Bathroom renovation in Geneva
Planning building work? Apartment, house or building renovation, a new storey or a roof extension, running the project is our job.
HMG Construction Management SA runs your bathroom renovation in Geneva, from the survey to acceptance. The firm defines the works, prices each trade, selects the contractors, sets the sequence of work and checks the waterproofing, the connections and the finishes before the room is handed back.
How do you get your bathroom renovation done without the worry? By handing the management and the coordination of the contractors to HMG. HMG is there for you.
What are the steps of a bathroom renovation?
A bathroom brings many trades together in a few square metres. The plumber, the electrician, the plasterer, the waterproofer, the tiler, the joiner and the painter follow each other in a precise order. A mistake in the order means taking down what has just been fitted.
Quality depends on what can no longer be seen at the end, namely the drainage falls, the waterproofing under the tiles, the ventilation and the exact position of the supplies. HMG checks these points while they are still visible.
Permits and procedures in Geneva
Replacing the sanitary ware and the coverings of an existing bathroom counts as maintenance. Creating an additional bathroom, moving the room or changing the partitions alters the interior layout of the home. These works fall under the fast-track APA procedure set out on the official permit types page of the Canton of Geneva.
In a block of flats, the property manager (régie) or the condominium (PPE) has to agree to any work on the supply and waste risers, which also serve the neighbours. Water shut-offs are announced in advance. Our guide to building permits and procedures gives the detail.
Who do you call first?
- HMG takes charge of the whole project, from the plans to the end of the works, including the permit application where one is needed.
- You have an architect or an interior architect. They design the room, and HMG organises and checks the construction with them.
Either way, you do not have to find and coordinate six or seven trades yourself.
How HMG manages your bathroom renovation
HMG draws a dimensioned plan of the room showing the position of every appliance, supply and socket. On that basis, the firm asks for comparable bids, helps you choose appliances and coverings within your budget, and orders the long lead items.
The site follows a day by day schedule. HMG accepts the substrate before the waterproofing, the waterproofing before the tiling, and the connections before the ducts are closed. At the end, the firm tests the drains and the appliances, draws up the snag list and follows it through.
Usual steps and timing
- Visit, survey and check of the condition of the pipes.
- Plan of the room, choice of appliances and cost estimate.
- Contractors' bids, contracts and orders.
- Demolition, plumbing and electrics.
- Plastering, waterproofing, floor and wall tiles.
- Fitting of the appliances, furniture and accessories, then acceptance.
The duration depends mostly on the condition of the pipes found at demolition and on drying times. HMG allows for these in the schedule, so that the announced end date is kept.

Frequently asked questions
Can a bathtub be replaced by a walk-in shower?
Yes, if the depth available in the floor allows the fall and the drain to be created. HMG checks this at the first visit. In a block of flats, the position of the waste riser often dictates where the shower can go.
Do we have to inform the property manager or the condominium?
Yes, as soon as the works touch the risers or the ventilation, or require a water shut-off. HMG prepares the request, announces the shut-offs and has the condition of the common parts recorded before the works.
How do you avoid leaks after the works?
By checking the waterproofing before the tiles are laid and by testing the connections under water. HMG documents these checks with photos, which you keep with the building file.
How much does a bathroom renovation cost in Geneva?
The price depends on the condition of the pipes, the floor area and the choice of appliances and coverings. HMG gives you an estimate by trade, then a budget based on contractors' bids.
