I'm fairly sure this anthurium has bacterial blight (I've attached a photo in case I'm not correct). How can this be treated? I'd prefer to use home treatments rather than having to buy expensive sprays, etc.

The leaf discoloration you are seeing is a generic symptom that can be caused by improper watering, inadequate light and rarely, a fungal or bacterial problem.

I suspect that the problem is the repotting that you did into a container that is too large, that may not have drain holes and with a potting mix that is not sufficiently porous. All of those add up to the roots not getting adequate oxygen that they require because the excess soil and dense potting mix retain moisture at the expense of oxygen being able to penetrate into the root zone.

In addition, it is probably not receiving enough light where it is located in the corner. It should be more in front of the window.

FYI, bacterial and fungal problems are rare outside the greenhouse and can only be properly diagnosed with a lab test of the foliage or soil.
