LVP vs engineered hardwood: how the two floors really compare
One is a waterproof plastic plank, the other a thin layer of real wood on a stable core. Which one fits depends on water, the slab, and how long you plan to keep the floor.
Choose LVP where water and a damp concrete slab are the main worries, and engineered hardwood where you want real wood that can be sanded and refinished later. Vinyl makers call their rigid plank waterproof and say never to sand it. Engineered wood can also go over a slab, but it asks for drier concrete (75 percent relative humidity in Shaw's guide, against 85 to 90 for vinyl) and a home kept at roughly 35 to 55 percent humidity.
Both are sold as wood-look floors for the same rooms, so the differences hide in the installation guides and the warranties. The scorecard below takes each property in turn, with the guide that says so, and then turns it into advice room by room.
The scorecard
| Property | LVP (rigid vinyl plank) | Engineered hardwood |
|---|---|---|
| Water on the surface | Mannington: "ADURA Max is a completely waterproof product." Shaw's warranty covers topical moisture as long as water does not run over the edge of the floor. | Hallmark: "Since wood flooring is not compatible with wet conditions, Hallmark Floors does not warrant against moisture related issues or related damage under warranty." |
| Over a concrete slab | Floats over concrete within 85 to 90 percent relative humidity, by brand. | Shaw: "Engineered hardwood flooring can be installed on, above, or below-grade." Concrete at 75 percent RH or less, or a vapor retarder. |
| Calcium chloride limit | 8 lbs in the Shaw, COREtec and Mannington guides. | Shaw: "should not be greater than 3 pounds per 1000 square feet of area. If it exceeds these limits, DO NOT install the flooring." |
| Sanding and refinishing | Mannington: "Never wax, polish, sand or lacquer a Mannington ADURA Floor." | Possible when the wear layer is thick enough. NWFA guidance: below 2.5 mm (3/32 inch), "the floor should not be sanded." |
| Indoor humidity | The three vinyl guides compared give an installation temperature range (Shaw: 55 to 85 degrees F) and no indoor humidity band. | Shaw: 35 to 55 percent before delivery, during and after installation. Mannington: 35 to 50 percent. |
| Gap at the walls | 1/4 inch in most rooms (Shaw, Mannington). | Shaw, floating: "1/2" of expansion space required at all vertical surfaces." |
| Under cabinets and islands | Brand by brand: Shaw allows it over a glued-down area, Mannington does not. | Hallmark, floating: "Cabinets and built in appliances should never be installed on top of the floating wood floor." Shaw: cabinets go in before the floor. |
| Stairs | Shaw: "Shaw requires fully adhering installations on steps for safety and structural stability reasons." | Shaw stair nosing: "Secure by gluing and nailing/ screwing down into place." |
Two rows decide most choices: water and refinishing. The rest are installation details a good installer handles either way, as long as the product's own guide is followed.
Room by room
- Kitchen. Spills and a dishwasher favor vinyl. Whichever you pick, the floor's guide decides whether the cabinets go in first or the floor does.
- Bathrooms. Vinyl, for the water row alone: wood flooring makers do not warrant against moisture. Even vinyl warranties exclude flooding and standing water from leaks.
- Ground floor on a slab. Either can work. Test the concrete first, because the limits differ: about 75 percent RH for engineered wood in Shaw's guide, 85 to 90 percent for rigid vinyl.
- Bedrooms and living rooms. Either. Engineered wood earns its price here if you want a floor you can sand and refinish in later years.
- Stairs. Both are glued on steps; the difference is the nosing and the look, which our guide to carpet to wood treads covers in detail.
Refinishing: the long game
Engineered hardwood is a real wood surface, its wear layer, glued over a stable core. How thick that layer is decides whether the floor can ever be sanded. NWFA's magazine puts the range plainly: "Engineered wood floors can have wear layers ranging from 1/16" to 1/4"."
- NWFA's minimum wear layers for its refinishable program: "Unfinished Smooth Wood Flooring: 3.2 mm (4/32")" and "Factory Finished Smooth Wood Flooring: 2.5 mm (3/32")".
- Below that line, NWFA guidance says the floor "should not be sanded."
- Each sanding costs material: "A traditional sand job will remove 1/32" to 1/16" of actual material from the surface of the floor."
So ask for the wear layer in millimeters before you buy. A thin one is a wood floor that, like vinyl, will be replaced rather than refinished.
A San Diego note: permits
Inside the City of San Diego, laying a new floor does not need a building permit. The Municipal Code lists "Installation of floor covering" among repairs exempt "without limit to valuation". The same section adds that its exemptions "are not exemptions from the electrical, plumbing, and mechanical permit requirements," so moving an outlet or a toilet during the job is a separate question.
Outside the city limits, the County of San Diego or the city you live in sets its own rules, so check with that building department.
Quick answers
Is LVP better than engineered hardwood?
Neither is better everywhere. Rigid vinyl plank handles water and damper slabs better and cannot be sanded; engineered hardwood is real wood that can be refinished if its wear layer is thick enough, but its makers do not warrant it against moisture.
Can engineered hardwood go over a concrete slab?
Yes. Shaw's guide says engineered hardwood can be installed on, above or below grade, with the concrete at 75 percent relative humidity or less (above that, a vapor retarder) and no more than 3 lbs by the calcium chloride test. NWFA recommends only engineered, not solid, wood over below-grade concrete.
Can engineered hardwood be refinished?
If the wear layer is thick enough. NWFA guidance says a floor with less than 2.5 mm (3/32 inch) of wear layer should not be sanded, and each sanding removes 1/32 to 1/16 inch.
Can LVP be sanded or refinished?
No. Mannington, for example, says never to wax, polish, sand or lacquer its ADURA vinyl floors. A worn vinyl plank is replaced, not refinished.
What humidity should a home with engineered hardwood keep?
Shaw asks for 35 to 55 percent relative humidity before delivery, during and after installation, with the HVAC running; Mannington asks for 35 to 50 percent. Follow the range in your product's guide.
Do I need a permit to replace flooring in San Diego?
Not a building permit inside the City of San Diego: its Municipal Code exempts the installation of floor covering without limit to valuation. Electrical, plumbing and mechanical permits are separate, and other cities and the County set their own rules.
