Sweat Decks pillar guide is worth evaluating through the homeowner’s real week, not a perfect catalog photo. The best setup is the one that gets used, stays safe, and does not become a maintenance headache.

Meta description: Remodeling Magazine’s Cost vs Value Report tells one story. Appraiser interviews and Zillow listing data tell a more useful one. Here is which 2026 home improvements actually return capital and which ones just feel like they should.
Three Financial Effects, Not One
Last October I sat across from Mike Torren, a residential appraiser in Lakewood, Colorado, at a coffee shop on Wadsworth Boulevard. Mike has reviewed roughly 6,000 appraisal files over 22 years. I asked him what homeowners get wrong about “ROI.” He didn’t even let me finish the question.
“They show me an invoice for $82,000 and ask why I only gave them $38,000 in value. Because that’s what the comps say, and I don’t care about their invoice.”
That exchange captures the central misunderstanding behind every “best home improvements for resale value” list on the internet. A home improvement does not “pay back” in one number. It produces three separate financial effects, and confusing them is how people dump $80,000 into a kitchen that nets them $40,000 at closing.
The three effects:
- Appraised value impact at refinance or sale, the number Mike writes down based on paired sales.
- Listing premium, what a buyer is willing to pay above comparable homes that lack the feature.
- Holding utility, the unmeasured benefit you get from using the thing for years before you sell.
Remodeling Magazine’s Cost vs Value Report, which I’ll reference throughout, measures only the first effect at the time of sale and only at a national average. The 2025 edition put nationwide average resale value recovery at 67.6 percent across all projects studied. That number hides massive regional and category variance.
Here’s what the 2026 picture actually looks like.
Exteriors Win. They Always Win.
The Cost vs Value Report has put garage door replacement at the top, or nearly, for over a decade. The 2025 edition reported 193.9 percent cost recouped at resale for a midrange garage door swap. Average project cost: about $4,500.
Nobody walks through a home thinking about garage doors. But the door is high curb-appeal-per-dollar and the labor is low. Steel insulated doors with carriage-style hardware photograph well in listings. Listing photo quality drives showings. Showings drive offers. It’s an ugly, boring improvement, and it works.
Manufactured stone veneer on a facade returned 153.2 percent at an average project cost around $11,000. Same mechanism: curb appeal, captured in the first listing photo, processed by a buyer in under three seconds. The caveat is execution. Bad veneer work, especially around drip edges and window returns, looks worse than bare siding. This is not a job for a contractor who hasn’t done it before.
A midrange steel entry door came in at 188 percent recouped. Cost average roughly $2,400. Same logic. Curb appeal, photographable, energy efficiency story for the buyer.
Three out of three of the top resale ROI projects are exterior. That is not coincidence. Buyers form opinions before they cross the threshold. The boring truth is that the most effective $10,000 you can spend on your home is probably visible from the street.
The Kitchen Trap
A midrange minor kitchen remodel (refacing cabinets, new countertops, refreshed appliances, paint) returned about 96 percent of cost at resale. The major kitchen remodel returned 49 percent.
Read those numbers again. The gap is the entire lesson.
A minor remodel keeps the layout, the plumbing, the electrical, and the cabinet boxes. You’re spending $30,000 on visible surfaces. A major remodel demolishes the cabinet boxes, often moves a wall, and pulls you into permits and structural decisions. You spend $80,000 and the appraiser values it at perhaps half that, because Mike down in Lakewood doesn’t care about your waterfall island. He cares about what the house across the street sold for.
Almost every homeowner who calls a kitchen designer wants the major remodel. Almost every appraiser will tell you the minor remodel is the better financial decision. The kitchen renovation industry depends on that disconnect.
Siding is worth mentioning here too. Fiber cement returned 88 percent in the 2025 report. Vinyl returned 80 percent. The marginal cost of fiber cement is roughly 25 percent more than vinyl. If you plan to sell within five years, vinyl is the better ROI. If you plan to hold ten-plus years, the maintenance differential favors fiber cement. Simple math, but people rarely run it.
Wood decks (pressure-treated) returned 83 percent. Composite returned 68 percent. Both numbers are healthy enough that decks remain sensible in nearly any climate where outdoor living actually gets used. One 2026 footnote: buyers in the Mountain West and Pacific Northwest now expect a deck or covered outdoor area. In those regions the listing premium effect outpaces the appraisal effect, which the Cost vs Value Report doesn’t capture.
The Wellness Build Nobody Modeled
Here’s where the standard reports fall apart. Outdoor wellness structures (saunas, cold plunges, covered patio rooms with hearths) didn’t appear in the Cost vs Value Report as a category until 2023 and still aren’t broken out cleanly.
Two data points worth flagging.
First, Zillow’s 2024 Consumer Housing Trends Report found that listings mentioning “sauna” sold for an average premium of roughly 2.6 percent over comparable listings without that keyword, controlling for square footage and zip code. The 2025 update widened that to 3.1 percent. For a $900,000 home, that’s $27,000 at the median.
Second, NAR’s Profile of Home Buyers and Sellers shows wellness amenities as one of the top three rising “must have” categories for buyers 35 to 55 with household incomes above $200,000.
That is not a representative national figure. It’s a high-income, recovery-culture demographic. But it’s a demographic with disproportionate market-moving purchasing power in the homes where these features actually get installed.
