans designed for curbless entry). Each has different drain placement and different flange heights, and that’s where the compatibility gotcha lives. A Classic pan’s drain collar sits about 1/2 inch higher than a Barrier-Free pan’s, so if you swap one for the other without adjusting the subfloor pitch, you’ll get standing water in the corners within weeks.
Here’s how to identify what you have: pull the drain grate and look for the molded serial stamp on the pan body near the drain opening. Tremron stamps the series name and a two-digit year code. If you can’t find it, measure from the drain center to the nearest wall – Classic pans are typically 30×60 with the drain centered, Neo-Angle pans are 36×36 or 38×38 with a corner drain, and Barrier-Free pans run 32×60 with an offset drain at the front edge. We keep all three series on the truck in the most common West Covina sizes, so we can usually swap a failed pan the same day we cut the old one out.
On the OEM-versus-aftermarket question: Tremron’s original pans are solid acrylic with fiberglass backing, and they hold up well in our climate. The knockoffs you’ll find at big-box stores are thinner – about 1/8 inch less material – and they flex underfoot, which cracks grout lines within the first year. We install OEM Tremron pans whenever they’re available in the size you need. When they’re discontinued or backordered, we use a US-made equivalent with the same flange height and reinforce the subfloor so the thinner material doesn’t become a problem. We’ll tell you which one you’re getting and why, in writing, before you pay for anything.

Signs Your Tremron Bathroom Remodeling Is Failing
Here’s what we see in West Covina homes, from the South Hills area down to the flats near the 10:
- Grout cracking at the pan-to-wall seam. The pan is flexing because the mortar bed underneath wasn’t set correctly or has broken down. Re-grouting alone won’t fix it – the movement just cracks the new grout within months.
- Musty smell that comes back after cleaning. Water is sitting where it shouldn’t be, usually between the pan and the subfloor or behind the wall board. In West Covina’s dry summers, the smell fades; in the rainy season or after heavy shower use, it returns.
- Discoloration on the ceiling below the bathroom. This means water has already made it through the subfloor. By the time you see the stain, the leak has been active for a while and the framing may be affected.
- Loose or “spongy” feeling tiles on the shower floor. The waterproof layer beneath the tile has failed and the mortar is saturated. This is the most direct sign that the pan or the waterproofing above it has to come out.
- Standing water in the corners two hours after a shower. The pan’s slope wasn’t pitched correctly to begin with, or the subfloor has settled. Tremron pans are pre-pitched at the factory, but the subfloor underneath has to be level or the pan won’t drain.

AfterReplacement Cost & What’s Included
In West Covina, a Tremron pan replacement with new waterproofing, tile, and fixtures typically lands between $9,000 and $28,000. The spread depends on three things: the size of the shower, what we find when we open the walls, and whether you’re reusing fixtures or replacing them. A straight pan swap in a 3×5 shower with no hidden damage runs at the lower end. A full tear-out with subfloor repair, new valve plumbing, and a custom tile surround runs toward the top.
Here’s what breaks the price down:
- Demo and haul-away: $600 – $1,200
- Tremron pan, curb, and drain assembly: $900 – $2,200
- Waterproofing system (Schluter or equivalent membrane, corners, sealant): $800 – $1,800
- Mortar bed and subfloor leveling: $700 – $1,500
- Tile and setting labor (walls and floor): $3,500 – $9,000
- Valve, trim, and shower head (Kohler, Moen, or Grohe): $600 – $2,500
- Permit and inspection: $400 – $800
Every line item is in writing before we start. The price we hand you is the price you pay – no change orders because we “found something” unless you approve it first in writing. Our 365-Day Done Right Promise covers the full installation for a year after we close the job. If it’s not done right, we make it right, and that’s also in writing.
DIY or Call Us?
You can safely check a few things before you call anyone: pull the drain grate and look for the Tremron stamp, test the shower floor for soft spots with your heel, and check the ceiling below for stains. Those three observations help us quote accurately over the phone.
The actual replacement is not a weekend job, and here’s the honest reason: a shower pan replacement means removing tile, cutting out the old pan, inspecting the subfloor, leveling it, setting the new pan in fresh mortar, waterproofing the seams, and re-tiling – all before you can run water. If the subfloor has rot from the leak, that’s framing work, and getting it wrong means your new Tremron pan cracks within the first year. We’ve pulled pans out of West Covina homes where the homeowner’s “quick fix” left the drain improperly seated and the entire floor had to come out anyway. Call us at (341) 217-4204 before you pick up a pry bar. The estimate is free.
FAQs
A properly installed Tremron pan lasts 15 to 25 years in our climate. The failure we see most often in West Covina is actually the waterproofing above the pan, not the pan itself. Hard water from the local supply slowly degrades caulk and grout, and once water gets behind the tile, the pan underneath can become the scapegoat for a leak it didn’t cause. Call (341) 217-4204 and we’ll tell you whether you need a pan or just a waterproofing reset.
If the pan itself is cracked, no – an acrylic pan with a structural crack will keep flexing and leaking. If the issue is a failed seal at the drain collar or the perimeter seam, a repair is sometimes possible, but you’re extending the life by a couple of years at best. We’ll tell you which situation you’re in before we quote anything.
Most pan-only replacements in West Covina take two to three working days from demo to first shower. A full shower rebuild with tile, waterproofing, and plumbing runs four to six working days. We’ll give you a day-by-day schedule in writing before we start, and you’ll get photo updates as we go under The Relay Visibility Guarantee.
We keep the most common West Covina sizes in stock: Classic 30×60 and 32×60, Neo-Angle 36×36 and 38×38, and Barrier-Free 32×60. Less common sizes and custom colors are ordered from Tremron’s California distributor and typically arrive in three to five business days. Call (341) 217-4204 with your measurements and we’ll tell you the lead time before you commit to anything.
If you’ve got a Tremron shower that’s leaking, cracked, or just looks wrong, call Sawyer Remodel West Covina at (341) 217-4204.
