Our 4, 8, & 11 gallon stainless buckets are the best metal mop buckets ever built. The 304 stainless steel used to manufacture the sides and the rolled, open rims that reinforce the bucket, is of the highest quality possible. This helps to prevent accumulation of dirt and bacteria. Exclusive one-piece construction keeps buckets leak-free and easy to sanitize. With proper care and maintenance, these buckets will last indefinitely.
