Flooring: Comfort, Safety & Creating a Realistic Experience

Here's something that surprises many new simulator owners: the floor matters more than you'd think.

You'll stand on it for every swing. You might practice for hours. The floor affects your comfort, your joints, your stance, and—if you want putting—the roll of your ball.

Most people building simulators treat flooring as an afterthought: "I'll just put the mat on the concrete and call it good." A few months later, their feet hurt, their legs are tired, and putting practice is impossible.

Let's do this right from the start.

Why Flooring Matters

Comfort During Long Sessions

Standing on concrete for two hours is exhausting. Your feet ache, your legs fatigue, your whole body pays a price.

A proper flooring system adds cushioning that lets you practice comfortably for extended periods. The difference between concrete and a foam-backed turf is dramatic—especially as sessions exceed 30-60 minutes.

Joint Protection (Beyond the Mat)

We covered hitting mats in Article 4—protecting your wrists and elbows from impact shock. But your lower body takes a beating too.

Every time your lead foot plants during the downswing, force travels through your knee, hip, and lower back. On unforgiving concrete, that force has nowhere to dissipate. Over thousands of swings, it accumulates.

Cushioned flooring protects your entire kinetic chain, not just your upper body.

Putting Realism

If you want to practice putting in your simulator—and you should—the floor surface determines whether that practice is meaningful.

Random carpet or cheap turf rolls unpredictably. Quality putting turf provides consistent speed and true roll. Some advanced setups even simulate break (slope).

Without proper putting surface, you're not practicing putting—you're just rolling balls at a hole.

Aesthetics and Experience

A bare garage floor with a hitting mat plopped in the middle looks... unfinished. It feels like a compromise, not a destination.

Proper flooring ties the space together. It signals "golf simulator" rather than "golf equipment stored in garage." That psychological difference affects how much you enjoy using it.

Base Layer Options

Whatever surface you put on top, you need to consider what's underneath.

Concrete (Garages, Some Basements)

The challenge: Hard, cold, unforgiving. Transmits shock. Uncomfortable for standing.

Solutions:

• Add foam underlayment before turf
• Use interlocking foam tiles as a base layer
• Consider rubber matting in high-traffic areas

Note: Concrete can have moisture issues. In humid climates or below-grade basements, moisture can seep up, potentially damaging flooring or creating mold issues. Consider a vapor barrier if moisture is a concern.

Plywood/Wood Subfloor (Finished Basements, Rooms)

The situation: More forgiving than concrete but still fairly hard. May have slight flex.

Solutions:

• A thin foam layer plus turf usually provides adequate comfort
• Check for squeaks or weak spots before covering
• Ensure the subfloor is level (shimming may be needed)

Existing Carpet

The challenge: Most carpet isn't suitable for simulator use. Pile height causes uneven lies. Stains easily. Hard to clean.

Options:

• Remove carpet and treat as subfloor
• Cover with protective layer then flooring
• Accept limitations (some golfers leave carpet as-is for the stance area)

If you're serious about the simulator experience, removing carpet from the hitting zone is usually worth it.

Foam Underlayment

A foam layer between your base floor and turf provides cushioning, insulation, and shock absorption.

Interlocking Foam Tiles

What they are: Puzzle-piece foam squares (typically 2'x2') that connect together. Common in home gyms.

Pros:

• Easy to install and remove
• Relatively inexpensive ($1-3 per square foot)
• Good cushioning
• Available in various thicknesses

Cons:

• Can shift over time
• Seams may be visible through thin turf
• Not the firmest base for putting

Best for: General flooring in simulator space, especially stance area.

Foamular/Rigid Foam Insulation

What it is: Rigid polystyrene foam boards (like Foamular 150 or similar). Denser than gym tiles.

Pros:

• Very flat, smooth surface
• Doesn't shift
• Good cushioning
• Can cut to exact sizes

Cons:

• Can dent under repeated pressure (especially under lead foot)
• Requires careful cutting
• Not as resilient as rubber

Best for: Under putting turf where flatness matters.

