Engineered hardwood is the better choice for most San Diego homes because it installs over concrete slabs, handles our dry climate with less gapping, and costs 10 to 20 percent less than solid hardwood. Solid hardwood is the better choice if you have a raised wood subfloor, want maximum refinishing potential, and plan to stay in the home for 30 or more years.
The engineered hardwood vs solid hardwood question is one we answer daily. Both are real wood. Both look identical once installed. The difference is in how they are constructed, how they respond to moisture and temperature changes, and how many times you can refinish them. This guide covers everything you need to know to pick the right one for your home, your climate, and your budget. For brand and species details, see our San Diego hardwood flooring service.
- Pick engineered if: slab subfloor, San Diego coastal humidity, radiant heat, basement, budget under $10/sqft
- Pick solid if: raised plywood subfloor, dry inland climate, 30+ year ownership horizon, want 5+ refinishings
- Wear layer: 3-4mm engineered ≈ 5+ refinishings · 2mm engineered ≈ 1-2 · solid ≈ 6-8
- Lifespan: Quality engineered 25-50 yrs · solid 50-100 yrs
- Cost: Engineered $8-$15/sqft installed · solid $9-$14/sqft installed
- San Diego default: Engineered hardwood (slab + coastal humidity)
What Is Solid Hardwood
Solid hardwood is exactly what the name says: a single solid piece of wood milled to a uniform thickness, typically 3/4 inch. Each plank is one species of wood all the way through. Common species include oak, maple, hickory, and walnut.
Solid hardwood is installed by nailing or stapling it to a plywood subfloor. It cannot be glued directly to concrete, and it should not be installed below grade (basements) because it absorbs moisture from concrete and swells. It needs a wood subfloor with a moisture barrier.
The biggest advantage of solid hardwood is refinishing. A 3/4-inch solid plank can be sanded and refinished 5 to 8 times over its life, which means a well-maintained solid hardwood floor can last 50 to 100 years. If longevity is your top priority and you have the right subfloor, solid hardwood is hard to beat.
What Is Engineered Hardwood
Engineered hardwood has a real wood veneer on top, typically 2mm to 4mm thick, bonded to multiple layers of plywood, HDF (high-density fiberboard), or a combination of both. The cross-layered construction is similar to how plywood is made, which gives engineered hardwood superior dimensional stability.
Is engineered wood good? Absolutely. Engineered hardwood looks identical to solid hardwood once installed. The top surface is real wood with real grain. You cannot tell the difference by looking at the floor from above. The difference is underneath, where the layered core resists expansion and contraction far better than a solid piece of wood.
Engineered hardwood can be installed over concrete (glue-down or floating), over radiant heat, and below grade. It can also be nailed to a wood subfloor just like solid hardwood. This versatility is why engineered wood flooring vs hardwood is increasingly a choice that leans toward engineered for the majority of installations we do. Learn more on our hardwood flooring page.
How Engineered Hardwood Is Made
Understanding the construction helps you evaluate quality. Not all engineered hardwood is created equal.
The Wear Layer (Top Veneer)
The wear layer is the real wood surface you see and walk on. Thickness ranges from 0.6mm on cheap products to 6mm on premium ones. The thicker the wear layer, the more times the floor can be refinished.
- 0.6mm to 1mm: Cannot be refinished. Budget product. Avoid if possible.
- 2mm: Can be lightly screened and recoated 1 to 2 times. Decent mid-range.
- 3mm to 4mm: Can be sanded and refinished 2 to 3 times. This is what we recommend.
- 5mm to 6mm: Can be refinished 3 to 4 times. Premium product with near-solid longevity.
The Core Layers
The core is typically 5 to 9 layers of cross-laminated plywood or a combination of plywood and HDF. Higher-quality products use more layers of Baltic birch plywood. Budget products may use poplar plywood or HDF, which is less moisture-resistant. The core determines how stable the floor is and how well it handles moisture.
The Backing Layer
A thin wood or composite layer on the bottom balances the plank and prevents warping. Some products include a pre-attached cork or rubber backing for sound absorption.
