Sri Lanka’s home kitchens are changing. More families are replacing old freestanding gas stoves with built-in glass top cooker hobs. The look, function, and installation are all different. If you’re deciding between the two, here’s a clear comparison.
What is a glass top cooker hob?
A glass top cooker hob is a gas burner unit built into your countertop. The burners sit on a flat tempered glass surface. The glass is heat-resistant and easy to clean. The unit fits into a cut-out in your countertop and sits flush with the surface. No raised edges, no separate body below.
Most glass top hobs in Sri Lanka are 4-burner models. They run on LPG (bottled gas), same as a standard freestanding stove.
What is a freestanding gas stove?
A freestanding gas stove is a complete unit: burners on top, sometimes an oven below. It stands on the kitchen floor and connects to your gas line or LPG cylinder. It doesn’t integrate into your counter. It has a body, legs, and side panels.
Most homes in Sri Lanka have used freestanding stoves for generations. They’re practical, familiar, and easy to replace.
What is a Flame Failure Device (FFD)?
Most modern glass top hobs include a Flame Failure Device. FFD is a safety feature built into the gas valve. If a burner flame goes out, the FFD cuts the gas within seconds.
This prevents unburned gas from leaking into your kitchen if the flame dies unexpectedly.
Older freestanding stoves typically don’t have this feature. You have to notice the flame has gone out and turn off the knob manually. FFD removes that risk.
4-burner vs 2-burner: which suits your kitchen?
A 4-burner hob suits a family cooking multiple dishes at once. Most Sri Lankan households cook rice, a curry, a side dish, and a soup at the same time. Four burners covers all of that without juggling.
A 2-burner hob suits smaller kitchens, single people, or couples who cook simpler meals. It costs less and takes up less counter space.
Most families with three or more people choose 4-burner models.
Comparison: glass top hob vs freestanding stove
Cleaning
Glass top hobs are much easier to clean. The flat surface has no grates to remove, no drip trays to scrub, and no gap between the burner and the surface for food to fall into. You wipe the glass with a damp cloth after cooking.
Freestanding stoves have more surfaces and more places for grease to collect. Cast iron grates need scrubbing. Burner caps need soaking. The gaps around the burners collect everything.
Appearance
Glass top hobs give kitchens a cleaner, more modern look. The flush fit with the countertop makes the kitchen feel more open. This matters especially in smaller kitchens where every surface counts.
Freestanding stoves sit above the counter level. They don’t blend in with the counter. That’s fine for a functional kitchen but looks dated in a renovated space.
Safety
Built-in glass top hobs with FFD are safer than older freestanding stoves without this feature. FFD means gas stops automatically if the flame dies. For households with children, that’s a real difference.
Installation
Installing a glass top hob requires cutting a hole in your countertop. This is a permanent change. You need to hire a plumber or gas technician to connect the gas supply. It’s a one-time cost and process.
A freestanding stove just connects to the gas line or cylinder. You can move it. You can replace it without modifying your kitchen.
Cost
Built-in hobs cost more upfront than equivalent freestanding stoves. Most homeowners see it as a permanent upgrade rather than a regular replacement.
Cooking performance
Both run on gas. Cooking performance is the same. Heat output, flame control, and speed are comparable.
Who should switch to a glass top hob?
A glass top hob suits you if you:
- Are renovating your kitchen and want a modern look
- Want a safer option with FFD for a household with children
- Prioritise easy daily cleaning
- Don’t move home frequently
A freestanding stove suits you if you:
- Rent and can’t make permanent countertop modifications
- Move homes regularly
- Want the lowest upfront cost
- Need an oven in the same unit

Frequently Asked Questions
Can a glass top hob be used with induction cookware?
Only if it’s an induction hob. The glass top cooker hobs on ZUZU.LK are gas-burner units with a tempered glass surface, not induction. Any cookware material works: stainless steel, aluminium, cast iron, and non-stick pans are all compatible.
How fragile is the glass on a glass top hob?
Tempered glass is much harder to break than regular glass. It handles normal cooking safely. Avoid dropping heavy objects directly onto the surface. Also avoid thermal shock, which means pouring cold water onto a very hot glass surface. That can cause cracking.
Can you use a wok on a glass top hob?
Yes. A flat-bottomed wok works well on glass top gas burners. A traditional round-bottomed wok needs a wok ring to sit stably. High heat for wok cooking is fully supported. Glass top gas hobs reach the same temperatures as any gas burner.
Does gas or glass top use more gas?
The fuel consumption is the same. Both are gas hobs. The glass top unit is just a gas burner with a glass surface instead of a metal grate. Gas efficiency depends on the burner design and heat settings, not the surface material.