Important warning: Foam boards compress under your stance during swings. Over time (months of regular use), the foam under your lead foot will show visible dents. This isn't necessarily a problem if it's under hitting mat turf, but it can affect putting surface flatness.

Solution: Don't use compressible foam under the stance area if you're putting there. Use firmer material (rubber, plywood) under where your feet go.

Rubber Underlayment

What it is: Dense rubber sheets or rolls designed for flooring applications.

Pros:

• Excellent durability
• Doesn't compress permanently
• Good shock absorption
• Professional feel

Cons:

• More expensive than foam
• Heavier
• May have slight odor initially

Best for: High-traffic areas, under hitting mats, professional installations.

Turf Selection

Putting Turf

If you want to putt, the turf surface is critical.

Key characteristics:

Stimp rating: A measure of putting green speed. Higher stimp = faster. Most simulator putting greens range from 9-11 stimp, similar to well-maintained public courses. Tour greens can be 12+.

Nap direction: How the fibers lay. Quality putting turf has a consistent nap, affecting roll speed based on direction (with the grain vs. against).

Flatness: Any bumps, seams, or variations affect roll. Good putting turf, properly installed on a flat base, rolls true.

Options:

Basic putting turf: $3-8 per square foot. Provides consistent roll but limited customization.

Premium putting turf: $10-20+ per square foot. Higher quality materials, more realistic roll.

Custom putting greens: Professional installation with built-in breaks, contours, multiple hole positions. $1,000-$5,000+ depending on size and complexity.

For most home simulators, a quality flat putting surface is sufficient. Custom contoured greens are nice but add significant cost.

Fairway/Stance Turf

The area around your hitting mat where you stand.

Key characteristics:

Pile height: Short pile looks like a fairway; longer pile simulates rough. Most stance turf is short pile.

Durability: You'll stand here constantly. It needs to hold up.

Appearance: Should look reasonably realistic and complement your hitting mat.

Options:

Basic landscape turf: $1-4 per square foot. Cheap but may look artificial.

Golf-specific turf: $4-10 per square foot. Designed for simulator use, more realistic appearance.

Professional turf systems: $10+ per square foot. Premium look and feel.

Rough Turf

Some simulators include "rough" turf sections for practicing from different lies.

Reality check: Most hitting mats and launch monitors don't accurately simulate hitting from rough. The ball sits on top of the turf, not nestled down. It's more aesthetic than functional.

If you want rough, it's mainly for appearance or occasional use. Don't prioritize it over good fairway and putting surfaces.

Layout Planning

Your simulator floor has distinct zones with different requirements:

Zone 1: Hitting Area

Where: Centered in front of the screen, where your ball and hitting mat sit.

What goes here: Your hitting mat (covered in Article 4), surrounded by turf or flooring.

Considerations:

• The hitting mat should be at the same height as surrounding turf (or very close)
• Some mats have optional stance extensions
• Ensure the mat is stable and doesn't shift during swings

Zone 2: Stance Area

Where: Where your feet are during your swing—around and behind the hitting mat.

What goes here: Comfortable, stable turf on cushioned base.

Considerations:

• Needs cushioning for comfort during long sessions
• Must be firm enough for stable footing
• Height should match hitting mat
• Consider both right-handed and left-handed stance positions

Zone 3: Putting Area

Where: The area from hitting position toward (and around) the screen.

What goes here: Quality putting turf on very flat, stable base.

Considerations:

• Flatness is critical—any bumps ruin putting practice
• Turf should extend far enough for various putt lengths
• Cup location(s) if you want actual hole practice
• Some golfers run putting turf up to the screen; others stop it before the hitting zone

Zone 4: Surrounding Floor

Where: The rest of the simulator space—walkways, equipment areas, spectator zones.

What goes here: Whatever works—turf, carpet, bare floor.

Considerations:

• Traffic paths need durability
• Equipment areas need stability
• Doesn't have to match the main turf (but looks better if cohesive)

Height Transitions

One of the trickier aspects of simulator flooring: everything needs to be at a similar height, or you create awkward transitions and unrealistic ball lies.

