Short answer: All three brands sell professional-style freestanding ranges in common 30", 36", and 48" widths. ILVE is the Italian-made, highly customizable option (five widths up to 60", 216 custom colors) with a 2-year parts-and-labor warranty. FORNO offers a wide mix of fuel types (gas, dual fuel, electric, induction) with a 2-year warranty on many freestanding ranges. ZLINE ranges carry a 1-year parts-and-service warranty plus a limited lifetime warranty on gas burners. Pick by size, fuel, and finish first, then compare warranty terms.

Warranty note: Warranty terms are set by the manufacturer. Ask us before you buy and we will confirm coverage for your order. Manufacturer pages may require purchase through an authorized channel.
Measure the opening and check the exact model's spec sheet for width, depth, and clearances to combustible surfaces. A 30" and a 36" range are not interchangeable without cabinet work.
Converting between natural gas and propane needs the right kit and a licensed installer. Gas and electrical hookups should always be done by a licensed installer and checked against local code.
48" and wider ranges usually split into two ovens. ILVE's Majestic offers double ovens up to 60".
Higher-BTU ranges need more hood airflow. Hoods capable of more than 400 CFM can trigger make-up air rules. Use our range hood CFM calculator.
Compare length and what is covered (parts only vs parts and labor), who must do the service, and whether purchase channel affects coverage.
It depends on size, fuel, finish, and budget. Compare widths, fuel types, oven setup, and each maker's published warranty terms rather than ranking brands.
ILVE lists 60-inch models in Majestic, Nostalgie, and Professional Plus. Our catalog also includes 60-inch FORNO models. Confirm the exact model on the product page.
Per maker pages checked Oct 26, 2026: ILVE and FORNO list 2-year terms on many freestanding ranges; ZLINE lists 1 year parts and service plus a limited lifetime warranty on gas burners. Warranty eligibility is set by the manufacturer.
Gas needs a gas line sized for total BTU. Dual fuel needs gas plus a dedicated electrical circuit for the oven. Check the model spec sheet and have a licensed installer confirm your home can supply both.
