How To Choose The Best Gas Cooktop

Picking the right gas cooktop depends on three things: how much heat you need, the space you have in your countertop, and how much cleaning you are willing to do. Get those three right and the rest falls into place.

Burner count and BTU output

BTU (British Thermal Unit) measures how much heat a burner produces — a 20,000 BTU burner boils a large pot of water fast but needs careful attention for a low simmer. Most 30-inch cooktops pack four or five burners, while 36-inch models often squeeze in five or six. A dedicated high-BTU wok burner (12,000 BTU or higher) is worth it if you stir-fry regularly, and a low-BTU simmer burner (around 3,000 to 4,000 BTU) saves sauces from scorching.

Cutout dimensions and installation

Your countertop cutout decides which cooktops fit without expensive cabinet work. Measure the width and depth of your existing hole — a 30-inch cooktop typically needs a cutout around 28.5 by 19 inches, while a 36-inch unit needs roughly 34 by 19 inches. Many buyers report needing to widen the cutout by a fraction of an inch, especially in older homes, so always check the manufacturer’s cutout template before ordering.

Fuel type and conversion

Most gas cooktops ship set for natural gas (NG) but include a conversion kit for liquid propane (LPG). If you live in a house without a gas line or use a propane tank, confirm the kit comes in the box — and note that some regulators included are for NG use only, requiring a separate propane regulator.

In‑Depth Reviews

★ Best Overall

1. Frigidaire Gallery 36 Inch Stainless Steel Gas Cooktop, 5-Burner Range with Liquid Propane Cooktop Conversion Kit, FGGC3645QS

Our pick — over 4.5★ from 350+ verified ratings; the strongest balance of quality and price.

Express-Select Controls5 Burners

The trusted workhorse that balances power and everyday usability without the sticker shock.

This Frigidaire Gallery cooktop gives you a 36-inch cooking surface with 5 sealed burners, including a front right burner rated at 12,000 BTU for searing and a rear right 5,000 BTU for gentle simmering. The angled front controls sit on a slanted edge, which owners mention stays away from oil splashes and heat from the burners — a thoughtful detail that keeps the knobs cooler during long cooking sessions.

The Express-Select controls let you go from warm to boil with a single turn, and the included propane conversion kit means you can use it with liquid propane from the start. Customers note that installation required widening the cutout by 1/8 inch in an older house, so measure your space carefully. At 50 pounds it is lighter than many older cooktops, making the install easier on your back.

Reviewers praise the beefy cast iron grates and the solid all-metal build, though one reviewer noted that the stainless steel deck feels a bit cheap despite the grates being heavy-duty. The continuous spark ignition fires every time, and the simmer performance earns consistent compliments for its control range.

Built to Last

  • Express-Select controls for precise temperature changes from warm to boil
  • Includes liquid propane conversion kit with regulator and propane jets
  • Angled front controls reduce heat exposure to knobs

Consider This

  • Stainless steel deck feels less premium than the cast iron grates
  • Liquid under knobs can be a nightmare to clean if spills happen

The reliable choice: If you want a well-known brand with easy propane conversion and a layout that covers all pan sizes, this is the cooktop to beat for most families.

One real limit: The 12,000 BTU max burner is solid but falls short of the 20,000 BTU units found on competing models for serious wok cooking.

Best Value

2. TOPWISH 30 Inch Gas Cooktop, Gas Stove Top Propane 5 ITALY SABAF Burner, 41400 BTU

SABAF BurnersNG/LPG Convertible

Five Italian SABAF burners at a price that undercuts the competition by a wide margin.

This 30-inch cooktop packs five sealed burners made by SABAF in Italy, including a 12,000 BTU triple-ring wok burner that delivers concentrated heat for stir-frying. The total output of 41,400 BTU across all burners means you can boil pasta on one while simmering sauce on another without waiting. It ships set for natural gas and includes conversion nozzles for propane — one buyer mentioned you need to buy an adapter from a propane shop if you plan to hook it to a tank.