For homeowners in that bracket considering an outdoor sauna in the $25,000 to $65,000 installed range, the math looks roughly like this:
- Installed cost: $35,000 (midrange cedar cabin, electrical, foundation, permit).
- Appraisal lift: typically 60 to 75 percent of installed cost, so $21,000 to $26,000.
- Listing premium effect: 2 to 3 percent on a $1.2M home, so $24,000 to $36,000.
- Holding utility: not zero. The owner uses it 200-plus times before sale.
The Cost vs Value Report would record this as a roughly 70 percent ROI project. The actual financial picture, blending both appraisal and listing premium, lands closer to break-even or modest gain, with five to ten years of personal use effectively free. That’s the framing that makes wellness builds defensible as home improvement rather than discretionary spending. Builders in this category like the Sweat Decks pillar guide on outdoor saunas walk homeowners through this cost-stack math explicitly, which is unusual in the space and worth reading before any decision.

What Doesn’t Pay Back (and Probably Never Will)
Major bathroom remodel. Returned 45 percent in the 2025 report. The home equity loan interest you might use to fund it often exceeds the appraisal lift in present value terms. Think about that: you can lose money twice.
Pool installation. Climate-dependent. In Florida, Texas, and Arizona, pools are close to required. Northern installations are regularly underwater (pun intended) by 30 to 50 percent at resale. Insurance and maintenance costs pile on.
Sunroom addition. Returned 47 percent. They’re an extension of conditioned space that buyers often discount because heating and cooling them is awkward and the rooms feel neither inside nor outside. A screened porch with a ceiling fan does the same job for a quarter of the price.
Whole-home automation. Strange ROI profile. Buyers expect connected thermostats and doorbell cameras as table stakes now. Anything beyond that depreciates fast as protocols change. The Matter standard rolled out in 2023 and hasn’t stabilized installer practices. Investing in smart home tech right now is like buying a Blu-ray collection in 2009. Maybe it holds, probably it doesn’t.
How Appraisers Actually Think (and Why It Matters More Than Zillow)
Back to Mike Torren’s framing, because it’s the most useful thing I’ve heard on the topic.
Appraisers don’t adjust based on what something cost. They adjust based on paired sales. If two homes sold last quarter on the same street, both 2,400 square feet, one with a finished basement and one without, the difference in their sale prices is the appraisal lift for “finished basement” in that submarket. That number is often a quarter of what the basement finish cost the seller.
The implication: ROI on home improvement is not a national average. It’s a hyper-local function of paired sales in your submarket over the prior 12 to 18 months. A wellness build that doesn’t have comparable paired sales nearby will be appraised conservatively even if buyers value it highly.
This is exactly why the Zillow listing premium analysis matters. It captures buyer willingness to pay, which leads the appraisal data by two to three years in fast-changing categories. By the time appraisers have enough comps, the trend is already priced in.
So Where Should Your Money Go?
The improvements that pay back in 2026 are the same boring exterior projects that have paid back for thirty years. Garage doors. Entry doors. Siding. Minor kitchen refresh.
The interesting question is what gets added to that list over the next decade. Outdoor wellness structures are the most plausible candidate based on the listing premium data. Battery storage paired with solar is a second candidate, particularly in California and Texas. Whole-home water filtration is a third in regions with mineral or PFAS concerns.
What doesn’t pay back: anything that signals luxury without function. Buyers have become more cost-conscious about operating expenses since 2022. An improvement that adds $200 to a monthly utility bill is now a deduction from list price, not an addition.
Spend on the exterior. Refresh, don’t rebuild, kitchens and baths. And if you’re in the high-income wellness demographic, the sauna math works better than the standard reports suggest.
Frequently Asked Questions
What home improvement has the highest ROI in 2026? Garage door replacement continues to top the list. The 2025 Cost vs Value Report showed 193.9 percent cost recouped at resale for a midrange steel insulated door, at an average project cost of about $4,500.
Does a kitchen remodel pay for itself? A minor kitchen remodel (refacing, new counters, updated appliances) returned about 96 percent of cost at resale in the 2025 report. A major kitchen remodel returned only 49 percent. Keep the layout, refresh the surfaces.
Do outdoor saunas add home value? Zillow’s 2024 and 2025 Consumer Housing Trends Reports found listings mentioning “sauna” sold for a 2.6 to 3.1 percent premium over comparable listings. The appraisal lift alone is typically 60 to 75 percent of installed cost, but the listing premium effect can push the total financial picture closer to break-even or modest gain.
Are pools worth it for resale? Only in warm climates where they’re expected (Florida, Texas, Arizona). In northern states, pools regularly lose 30 to 50 percent of their installed cost at resale, before accounting for ongoing insurance and maintenance.
How do appraisers determine the value of home improvements? Appraisers use paired sales analysis: they compare recent sale prices of similar homes in the same submarket, one with the improvement and one without. The difference sets the adjustment value, regardless of what the homeowner spent.
Is smart home technology a good investment for resale? Basic connected devices (smart thermostats, video doorbells) are now expected by buyers and cost little to install. Extensive automation systems depreciate quickly as protocols evolve, making them a poor investment strictly for resale purposes.
What home improvements should I avoid before selling? Major bathroom remodels (45 percent return), sunroom additions (47 percent return), and in-ground pools in cold climates consistently underperform. Any improvement that increases monthly operating costs can also suppress your sale price in the current rate environment.
