American Standard Home Additions & ADU: The Orlando Owner’s Guide
American Standard home additions and ADU construction in Orlando typically run $45,000 – $130,000 installed depending on square footage, foundation type, and whether you’re adding a full kitchen or bath. We stock and install the American Standard-compatible fixtures and finishes that go into these projects, and we can usually start your build within 2 – 4 weeks of permit approval. Most homeowners call us when they realize their existing space won’t work anymore, or when they’ve priced a move and found it costs more than building what they actually need.

We’re an independent remodeling company in Orlando, not affiliated with American Standard directly, but we work with their product lines every week because they hold up in Florida’s humidity better than most.

Which American Standard Models This Applies To
American Standard doesn’t make “additions” as a single product. They make the plumbing fixtures, toilets, tubs, showers, and sinks that go into them, and the model numbers matter when you’re roughing in a new bath or kitchen. For a home addition with a bathroom, the most common lines we install are the American Standard Cadet and Champion toilet series, the Princeton and Cambridge tubs, and the Ovation or Gelcoat shower lines. For an ADU kitchen, we typically see the Pekoe or Colony faucet lines, which are built for high-use rental or in-law situations.
Here’s the compatibility gotcha most people miss: American Standard rough-in dimensions changed over the years. A Cadet 3 toilet needs a 12-inch rough-in, but some older models need 10 or 14 inches. If you’re planning an addition or ADU, tell us which fixture models you want before framing starts, because moving a drain line two inches after the slab is poured costs two thousand dollars. We verify model numbers against your framing plan before concrete ever gets poured, and that’s a step most Orlando contractors skip.
Signs Your American Standard Home Additions & ADU Is Failing
- Hairline cracks where the addition meets the original house. This usually means the foundation wasn’t tied correctly, or the soil under Orlando’s sandy substrate wasn’t compacted before the slab went in. It’s fixable, but it means the original contractor skipped a step.
- Doors that stick in summer and swing free in winter. Florida’s humidity makes framing lumber move. If the addition wasn’t built with the right moisture content, you’ll feel it in every door frame. We’re used to this in College Park, where the 1950s bungalows have framing that’s been breathing for seventy years.
- Water staining around the base of tubs or toilets. The American Standard fixture isn’t the problem; it’s the seal or the flange underneath it. A wax ring that wasn’t seated correctly, or a tub that wasn’t set in a proper mortar bed, will leak slowly until the subfloor gives out.
- Mold smell in the wall cavity behind a shower. American Standard’s Gelcoat showers are solid units, but if the cement board substrate (the moisture-resistant layer behind your tile or surround) wasn’t installed with a vapor barrier, Florida humidity will find its way in.
- Your electric bill climbs after the addition is finished. An undersized HVAC return, missing insulation batts, or a roofline that wasn’t vented correctly. It all adds up in an Orlando summer.

AfterReplacement Cost & What’s Included
In Orlando, a home addition runs $45,000 – $130,000 depending on size, finish level, and whether it’s a single-story bump-out or a full second-floor addition. An ADU (accessory dwelling unit) runs $90,000 – $220,000 because it includes its own kitchen, bath, and typically its own utility connections. A garage conversion lands at $30,000 – $80,000, which is often the most cost-effective way to add living space without changing your roofline or foundation.
Every number we give you is written down before work starts. Not an estimate range, not a verbal ballpark: a written number you can hold us to. That price includes the demolition, framing, plumbing rough-in, electrical, drywall, paint, trim, and the American Standard fixtures we agreed on. If the job needs more than we scoped, we tell you before we spend the money, not after. And every project carries the 365-Day Done Right Promise in writing: if it’s not done right, we make it right at no charge.

DIY or Call Us?

You can check a few things yourself: measure your existing doors to see if they still close square, look for water staining around fixture bases, and walk the exterior seam where the addition meets the house. That tells you what’s happening. Fixing it is a different job. Foundation ties, plumbing rough-ins, and electrical panel work are not weekend projects, and in Florida, most of this work requires permits and inspections. We pull permits on every addition and ADU we build in Orlando, and we scheredule the inspections before we close up any wall.
If you’ve got a failed addition or an ADU that’s giving you trouble, call (850) 427-6454. We’ll come look, tell you what’s actually wrong, and give you a written price before anyone picks up a tool. Trevor Nash founded this company on a simple idea: give you the number first, then pick up the tool.
FAQs
A single-story home addition typically takes 8 – 16 weeks from permit approval to final inspection, depending on size and finish level. An ADU runs 4 – 8 months because it includes separate plumbing, electrical, and usually its own water heater. Call (850) 427-6454 and we’ll give you a real timeline for your specific project, not a generic answer.
Yes, in many cases. Foundation settling can often be addressed with helical piers or slab jacking, and moisture problems usually come down to reflashing or re-sealing what was done wrong the first time. We’ll tell you honestly if it’s worth fixing or if tearing out and starting fresh costs less. Estimates are free.
We stock the most common American Standard Cadet, Champion, and Princeton lines, and we can order specific models from our trade suppliers in Orlando, usually within 3 – 5 business days. We also work with KraftMaid for cabinetry, Cambria and Silestone for countertops, and Kohler and Moen fixtures when the job calls for them. Tell us what you’re looking for and we’ll have it ready before the crew shows up.
Only if you change the scope. The written price we give you before work starts is the price on the invoice, unless you ask for something different mid-project. If we find something hidden behind a wall that we couldn’t have seen during the estimate, we stop and tell you before we spend another dime. That’s how we’ve done it since day one, and it’s written into the Kingswell Way that every Penhallow location follows.