The heavy-duty 304 food-grade stainless steel surface and sturdy cast iron grates are easy to clean, and the flame failure detection system (a thermocouple that cuts gas if the flame goes out) adds a safety layer. Reviewers point out that everyone who sees it likes it, and the absence of plastic knobs is a noted plus. One reviewer pointed out the middle burner sits slightly lower than the others, but that did not affect performance.

The fit and finish feel higher than the price suggests, though you may find the included instructions a bit sparse. At 4.25 inches tall, it fits into standard cutouts without raising the countertop height.

Why It Stands Out

  • Five Italian SABAF sealed burners with a powerful 12,000 BTU triple-ring wok burner
  • NG/LPG convertible with all nozzles included
  • Heavy-duty 304 food-grade stainless steel for easy cleaning

The Trade-Off

  • Middle burner sits lower than the others — cosmetic, not functional
  • Propane tank setup may need a separate adapter from a local shop

Best for budget-conscious cooks: If you want Italian burner quality without spending premium money, this cooktop delivers real performance where it matters — at the flame.

Who might pass: Anyone who wants a brand name with a long service network; the TOPWISH support is less established than major appliance brands.

Best Griddle Combo

3. 30 Inch Built-In Gas Cooktop with Griddle, 5 Italy SABAF Powerful Burners Over 92% High Efficiency, Max 48300BTU

20,000 BTU BurnerReversible Griddle

A 20,000 BTU center burner plus a reversible griddle that turns your cooktop into a flat-top grill.

This 30-inch unit from Amzgachfktch delivers a total of 48,300 BTU across five SABAF burners, with a 20,000 BTU tri-ring center burner that handles boiling and searing with authority. It also includes a reversible griddle — smooth side for eggs and pancakes, ridged side for steaks and burgers — giving you a breakfast station and grill without buying extra cookware. The griddle is made from heavy-duty cast iron with a comfortable wide handle for easy gripping.

It is CSA certified for US and Canada, and the flame failure detection shuts off gas automatically if the flame goes out. Shoppers say that the first unit arrived damaged (a burner would not stay on), but the replacement worked perfectly and fit the cutout with no adjustments. One owner reported that the gas flow control is not very sensitive, with the knobs moving freely through the first three-quarters of the turn before actually changing the flame intensity.

The 304 stainless steel panel resists stains, and the sealed burners prevent food from falling inside. At 4.5 inches tall, it matches the profile of most standard cooktops. The automatic electric pulse ignition runs on a 120V AC cord that comes with a 3.6-foot plug.

Griddle Advantage

  • 20,000 BTU tri-ring center burner for extreme heat
  • Reversible cast iron griddle/grill included
  • CSA certified with flame failure protection

Watch For

  • Knob control lacks sensitivity — most of the turn has no effect until the last quarter
  • Quality control inconsistency reported with first unit defects

Pick this for versatility: If you want a cooktop that does double duty as a griddle for breakfast and a high-heat burner for dinner, this model gives you both without taking extra counter space.

Be aware: The imprecise flame control means delicate simmering requires more attention than with more expensive models.

Best 36-Inch Value

4. 36 Inch Built-in Gas Cooktop 5 Italy SABAF Sealed Burners 40400 BTU Stainless Steel NG/LPG Convertible

15,000 BTU BurnerAluminum Knobs

A 36-inch SABAF burner layout at a price that undercuts most 30-inch competitors.

Weceleh brings a 36-inch wide gas cooktop with five Italian SABAF burners that deliver a total of 40,400 BTU. You get a 15,000 BTU burner for high-heat boiling and searing, a 10,000 BTU burner for frying, two 6,000 BTU burners for everyday sautéing, and a 3,400 BTU simmer burner that keeps sauces warm without burning. The heat-resistant aluminum alloy knobs offer a durable, tactile feel that resists melting or cracking over time.

At only 3.34 inches tall, it sits lower than many other 36-inch models, which helps if you have a shallow countertop depth. Buyers on a vintage Catalina yacht installed this cooktop and loved the upgrade, noting it fit easily into their existing cutout. Another buyer mentioned that the knobs are a bit hard to turn initially and that the flames take a moment to flare up after the pilot-like spark ignites.

