What is the kitchen work triangle?
The kitchen work triangle connects the three most-used stations in a kitchen: the hob (cooking), the sink (washing), and the fridge (storage). Each side of the triangle should measure between 1.2 and 2.7 metres, and the total perimeter should not exceed 8 metres. This arrangement ensures you can move efficiently between the three stations without taking unnecessary steps. The work triangle is not a rigid rule — in larger kitchens with islands, it evolves into work zones — but for most home kitchens it remains the best starting point for layout planning.
What are the minimum clearances for kitchen units?
The minimum gap between two facing runs of kitchen units (such as in a galley kitchen) is 1,000 mm. Ideally, this should be 1,200 mm if two people use the kitchen at the same time. Between an island and the perimeter units, allow at least 1,000 mm on all sides. In front of an open oven or dishwasher door, you need 1,000 mm of clear standing space. These clearances ensure you can move safely, open doors and drawers without obstruction, and work comfortably.
What is the minimum size for a bathroom?
A cloakroom (WC and basin only) can work in as little as 1.2 x 0.8 metres, though 1.5 x 1.0 metres is more comfortable. A full bathroom with a bath, toilet, and basin typically needs at least 2.4 x 1.8 metres. An en-suite with a shower, toilet, and basin can work in 1.8 x 1.5 metres if space-saving fixtures are used. These are minimums — more space is always better for comfort and accessibility.
How much space do I need around a toilet?
Allow a minimum of 600 mm of clear space in front of the toilet pan for comfortable use. From the centre of the pan to any side wall or adjacent fixture, allow at least 200 mm — ideally 375 mm for comfort. The toilet also needs enough space behind it for the cistern (approximately 200 mm for a close-coupled toilet, or flush to the wall for a concealed cistern). These clearances ensure the toilet is comfortable to use and that the bathroom feels spacious rather than cramped.
Should the toilet face the bathroom door?
Ideally, no. The toilet should not be the first thing you see when you open the bathroom door. It is more pleasant if the basin or a clear floor area is visible first, with the toilet tucked to one side or behind the door. This is an aesthetic preference rather than a rule, and in very small bathrooms it may not be possible — but if you have a choice, position the toilet away from the direct line of sight from the door.
Do I need planning permission to renovate a kitchen or bathroom?
In most cases, no. Replacing a kitchen or bathroom within the existing room layout does not require planning permission, provided you are not making structural changes (such as removing a load-bearing wall) or significantly altering the external appearance of the property. However, electrical work in kitchens and bathrooms must comply with Part P of the Building Regulations in England and Wales, and gas work must be carried out by a Gas Safe registered engineer. If you are moving plumbing significantly or altering the building structure, check with your local building control office.
What is the best kitchen layout for a small kitchen?
A galley layout (two parallel runs of units facing each other) is typically the most efficient for small kitchens. It keeps everything within easy reach and makes excellent use of narrow spaces. If the room is too narrow for a galley (less than about 2.4 metres wide), an L-shaped layout using two adjacent walls is the next best option. Avoid islands in kitchens under 4 metres wide — they create more problems than they solve in tight spaces. See our kitchen planner guide for detailed layout advice.
How do I plan bathroom ventilation?
Every bathroom needs adequate ventilation to prevent mould, damp, and condensation. If the bathroom has an openable window, this provides natural ventilation, but a mechanical extractor fan is still recommended — especially for bathrooms used by multiple people or for long showers. The fan should be rated for the room size (typically 15 litres per second for a bathroom) and ideally connected to a humidistat so it runs automatically when moisture levels rise. Position the fan on the wall or ceiling opposite the main moisture source (usually the shower or bath) for the most effective extraction.
What clearance do I need in front of a basin?
Allow a minimum of 700 mm of clear floor space in front of the basin. This gives you enough room to stand comfortably, lean forward to wash your hands or face, and bend to access under-basin storage. If the basin is in a narrow space (such as opposite a toilet or bath), ensure the combined clearance between the two fixtures still allows comfortable use of both.
Can I move the kitchen sink to a different wall?
Yes, but it involves rerouting the waste pipe and possibly the water supply pipes. The waste pipe needs a gradient (fall) of at least 1 in 80 to drain properly, so the further the sink moves from the existing waste connection, the more complex the plumbing becomes. If the new position is on the same wall or an adjacent wall, the work is usually straightforward. Moving it to the opposite side of the room may require routing pipes under the floor, which is more disruptive and expensive. Discuss the feasibility with a plumber before finalising your layout.
What height should kitchen worktops be?
The standard kitchen worktop height in the UK is 910 mm from the floor. This suits most adults of average height. If you are taller or shorter than average, consider adjusting the worktop height for comfort — working at a surface that is too low causes back strain, and one that is too high causes shoulder strain. Some kitchen designs incorporate two worktop heights: a standard height for general preparation and a lower height for baking or seated work.
Should I choose a bath or a shower for a small bathroom?
If the bathroom is very small (under 3 square metres), a shower is almost always the better choice. A standard UK bath is 1,700 mm long and takes up nearly half of a small bathroom. Replacing it with a 900 x 900 mm shower enclosure frees up significant floor space for storage, a larger basin, or simply more room to move. If you strongly prefer a bath, consider a shorter bath (1,500 mm or even 1,200 mm) or a shower-bath combination. In a family home with children, having at least one bath somewhere in the house is generally advisable.
How do I plan lighting for a kitchen?
Kitchen lighting should combine ambient lighting (ceiling downlights or a central pendant for overall illumination), task lighting (under-cabinet LED strips or spotlights to illuminate worktops), and accent lighting (inside glass-fronted cabinets, above open shelving, or as decorative pendants over an island). Plan lighting positions at the same time as the kitchen layout — retrofitting lights after cabinets are installed is difficult and expensive. Ensure task lighting is directly above the worktop edge, not behind your head where it would cast shadows while you work.
What are bathroom electrical zones?
UK bathrooms are divided into electrical zones that determine what types of electrical equipment can be installed where. Zone 0 is inside the bath or shower itself — only SELV (Separated Extra Low Voltage) items are permitted here. Zone 1 is directly above the bath or shower to a height of 2.25 metres — IPX4 rated items (splash-proof) are required. Zone 2 extends 600 mm horizontally from Zone 1 — IPX4 items are also required here. Beyond Zone 2, standard rules apply, but sockets must be at least 3 metres from Zone 1. These zones exist to prevent electrocution and are a legal requirement, not a suggestion. Always consult a qualified electrician for bathroom electrical work.
