(OR) Landlord not fixing bathroom

The house I rented (lease started in July) is a 5 bed / 3 full bathrooms.

In one of the bathrooms, the shower has not worked since we moved in. Landlord has had people come look at the problem, and has admitted they don't have money to pay for the repair. It has been 3 months of me paying the rent rate for a 3 bathroom house. Since the other bathrooms are fine, is there anything I can do about our third bathroom shower not being functional? It leaks to the 2nd floor into one of the bedrooms. There is actually holes in the ceiling of the 2nd bedroom from it leaking before we moved in.

We have a big family which is why we opted to pay higher rent for a place with a 3rd bathroom vs something a few hundred bucks less that only had 2 bathrooms.

EDIT: They asked that if we paid for the repair (5k - 6k), if they could pay us back by reducing rent throughout the year. I asked if they could use our security deposit to pay for the repair (which was 6k) and they just replenish the deposit in that time. They said that is not possible, likely assumption that they have spent our deposit due to their money issues.