The 2-year warranty provides longer coverage than most budget-friendly options, and the included LPG nozzle kit and pressure regulator make propane conversion straightforward. One customer observed that the flame adjustment only works in the final 1/8 of the knob rotation, meaning the low setting runs higher than ideal for extremely delicate cooking.

Why Size Matters

  • 36-inch width gives you room for multiple large pots and sheet pans
  • Aluminum alloy knobs resist heat better than plastic alternatives
  • 2-year warranty exceeds standard coverage for this price tier

What Holds It Back

  • Flame adjustment range is narrow — most response happens at the end of the knob turn
  • Knobs require more force to turn than typical gas cooktops

Grab it for big kitchens on a budget: If you need a full 36-inch cooking surface but cannot justify the premium price of high-end Italian brands, this Weceleh delivers SABAF quality at a fraction of the cost.

skip it if: You need precise low-flame control for professional-level simmering — the narrow knob range makes delicate heat management frustrating.

Compact Pick

5. GASLAND 24 Inch Gas Cooktop with Griddle 4 Burners, GH60EF Drop-in Propane Stove Top

22,300 BTU TotalReversible Griddle

A 24-inch powerhouse that squeezes a griddle and four burners into a footprint made for small spaces.

GASLAND designed this 24-inch drop-in cooktop for kitchens where every inch counts — RVs, outdoor cooking stations, and compact apartment counters. It has four sealed burners delivering 22,300 BTU total, including a 9,500 BTU triple-ring wok burner that handles high-heat stir-frying. The included 2-in-1 reversible griddle (16.7 by 9.7 inches) offers a flat side for pancakes and eggs and a ridged side for steaks and veggies, turning a small cooking area into a versatile station.

The black enamel finish with heavy cast iron pan support grates cleans easily with a damp cloth, and the melt-proof zinc alloy knobs stay cool during use. It runs on 120V AC power for automatic pulse ignition (with a 4.59-foot cord), and the thermocouple flame-out failure device cuts gas if the flame goes out accidentally. One buyer installed it in an outdoor kitchen and praised its constant power and fantastic performance.

At 21.6 pounds, it is one of the lightest cooktops in this lineup, making installation a solo job. It supports both natural gas and propane with the included conversion kit, and the ETL certification confirms it meets US and Canada safety standards.

Small Kitchen Hero

  • 24-inch width fits tight spaces without sacrificing a griddle
  • 9,500 BTU triple-ring wok burner for high heat in a compact layout
  • Weighs only 21.6 pounds for easy drop-in installation

Consider Before Buying

  • Total BTU output of 22,300 is lower than full-size models
  • Four burners limit multi-pot cooking for large families

Ideal for small spaces: If you are outfitting an RV, outdoor kitchen, or apartment with limited counter space, this 24-inch gas cooktop gives you serious cooking versatility without dominating the room.

Not the right fit: If you regularly cook for more than four people, you will want the extra burner and higher total BTU of a 30-inch or 36-inch model.

Slim Profile

6. ThermoMate Heavy 30 Inch Gas Cooktop with 5 Italy Sabaf Power Burners, 304 Stainless Steel

1.67″ ThinCSA Certified

A 1.67-inch height makes this ThermoMate the thinnest drop-in gas cooktop you can install without cutting cabinet supports.

ThermoMate’s 30-inch gas cooktop stands out for its ultra-slim 1.67-inch profile, which allows it to drop into shallow countertops where standard 4-inch cooktops require shaving wooden supports underneath. It uses five Italian SABAF burners: a 13,000 BTU wok burner, a 10,300 BTU rapid burner, two 7,000 BTU semi-rapid burners, and a 4,000 BTU auxiliary burner. Buyers report the burners work perfectly from the start without fading when turned down to low, and the flame stays even and hot.

The integrally molded 0.03-inch 304 stainless steel panel resists stains and discoloration, and the removable cast iron grates are dishwasher-safe for easy cleanup. A push-type rotary switch controls ignition, adding a child-safety measure by requiring a deliberate push before the knob turns. One reviewer praised it as the best bang for the money.

It is CSA certified and includes a thermocouple flameout protection system that shuts the gas off when no flame is detected. The cooktop came with only 2 clamps for a 4-hole design, but the reviewer reused clamps from their old unit. The gas pressure regulator included is for NG use only, so propane conversion requires a separate regulator.

