Kitchen Renovation: Layout, Ergonomics, Materials and Budget
The kitchen is the heart of the home and, after the bathroom, the most technically complex room. Water, drainage, high-power electrics, ventilation and often gas all work here. A well-planned kitchen saves time every day, while mistakes — a socket behind the fridge or a sink far from the dishwasher — will annoy you for years. Here's how to plan a kitchen, choose materials and stay within budget.
Step 1. Define How You'll Use It
- How many people cook at once, and how often?
- Do you need a dining area in the kitchen, or is it in the living room?
- What appliances do you need: dishwasher, eye-level oven, microwave, coffee machine, washing machine?
- How much storage for food, dishes and cleaning products?
The answers determine the layout and budget.
Step 2. Choose a Layout
- Single-wall (linear) — everything along one wall. Suits narrow kitchens and studios.
- L-shaped — the most versatile option for typical 7–10 m² kitchens.
- U-shaped — maximum worktop and storage, needs a width of at least 2.4 m.
- Galley (two-row) — for long narrow kitchens; at least 1.2 m between rows.
- With an island or peninsula — for spacious kitchens and kitchen-living rooms; an island needs 90–100 cm clearance on all sides.
The Work Triangle
The classic rule: the fridge, sink and cooktop form a triangle whose sides total 4 to 7 meters, with no obstacles between them. The optimal sequence of zones: storage (fridge) → sink → preparation (worktop) → cooking (cooktop) → serving.
Kitchen-Living Room
Merging the kitchen with a room is popular but requires redevelopment. If there's a gas stove, extra requirements for separating the rooms apply. Details in apartment redevelopment.
Step 3. Ergonomics
- Worktop height — usually 85–95 cm; a guide is 10–15 cm below the elbow of the person who cooks most.
- Worktop depth — 60 cm standard, 65–70 cm gives more space.
- Distance from worktop to wall cabinets — 50–65 cm.
- Distance from cooktop to hood — per the manufacturer's instructions (usually 65–75 cm for gas, less for electric).
- Worktop between sink and cooktop — at least 60–90 cm.
- Sink and dishwasher — next to each other so you don't carry dishes across the kitchen.
Step 4. Electrics
The kitchen is the apartment's biggest electricity consumer. Plan:
- dedicated circuits for the induction cooktop, oven, dishwasher and washing machine, with breakers of the right rating and cable cross-sections matched to the load;
- residual current devices for circuits near water;
- sockets above the worktop — at least 4–6 per kitchen, allowing for small appliances;
- sockets for built-in appliances — in adjacent cabinets so they're accessible;
- outlets for task lighting and the hood.
Position sockets according to the kitchen design before plastering. How to design the electrical network is covered in apartment electrical wiring.
Step 5. Water and Drainage
- Place the sink close to the riser if possible: the drain needs a slope, and long horizontal runs clog.
- Provide outlets for the dishwasher, a drinking water filter and a fridge with an ice maker.
- Install a leak protection system under the sink.
Step 6. Ventilation and the Hood
Cooking releases moisture, grease, odors and combustion products. The US Environmental Protection Agency (EPA) recommends using a hood vented to the outside while cooking to reduce indoor air pollution.
- A ducted hood is more effective, but don't connect it to the building's shared ventilation duct without a technical solution — it disrupts natural ventilation in neighbors' apartments. Ideally use a separate duct or an outlet through the wall where permitted.
- A recirculating hood with a carbon filter needs no duct but copes worse with moisture and requires regular filter changes.
- Hood capacity is calculated from the kitchen volume — a guide is 10–12 air changes per hour.
Step 7. Gas Safety
If the kitchen has a gas stove:
- any work on gas pipes and appliances must be done only by the gas distribution company or a licensed specialist;
- gas pipes can't be walled in without access;
- install a gas detector with an automatic shut-off valve;
- ensure supply air and working ventilation;
- don't enclose the gas meter behind solid fronts without ventilation.
General fire and technological safety requirements are set by the Civil Protection Code of Ukraine. Many owners give up gas during renovation in favor of induction — it's safer and allows freer kitchen-living room planning.
Step 8. Materials
Fronts
- Melamine-faced chipboard — the most affordable option, durable for everyday use.
- PVC-wrapped MDF — a wide choice of colors, but the film may peel near the oven.
- Painted MDF — a premium look in any color, needs careful handling.
- Veneer and solid wood — natural, expensive and need care.
- High-pressure laminate (HPL) — very resistant to scratches and moisture.
