Shallow Putting Cups for Indoor Greens & Golf Simulators

Shallow putting cups turn a strip of turf into a real target when you're working on your speed control or setting up a full nine-hole layout in the garage. 

At OSSS, all putting cups use a USGA-regulation 4.25-inch diameter, so the main buying decision is cup depth and bottom style. Shallow and super-shallow options accommodate different turf thicknesses, while real-bottom and open-bottom cups suit carpeted floors or thin-backing surfaces. The cups install directly into a cutout in the turf, so there’s no need to drill into the floor.

These indoor putting cups for artificial turf pair naturally with a flagstick for a regulation-style look, and the bright white color enhances the appearance further. If you’re building a simulator room for practice or entertaining, pair your cups with our indoor putting green turf for a finished setup.

How to Choose Putting Green Cups for Your Setup

Putting cups for artificial turf are available in different designs and depths. Every OSSS cup uses the same 4.25-inch regulation opening, so select the style that best matches your turf thickness and subfloor.

Real Bottom vs Open Bottom: Which Style Do You Need?

Real-bottom cups have a solid base, allowing the ball to audibly hit the bottom when you make a putt. That feedback makes them the most realistic option for indoor simulator greens and artificial turf mats, including Money Putt, True Turf, and One Putt.

Open-bottom cups allow the ball to settle below the green surface, making them better suited to carpeted floors or thinner backing surfaces. These cups ship with a built-in white fabric insert, so your subfloor won't show through the opening.

Shallow vs Super Shallow Putting Cups: Matching Depth to Turf Thickness

Shallow real-bottom cups run from 1.125" to 3-13/16" and work with most standard putting turf configurations, including Money Putt, True Turf, and One Putt. Its rim sits slightly below the turf surface to create the appearance and feel of an in-ground golf hole. 

Featuring a 7/8" to 1.25" depth, super-shallow real-bottom cups are intended for very low-pile turf or a setup where foam underlayment has raised the floor level enough that a standard shallow cup leaves a visible gap around the rim.

Not sure which to pick? Start with shallow cups. It's the right call for most home and simulator setups. OSSS custom-made shallow cups have a 7-10 day lead time, while super-shallow real-bottom cups ship in 1-2 business days. If you're on a deadline, that difference matters.

Installing Golf Cups for Putting Green: No Drilling Required

An indoor putting cup does not require core drilling into your floor. To install one, cut a 4.25" opening in the turf using a cup cutter or hole saw, drop the cup in, and the turf tension will keep it in place.

Real-bottom cups are self-supporting once installed in the turf. On very soft surfaces, an open-bottom cup may benefit from a thin foam layer beneath it for added support. These golf cups for putting green setups hold a USGA-regulation 4.25" diameter, the same size as a standard golf hole on any course.

Putting Green Cups and Flags: Completing Your Indoor Setup

A putting cup gives you a clear target, but adding the OSSS golf flagstick creates a regulation-style indoor green. With this precise putting cups and flags combination, golfers get a real reference point for distance and alignment on every practice putt.

The flagstick's magnetic base is designed specifically for our shallow and super-shallow putting cups. It comes in multiple colors, including red, royal, and black, to match your room aesthetics.

Putting cups and flags are usually bought together, but the flagstick has a 3-week lead time, so order it early when finishing a room on a schedule. Browse all golf simulator accessories to round out the setup.

Indoor Putting Cup FAQs

What depth putting cup do I need for my indoor green?

It depends on turf pile height and underlayment. Standard shallow putting cups work with most indoor greens running Money Putt, True Turf, or One Putt. If your turf has very low-pile or sits on foam underlayment, go super-shallow for a flush fit. 

What is the difference between shallow and super-shallow putting cups?

The difference between shallow putting cups and super-shallow cups is depth. Shallow cups sit slightly deeper, giving a more realistic in-ground feel on standard turf. Super-shallow cups sit nearly flush, built for very low-pile turf or a raised subfloor. 

What is the diameter of a golf hole cup?

Every OSSS putting cup has a USGA-regulated diameter of 4.25 inches, the same size as a standard golf hole on any regulation course for realistic practice results.

Do I need to drill into my floor to install a putting green cup? 

No. An indoor putting cup installs directly into a cutout in the turf, so you don't have to core drill into the floor. Simply cut a 4.25-inch opening with a cup cutter or hole saw, then place the cup into the opening. Turf tension holds the cup in place, while real-bottom cups provide their own solid base. 

Does a putting green cup work with a flagstick?

Yes. OSSS offers golf flagsticks featuring a magnetic base that works with its shallow and super-shallow cup styles to add a clear visual target and give an indoor green a more traditional golf-hole appearance for practice sessions. The magnetic base sits securely on the cup rim without hardware, drilling, or adhesive, so you can easily remove it between shots.