Why It Fits

  • Ultra-slim 1.67-inch height installs without modifying cabinet supports
  • Dishwasher-safe cast iron grates simplify cleanup
  • Push-to-turn ignition helps prevent accidental burner activation

Heads Up

  • Regulator included is for NG only — propane conversion needs a separate regulator
  • Only 2 mounting clamps included for 4 clamp positions

Best for tight countertops: If your existing cutout is shallow and you want to avoid cutting cabinet supports, this thin-profile cooktop slides right in without structural changes.

Think twice if: You are on propane and want a plug-and-play installation; you will need to source an additional regulator for LPG use.

High Heat Champ

7. AMZCHEF 36 inch Gas Cooktop with 5 Made in Italy SABAF Power Burners, Max 48300 BTU/hr Built-in Gas Stove top with Double Sided Griddle

48,300 BTU TotalDouble Griddle

A 36-inch SABAF cooktop that pushes 48,300 total BTU and includes a reversible griddle for sear marks and pancakes.

AMZCHEF’s 36-inch gas cooktop features five SABAF burners with two high-output burners rated at 20,000 and 10,300 BTU, plus simmer burners at 7,000 and 4,000 BTU for delicate cooking. The total output of 48,300 BTU makes this among the most powerful cooktops in this roundup — one user highlighted the center burner was so hot it melted an old tea kettle handle, so keep an eye on heat-sensitive cookware. It comes with a double-sided reversible griddle made from cast iron and steel, giving you the option of ridge marks for steaks or a smooth surface for bacon and eggs.

The 304 stainless steel surface resists stains and discoloration, and the lift-up cleaning feature allows access under the sealed burners without lifting the entire unit. One buyer called it the best gas stove they have owned and noted that the high BTU burner made canning a breeze. The machine is ETL certified with a thermocouple flame-out failure device (FFD) that cuts gas automatically.

The built-in dimensions require a cutout of 32.87 by 19.09 inches, while the full product measures 35.43 by 20.08 inches and stands only 2.56 inches tall. The stainless steel is soft, according to one reviewer, so skip abrasive cleaners and use a spray cleaner instead to avoid scratches.

Where It Excels

  • 48,300 total BTU — among the highest outputs in the 36-inch class
  • Reversible cast iron griddle included for versatile cooking
  • Lift-up cleaning feature for access beneath burners

The Fine Print

  • Stainless steel surface scratches easily — avoid abrasive cleaners
  • Center burner extreme heat can damage thin or old cookware handles

Perfect for power seekers: If you want the hottest burners and a built-in griddle on a 36-inch platform, this AMZCHEF delivers flame output that rivals pro-style ranges at a mid-range price.

Who should skip it: If your cookware includes thin aluminum or vintage pots that cannot handle intense direct heat, the 20,000 BTU burner may be too aggressive for daily use.

Premium Mid-Range

8. GASLAND Gas Cooktop 30 Inch with Griddle, Gas Stovetop with 5 Burners, Reversible Cast Iron Grill/Griddle, Black

SABAF BurnersCSA Certified

A 30-inch SABAF five-burner showpiece with reversible griddle.

GASLAND’s PRO GH3305EFN cooktop features five Italian SABAF sealed burners, including a 13,000 BTU dual-ring wok burner and a 10,300 BTU high-output burner, plus 4,000 and 7,000 BTU simmer burners for precision low heat. The reversible cast iron griddle adds a ribbed side for steak sear marks and a smooth side for morning pancakes. The heavy-duty griddle with wide handles feels substantial and distributes heat evenly across the cooking surface.

The black enamel and 304 stainless steel surface resists heat and stains, and the sealed burners prevent food and liquid from falling into the interior — just lift the cast iron grates and wipe clean. The 4-foot 120V AC power cord supplies automatic electric pulse ignition. One buyer used this cooktop in a marine environment for two years and reported zero corrosion, which speaks to the build quality despite the mid-range pricing. Another reviewer noted the knobs and stems feel solid compared to many budget alternatives.

