With a new bathroom (or a new kitchen), homeowners can modernize older houses or apartments at comparatively little expense. According to the life expectancy table, sanitary appliances last 20 to 50 years. So if you own a house or apartment built in the 1970s, 1980s or 1990s and have since then never renovated the bathroom, now is probably the time to do it. Often the bathtub, shower, vanity or toilet bowl are replaced earlier because they no wear down much faster and don't look very appealing anymore. A bathroom with modern plumbing reduces the total energy and water consumption, improves living comfort and increases the property's value.

  • ... the bathroom is angled instead of rectangular or square;
  • ... you want to change the floor plan to make the bathroom larger;
  • ... you want to cover the walls with expensive natural stone tiles up to the ceiling;
  • ... you want to replace the old tiled floor with a non-slip natural stone mosaic;
  • ... you want to add expensive extras like a whirlpool or a sauna.

How much does a basic bathroom cost?

Calculate roughly with 2,000 CHF per square meter. Thus, a basic bathroom measuring 12 square meters would roughly cost 24,000 CHF. This includes standard sanitary ware (a bathtub or shower, a single washbasin and a toilet) with simple fittings, a mirrored cabinet, a vanity unit and standard-sized tiles. Tiled only where it will be wet, all walls and ceilings are painted. With plaster walls or cement painting, you can even save the standard tiles and thus relieve your remodeling budget or afford something else.

How much does an average bathroom cost?

For an average bathroom you should calculate with approximately 3'000 CHF per square meter. A 12 square meter bathroom will then cost about 36'000 CHF. This includes upscale sanitary ware (a bathtub, perhaps even with whirlpool jets, a floor-level shower, a double washbasin for two and a toilet) with designer fixtures, a larger mirrored cabinet, something to put the laundry in and natural stone tiles on floor and walls. This budget should also be enough to be able to include some smaller extras like a heated towel rail or a rainforest shower.

How much does a luxury bathroom cost?

Calculate roughly with 4’500 CHF per square meter. A luxury bathroom measuring 12 square meters will therefore cost approximately 54'000 CHF. This includes exclusive sanitary ware (a bathtub with whirlpool jets or a bathtub and a whirlpool, a floor-level shower with frameless glazing made of safety glass, a double washbasin and a toilet) with high-quality fittings, a large mirror cabinet, if necessary with an interactive mirror, custom-made furniture for the laundry, non-slip natural stone tiles on the floor and seamless tiles on the walls. There could also be some money left in the budget for extras like a steam shower.

Depending on the extras, a luxury general overhaul can cost 100,000 CHF or more. If for example, you have new connections put in, underfloor heating or ambient lighting installed that you can control with your smartphone depending on your mood.
