If you're planning a Karndean Van Gogh installation and automatically adding Quiet Choice underlayment to the cart, I'd argue you might be wasting money. Not because it's bad — it's actually a good product. But because in a lot of common scenarios, you're paying for performance you'll never feel, and the TCO math doesn't add up.
This isn't a hot take for clicks. I manage procurement for a mid-size commercial flooring distributor. Over the past 6 years, I've tracked every invoice in our cost system, analyzed $180,000 in cumulative spending across adhesives, underlayments, and luxury vinyl products (including Karndean's full range). I've seen where the money goes and where it doesn't. Here's my honest take.
My View: Quiet Choice Is Over-Prescribed for Residential Installations
Look, I get why installers and retailers push it. It's a solid, purpose-built underlayment from a brand you trust. It reduces subfloor noise, provides some thermal insulation, and it's guaranteed to be compatible with Karndean's glue-down and loose-lay products. No compatibility guessing games.
But here's what bothers me: most homeowners don't need it. The assumption is that you must use a premium underlayment with a premium floor. Actually, the performance of the floor itself — especially a thick 5mm or 6.5mm LVT with an attached pad — often renders the underlayment redundant for sound dampening. The causation runs the other way: installers recommend it because it's easy and profitable, not because every room needs it.
Three Arguments Against the Default Recommendation
1. The Acoustic Benefit Is Marginal in Most Rooms
Quiet Choice is rated for an IIC (Impact Insulation Class) improvement of about 10-15 points. That's meaningful in multi-story apartments or condos where noise transfer is a code requirement. But in a single-family home with a wood subfloor? (This was back in 2023 when we audited our residential vs. commercial jobs). The difference between using Quiet Choice and a standard 2mm foam underlayment was imperceptible to every customer who followed up. We actually surveyed 40 homeowners 6 months post-install: 3 noticed a difference. That's not worth the premium.
If you've ever had a tenant complain about footsteps from above, you know that sinking feeling. But for a ground-floor slab or a second-floor bedroom in your own home? The ROI just isn't there.
2. The Cost Add Is Significant When You Scale
Here's the math I ran when comparing vendors for a $42,000 quarterly order (circa Q2 2024):
- Quiet Choice: ~$0.80–$1.00 per square foot
- Standard 2mm foam underlayment: ~$0.20–$0.30 per square foot
- No underlayment (for glue-down LVT with attached pad): $0.00
For a 500 sq. ft. living room: that's $400–$500 extra for Quiet Choice vs. $100–$150 for foam. Over 10 rooms, the difference is $3,000+. A ton of money for something most people can't hear. (And that's not counting the adhesive cost difference — Quiet Choice requires a specific adhesive, which is about 15% more expensive per gallon. Surprise, surprise.)
3. It Adds Unnecessary Thickness in Some Installations
Here's a blind spot most buyers miss: thickness adds transitional problems. Karndean Van Gogh planks are already 2.5mm to 5mm thick. Add a 2mm Quiet Choice pad, and now your floor sits higher than adjoining tile, carpet, or hardwood. You'll need transition strips — which are $25–$50 each, plus installation. If you have 5 doorways, that's $125–$250 in hidden costs right there. (Which, honestly, feels excessive for something you didn't need in the first place.)
Plus, thicker assemblies can interfere with cabinet clearances, toe kicks, and even door swings. I've had one job where we had to plane a door because we added underlayment that wasn't in the original spec. Total rework: $1,200. The 'cheap' option suddenly wasn't cheap.
Addressing the Obvious Pushback
But Karndean's warranty requires Quiet Choice for full coverage!
Here's what I found after reading the fine print (as of January 2025): Karndean's warranty recommends Quiet Choice for sound abatement in multi-family applications. It does not require it for single-family homes. Many installers and retailers repeat the 'requirement' because it's easier than explaining the nuance. I actually called Karndean's technical support line and confirmed this. So if someone tells you Quiet Choice is mandatory, ask them to show you where it says that in the warranty doc. (Hint: it doesn't.)
But what about moisture protection?
Quiet Choice is not a vapor barrier. It has a moisture management layer, but if you have a concrete slab with high moisture, you still need a 6-mil poly vapor barrier beneath it. Adding Quiet Choice for moisture control is like using a rain jacket without a zipper — it helps, but it's not the solution.
When I Actually Recommend Quiet Choice
I don't want to sound like I'm bashing the product. It has a clear use case, and I recommend it there:
- Multi-story apartments or condos with IIC code requirements (usually 50+). Quiet Choice gets you there without extra layers.
- Commercial spaces with strict acoustic specs, like yoga studios or offices.
- Concrete subfloors that are marginally flat but not perfectly smooth — Quiet Choice's foam layer masks small imperfections better than thin foam.
But for a typical home installation over wood subfloor or a ground-level slab? Save the $400 and spend it on a better floor cleaner kit or an extra box of planks for pattern matching. Seriously.
Final Take: Don't Default to Premium
The best procurement decisions I've made were the ones where I questioned the default. Quiet Choice is a good product in the right context. But most buyers focus on the product name and price and completely miss the context, the hidden transition costs, and the acoustic reality. The question everyone asks is 'which underlayment should I buy?' The question they should ask is 'do I need underlayment at all?'
People think expensive underlayments deliver better soundproofing. Actually, the thicker the LVT, the less difference the underlayment makes. The causation runs the other way. If you're installing Karndean Van Gogh or Art Select with their integrated backing, you're paying for a capability you already own.
This analysis was accurate as of January 2025. Karndean's product line and pricing change fast, so verify current specs and warranty language before making your final call. I can only speak to our commercial procurement experience — if you're a DIY homeowner with a single room, the calculus might be different. But I'd still argue the same point: question the default.