The flame failure detection system (thermocouple FFD) cuts gas if the flame goes out, and the unit is fully CSA certified for US and Canada. Product dimensions are 30 by 20 by 4.5 inches, and the required cutout is 28.6 by 18.9 inches. One small gripe from a reviewer: the knob range from LITE to LO is too short, making it difficult to maintain a true low simmer without nearly turning the burner off.

Why It Stands Out

  • Italian SABAF burners with powerful 13,000 BTU dual-ring wok burner
  • Reversible cast iron griddle included — ribbed and smooth sides
  • Rivals – models at a fraction of the cost, per buyers

One Drawback

  • Knob range from LITE to LO is insufficient for very low flame control
  • Some factory anomalies reported, though build quality is generally solid

A serious upgrade: If you want the look and feel of a premium cooktop without paying premium prices, the GASLAND PRO delivers SABAF burner performance, a reversible griddle, and CSA certification at a mid-range investment.

Be aware: The limited low-range knob action means you will need to pay closer attention when trying to maintain a barely-there flame for delicate sauces.

Pro-Grade Choice

9. ZLINE 36 in. Classic Gas Rangetop with 6 Burners and Porcelain Cooktop in Stainless Steel (RT36)

6 Italian BurnersLifetime Burner Warranty

Six Italian hand-cast burners that simmer at 1,000 BTU and sear at 18,000 BTU — the rangetop for serious home cooks.

ZLINE’s RT36 is a 36-inch gas rangetop (not a drop-in cooktop) with six Italian-made sealed burners that span a remarkable range: they simmer as low as 1,000 BTU and sear as high as 18,000 BTU. The heavy-duty, hand-finished porcelain one-piece cooktop makes cleaning straightforward — a simple wipe handles most messes. The premium-grade cast iron grates feel sturdy and sit solidly over the burners, and the tapered knob rings exude luxury while making operation easy.

It requires a dedicated 120V, 60Hz, 15-amp circuit with a NEMA 5-15 3-wire plug, and the 7.88-inch height means it sits higher than standard cooktops — confirm your counter depth before ordering. One shopper added excellent performance over 18 months of daily heavy use. The LP conversion kit is included but must be installed by a professional due to the rangetop’s gas system complexity.

ZLINE offers a limited lifetime warranty on its Italian burners, covering part replacements for burners and burner caps plus parts and labor for spark tips if defects are found. At 85 pounds, this is a heavy unit that requires solid counter support. Reviewers praise the packaging — it arrives well-protected and undamaged when shipped correctly.

Why It Commands Top Dollar

  • Six Italian hand-cast burners with 1,000–18,000 BTU range for simmer to sear
  • Lifetime warranty on Italian burners — class-leading coverage
  • 304-grade stainless steel resists rust and corrosion

What To Plan For

  • Requires a dedicated 15-amp electrical circuit — not a simple plug-and-play swap
  • 7.88-inch height is taller than standard cooktops — check counter clearance

For the dedicated home chef: If you want professional-grade flame control, the most burners in this roundup, and a lifetime warranty that backs its Italian engineering, the ZLINE RT36 is the rangetop that serious cooks buy once.

Consider carefully: The installation is more involved — you need a dedicated electrical circuit and professional propane conversion — so factor in both cost and complexity before committing.

Understanding the Specs

BTU and burner output

BTU (British Thermal Unit) measures how much heat a burner pushes out each hour. A higher number means faster boiling and better searing, but it also makes low-temperature simmering harder to control. Look for a cooktop that pairs at least one high-BTU burner (12,000 or above) with a dedicated low-BTU simmer burner (around 3,000 to 5,000) so you have both speed and precision. Total cooktop BTU — the sum of all burners — matters less than the range each burner offers individually.

Sealed burners and cleanability

A sealed burner has its gas tube and ignition enclosed under a metal cap, so spills stay on top of the cooktop surface instead of dripping into the burner mechanism. Every cooktop in this guide uses sealed burners, which makes cleanup as simple as lifting off the cast iron grates and wiping the stainless steel or enamel panel. Models with a smooth smooth surface or recessed burners take even less scrubbing time.

