Are you looking for a bathroom renovation in La Chaux-de-Fonds, or a tradesperson to redo the bathroom in a home in the town? This page sets out how the local building stock affects this kind of work. It also explains how to word your request so that you can compare quotes on a like-for-like basis.
Bathroom in La Chaux-de-Fonds: the most common jobs
The watchmaking town was laid out on a grid plan, which is a UNESCO World Heritage site together with Le Locle. It has many large rental buildings, where many bathrooms have changed little for a long time. Requests therefore often concern a complete replacement rather than a simple refresh.
The most frequent jobs:
- replacing the washbasin, WC and taps;
- removing a bathtub to replace it with a walk-in shower;
- redoing the waterproofing under and around the shower;
- laying new tiles on the floor and walls;
- upgrading the room’s ventilation;
- bringing the lighting and sockets in wet areas up to standard.
A bathroom brings together three trades: the plumber for the fixtures and pipework, the tiler for waterproofing and surfaces, and the electrician for the circuits. It is better to coordinate them in a single request rather than contacting them separately.
Rental buildings in La Chaux-de-Fonds: shared risers and neighbours
In a large building, the bathroom is not an isolated space. Water supply and drainage pipes often run through risers shared by several floors. Moving a WC or a shower may mean altering these connections, which also affects the neighbours above and below.
A few points to anticipate:
- a water shut-off sometimes affects several homes: the tradesperson informs the property manager or the co-ownership;
- noise from demolition work follows the house rules;
- protection of the common areas (stairs, lift) while the rubble is removed;
- a leak after the work can reach the flat below: waterproofing is not an item to economise on.
In a co-ownership, the risers are generally common parts: any work on them goes through the administrator or the owners’ meeting.
Long, snowy winters: what this changes for your bathroom
Winters in the Neuchâtel mountains are long and snowy. A bathroom there is used in a closed, heated home for much of the year, and steam-laden air cannot be cleared by simply opening the window wide. Ventilation is therefore a real issue: mechanical extraction or better-sized ventilation limits condensation, mould on the joints and damp on the external walls.
Cold also affects comfort. A tiled floor is cold in winter: ask the tradesperson whether electric underfloor heating or a heated towel rail connected to the existing heating is possible in your case. This is a job for the electrician and, depending on the choice, the heating engineer, and should be priced separately in the quote.
Finally, the work has to be planned with snow and ice in mind: lorry access, delivery of materials, parking in front of the building. Mention any access particularities (sloping street, floors without a lift) so that the quote takes them into account.
Older buildings, watchmaking heritage and procedures to check
The La Chaux-de-Fonds grid is part of the watchmaking heritage recognised by UNESCO. This does not mean that every interior job requires a permit, but the building envelope may be concerned. If your project alters a facade, a bathroom window facing the street or the structure, check before you start.
In the canton of Neuchâtel, building permit applications go through the cantonal SATAC one-stop office, with the decision issued by the municipality. For a simple replacement of fittings and finishes inside, the situation is in principle simpler, but only the municipality or the competent cantonal service can confirm what applies to your building. If your project includes a change of heating or hot water system, the cantonal energy and environment service runs a subsidy programme: check its conditions before signing, as some grants must be applied for before the work.
As for electricity, installations in wet areas follow the NIBT rules (the Swiss low-voltage installation standard). In an older home, the bathroom circuit may no longer meet current requirements: the electrician takes this into account in the offer.
Tenant, owner or co-owner: who decides?
- House owner: you decide, within the limits of building rules and heritage protection.
- Owner of a flat in PPE (condominium ownership): the co-ownership regulations set out what belongs to your unit and what is common; inform the administrator.
- Tenant: the written consent of the landlord or property manager is essential before any lasting work. Any contribution to the costs is discussed at that point.
Adapting the bathroom to stay at home
Many homes in La Chaux-de-Fonds have floors without a lift; for people who want to stay at home as they grow older, the bathroom is often the first room to adapt. A step-free shower is a better choice than a bathtub with a high rim. Grab bars, a shower seat, a non-slip floor and enough room to manoeuvre should be planned from the design stage. State this clearly in your request: the position of the pipework and the slope of the drain depend on this choice.
Preparing your quote request and comparing offers
To obtain comparable offers, describe:
- the type of home (rental building, co-ownership, house) and the floor;
- the approximate dimensions of the room and the current state of the bathroom;
- what you wish to change: fixtures, shower or bathtub, tiling, ventilation, lighting;
- your constraints: access, lift, staying at home, preferred schedule;
- your status (owner, tenant with the landlord’s consent, co-owner).
A good quote separates the items: demolition and removal, plumbing, waterproofing, tiling, electrical work, finishing, as well as supplies. It states whether the price of the fixtures is included or to be chosen later, and what is not covered. The cost varies with the surface area, the quality of the fixtures and tiles, any moving of pipework, the condition of the slab and walls revealed during removal, site access and the number of trades involved. Compare the content before comparing the total.
You can request a quote: your request is passed to tradespeople in the region, who will contact you to prepare a free, no-obligation offer.
