Delta Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Delta does not manufacture home additions or ADUs. What you’re dealing with is a Delta fixture or component inside an addition or accessory dwelling unit that has failed, or you’re planning a Delta-equipped addition and need to know what the parts will cost and who can handle the work. Our team at Mason Remodeling Co Fort Lauderdale installs and services Delta fixtures across Fort Lauderdale additions and ADUs every week. A full home addition in Fort Lauderdale runs $45,000 to $130,000, while a complete ADU construction lands between $90,000 and $220,000. If you have a failed Delta part inside an existing structure, the typical repair is a fraction of that and usually handled in a single visit.
The most common way Fort Lauderdale homeowners find us: a Delta shower valve starts dripping inside a new ADU bathroom, a Delta kitchen faucet loses pressure in an addition, or a Delta tub spout pulls clean off the wall. Sometimes it’s a Delta toilet fill valve that won’t stop running. The part failed. The room is otherwise fine. You don’t need a whole remodel, you need the right Delta part matched to your model and installed by someone who knows what they’re looking at.
Key Takeaways
- We stock common Delta cartridges, valves, trim kits, and aerators on our trucks for same-visit replacement in Fort Lauderdale.

- Isaac Pruett has spent nearly two decades running addition and remodel projects across South Florida, including Victoria Park and surrounding Fort Lauderdale neighborhoods.
- Written price before we start. Every time. No verbal estimates that grow on the final bill.
Which Delta Models This Applies To
Delta makes hundreds of faucet, shower, and toilet components, and the compatibility gotcha is this: a Delta cartridge from a 2005 Monitor series shower valve will not fit a 2019 MultiChoice valve, even though both say “Delta” on the trim plate. You cannot identify the right part from a photo of the handle alone. You need the model number off the valve body, which usually means pulling the trim plate. On Delta kitchen faucets, the model number is printed on a tag under the sink, often wrapped around the supply line or stuck to the base of the faucet body.
For OEM versus aftermarket: Delta’s factory parts carry a lifetime warranty on the cartridge and finish for original purchasers. That’s real and worth using. But Delta installs proprietary seating and stop components on some series, and a generic aftermarket cartridge can fit tight, drip slowly from day one, or void the warranty if it damages the valve body. We stock OEM Delta cartridges for the Monitor 13/14/17 series, MultiChoice universal valves, and the common RP50587 and RP19804 pressure balance systems. If a quality aftermarket equivalent exists and we’ve seen it hold up in South Florida water conditions, we’ll tell you that too and price both.
Styles & brands we work with
Signs Your Delta Home Additions & ADU Is Failing
- Drip from the tub spout or shower head after the water is off. This is almost always a worn Delta cartridge or a failed seat and spring in the valve body. Fort Lauderdale’s hard water accelerates mineral buildup on the cartridge face, and the rubber seats harden faster here than in softer-water cities. Left alone, the drip becomes steady and water bills climb.
- Handle turns stiff or won’t return to center. Mineral scaling inside the valve body or a swelling cartridge cause this. Forcing the handle is how the stem shears off, and then you’re replacing the whole rough-in valve, not just the cartridge. That’s a wall-open repair.
- Water temperature swings while showering. The Delta pressure balance spool has stopped compensating. In older additions, the original valve may not be code-compliant with current anti-scald requirements, and this is the symptom that tells you it’s time.
- Low flow from a Delta kitchen or bath faucet, but good pressure elsewhere. The aerator is usually clogged with sediment, or the cartridge inlet screens are packed with the same. Easy fix if caught early. Ignoring it strains the cartridge and shortens its life.
- Water seeping from the base of the spout or around the trim plate. This points to a failed O-ring or torn gasket behind the trim. In Fort Lauderdale’s humidity, the gaskets degrade a little faster than dry climates, and the seepage shows up as staining on the wall behind the fixture.

AfterReplacement Cost & What’s Included
For a Delta part swap inside an existing Fort Lauderdale addition or ADU, you’re looking at $150 to $600 installed, depending on the part and access. A simple aerator or cartridge replacement on an accessible valve runs at the low end. A shower valve rough-in replacement that requires opening drywall and re-tiling around the valve runs $700 to $2,000. We don’t hide that range from you. You get the part number, the line-item price, and the labor broken out in writing before we touch a wrench.
| Delta Service | Fort Lauderdale Installed Price |
|---|---|
| Delta cartridge replacement (standard valve) | $150 – $350 |
| Delta RP50587 / RP19804 cartridge replacement | $180 – $400 |
| Delta kitchen faucet install or swap | $200 – $500 |
| Delta shower trim kit installation | $250 – $600 |

Every replacement is covered by our written guarantee for 365 days from the completion date. If the part we installed fails inside that year, we come back and fix it at no charge. No dispute process, no conditions. We also carry KraftMaid, Cambria, and Silestone lines for additions and ADUs where the fixture update turns into a broader refresh.
DIY or Call Us?
You can safely check the model number. Pulling the trim plate to read the valve body is fine if the water is off and you’re not forcing anything. Beyond that, Delta valve work goes wrong fast. The cartridge retainer clips break. The set screws strip. And on any valve where you’re opening the wall or touching supply lines, if you get it wrong, you’re flooding the room below. In a second-story ADU in Fort Lauderdale, that’s your tenant’s ceiling, your drywall, your insurance deductible. For any DIY repair beyond the aerator, call (754) 354-3720. A live person answers, every time, and we’ll tell you honestly whether this is a one-part fix or something bigger.
FAQs
Delta cartridges typically last 8 to 15 years in South Florida, but hard water can cut that to 5 to 8 years without a softener or filtration. The pressure balance spool and rubber seats usually fail first. Call (754) 354-3720 if you’re seeing any drip or temperature swing, and we’ll give you an honest read on what’s left in that valve.
Yes, most Delta shower valves can be repaired with a cartridge and seat-and-spring replacement, which runs $150 to $350 in Fort Lauderdale. Replacement of the full rough-in valve is only needed when the valve body itself is cracked, badly scaled, or not code-compliant. Call (754) 354-3720 and we’ll tell you which situation you’re in before you spend a dollar.
A standard cartridge or aerator replacement takes 30 to 60 minutes. A shower rough-in valve replacement with drywall and tile work takes a full day or two, depending on the surround. We’ll put the timeline in writing with the price.