Wear Layer Thickness And Refinishing
The wear layer is the real wood veneer on top of an engineered hardwood plank. It is what you see and walk on, and it determines how many times the floor can be sanded and refinished over its lifespan. Solid hardwood does not have a wear layer in the same sense; the entire plank is one piece, so the limit is plank thickness minus tongue-and-groove (typically 5/16 to 3/8 inch sandable depth).
| Plank Type | Wear Layer | Refinishings Possible | Material Cost/sqft |
|---|---|---|---|
| Budget engineered | 1-2 mm | 0-1 | $2.50 - $4.50 |
| Mid engineered | 3 mm | 2-3 | $4.00 - $7.00 |
| Premium engineered | 4-6 mm | 4-6 | $6.00 - $11.00 |
| Solid hardwood (3/4 in) | n/a (sandable depth ~6 mm) | 5-8 | $5.00 - $9.00 |
| Reclaimed solid | n/a | 3-5 | $8.00 - $14.00 |
Skip 1-2mm engineered if you care about long-term value. It cannot be refinished and effectively becomes a permanent floor like LVP. For coastal San Diego homes, a 3-4mm wear layer engineered floor is the sweet spot.

Which Is Better for San Diego Homes
San Diego has some specific conditions that make this decision clearer than in other markets.
Concrete Slab Construction
The majority of San Diego homes, especially those built after 1960, sit on concrete slabs rather than raised wood subfloors. Solid hardwood cannot be nailed or stapled to concrete. You would need to build a plywood subfloor on top of the slab first, which adds $2 to $4 per square foot and raises the floor height.
Engineered hardwood installs directly over concrete using glue-down or floating methods. No additional subfloor needed. This alone makes engineered the default choice for slab homes, which includes most of San Diego's housing stock.
Dry Climate and Low Humidity
San Diego's average relative humidity ranges from 55 to 70 percent near the coast and 30 to 50 percent inland. The dry climate is actually favorable for solid hardwood since the low humidity means less swelling. However, the dryness can cause solid hardwood to shrink and develop gaps between planks, especially in inland areas during Santa Ana wind events when humidity drops below 20 percent.
Engineered hardwood's cross-layered construction handles these humidity swings much better. We see significantly fewer callbacks for gapping and movement with engineered products in San Diego compared to solid.
Sun Exposure
San Diego gets 260 or more sunny days per year. Direct sunlight fades and discolors all wood flooring over time, but both solid and engineered hardwood can be refinished to restore color. UV-protective finishes and window treatments help, but some fading is inevitable in sun-drenched rooms.
Which Is Better for Each Room
Living Room and Dining Room
Both work equally well. If you are on a slab, go engineered. If you have a wood subfloor and want maximum refinishing potential, go solid. Appearance will be identical.
Kitchen
Engineered hardwood is the better choice for kitchens because of its improved moisture resistance. Solid hardwood can work in kitchens if you are diligent about wiping up spills, but the risk of water damage is higher. Neither type should be installed in front of dishwashers without a protective mat.
Bedrooms
Both are equally good in bedrooms. Low moisture, low traffic, and no special requirements. Choose based on your subfloor type and budget.
Bathroom
Neither is recommended for full bathrooms. If you want a wood look in the bathroom, use luxury vinyl plank. Half-baths with no tub or shower are lower risk, and engineered hardwood can work there.
Basement
Engineered hardwood only. Solid hardwood should never go below grade. Even engineered hardwood needs a moisture barrier between the concrete and the flooring.
Species Comparison: Oak, Maple, Hickory, and Walnut
The wood species you choose affects hardness, appearance, and cost. Here is how the most popular species compare in both solid and engineered form:
| Species | Janka Hardness | Character | Engineered Cost/sqft | Solid Cost/sqft |
|---|---|---|---|---|
| White Oak | 1,360 | Moderate grain, versatile, most popular | $5 - $8 | $6 - $10 |
| Red Oak | 1,290 | Prominent grain, warm tones, traditional | $4 - $7 | $5 - $9 |
| Maple | 1,450 | Fine grain, light color, contemporary | $5 - $9 | $6 - $10 |
| Hickory | 1,820 | Heavy grain variation, rustic, very hard | $6 - $10 | $7 - $12 |
| Walnut | 1,010 | Dark, rich color, luxury, softer wood | $8 - $12 | $9 - $14 |
Oak (White and Red)
Oak is the most popular hardwood species in the United States and for good reason. It is hard enough for high-traffic areas, takes stain well, and comes in a wide range of finishes from natural to ebony. White oak is currently more popular than red oak because of its cleaner, more modern grain pattern. White oak is also more naturally water-resistant than red oak.
