Are you looking for a kitchen renovation in Sion, whether your home is a small flat in the centre, an apartment block in a residential district or a villa on the hillside? This kind of project combines strip-out, plumbing, electrics, fitting and finishes, and each building brings its own constraints. This page describes what Sion’s building stock changes in practice for a kitchen project, then how to prepare a request and compare offers.

Kitchens in Sion: from the old town to villas

As the capital of Valais, Sion has very different types of housing, and a kitchen is not renovated in the same way in each.

In the old town, at the foot of the Valère and Tourbillon hills, the buildings are old and the rooms often narrow. The kitchen there is sometimes small, opening onto a corridor or tucked into a corner. The work is then about making the most of every centimetre: made-to-measure units, compact appliances, high-level storage. A standard layout does not always fit, and the contractor needs to measure on site rather than estimate from a plan.

In apartment-block districts, the kitchen is generally a closed or semi-open space, with existing connections that you usually want to keep. Leaving the sink, the waste stack and the gas or electricity supply where they are limits the interventions, and so the disturbance to neighbours. Conversely, moving the sink or opening the kitchen onto the living room calls for an analysis of the walls involved and, in co-ownership, the opinion of the owners’ association.

In villas there is more room to manoeuvre: open-plan kitchen, central island, longer worktop, more appliances. The project can go as far as a complete redesign of the ground floor. The trade-offs then concern style and materials more than available space.

Kitchen work in Sion’s building stock

Whatever the shape of the home, the list of tasks remains similar:

  • stripping out the old kitchen and removing the elements;
  • plumbing: water supply, waste pipes, dishwasher connection;
  • electrics: dedicated circuits for large appliances, worktop sockets, lighting;
  • fitting: base and wall units, doors, worktop;
  • appliances: oven, hob, fridge, dishwasher;
  • tiling or a splashback between the worktop and the wall units;
  • ventilation or an extractor hood, with its outlet or filter.

In an older building, strip-out sometimes reveals surprises: an uneven wall, an ageing pipe, an outdated electrical panel. This is not specific to Sion, but the city’s building stock, where old buildings stand alongside more recent ones, makes such cases frequent. Ask for the quote to say how these unforeseen items are handled and invoiced.

Sion and the Rhône valley: what the climate changes for a kitchen

Sion lies in the Rhône valley, where the climate is dry and sunny, with hot summers. For a kitchen, this affects two points in particular.

The first is heat. An oven, a hob and a dishwasher running in summer in an already warm home quickly make the room uncomfortable. Good ventilation or an efficient hood, properly sized and properly vented, becomes more than a detail. Discuss it with the contractor from the outset: the choice between venting outside and recirculation depends on what the building allows, and in an apartment block on what the owners’ association accepts for openings in the façade.

The second is exposure. In a kitchen with a lot of sunlight, the unit doors and the worktop are exposed to light for much of the day. Ask the supplier how the materials and colours hold up in these conditions rather than relying on the sample alone seen in a showroom.

The dry climate does not remove the need to check the condition of the waste pipes and the seals around the sink: a slow leak behind a unit can go unnoticed for a long time, whatever the weather outside.

Permit, landlord, co-ownership: the procedures for your kitchen in Sion

The procedures depend on the nature of the work and on your status.

Permit. In Valais, the building permit is issued by the commune within the building zone, and by a cantonal commission outside it. Replacing units and appliances like for like does not generally fall under the same requirements as a transformation affecting the structure or the appearance of the building, but only the authorities can confirm this for your case. If your home is in the old town or in a protected building, ask the question before any commitment. For a chalet or a second home, federal rules apply in the communes concerned: check with the commune or the relevant cantonal department whether they apply to you.

Energy. If your project also includes appliances or heat production linked to energy, the cantonal energy and hydropower department runs a subsidy programme. Find out about its conditions before ordering, as they rarely apply after the fact.

Tenants. You need the written consent of the landlord or the managing agent, with details of what is allowed and what must be reinstated when you leave.

Co-owners. Work within your own unit is in principle your own affair, but anything affecting the common parts (risers, façade, ventilation duct) may require the agreement of the owners’ association. Consult your regulations and your administrator.

Preparing your request and comparing kitchen quotes in Sion

The more precise your request, the more comparable the offers you receive will be. Describe:

  • the type of home (flat, older building, villa) and the floor;
  • the approximate dimensions of the kitchen and what you want to keep or move;
  • the appliances you want or have already bought;
  • whether you want a single point of contact for all trades or will coordinate them yourself;
  • your status (owner, tenant, co-owner) and where things stand with the landlord’s or owners’ association’s consent;
  • photos and your access constraints: stairs, lift, narrow street in the centre.

A good quote itemises each line: strip-out and removal, plumbing, electrics, units, worktop, appliances, splashback or tiling, ventilation, finishes. It states what the company supplies and what you provide, how unforeseen items are handled and which points remain your responsibility.

The cost of a kitchen varies mainly with the extent of the plumbing and electrical work, the choice of units and worktop, the level of the appliances, the number of trades involved and the accessibility of the home. There is no right figure outside of a context: only a quote prepared for your project tells you anything. Offers are free and without obligation, so you can ask for several.

To get started, you can request a quote: you describe your work online, and your request is passed on to craftspeople and companies in the area, who will contact you.

Frequently asked questions

Do I need a permit to redo a kitchen in Sion?
It depends on the scale of the work. Replacing units and appliances does not have the same consequences as moving a partition wall, altering a façade or working in a protected building. Within the building zone, the building permit is issued by the commune: check with the relevant communal department before you start.
I am a tenant in Sion: can I renovate my kitchen?
Only with the written consent of your landlord or the managing agent. This document should state what is allowed: replacing the units, moving the sink, new appliances, and any reinstatement at the end of the lease. Keep a copy before ordering anything.
Is a kitchen in an older building in Sion harder to redo?
Often, yes. The walls, floors and water or electrical risers of an older building are not always square or up to current standards, which sometimes only comes to light during strip-out. Ask the contractor how they handle these surprises in their quote.
Who coordinates the different trades for a kitchen?
A kitchen involves several trades: plumbing, electrics, fitting, tiling and ventilation. Either one company takes on the coordination and you have a single point of contact, or you manage it yourself as the client. State your preference in your request.
How do I compare two kitchen quotes?
Check that both cover the same scope: strip-out and removal, connections, units, worktop, appliances, splashback, extractor hood and finishes. A less detailed quote is not necessarily better value, as missing items often come back as extras.
