Tamko Bathroom Remodeling: The Los Angeles Owner’s Guide
Tamko bathroom remodeling in Los Angeles typically runs $10,620 to $33,040 for a full bathroom rebuild, with shower and tub-focused work landing between $4,130 and $14,160. We stock Tamko-compatible waterproofing, backer board, and shower system components on our trucks, so most replacements start the same week you call. What usually brings a Tamko owner to us is water where it shouldn’t be: grout that stays dark after it dries, a shower pan that flexes underfoot, or drywall staining below the tile line. Those are the signs a waterproofing layer has called it quits, and Los Angeles hard water doesn’t do failing shower systems any favors.
We’re an independent remodeling contractor, not a Tamko affiliate. That means we match what’s already in your walls without pushing a brand swap unless your existing setup genuinely needs one.
Which Tamko Models This Applies To
Tamko’s shower waterproofing and tile backer lines show up across a lot of Los Angeles bathroom builds from the last 15 years, often labeled under their Red Zone or ProLine series. The compatibility gotcha we see most: Tamko shower pans were sold in both 32×60 and 36×60 center-drain footprints, and a 32-inch pan will not telescope into a 36-inch opening without re-framing the curb. Before you order anything, shine a flashlight under the drain cover and read the stamp on the pan collar. That number is the only reliable way to match a replacement.
For waterproofing membrane work, OEM Tamko material holds up well, but we often recommend a quality aftermarket equivalent such as a sheet membrane from a major manufacturer when the OEM roll is backordered. The spec matters more than the label: we verify thickness in mils and seam-band compatibility before anything gets installed. If you’re unsure what series you have, our crew can identify it in about ten minutes on site.

Signs Your Tamko Bathroom Remodeling Is Failing
- Grout stays dark or develops rust-colored streaks after drying. Water is wicking behind the tile, and the waterproofing layer has been breached. In Los Angeles, hard mineral deposits accelerate this once a pinhole opens.
- Shower pan flexes or squeaks when you step in. The mortar bed beneath the pan has crumbled or the pan wasn’t set on a level substrate. Flex equals eventual cracks, and cracks in a pan are a full replacement, not a patch.
- Musty smell that doesn’t leave after cleaning. That’s moisture trapped in the wall cavity. By the time you smell it, the framing behind the tile is already wicking water.
- Tile feels hollow when tapped, or a single tile has loosened. The thin-set bond is failing, usually because moisture got behind it. One loose tile is rarely the whole story.
- Water stains on the ceiling below a second-floor bath. The waterproofing at the drain collar or the pan corners has failed. This is the one that can’t wait: the water is already moving through your framing.

AfterReplacement Cost & What’s Included
Here’s how Tamko bathroom remodeling pricing lands in Los Angeles:
- Full bathroom remodel with Tamko waterproofing: $10,620 – $33,040
- Walk-in shower rebuild (Tamko pan and membrane): $5,310 – $14,160
- Tub-to-shower conversion: $4,130 – $11,800
- Shower pan replacement only: $3,540 – $10,030
The spread comes down to three things: whether demo exposes rotted framing (we give you a written price before work starts, so there’s no surprise invoice if we find it), the tile you choose for the finish layer, and whether plumbing needs to move. Every quote includes parts, labor, debris removal, and our written guarantee covering the installation for 365 days from the completion date. We hand you a line-item price before a single tool comes off the truck.
DIY or Call Us?
You can safely check three things yourself: read the stamp under the drain cover to identify your pan model, document stains or loose tile with photos, and keep the area dry in the meantime. What you should not do is open up the waterproofing layer. Once a Tamko membrane is compromised, cutting into it without knowing where the water has traveled just moves the problem deeper into the framing. The risk isn’t just a bad tile job; it’s structural rot you can’t see. If you’ve got signs of a failing Tamko bath, call (803) 680-2547 and we’ll put a name and photo on who’s coming to look at it.
FAQs
A correctly installed Tamko shower system in Los Angeles should hold for 20 to 25 years, though our hard water and the valley’s dry-summer/wet-winter cycle stress sealant joints at the 15-year mark. We see most failures start where the membrane turns at the curb or at the drain collar, not in the field of the membrane itself. If you’re past year 15 and noticing grout behavior changes, that’s your early warning. Call (803) 680-2547 for an inspection.
No repair will outlast the cost of a proper replacement once the pan collar or membrane is breached. Patches might buy you a dry season, but Los Angeles humidity swings mean the patch fails again, usually behind the tile where you can’t see it. We quote the replacement honestly and don’t sell patch jobs we wouldn’t put in our own homes. Estimates are free.
A full Tamko bathroom remodel with us typically runs 10 to 15 working days from demo to final walkthrough, assuming we’re not moving plumbing or reframing. Shower pan swaps usually run 5 to 7 working days. We give you a written schedule with the written price, so you know both before anyone picks up a hammer.
We stock the common Tamko pan sizes (32×60 and 36×60 center drain), backer board, and membrane seam kits on our trucks for Los Angeles jobs. Specialty sizes or specific series trim parts we source direct within 3 to 5 business days. You’ll know which applies to your job before we start, in writing.
Know who’s coming, know what it costs, know it’s backed up – everything else is just noise.
