Laminate Flooring in Missouri: Costs, AC Ratings and Limits
Laminate shares vinyl plank's biggest advantage on Missouri ground — it floats — and has a weakness vinyl does not: the core is wood, and wood and water do not negotiate.
What it costs
Installed laminate runs about $3 to $9 per square foot in Missouri, which puts it between carpet and vinyl plank for most rooms.

It floats, which is the good news
Like vinyl plank, laminate is laid as a floating raft over an underlay rather than bonded to the substrate. Small seasonal substrate movement passes underneath it instead of into it, which is exactly what you want on ground that is still settling. It needs the same flatness discipline — about 3/16 in over 10 ft — and the same expansion gap at the perimeter.
The core is the bad news
Laminate’s core is high-density fiberboard. Water that reaches it through the joints swells it, and swelling is not reversible — the edges lift and stay lifted. Water-resistant laminates improve the seams and the surface; they do not change what the core is made of. That rules it out of bathrooms, laundries and anywhere a slow leak is plausible, and makes it a reasonable choice in bedrooms, hallways and living rooms.
The AC rating
AC ratings run from AC1 to AC5 and describe abrasion resistance. AC3 is the sensible domestic minimum; AC4 suits a busy hallway or a house with dogs. It is printed on the box and it is a better predictor of how the floor will look in five years than the thickness is.
Underlayment is not optional
The underlay does three jobs: it evens out minor substrate variation, it deadens the hollow sound a floating floor otherwise makes, and over concrete it carries the vapor barrier. Skipping it is the most common reason a laminate floor sounds cheap underfoot.
Common questions
Laminate or vinyl plank?
Where water is plausible, vinyl plank. Where it is not, laminate is often harder-wearing at the same money and reads warmer underfoot. Both float, so both suit moving ground.
Can it go on stairs?
Only with matching stair-nose profiles from the same range, and it is hard and slick underfoot in socks. Carpet or wood treads are the better answer on stairs.
Does it need an expansion gap?
Yes, at every wall and every fixed object. A floating floor that cannot move peaks in the middle of the room.
