I agree about getting a bucket, but would also add that 5 gallons seems a little small. With a 5 gallon batch, you might have 4.5 gallons after the boil, but even then, you will need more room for the krausen to build up. Otherwise, you'll have a mess to clean up every time you ferment. Most starter kits come with a 6 or 6.5 gal. primary bucket.
