Smeg Oven Cucina - Silver vs 70L Built-In Electric Single Oven — Comparison

DUSF400S and SF6400TB compare two very different Smeg built-in oven formats. The Smeg DUSF400S Oven Cucina - Silver costs £1129 and is the double oven choice in the Cucina style, aimed at buyers who need two separate cavities. The Smeg SF6400TB 70L Built-In Electric Single Oven costs £419 and is the more affordable single oven model, positioned for kitchens where one large cavity and modern convenience features are enough.

The DUSF400S provides double oven functionality with 35L and 61L oven capacities, an 1800W grill, Easy Clean Enamel interior and DigiScreen Timer. The SF6400TB has a single 70L capacity, Vapour Clean, thermo-ventilated cooking, rapid pre-heating and an A energy rating. The DUSF400S has 96L combined capacity across two compartments and a stated grill wattage, while the SF6400TB has the larger individual cavity and adds rapid pre-heating plus vapour-based cleaning assistance.

The DUSF400S suits families and traditional cooks who value the flexibility of using two temperatures or cooking zones at once. Its 35L top oven can handle grilling or smaller dishes while the 61L main oven manages roasts and bakes. The SF6400TB suits buyers who want Smeg styling and practical features without the double oven price. It is £710 cheaper, has a larger single cavity than either DUSF400S compartment, and is easier to justify for everyday traybakes, pizzas, vegetables and single-dish meals. The trade-off is losing separate-cavity cooking.

Bottom line: choose DUSF400S if you need a double oven with 35L/61L cavities and an 1800W grill / opt for SF6400TB if you want a cheaper 70L single oven with Vapour Clean and rapid pre-heating.