Worktop
- Chipboard with HPL surface — affordable but sensitive to water at the joints.
- Quartz composite — strong, non-porous and hygienic.
- Solid surface (acrylic stone) — seamless and repairable, but sensitive to high heat.
- Natural stone — granite is tough, marble needs caution.
- Solid wood — warm to the touch, needs regular oiling.
Splashback
Tiles, glass, a quartz panel or washable paint. The key requirements are resistance to grease and moisture and easy cleaning.
Floor
Tiles or vinyl flooring are the best options for a kitchen. More in our flooring guide.
Step 9. Appliances
- Choose built-in appliances before ordering furniture — niche sizes depend on the models.
- Pay attention to energy efficiency: the fridge runs around the clock, and the consumption difference between classes is noticeable. The ENERGY STAR program provides useful guidance.
- An induction cooktop is fast, safe and energy-efficient.
- A dishwasher saves water compared with washing by hand.
Step 10. Lighting
- General — ceiling lights.
- Task — LED lighting under wall cabinets, without shadows on the worktop.
- Decorative — pendants over the island or dining table.
Organizing Storage
Even a big kitchen feels cramped if storage is poorly planned. A few principles:
- drawers instead of shelves in base units — everything is reachable without kneeling;
- corner mechanisms — carousels or pull-out baskets use dead corners;
- a tall larder unit for food and built-in appliances — maximum space on minimal wall area;
- organizers for cutlery, lids and spices;
- a waste sorting module under the sink;
- rails and magnetic holders for knives and everyday utensils.
Plan what goes where at the design stage: dishes next to the dishwasher, pans next to the cooktop, food next to the fridge.
Planning for Power Outages
Blackouts have added a new item to kitchen planning. Worth considering:
- a dedicated socket or circuit for the fridge connected to a backup power source (inverter or power station), so food stays cold during outages;
- a portable gas or induction-compatible camping stove stored in an accessible cabinet;
- battery-powered LED strips under wall cabinets for basic lighting;
- a hood and cooktop that restart correctly after power is restored (check the manual for auto-restart behavior);
- a water supply for a few days in a convenient spot — especially in high-rises where pumps may stop.
A Kitchen for Renting Out or Selling
If the apartment is for rent, choose hard-wearing, easy-care materials: chipboard with an HPL worktop, a tiled splashback and basic reliable appliances. Neutral colors appeal to most tenants and buyers. More in renovation for rental.
Budget
Main items:
- kitchen furniture — the biggest share;
- worktop;
- appliances;
- sink and faucet;
- wall, floor and splashback finishes;
- electrics, plumbing, ventilation;
- lighting;
- a 10–15% contingency.
Made-to-order furniture usually takes 4–10 weeks, so order it in parallel with the rough works after precise measurements.
Common Mistakes
- Too few sockets, or sockets behind appliances.
- No space for small appliances on the worktop.
- The fridge next to the cooktop or oven.
- Front handles hitting the wall or a door.
- Connecting the hood to the shared ventilation duct.
- A light-colored porous worktop that stains.
- Ordering furniture before windows are installed and walls leveled.
- No access to valves, meters and drain cleanouts behind the furniture.
Frequently Asked Questions
What comes first — furniture or renovation? First the furniture design, then utilities routed to match it, then finishing, and only then precise measuring and manufacturing of the furniture.
Should wall cabinets go up to the ceiling? Yes, if the ceilings aren't too high: extra storage and no dust on top of the cabinets.
Is an island a good idea in a small kitchen? Only if the clearance around it is at least 90 cm. Otherwise a peninsula or a mobile table is better.
How do I refresh a kitchen without replacing it? Paint the fronts, replace the handles, splashback and lights — see DIY cosmetic renovation.
Induction or gas? Induction is safer, heats faster, cleans more easily and doesn't pollute the air with combustion products. Gas is cheaper to run at current tariffs and works during power outages (if it has no electric ignition). A compromise is a combined cooktop or induction plus a portable gas stove for blackouts.
How much does a kitchen renovation cost? It depends on the area, materials and appliances. Furniture and appliances usually make up the largest share, so compare several quotes from furniture makers for the same design.
Conclusion
A good kitchen starts with planning: how you'll use it, the work triangle, ergonomic heights, enough sockets and well-thought-out ventilation. Then come practical materials and energy-efficient appliances. Follow the "design — utilities — finishes — furniture" sequence, and your kitchen will be convenient and beautiful for years.
