The funding applies specifically to bathroom renovations and measures in the sanitary sector, such as changing the layout of the room, installing floor-level showers or modernizing sanitary objects. Natural persons, regardless of age or disability, who are the owners of a one- or two-family house with a maximum of two residential units or a condominium in a homeowners’ association are eligible to apply. People who rent an apartment or a single-family home can also benefit from the funding.
