Therma-Tru Bathroom Remodeling: The Fort Lauderdale Owner’s Guide
Therma-Tru bathroom remodeling in Fort Lauderdale typically runs $9,000 – $28,000 installed, depending on the size of the bathroom, the condition of the plumbing and framing behind the walls, and the fixtures you choose. We stock Therma-Tru-compatible entry and interior door systems, and our crews install them as part of full bathroom remodels across Fort Lauderdale every month. The most common way homeowners discover a problem: they notice the door no longer seals tight against the threshold, the corner joints have started to separate in the humidity, or the finish is blistering around the bottom rail.
If you’ve got a Therma-Tru door in a bathroom that’s starting to show its age, or you’re planning a remodel and want the new door to hold up to South Florida moisture, this page covers what you need to know before you spend a dollar.
Which Therma-Tru Models This Applies To
Therma-Tru makes a wide range of fiberglass and steel entry doors, and while most people think of them for front entries, plenty of Fort Lauderdale homes use them in bathrooms opening to patios, pool decks, or side yards. The bathroom-adjacent lines we see most often are the Classic-Craft, Fiber-Classic, and Smooth-Star series, along with their glass-insert patio door configurations.
Here’s the compatibility gotcha most homeowners run into: Therma-Tru doors are sold as a system, not just a slab. The frame, sill, weatherstrip, and corner pads are engineered to work together, and mixing an aftermarket sill or generic weatherstrip with an OEM slab voids the fit you paid for. When we match a replacement part, we pull the door’s serial number (typically stamped on the hinge edge of the slab or on a silver label inside the frame) and verify it against Therma-Tru’s spec sheets. OEM parts cost more than aftermarket equivalents, but for doors exposed to Fort Lauderdale’s salt air and nine months of humidity, the OEM corner seal pads and composite sill pans hold up measurably longer. We keep both options on the truck and give you the price difference before we order.
Styles & brands we work with
Signs Your Therma-Tru Bathroom Remodeling Is Failing
- Condensation or fogging between insulated glass panes. The door’s insulating glass unit has lost its seal. South Florida’s humidity makes failed seals show up faster than they would in a dry climate – once the desiccant inside the glass is saturated, the fog never clears on its own.
- Visible daylight around the door’s perimeter when closed. The weatherstrip has compressed or the frame has settled out of square. A door that doesn’t seal lets conditioned air escape and lets Fort Lauderdale’s humid outdoor air pour in, which drives up your AC bill and invites mold behind the casing.
- The bottom sweep is cracked, curled, or missing chunks. Therma-Tru’s sweep designs vary by series, and a generic replacement from a hardware store rarely fits the kerf channel correctly. We see homeowners try this fix once, watch the sweep fall off in a week, and then call us.
- Corner joints on the frame are pulling apart. This is common on older Classic-Craft units in bathrooms where shower steam has been hitting the frame for years. The fiberglass can flex, but the corner joinery is structural – if it’s separating, the frame needs professional attention, not caulk.
- The finish is blistering, peeling, or showing rust streaks near the bottom rail. Fort Lauderdale’s salt air is unforgiving on steel doors that have even a hairline paint scratch. Once moisture gets under the finish, rust spreads quickly. Therma-Tru’s fiberglass lines resist this far better than steel, which is a big reason we recommend them for bathroom-to-pool transitions.

AfterReplacement Cost & What’s Included
A Therma-Tru-compatible bathroom remodel in Fort Lauderdale ranges from $9,000 to $28,000, installed. The spread comes down to three things: bathroom square footage, the condition of the substrate (the moisture-resistant layer behind your tile), and fixture grade. A compact 5×8 bathroom with a fiberglass surround and builder-grade vanity lands near the bottom of that range. A primary bath with a walk-in shower, custom vanity, and a new Therma-Tru patio door opening to a pool deck lands near the top.
Our written price includes the door slab, frame, sill, hardware, all labor, debris removal, and the 365-Day Done Right Promise. We don’t hand you a verbal ballpark and then “discover” issues after demo day – that’s exactly what burned you before, and it’s the reason we put a written number in your hand before any work starts. If the door goes in wrong, doesn’t seal, or the hardware fails inside the guarantee window, we come back and fix it at no charge. No re-inspection fee, no service call charge.
DIY or Call Us?
What an owner can safely check: clean the weatherstrip with a damp cloth and make sure the sweep isn’t packed with sand or leaves; tighten loose hinge screws with a screwdriver; note whether the door rubs at the top or the latch side. Those observations help us quote faster.
Where DIY goes wrong: any structural work on a Therma-Tru door system. These doors aren’t finished-door slabs you can pop off and plane down like a wood interior door. The fiberglass skin is thin, the factory corner joints are load-bearing, and the sill pan integrates with the home’s flashing. Cutting into the slab or forcing the frame will cost more to fix than the original problem. If the door no longer seals or the frame has moved, call (754) 551-2922 and we’ll send a background-checked, uniformed technician to assess it. Tell me what you need, I’ll tell you what it costs – then we’ll get it done.
FAQs
With proper installation and a good finish, a Therma-Tru fiberglass door in a Fort Lauderdale bathroom typically lasts 20 – 30 years, but the weatherstrip and sweep need replacement every 3 – 5 years due to constant humidity exposure. The door slab itself rarely fails first – it’s the service parts around it. Call (754) 551-2922 if your seal is gone and you want an honest assessment of whether to repair or replace.
Yes, in most cases where the slab and frame are structurally sound, we can replace the weatherstrip, sweep, sill cap, or insulated glass unit individually. If the frame corners have separated or the sill pan has rotted the subfloor beneath it, replacement is the honest answer. We’ll give you a written quote for either path before you choose.
A straightforward replacement of an existing Therma-Tru door in its current opening usually takes one full day on site. If the surrounding framing, drywall, or tile needs rework because of water damage, plan for two to three days depending on what we find behind the walls.
We stock common Therma-Tru weatherstrip, sweeps, and sill caps on our trucks for Classic-Craft, Fiber-Classic, and Smooth-Star series doors. Uncommon glass units or color-matched frame parts are ordered direct and typically arrive within 5 – 7 business days, which we factor into the written schedule we give you up front.
No. The written price you receive before work begins is the number on the invoice. The only exception is if we uncover rotted framing or a failed sill pan that was impossible to see before demo – and if that happens, we stop, show you what we found, give you a written change order, and wait for your approval before doing anything else. No surprises, no ballooning.
We do. Alongside Therma-Tru, we regularly install KraftMaid cabinetry, Cambria quartz countertops, and Silestone surfaces in Fort Lauderdale bathrooms. The same written-price, written-guarantee standard applies to every brand we carry.
If your Therma-Tru bathroom door is failing, or you’re planning a full remodel and want the door done once, call Penhallow Remodeling Fort Lauderdale at (754) 551-2922.