The challenge:

• Your hitting mat is X inches thick
• Your foam underlayment is Y inches thick
• Your turf is Z inches thick
• These all need to work together

Solutions:

Build up to match: If your hitting mat is 1.5" thick and your foam + turf is only 1", add more foam (or plywood) under the turf to match.

Route the mat into the floor: Some installers cut out a section of foam where the hitting mat sits, recessing it to match surrounding turf height.

Use matched systems: Some companies (Fiberbuilt, Carl's, etc.) sell mat + turf combos designed to be the same height.

Accept minor differences: Small height variations (under 0.5") are generally fine and don't significantly affect ball lie or swing feel.

Installation Approaches

Approach 1: Loose Lay

What it is: Lay foam tiles, then roll out turf on top. Nothing permanently attached.

Pros:

• Easy to install
• Easy to remove/change
• Minimal commitment

Cons:

• Can shift over time
• Seams may separate
• Less professional result

Best for: Renters, temporary setups, those who might reconfigure.

Approach 2: Adhered Installation

What it is: Glue foam to floor, tape seams, adhere turf to foam.

Pros:

• Stable, professional result
• No shifting or separation
• Cleaner seams

Cons:

• More difficult to remove
• Requires more time and materials
• Permanent (or semi-permanent)

Best for: Dedicated simulator spaces, those wanting the best result.

Approach 3: Frame-Contained

What it is: Build a wooden frame around the floor area, then fill with foam and turf. The frame contains everything.

Pros:

• Clean edges
• Easy to define zones
• Can create elevation changes intentionally

Cons:

• More construction work
• Creates a "step up" into the hitting area
• Wood visible around edges

Best for: Custom installations, those wanting distinct zones.

Budget Considerations

Flooring costs can range from minimal to substantial:

Budget approach ($200-$400):

• Interlocking foam tiles for cushioning
• Basic turf from Amazon or hardware store
• Hitting mat area only, surrounding floor left bare

Mid-range approach ($500-$1,000):

• Quality foam underlayment
• Golf-specific turf for stance and putting
• Coverage of main simulator area

Premium approach ($1,500-$3,000+):

• Premium putting turf
• Professional-grade stance turf
• Full coverage including walkways
• Potentially custom contoured putting green

The floor doesn't have to be expensive to be functional. But premium flooring dramatically improves the experience and aesthetics.

Common Flooring Mistakes

Mistake 1: No Underlayment on Concrete

"I'll just lay turf directly on the concrete."

You'll feel every minute of practice in your feet, knees, and back. Spend the $100-$200 on foam tiles.

Mistake 2: Foam Under Putting Surface

Compressible foam under putting turf creates inconsistencies over time. Use rigid materials (dense foam board, plywood, or rubber) under putting areas.

Mistake 3: Ignoring Height Differences

A hitting mat that sits 1" higher than surrounding turf creates an unnatural ball lie and looks sloppy. Plan heights in advance.

Mistake 4: Cheap Putting Turf

That $2/sqft turf from the home improvement store might look okay, but it doesn't roll true. Putting practice on bad turf builds bad habits.

Mistake 5: Covering the Entire Space First Day

Lay out your hitting mat and key equipment first. Hit some balls. See where you want to stand, where balls land, where you walk. Then finalize flooring layout.

My Recommendations

For most simulators:

• Base: Interlocking foam gym tiles (stance area), rigid foam board (putting area)
• Stance turf: Golf-specific turf, $5-8/sqft range
• Putting turf: Quality putting green turf, $10-15/sqft range
• Coverage: Main hitting/putting area plus 1-2 feet buffer

Budget approximately $600-$1,200 for a complete, quality floor.

This gives you comfort for long practice sessions, true putting roll, a professional appearance, and durability for years of use.

If budget is tight: Prioritize the hitting/stance area first. You can add putting turf later as an upgrade.

If you want the best: Consult with a professional simulator installer about custom flooring options, potentially including contoured putting greens.
