Planning and project duration

A successful renovation begins with detailed planning. Generally, you should expect 2 to 4 weeks of construction during which your bathroom will not be usable.

During this phase, it is recommended to hire qualified professionals to ensure waterproofing and compliance with current standards. Anticipate daily logistics, as access to water or sanitary facilities will be restricted.

Good coordination between the plumber, electrician, and tiler is crucial to stick to the schedule. Use our RenoIndex estimator to define your overall budget.

The challenge of a walk-in shower

Replacing a traditional bathtub with a walk-in shower is a frequent request in Gossau, offering both space and aesthetics. However, this technical transformation requires checking the available drain slope in the floor thoroughly.

If the screed does not allow for a smooth flow, elevation solutions or specific pumps might be needed. It is essential to hire a professional to assess technical feasibility before purchasing your equipment.

Do not forget to check our RenoIndex tool to see how these technical choices can influence the final cost of your project.

Managing hard water in Gossau

The water hardness in the Gossau region can lead to the rapid build-up of limescale on your faucets and shower screens.

To minimize daily maintenance, opt for easy-to-clean materials, such as glass screens with anti-limescale treatments or high-quality, abrasion-resistant fittings.

Installing a water softener upstream of your home network can also extend the lifespan of your new equipment and protect your pipes. Remember to include these comfort options when calculating your costs on the RenoIndex website.

Budgeting and estimates

Renovating a bathroom is a significant investment that depends on the complexity of the work and the quality of the materials chosen. In Gossau, costs vary based on demolition, electrical upgrades, and the installation of new surfaces.

To obtain a realistic price range before contacting local companies, use our RenoIndex calculator. It allows you to better understand your overall financial framework by taking into account the specifics of your project.
