American Standard Home Additions & ADU Nationwide

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.

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.

Replacement 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.
