La Cornue Château 75 vs 90
La Cornue Château 75 vs 90 is a common question among La Cornue owners. This guide walks through it step by step with technician-grade detail.
The Château 75 and Château 90 sit at the heart of the La Cornue lineup. Both are single-vaulted-oven ranges, but the extra 15 centimeters of the 90 change what you can fit on the rangetop and inside the oven. This guide compares them directly.
Château 75 (29.5″ / 75cm)
The Château 75 is the entry into the classic vaulted-oven experience. It offers one vaulted oven and rangetop configurations B1 through B3, plus BA and BB layouts. It suits kitchens where space is at a premium but the cook still wants a genuine made-to-order Château with the voûte oven and configurable modules.
Château 90 (35.4″ / 90cm)
The Château 90 steps up to a grand vaulted oven with noticeably more capacity, and rangetop configurations C1 through C3, C5, plus CI (induction) and CC layouts. The wider hob accommodates a more ambitious mix of modules — for example, a French Top alongside gas burners, or an induction section. For many buyers the 90 is the sweet spot between capacity and footprint.
Side-by-side
- Oven: 75 = single vaulted oven; 90 = single grand vaulted oven (larger capacity).
- Rangetop width: 90 offers more room for module combinations.
- Configurations: 75 uses B-series layouts; 90 uses C-series layouts including induction (CI).
- Footprint: The 75 fits tighter spaces; the 90 needs more wall and clearance.
Which should you buy?
Choose the 75 if your kitchen is space-constrained or you cook for a smaller household and want the Château experience at the smallest footprint. Choose the 90 if you regularly roast large cuts, entertain, or want flexibility to combine a French Top with burners or induction. If you are weighing the next size up, see our Château 90 vs 120 comparison.
Configuration and finish
Both sizes are made to order with the full palette of enamel colors and trim metals (polished or brushed brass, nickel, chrome, copper, and more). Because they are bespoke, plan for a lead time. You can explore live specifications on lacornueusa.com and view configured units on our model pages.
Owning and servicing either size
The vaulted oven and brass burners on both ranges reward regular maintenance. When you need professional attention — igniter service, thermostat calibration, or enamel care advice — our technicians service the entire Château line. Schedule a visit to keep your range performing like the day it left France.
Capacity in everyday cooking
The practical difference shows up at holidays and dinner parties. The 90’s grand vaulted oven swallows a large roast or multiple sheet trays with room for radiant heat to circulate, while the 75’s single vaulted oven is better matched to weeknight cooking and smaller households. If you regularly cook for a crowd, the extra oven volume on the 90 is the feature you will notice most. Both deliver the same enveloping, window-less voûte heat — see our how the vaulted oven works guide.
Rangetop flexibility
The 90’s wider hob (C-series layouts, including the CI induction option) lets you combine more modules at once — for example a French Top beside a pair of brass burners, or burners plus an induction section. The 75’s B-series layouts are more constrained but still cover the essential combinations. If you dream of orchestrating several cooking methods simultaneously, the 90 gives you the room; our rangetop configuration guide walks through the modules.
Frequently asked
- Is the 75 a “lesser” Château? No — it is a genuine made-to-order vaulted-oven range, just at the smallest footprint.
- Will the 90 need a bigger hood? Yes, size the hood to the wider 90; under-venting a powerful range leaves grease and odor behind.
Resale and long-term fit
Both sizes are made to order with the full enamel palette and trim metals, so both can be configured as genuine showpieces. The 90’s extra capacity and module flexibility tend to suit households that entertain or expect their cooking to grow, while the 75 is the smart pick where space is genuinely tight and the cook values footprint over maximum oven volume. Either way you are choosing within the single-vaulted-oven tier; if your needs point toward two ovens, that is the cue to look at the dual-fuel Château 120 instead.
