Designed for Small to Extra Large Dogs. Made of 20 gauge 304 stainless steel for durability, and will never rust! Strong, durable and versatile. High back and sides protect against splashed and shaken water. The tub will have 3 port holes so you can use a 4" faucet or an 8" faucet for future use, if ever needed. It comes with a stainless still plug that matches the tub stainless so you can plug the port hole that is not being used.