FAQ

What is the standard cutout size for a 30-inch gas cooktop?
Most 30-inch gas cooktops require a cutout roughly 28.5 to 29 inches wide by 19 inches deep, but each model varies. Always measure your counter and compare it to the manufacturer’s cutout template before ordering — several owners mention needing to widen the opening by 1/8 to 1/2 inch in older homes.
Can I install a gas cooktop myself?
If you are comfortable cutting countertop material and connecting gas lines under local code, the physical install is straightforward — many buyers do it in under an hour. The gas connection, however, should be done by a licensed professional unless you are experienced with gas fittings. Models with 120V plug-in ignition are simpler than hardwired units.
What does SABAF mean on a gas cooktop?
SABAF is an Italian manufacturer that produces sealed gas burners used by many cooktop brands. The name indicates the burner itself is made in Italy using SABAF’s engineering, which buyers often associate with consistent flame performance and durability. You will find SABAF burners on both budget-friendly and premium cooktops in this guide.
Is higher total BTU always better for a gas cooktop?
Not exactly — a high total BTU number is useful for boiling large pots quickly, but it can make simmering harder if the burners lack a low-end adjustment range. The best cooktop gives you both a high-output burner (12,000 BTU or more) for boiling and a low-output burner (under 5,000 BTU) for gentle cooking. A cooktop with all high-BTU burners will struggle to keep sauces from scorching.
How do I convert a gas cooktop from natural gas to propane?
Most cooktops ship pre-set for natural gas (NG) and include a conversion nozzle kit for liquid propane (LPG). The process involves swapping the small gas orifice nozzles under each burner cap and, in some cases, adjusting the regulator. Several buyers in this guide completed the conversion themselves in under an hour. Note that the regulator included with some models may be for NG only, requiring a separate propane regulator purchase.
What is a thermocouple flame failure device?
A thermocouple is a small sensor near each burner that detects whether the flame is lit. If a draft or spilled liquid extinguishes the flame, the thermocouple signals the gas valve to close within seconds, preventing a gas leak. This safety feature is standard on all models in this guide — look for it labeled as FFD, flame failure detection, or thermocouple protection.
How do I clean sealed burners on a gas cooktop?
Lift off the cast iron grates and wipe the burner caps with a damp cloth or mild detergent. Because sealed burners have no open holes or tubes where food can fall inside, you do not need to disassemble anything — the flat surface underneath wipes clean easily. Most customers note that cleaning takes only a few minutes per week. Avoid abrasive pads on stainless steel surfaces to prevent scratching.
Will a 36-inch gas cooktop fit in a standard kitchen counter?
A 36-inch cooktop needs a countertop cutout that is at least 34 inches wide and about 19 inches deep. Standard countertops can accommodate this, but you should check whether your cabinet base below leaves enough clearance for the cooktop’s depth — some 36-inch units, like the ZLINE RT36 at 27.5 inches deep, require deeper counters than typical drop-in models.
What does drop-in mean for a gas cooktop?
A drop-in gas cooktop sits inside a cutout in your countertop, with its edges resting on the counter surface. It is not a full range with an oven — it is just the cooktop surface. Most models in this guide are drop-in style, requiring a precise cutout and a gas line underneath. Rangetops like the ZLINE RT36 are a variation that slide in similarly but have a taller profile and often need an electrical circuit.
How long does a gas cooktop last before needing replacement?
A well-maintained gas cooktop with sealed burners typically lasts 10 to 15 years before burners or ignition components need attention. The cast iron grates may wear sooner depending on use frequency and cleaning habits. Buyers in this guide reported heavy daily use over 18 months with no degradation in performance, and one reviewer had been using a cooktop in a marine environment for two years without corrosion.

Final Thoughts: The Verdict

For most buyers, the best gas cooktop winner is the Frigidaire Gallery FGGC3645QS because it combines a trusted brand, straightforward propane conversion, and a proven 5-burner layout that gives you both searing and simmering without overcomplicating anything. If you want Italian SABAF burner quality and a reversible griddle, grab the 30 Inch Built-In Gas Cooktop with Griddle — its 20,000 BTU center burner outpaces most competitors near its price. And for the serious home cook who demands six burners with a pro-grade flame range and a lifetime burner warranty, nothing in this roundup beats the ZLINE RT36.
