Attefall house with a toilet

Every house we build has a separate toilet room with WC and washbasin, fitted before delivery. For it to work, a connection to drainage and water on the plot is needed. Installing water and drainage may require a notification to the municipality.

Notification

Boverket states that a notification may be required when water and drainage are installed or changed. Private sewage systems are also reviewed by the municipal environment committee. Start by asking the municipality what applies to your property.

Shower?

Whether a shower can be included in the toilet room depends on the specification and the water connection. We confirm it in the quote and promise nothing we cannot deliver.