Maple
Maple has a fine, subtle grain that creates a clean, contemporary look. It is harder than oak and resists dents well. The downside is that maple does not take dark stains evenly because of its tight grain, so it works best in natural or light finishes.
Hickory
Hickory is the hardest domestic wood species commonly used for flooring. It has dramatic color and grain variation that creates a rustic, character-rich floor. Hickory is excellent for homes with dogs because it resists scratches and dents better than any other common species. The heavy grain variation means it also hides wear and imperfections well.
Walnut
Walnut is a luxury species with a rich, dark brown color and flowing grain. It is softer than oak, maple, and hickory, which means it dents more easily. Walnut is best for lower-traffic areas like dining rooms, home offices, and master bedrooms. The natural color is so rich that it rarely needs staining.
Cost Side-By-Side
Cost runs roughly parallel between engineered and solid hardwood for mid-grade material, then diverges at the top of the market.
| Tier | Engineered Installed | Solid Installed |
|---|---|---|
| Budget (oak, basic finish) | $6 - $9/sqft | $7 - $10/sqft |
| Mid (oak/maple, 3-4mm wear) | $9 - $12/sqft | $9 - $12/sqft |
| Premium (white oak wide plank, hickory, walnut) | $12 - $18/sqft | $13 - $20/sqft |
| Refinishing existing | n/a (replace) | $3 - $5/sqft |
Installation Method By Subfloor Type
The biggest practical decision factor between engineered and solid is your subfloor.
- Concrete slab: Engineered hardwood, glue-down or floating with click-lock. Solid hardwood is not a viable option without expensive sleeper systems.
- 3/4 inch plywood subfloor: Both work. Solid is nailed/stapled directly. Engineered can be nailed, glued, or floated.
- Below grade (basement): Engineered only. Solid hardwood swells from concrete moisture below grade.
- Radiant heat: Engineered only. Solid hardwood expands and contracts too much over heat cycles.
- Older crawl-space homes (Coronado Village, Mission Hills, parts of La Jolla): Solid hardwood is viable if the plywood is sound; engineered is also fine.

Frequently Asked Questions
Is engineered hardwood real wood?
Yes. Engineered hardwood has a real wood surface that you see and walk on. The top layer is the same species of wood you would get with solid hardwood. The difference is underneath, where engineered hardwood has a plywood core instead of being one solid piece of wood throughout.
Does engineered hardwood scratch easily?
Engineered hardwood scratches at the same rate as solid hardwood because the surface is the same species of wood with the same finish. Scratch resistance depends on the wood species (hickory resists scratches better than walnut) and the finish (aluminum oxide finishes are harder than polyurethane). The engineered construction underneath does not affect scratch resistance.
Can you refinish engineered hardwood?
Yes, as long as the wear layer (top veneer) is thick enough. Engineered hardwood with a 2mm veneer can be lightly screened and recoated 1 to 2 times. Products with a 3mm to 4mm veneer can be fully sanded and refinished 2 to 3 times. Budget products with a 0.6mm to 1mm veneer cannot be refinished at all.
How long does engineered hardwood last?
Quality engineered hardwood with a 3mm or thicker veneer lasts 25 to 50 years with proper care. Budget products with thin veneers may only last 10 to 15 years because they cannot be refinished when the finish wears through. The core quality also matters since cheap HDF cores can swell if exposed to moisture.
Can you install engineered hardwood over concrete?
Yes. This is one of engineered hardwood's biggest advantages. It can be glued directly to concrete or floated over concrete with an underlayment. A moisture test should be performed on the concrete first, and a moisture barrier is recommended for all concrete installations. Solid hardwood cannot be installed directly over concrete.
Is engineered hardwood waterproof?
No. Engineered hardwood is more moisture-resistant than solid hardwood, but it is not waterproof. Standing water will damage engineered hardwood over time. It handles humidity changes and minor spills well, but it should not be installed in full bathrooms or areas with frequent standing water.
Which adds more value to a home, engineered or solid hardwood?
Buyers generally cannot tell the difference between engineered and solid hardwood. Both add significant value compared to carpet, laminate, or vinyl. The species, color, and condition of the wood matter more for resale value than whether it is engineered or solid. A well-maintained engineered oak floor adds just as much appeal as a solid oak floor.
