Tamko Bathroom Remodeling: The Miami Owner’s Guide
If you’ve got a failing Tamko bathroom component, you’re likely looking at a full or partial remodel rather than a simple patch. We’ve handled Tamko-compatible bathroom remodels across Miami for years, with installed projects typically running $10,620 – $33,040 depending on scope, materials, and what’s hiding behind the walls. Most Tamko bathrooms we see in this market were builder-grade installs from the 1990s and early 2000s, which means water damage around the tub flange, failing grout lines, and subfloor rot under the tile are the usual culprits. The homeowner spots cracked grout, a soft spot near the toilet flange, or tiles popping loose, then discovers the waterproofing layer has been quietly failing for years.
We’re an independent remodeling contractor, not affiliated with Tamko directly, but we work with Tamko tubs, surrounds, and shower systems on a regular basis and know their installations inside out.
Which Tamko Models This Applies To
Tamko’s bathroom line includes their acrylic and gelcoat tubs, shower bases, and two-piece tub surrounds that were installed heavily in Miami tract housing from roughly 1985 through 2010. The model number matters more than you’d think. On Tamko tubs, you’ll find a stamped plate on the underside of the deck or along the apron; the part number starts with a letter code that indicates the series. The most common ones we encounter in Miami are the 5400 series tubs and the 60-inch one-piece surrounds, which measure 60″ x 30″ x 74″ nominally but often run a half-inch wider in production.
When we replace a Tamko component, we have two honest options: source a direct-match OEM part or install a quality equivalent. For tubs and shower pans, OEM matching is usually worth it because the drain location and flange height were designed for that specific unit. For trim, valves, and surrounds, we often recommend proven alternatives from Kohler or Moen, which carry longer warranties than the original Tamko hardware and offer better part availability here in Miami. Our suppliers stock the common Tamko replacement pans and surrounds locally, but discontinued color codes can take two to three weeks to source.

Signs Your Tamko Bathroom Remodeling Is Failing
- Hairline cracks radiating from the drain opening. This is classic flex fatigue. Over time, the subfloor settles slightly and the fiberglass pan bends under foot traffic. Each step opens a micro-crack a little more until water reaches the wood below. In Miami’s humidity, that moisture never fully dries.
- Tiles popping or sounding hollow when tapped. Sound hollow means the thinset has debonded from the substrate. Once water gets behind those tiles, the cement board starts wicking it outward and you’ll see staining at the baseboard or bubbling paint on drywall next to the shower.
- Soft spot in the subfloor near the tub or shower entry. This is the late-stage symptom. By the time you feel sponginess underfoot, the plywood has been saturated long enough to lose its structural integrity. We’ve opened floors in Coconut Grove homes where the joists were fine but the subfloor crumbled like wet cardboard.
- Musty or fungal smell that returns after cleaning. You’re smelling mold in the wall cavity. Not on the surface, not in the grout, but inside the wall where the Tamko surround’s caulk line has failed and bathroom moisture has been feeding growth for months.
- Grout cracks along the tub flange line. The tub flange is the lip that extends up behind the tile. When a Tamko tub shifts slightly over the years, the grout line at that seam cracks first. It’s the entry point for almost every water damage problem we find in Miami bathrooms.

AfterReplacement Cost & What’s Included
In Miami, a Tamko-related bathroom remodel typically runs $10,620 – $33,040 fully installed. Here’s what drives the number up or down:
- Small bathroom remodel: $5,900 – $14,160. This covers a direct tub or pan replacement, new surround, valve trim, and flooring in a typical 5′ x 8′ bathroom.
- Full bathroom remodel: $10,620 – $33,040. This is the complete gut: new Tamko tub or walk-in shower, tile from floor to ceiling, new vanity, new lighting, new toilet, and full waterproofing.
- Walk-in shower conversion: $5,310 – $14,160. Converting a Tamko tub to a walk-in shower with a tiled pan and glass enclosure.
Every one of these numbers is a written, fixed price before we start. Not an estimate range. Not a ballpark that changes after demo day. If we open the wall and find something unexpected, we stop, show you what we found, and agree on a change order in writing before moving forward. The 365-Day Done Right Promise covers the full job: if anything fails within a year, we come back and fix it at no charge. That’s in writing on every contract.
DIY or Call Us?
Replacing a Tamko tub, pan, or surround is not a weekend project. The demolition alone involves lifting a tub that weighs between 60 and 100 pounds out of a cavity with plumbing attached to it. If the drain line gets cracked during removal, you’re now doing plumbing repair inside your floor. If the waterproofing isn’t done exactly right, you’ll be tearing it out again in two years.
What you can safely do before calling us: shut off the water at the fixture stops, dry the area thoroughly, and take photos of the model plate so we know exactly what we’re matching. That’s useful. Everything after that, from drain removal to subfloor inspection, benefits from a trained set of hands. We send background-checked, uniformed technicians on every job, so you know who’s walking through your front door. Call (850) 988-7559 and we’ll give you a number first, then pick up the tools.
FAQs
A direct tub or pan replacement on a Tamko-compatible bathroom typically takes 3 to 5 working days. A full gut remodel with tile, glass, and new fixtures runs 2 to 4 weeks depending on material lead times and what we find when walls come open. We’ll give you a defined arrival window for every day of the project before work starts.
A cracked Tamko tub or pan can sometimes be patched, but the repair rarely lasts in Miami’s humidity cycle. Surface patches don’t address the flex that caused the crack, so they typically fail within a year. If you’re planning to stay in the home, replacement is the honest recommendation. If you need a short-term fix while budgeting, call us at (850) 988-7559 and we’ll tell you straight whether repair is a realistic option for your specific crack.
We keep common Tamko tubs, pans, and trim components available through our local supply partners, and we can typically have the part on site within a week. Discontinued color codes take longer. We’ll confirm availability and lead time before you commit to anything.
No. You get a written price before any work starts and that’s the number on the invoice. If we uncover hidden damage during demo, we stop, show you the issue, and get written approval on any change before proceeding. No surprises, no “it got more complicated” calls. That’s the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it.
If you’re dealing with a failed Tamko tub, cracking surround, or water damage from a shower that’s been leaking behind the tile, call (850) 988-7559. The estimate is free, it’s in writing, and you’ll talk to a real person when you call.
