## Abstract

A method and a wall element for repairing a wall structure comprising at least an inner metal sheet, an outer metal sheet and an insulator layer between the inner and outer metal sheets. The method comprises at least the following steps: (i) removing the inner metal sheet in such a way that installation frames formed on the inner metal sheet are left in the wall structure, (ii) removing the insulator layer from a place where the inner metal sheet has been removed, (iii) installing a wall element comprising a metal sheet and an insulator layer attached to the metal sheet in the place of the removed wall structure in such a way that the edges of the metal sheet of the wall element are placed overlappingly with the installation frames.

## Claims

### Claim 1

A method for repairing a wall structure (202) of a sanitary unit of a cabin comprising at least an inner metal sheet (406) forming the wall surface of the sanitary unit, an outer metal sheet (402) and an insulator layer (404) between the inner and outer metal sheets, which method comprises at least the following steps
removing the inner metal sheet (406) in such a way that installation frames formed on the inner metal sheet are left in the wall structure,
removing the insulator layer (404) from a place where the inner metal sheet has been removed,
installing a wall element (420) comprising a metal sheet (422), an insulator layer (424) attached to the metal sheet and fast connectors (432) for sanitary fixtures in the place of the removed wall structure in such a way that the edges of the metal sheet (422) of the wall element are placed overlappingly with the installation frames.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the wall structure (202) is a fire proof wall structure.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the installation frame formed on the inner metal sheet (406) has a width of 10-100 mm.

### Claim 4 (depends on 1)

The method according to claim 1, at least two opposed edges of the metal sheet (422) of the wall element (420) are placed overlappingly with the installation frame.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the wall element (420) is attached to the installation frame using glue.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the wall structure (202) is a sound proof wall structure.

### Claim 7 (depends on 3)

The method according to claim 3, wherein the installation frame formed on the inner metal sheet (406) has a width of 30-60 mm.

### Claim 8 (depends on 7)

The method of according to claim 7, wherein the installation frame formed on the inner metal sheet (406) has a width of about 50 mm.
